If you have a two story home or are moving your business to a larger location, you'll want to know all you can about remote video surveillance. These systems will also you to monitor all of the activity that goes on around your home or business, and will give you more evidence to present to the police if your property has been broken into.
Digital Video Recorders, or DVR devices, will help you to look at all the possible angles of your property any time you need to. You can install as many cameras as you need to in different areas of your home, and most of the systems are very easy to install. You will have to run each of the camera cables from the back of the DVR device and plug them into a computer monitor, and then you'll be able to see several small screens showcasing each area of your home or business.
In order for the DVR system to function properly, you will also have to have a video card that you install onto your computer for remote video surveillance. These cards are easy to install as well, but you'll need to ask your surveillance provider which cards will work best with the software that you already have.
If you're not sure which remote video surveillance devices to choose, you should think about how many cameras you want to install to your monitor. This is most likely determined by how large your property is, and whether or not you are in a business where high security is needed, such as a jewelry store.
The frames per second (fps)on the security surveillance equipment will also help you to make your decision. You want to be able to clearly decipher any suspicious movement or activity on your property, and if you are running a business or have valuables in your home, you'll want to purchase a system with a high fps, so that you won't miss any activity.
If you know that you have a computer you can use just for security purposes, it is best to purchase the computer card system for your remote video surveillance. A standalone system is best if you still want your security system to be computer based, and have hardware and software that is compatible with the alarm system. This way, you can use your computer for business use and to monitor your security system.

Home Video Security Systems
Home video security systems can be bought in either a kit as an out-of-the-box designed system or a custom designed system to fit your household needs. Both options provide their own lists of pros and cons. The purpose of this article is to help you understand what the specific components are that go into making up a home video security system. There are basically six categories that make up a home video security customized solution.
The first category has to do with Digital Video Recorders. There are three things to look for when researching Digital Video Recorders:
1-Brand name-We suggest that go with brand names that are prominent in the electronics industry like Sony.
2-Memory-We suggest you try to get the most memory available within your budget.
3-Number of channels-The number of channels are how many cameras can be hooked up to the Digital Video Recorder. For example if the Digital Video Recorder specs say it's a four channel Digital Video Recorder then it may record up to four cameras.
The second category in choosing components for your home video security system is cameras. Here are a list of types of cameras:
1-Bullet
2-Dome
3-Spy/Covert
Some of the main features are:
1-Image sensor manufacturer-Again here we suggest going with a name brand like Sony.
2-Lens size-The lens size will determine view angle and distance. If you desire a lens that does not have a fixed distance then look for a camera with a "varifocal lens".
3-Resolution-Resolution measures the cameras ability to reproduce an image. The higher the resolution, the better the picture quality.
4-IR/Infrared-These types of cameras are becoming increasingly popular and are especially important for outdoor surveillance systems. Again the main difference between IR cameras is the distance specs.
The third category for your home video security is the type of cabling you will need. Most out of the box systems will provide the cables you need, but what if you need longer cables or shorter ones? One of the many benefits of buying a custom system is that you can choose the cabling necessary to fit your specific home video security application.
The fourth category is the monitor. Remember these things when looking at monitors:
1-They are totally optional.
2-Most Digital Video Recorders will allow you to use any standard TV or computer monitor.
3-Switches will allow you to channel multiple cameras onto your monitor so you can split your screen and watch multiple cameras at the same time.
4-Again check your Digital Video Recorder specs.
Fifth, consider the types of accessories that you will need. The most common accessories are the following:
1-Stickers
2-Wall mounts
3-Brackets
And finally the sixth category for your home video security package is your power supply. Each type of camera you use will have its own power supply spec so make sure you check the camera specs. You don't want to run out of power when you need it the most.
Hopefully I have been able to break down all the various components for your home video security system into an easy to understand process. Now you will have to do the homework and do further research on each of the six categories. And remember to consult with an expert when needed.

Monitor Your Babies and Children with Video Home Security Systems
The use of video home security systems may not uncommon for many people. However, there are many more people who still doubt the usefulness of the system. This article is provided for them to give some view about the system.
Having a new infant into the home brings a whole new set of home security concerns to the minds of parents. There is so much to learn, and not all of it can be learned from baby books. Besides worrying about external threats to your family's safety like intruders, there are many safety concerns which must be dealt with right within your four walls. Infants are delicate creatures, and as such need a high level of attention and care meaning parents' stress levels will be up, and likely energy down from reduced hours of sleep and strain. All of these things are part of raising children, and bring many parents joy despite the long hours and difficult moments. In order to best ensure that no matter how you are feeling your baby is safe is to take extra precautions preparing the house for baby's safety before he or she arrives. Today, technology can also be a huge help. One such example is that of video baby monitors. In the past, parents only had audio feedback about how baby is doing alone in his or her room, but today the infant can be video monitored from any part of the house live and instantaneously.
Of course such home security measures are never an excuse to leave the child alone except for naptime or bedtime, and the presence of a visual image is never a substitute for actual vigilance. However, when in the protected environment of the crib, many parents feel perfectly safe letting baby spend the night solo. The peace and quiet of the environment helps the infant to rest quickly and quietly, and develops good sleeping habits that will be even more beneficial to the parents later in life. For such occasions, video baby monitoring systems have been invented. These systems are generally wireless and portable, meaning they can be transported around the house. They can be brought downstairs while mom and dad watch TV in the evening, or placed by the bed at night. The system works with a receiver and a transmitter than send not only video but audio of your baby in real time. The half of the system actually present with your infant is generally quite compact consisting of only a camera and a microphone, while the receiver on your end will be quite a bit larger with a monitor and speaker to playback the images and sound.
Many families prefer to leave such devices on at all times, but this can increase the risk of an incidence of the power dying down rapidly during the night. For this reason, many families prefer baby video home security systems which are programmed to turn on automatically when activated by a sound or movement. Every time the infant rolls over or cries the system comes on, and the parent is notified by the unit. To get even more intense about infant home security, many families hook their monitor systems up to a bedroom television while they sleep, so the picture is clear and large, or even set up more than one transmitter from various angles for full coverage with a split-screen receiver system.
Those worried about privacy when projecting images of baby digitally around the house can rest at ease with 'secure line' systems. These systems minimize interference from other signal sources like radios, cell phones and Wi-Fi internet, and eliminate the risk of neighbors or eavesdroppers picking up a signal. A digital signal is the most secure, and will provide the most clear sound and image free from background or electronic noises like dull buzzing or static.

Video Intercom System For Home Security
Video intercom systems for home security are increasingly becoming more cheaply available and now can be found in many average homes. While audio intercoms have long been popular devices, video intercoms until recently were the territory of only wealthy and advantages homeowners; no longer is this the case.
The concept behind video intercoms is that by your buzzer or doorbell, you have a small camera which allows you to check who exactly it is outside before you decide to let them in. Essentially then it's similar to having a spy-hole built into your door but for longer ranges and so is particularly useful for those who have a long front drive with gates, or those who live in flats, both of which would make it difficult to see the visitor through a window. This can be useful for many reasons and can highly improve the safety of you and your family.
Firstly, video intercoms allow you to check the appearance of your visitors before you decide to let them in. While they say never to judge a book by its cover, this can mean that you don't let in large gangs of youths when you're not expecting them or it's late at night. Furthermore it allows you to check that the visitor is who they say they are, and you can even ask them to show ID to the camera before you let them in.
Normally to do either of these things you would be forced to present yourself by going outside and seeing or speaking to your guest - even with audio intercom systems you are required to answer the phone system in order to speak with them which will alert them to your presence. Similarly, attempting to spy guests through the window can be risky if it means they might see you.
Once you've alerted people waiting outside to your presence, it can make them quite agitated if you then refuse to answer the door or let them in. For the elderly particularly, or those in rough areas, this can then lead to trouble. Fortunately, all that can be avoided with a video intercom which allows the user to simply look at the screen in order to see who's waiting outside before deciding whether or not to speak to them.
Video intercoms have many other uses however, particularly for the unsociable (guilty!). Sometimes it may simply be the case that you don't feel like visitors, or talking to that annoying neighbour, in which case video intercoms can be a real Godsend.
Making them even more practical today is the fact that many of the video intercom systems available on the market now come as do-it-yourself style packages that require some basic construction upon delivery. This saves on costs and also means that you can adapt them to the layout of your front door and gates without having to pay for hired professionals.
Overall then, video intercoms make an affordable and highly useful part of any home security plan that many of the general public simply do not consider. If you're looking to revamp your home security then they are a great option that will also look high-tech to impress your guests... if they ever get inside that is.

A Home Video Surveillance System
Protecting your home has become more a concern for many people these days. Many people are still installing home security systems. Others are choosing to install home video surveillance systems for the benefits that they offer that other systems do not.
One benefit of this type of system is that you can record everything that is going on around your home. This means that if someone was to try and break-in, or did break-in, you would have a video image of the person(s) who committed the crime. This will help when it comes to prosecuting the criminals that are caught. Another great benefit is that many can be viewed from remote locations over the internet. This is a great way to continue watching out for your home even while you are away.
This type of system is fairly easy to use too. Once it is install you simply turn the cameras on when you are leaving or whenever you want it on. Some systems even have motor detector sensors which will activate the cameras any time movement is picked up by the sensor. You can use this system with a security system as well.
The cost for these types of systems vary although you should expect to pay at least a couple thousand dollars for one. The higher technology systems, such as the motion detector sensors, will cost even more. However knowing that your home is safe and that you can catch the perpetrator in the event of a break-in is well worth the cost of the system.

Wireless Video Security System - A Technology Explained
Video systems are becoming a part of our everyday lives. When video surveillance systems first hit the market in the mid 80's, they immediately made a major impact on crime prevention and the way crimes are investigated. Early video systems required a hardwired connection between the camera and the recording system. Recent innovations in wireless video transmission are changing that requirement.
Wireless video systems are popping up all over the place to satisfy a range of consumer requirements. From wireless baby monitors to high-end high-definition wireless broadcast systems, wireless video systems are available in a wide range of prices, features and functions.
Most modern, consumer grade wireless video systems will fall into one of the following frequencies; 900 MHz, 2.4 GHZ or 5.8 GHz. Almost all of the affordable consumer grade wireless cameras on the market fall into the 2.4 GHz range.
Every wireless video system consists of a camera, a transmitter, a receiver, an antenna and a power supply. Transmission ranges can vary greatly depending on the frequency, the antenna and the rated power output.
With the exception of higher end, high power broadcast quality systems; most wireless video systems do not require a license from the Federal Communication Commission (FCC) to operate. No matter what frequency you plan on using, if you are installing a high powered installation, especially near a highway or an airport, you should secure the appropriate FCC license.
For the best results and the longest range, most wireless video transmission systems require a clear line of site between the transmitter and the receiver to operate consistently. Wireless video signals do not penetrate very well through glass, walls, concrete, trees, steel or other obstructions.
In addition, other RF signals around the same frequency can cause interference or be interfered with by wireless video systems. In the 2.4 GHz range popular with most security applications, interference can be experienced between cordless phones, microwave ovens, local television broadcasts, computer monitors, power supplies or wireless LAN/WANs. Sometimes interference problems can be solved by re-locating the transmitters or receivers.
Since 90% of consumer grade wireless video systems fall into the 2.4 GHz category, we will discuss the features of both the 2.4 GHz analog and digital systems and the limitations and benefits of each.
The entire 2.4 GHZ bandwidth allocated for consumer use is from 2,412 MHz to 2,462 MHz. As per the FCC standards, there are 11 possible channels which are 22 MHz wide with a 5 MHz spacing interval between each.
In order to allow multiple cameras on the same system, residential, consumer grade 2.4 GHz analog video transmitters such as a wireless baby monitor or a front door camera require fixed frequency, non-overlapping channels to reduce interference.
These 2.4 GHz analog wireless cameras are some of the most popular video surveillance systems for consumers and end users, yet very few professional security providers will offer these wireless cameras.
At best, professional security installers consider the 2.4 GHz analog video systems as low-end residential solutions which are notoriously unreliable. The analog 2.4 GHz cameras are easily identified by their price tag which is usually in the $ 69.00 to $ 140.00 range per camera.
If you take away the benefit of their low cost, there are several inherent limitations to Analog 2.4 GHz video transmission including:
In the 2.4 GHz range, there are only 4 available non-overlapping channels. This limits these systems to a total of 4-cameras, each of which is tuned to a different pre-defined frequency. Each of these fixed frequencies is capable of transmitting about 11 mega-bits per second of data (Mbps).
Because the analog 2.4 GHz wireless video transmitters are on fixed frequencies, they are especially susceptible to interference from outside sources. A typical transmission range for an analog 2.4 GHz wireless video link is about 200 to 300 feet when installed outdoors with a clear line of site. The relative transmission distance is greatly reduced when installed indoors with some lower end analog systems typically providing about 10-30 feet.
Since these cameras are transmitted on a fixed, un-secured open frequency, the signal is easily intercepted and can be seen by anyone with a 2.4 GHz 4-channel receiver. A voyeur or a burglar could simply drive around a neighborhood with a receiver and see inside your home. If you have one of these systems installed, perhaps a burglar is watching you right now.
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) created the first Wireless Local Area Network (WLAN) standard which was named 802.11. The original 802.11 utilized the 2.4 GHz frequency to allow reliable transmission of 2-Mbps of bandwidth. In 1999, the standard was upgraded to 802.11b which supports up to 11 Mega-Bits per Second (Mbps) which was comparable to traditional Ethernet connectivity speeds.
The 802.11 protocol works by sub-dividing the entire 2.4 GHz frequency into channels and switching between them during transmissions. As the signal is sent, it sends a packet of data at one frequency and then hops to the next channel and sends another packet and so on, until the entire data package is sent.
In 2003, WLAN products began supporting a new 2.4 GHz wireless standard called 802.11g which supports a bandwidth of 108 Mbps of data. The days of cost effective, reliable and secure wireless video transmission have finally arrived.
The added features and benefits of using internet protocol cameras and 802.11g for wireless video transmission in a security application are many.
The 802.11g protocol utilizes digital bi-directional signals which support the use of pan/tilt/zoom functions and presets found in many newer cameras. The digital signal used is duplex (bi-directional) as opposed to the simplex (one-way) binary signal used in analog type systems.
Because 802.11g utilizes the entire 2.4 GHz frequency spectrum, interference is greatly reduced and longer transmission ranges can be expected. If an area of the frequency is noisy then the transmitter/receivers will adapt the signal by sending smaller packets in the noisy affected area and larger packets in the non-effected areas of the frequency. A wireless IP video system will offer almost the same performance as a professional grade wired system with a reliable transmission range of 150-200 feet.
If the camera is to be located further than 200 feet, directional antennas are available which can increase the distance to 600 or more feet. If a greater distance than 600 feet is required, point to point, long range directional type systems can increase the distance to several miles.
In addition to standard 64/128-bit WEP Security, 802.11g protocol allows data packets to be encrypted using a 40-bit RCA key. When considered in conjunction with the inherent security built into DSSS spread spectrum technology, the data signals are at least as secure as data traveling over a wired network.
The 802.11g protocol can support a much larger number of wireless cameras by using a medium access control or MAC layer called CSMA/CA or Carrier Sense Multiple Access/Collision Avoidance. The collision avoidance in 802.11g supports the use of CTS/RTS signals (clear to send/ready to send) which tell each camera on the system when it is O.K. to begin transmitting or receiving data thereby avoiding interference.
Any hardwired IP Camera that is installed on your intranet or internet that is using the same CODEC (Coding & Decoding) algorithm can be integrated into the same software viewing and recording system.
An IP addressable camera system can be viewed or recorded from a properly equipped computer from any location in the world. This can allow you the freedom to move anywhere on the planet while still keeping track of your assets. In addition, if you ever decide to move your head end recording equipment to a different location, you simply pick it up and move it. No wires to re-route.
One thing to remember when deploying a multi-camera wireless IP based video system is that processing multiple streaming video signals places a substantial work load on a computers CPU.
Hard Wired systems have video capture cards which are installed in the PC/DVR. These cards take up to half of the work load off the computers CPU. Because wireless IP video systems do not have the help of these capture boards, the computers CPU must handle 100% of the processing workload.
What this means is that as you add cameras to a wireless system the total frame rate or the total images per second which can be viewed and recorded will decline due to the increased workload.
Some people shy away from IP and network security solutions because they appear to be complicated and difficult to set up. The fact is the initial set up does require some expertise and knowledge but the operation and day to day use of the systems are no different than using any other PC based security camera system. The required computer skills are minimal. If a person can check email, use a word processing program or load and play any type of game on a PC they most likely possess the skills needed to use and manage a PC based system.

A voyeur or a burglar could simply drive around a neighborhood with a receiver and see inside your home. If you have one of these systems installed, perhaps a burglar is watching you right now.
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) created the first Wireless Local Area Network (WLAN) standard which was named 802.11. The original 802.11 utilized the 2.4 GHz frequency to allow reliable transmission of 2-Mbps of bandwidth. In 1999, the standard was upgraded to 802.11b which supports up to 11 Mega-Bits per Second (Mbps) which was comparable to traditional Ethernet connectivity speeds.
The 802.11 protocol works by sub-dividing the entire 2.4 GHz frequency into channels and switching between them during transmissions. As the signal is sent, it sends a packet of data at one frequency and then hops to the next channel and sends another packet and so on, until the entire data package is sent.
In 2003, WLAN products began supporting a new 2.4 GHz wireless standard called 802.11g which supports a bandwidth of 108 Mbps of data. The days of cost effective, reliable and secure wireless video transmission have finally arrived.
The added features and benefits of using internet protocol cameras and 802.11g for wireless video transmission in a security application are many.
The 802.11g protocol utilizes digital bi-directional signals which support the use of pan/tilt/zoom functions and presets found in many newer cameras. The digital signal used is duplex (bi-directional) as opposed to the simplex (one-way) binary signal used in analog type systems.
Because 802.11g utilizes the entire 2.4 GHz frequency spectrum, interference is greatly reduced and longer transmission ranges can be expected. If an area of the frequency is noisy then the transmitter/receivers will adapt the signal by sending smaller packets in the noisy affected area and larger packets in the non-effected areas of the frequency. A wireless IP video system will offer almost the same performance as a professional grade wired system with a reliable transmission range of 150-200 feet.
If the camera is to be located further than 200 feet, directional antennas are available which can increase the distance to 600 or more feet. If a greater distance than 600 feet is required, point to point, long range directional type systems can increase the distance to several miles.
In addition to standard 64/128-bit WEP Security, 802.11g protocol allows data packets to be encrypted using a 40-bit RCA key. When considered in conjunction with the inherent security built into DSSS spread spectrum technology, the data signals are at least as secure as data traveling over a wired network.
The 802.11g protocol can support a much larger number of wireless cameras by using a medium access control or MAC layer called CSMA/CA or Carrier Sense Multiple Access/Collision Avoidance. The collision avoidance in 802.11g supports the use of CTS/RTS signals (clear to send/ready to send) which tell each camera on the system when it is O.K. to begin transmitting or receiving data thereby avoiding interference.
Any hardwired IP Camera that is installed on your intranet or internet that is using the same CODEC (Coding & Decoding) algorithm can be integrated into the same software viewing and recording system.
An IP addressable camera system can be viewed or recorded from a properly equipped computer from any location in the world. This can allow you the freedom to move anywhere on the planet while still keeping track of your assets. In addition, if you ever decide to move your head end recording equipment to a different location, you simply pick it up and move it. No wires to re-route.
One thing to remember when deploying a multi-camera wireless IP based video system is that processing multiple streaming video signals places a substantial work load on a computers CPU.
Hard Wired systems have video capture cards which are installed in the PC/DVR. These cards take up to half of the work load off the computers CPU. Because wireless IP video systems do not have the help of these capture boards, the computers CPU must handle 100% of the processing workload.
What this means is that as you add cameras to a wireless system the total frame rate or the total images per second which can be viewed and recorded will decline due to the increased workload.
Some people shy away from IP and network security solutions because they appear to be complicated and difficult to set up. The fact is the initial set up does require some expertise and knowledge but the operation and day to day use of the systems are no different than using any other PC based security camera system. The required computer skills are minimal. If a person can check email, use a word processing program or load and play any type of game on a PC they most likely possess the skills needed to use and manage a PC based system.

Wireless Video Security System - How to Choose One for Your Home Needs
Choosing a wireless video security system can be confusing. There are indoor and outdoor cameras, spy cameras and surveillance cameras, closed circuit cameras and PC based closed circuit systems, and various recording methods. Ordinarily, this system is part of a comprehensive home security system.
Wireless video security system technology becomes better and more affordable every year. But you still need to keep in mind that you get what you pay for. The least expensive security camera choices might not be good enough to do what you need and capture the picture quality you want.
The question you will need to answer first is "What do I need to monitor?" Do you want to know what is happening outside your home, or inside? Do you want to record an intruder? Are you trying to prevent vandalism or break-ins? Do you want a record of what happens between a babysitter and your children or a caregiver and your parent? Answering these questions will determine the type of video security system you need.
The next question is whether it matters if the camera(s) in your video security system is visible. Do you want an exterior surveillance camera that will be a deterrent to potential intruders? If this is what you need, you can find one for as little as $100 to $150. On the other end of the scale, a high-end wireless exterior camera could cost as much as $1500. These will probably be closed circuit TV cameras (CCTV). As is true of any camera, the quality of the pictures is determined by the quality of the lens. Some will be fixed at a single angle. Others will be movable.
The images captured by the cameras in your video security system will be captured on video tape (VCR) or on a DVD (DVR technology). Some systems are equipped with sensors that actually record images only when a sensor is activated (by motion, for example). This saves recording time and wasted recording. The system might connect cameras to a DVR device or it might connect them to your PC's hard drive.
Wireless interior video security systems can be motion activated or sound activated. They can be set on timers or they can run 24/7. These cameras can be visible or they can be spy cameras that are virtually undetectable. The camera might be hidden in a anything from a clock to a tiny pinhole in the wall or ceiling. Cameras can be hidden in sensors and monitors that provide other functions in your security system.
Choosing a video security system will need to consider your needs, your budget, and installation and connection issues. Keep in mind that the system as a whole is only as good as the lowest quality component.
Then consult with a professional in choosing the system that is right for you. If your wireless video security system will be part of a more comprehensive security system, you will certainly want to have it professionally installed. This might also be the case if you are installing exterior cameras. For a single spy camera, however - especially if the system is wireless - you might be able to handle installation on your own.

Set Your Wireless Video Surveillance System
Set your wireless video surveillance system is not as difficult as you might think. As technology has increased, cameras are getting better picture and sound, and have become quite simple for homeowners to install themselves. In most cases, all you need to do is find a good camera kit and follow the instructions! Here are a few tips for setting up your home security cameras.
1. Security Check
First, determine where you need cameras. Common areas to keep an eye on are front and back doors, and other points of entry that are hidden from view. You may want to have a few that monitor your backyard, garage area or other areas where a burglar can come on to your property. Keep in mind that the cameras will need to be placed at appropriate distances, so they have a clear, focused view of the area you want to watch. Take a few measurements, so you know the areas that you want covered.
2. Camera Selection
You can purchase home security camera kits at many home and electronics stores, but be sure to read the specs before you buy. Make sure they can be set to cover the areas you need. Also, make sure that you can add to this system if you want to install more cameras later on. Understand that wireless cameras still require a power wire, and need to be relatively close to outlets... usually about 4-6 feet. You may want to consider getting cameras that have pan and tilt capability, so you can move the cameras remotely and scan a larger area.
3. Installing Your System
If you're concerned about wire tampering, consider having a professional install your cameras. They can drill inside your walls, so your power cords, outlets and adaptors are concealed. To mount your cameras, simply drill into your walls and use screws to mount them. For outdoor cameras, protect them with a weatherproof housing.
4. Set-Up
Each camera needs to be set to its own channel. Usually, these are lettered or numbered. So your front door camera could be channel A, and your back door camera channel B.
Put the wireless receiver next to your TV and connect it with the supplied cables. If you prefer to have your security cameras hooked up to your computer or DVR, you can do this as well (as long as your system supports it). You can connect your security cameras to your computer using digital video capture devices.
Once you're connected, make sure you can view all of your cameras and that the view is as you want it. Go through each camera, and adjust the viewing angle as needed.
5. Monitoring
You can hook up a VCR or DVR to record from your TV. Or, if you are using a computer to monitor your home video surveillance system, use video capture software so you can keep an eye on your home over the internet. This is a great feature if you are away from home frequently.

Wired or Wireless Video Surveillance Systems, What's the Difference?
When it comes to video surveillance, the security of your business is the deciding factor. So, read on if you want to go for wired or wireless video surveillance.
When wireless video surveillance counts
With wireless video surveillance systems, you can do two things at the same time. You can go over your receipts and check on your kitchen staff in the comfort of your own office. This saves you time from going to the kitchen just to see how work is progressing when urgent paper work needs to be done. The convenience of monitoring the waiters and the counter people is also yours with a wireless video surveillance system. By adding additional cameras, you can also have an electronic eye keeping watch over the cash register and the restaurant's entrance and exits.
The flexibility of the wireless video surveillance system is enhanced when you add a mobile viewer. You can see all the important nooks and crannies whether you are in the office, in the kitchen, or at the counter. This will deter your staff from loitering or wasting their time, so you get your money's worth for their services. Like other restaurant owners, you want to prevent theft in the kitchen and at the cash register. A wireless video surveillance will give you piece of mind and control over your business.
Going fully wired
The advantage of going for wired video surveillance system is the confidence that a particular quarter of your restaurant is permanently covered. Other areas in the restaurant that needs your constant scrutiny are the cash register, bar, wine cellar, front door, and exits. A wired surveillance camera cannot be transferred from the kitchen to the cash register, so you have to add more cameras and have these installed in these important areas. The wired and wireless video surveillance versions give the same advantages when it comes to your business security.
Wired or wireless?
The option to go wired or wireless may depend on your needs and convenience. Many restaurant owners get both versions. The also get the pan-tilt surveillance cameras to get more viewing angles. The infrared cameras are also a hit for outdoor surveillance.
Depending on your budget, you can start with a four camera package or go full time with 16 cameras - whether your system is PC or DVR based. Wired or wireless, you can be flexible. If you want to be discreet about your surveillance, go wireless. This will cost more, though. However, in consideration of your dine-in customers, this will be just perfect. In addition, a wireless system installation will blend well with your interior.
Cost versus security
Surveillance security systems may not prevent accidents from happening, but you and your staff can be alerted immediately to prevent more damage from happening. Petty theft can be averted and your staff will be encouraged to perform better. It is not cheap to have a system installed, whether it is wired or wireless video surveillance. It will all depend on the number and type of camera you will get, and the floor area of the establishment. A package may cost anywhere from $2,000 to $25,000. Wired or wireless, the installation per camera will run from $500 to $1,000.
Indeed, when it is about security and your business, penny pinching is non-negotiable.
