Night Vision Security Cameras - The Art of Security and Protection

Whether you are looking to provide security and protection in your home or at the office, whether it is outdoors or in a dark spot inside, night vision security cameras will give you an absolutely clear vision into the darkness. Even in complete darkness, night vision security cameras produce a clear view of the area where you want surveillance. It is the ultimate in overseeing those areas where you are concerned that you may be vulnerable.

Where can the cameras be aimed?

You can watch any outside area, especially those places where there are entrances or valuable items. We normally think of outside surveillance aimed at doors, decks, parking lots, driveways and back yards. But you can also put a camera in an attic, a garage, a nursery or a basement. Put a camera anywhere that you are concerned about.

What is available?

You can purchase night vision security cameras as a complete package or as individual components. A package operates multiple cameras and come in sizes from four to sixteen cameras. A complete package includes the cameras, the digital video recorder (DVR) and all of the cables necessary to make your system operational.

How does it work?

Night vision security cameras can operate in color during daytime hours. At night, however, they operate as a black and white TV signal. The camera emits an infrared signal that "lights up" the covered area, gets reflected back to the camera and is picked up as a black and white image. The signal is transmitted to the DVR where it is recorded.

The DVR processes the video images which you can watch as they happen or watch later from the video record. A TV, monitor or PC can be directly connected to the DVR or the signal can be fed to a more complex monitoring station.

This technology has been around for many years. In the last several years the prices for night vision security cameras have really come down and have now reached the level where an individual family or a small business can easily afford to install one of these systems. And as a result, we are starting to see more and more of these packages around the country.

What about the components?

Selecting the right system for you depends on the areas you want to watch. You need to determine what and how many areas you wish to watch. That will determine how many cameras you will need to install.

Next, you need to measure how large the surveilled area is and how far into the area you need to see. Different night vision security cameras can view further into the darkness. Some cameras are for very short distances, even as close as 10 feet. Other cameras will see up to 100 feet into the darkness. A common distance for a home installation is about 25 feet into the dark.
