Outdoor Surveillance Cameras - Wireless

Wireless outdoor video cameras come in a wide variety of shapes and sizes with just as many features. Deciding which one is right for you will depend on the how you plan to use it and the environment in which it will be installed.The most important feature for security installations is the quality of the picture. With that in mind you will need to make certain the built-in wireless transmitter frequency has the capacity to deliver an exceptionally clear picture while maintaining resistance to interference. The reality is if you can't get a clear image from your wireless camera installation you may as well same your money and use a dummy camera (believe it or not the work pretty well as a visual deterrent).

The most common frequency used in home security installations with outdoor wireless cameras is 2.4gz. At this frequency the directional point to point antenna are capable of transmitting 380 TV lines up to 7miles but the 300ft models are more than enough for most home security installations. There are some limitations to directional antenna setups. The signal can penetrate walls, floors, ceilings, but doing so will limit the distance of the signal. A clear line of sight is required for distances in the 300ft range.

Another important consideration when choose a wireless outdoor camera is the lighting conditions. If your installation requires a camera capable of extreme low light conditions you will need to keep in mind that most night vision cameras operate do not operate well outside of the 7 meters range. This is an important consideration when you decide where to mount the camera.

The camera housing is as important as the camera itself because if it doesn't protect the hardware from the harsh outdoor elements your investment is lost. There are many good options available but we strongly suggest weatherproof Aluminum housing as the do not distort over time like many synthetic models we looked at. Aluminum housings are light weight, easy to handle and install and the hold up well in almost all weather conditions.
