The use of wireless security cameras has become increasingly popular over recent years. This surge in interest is due to many reasons. Some people use wireless security cameras for their ease of installation. Other people use them because running wires is impossible or not cost effective. Whatever the reason may be, wireless security cameras are quickly becoming the preferred method of surveillance for many people.

Wireless security cameras are so popular because users can literally put them anywhere added protection is needed -- and the user doesn't have to worry about wires. The placement of a security system is very flexible and easy to install, as long as the installer does his or her homework. Wireless security cameras have a very high failure rate on initial install if precautions are not taken.

What sort of failure? Say you install the camera and give it power, but there is no signal picking up on the receiver side. Luckily, this problem can be solved with some due diligence. And when you are thinking about installing wireless security cameras (whether on your own or with some assistance), there are three frequencies that are on the market for the general public.

Choosing a Security System: 900MHz, 2.4GHz and 5.8GHz

The lower the frequency number, the more walls/objects your security system can pass through (except for concrete and metal).

  • 900MHz wireless security cameras can be used in installs where the signal has to go through trees or dry wall in order to reach the wireless receiver. This bandwidth doesn't have that much interference from other devices, and as a result, the signal can be relatively strong. The drawback is that right now there are only two channels available on this frequency, making its use very limited.
  • 2.4GHz wireless security cameras are the most common on the market. So are 2.4GHz phones, wireless routers, keyboards, and mice that we all use. Basically, if you see something wireless on the market, there is a good chance it is on a 2.4GHz frequency. As a result, a lot of the wireless 2.4GHz security cameras fail. There are up to 12 channels available on 2.4GHz frequency that you can select for transmission, but the reality is that if you live in a city like New York or Los Angeles you won't find a single channel that is not occupied by a wireless device.
