More and more people are interested in setting up wireless security for their homes. There are a lot of reasons why this is so. 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 almost everywhere they feel that protection is needed -- and you do not have to worry about snaking wires inside the walls. The placement of a wireless 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? For example, you might have installed the camera but as soon as you turn it on, you cannot get the signal on the receiver. Fortunately, this type of problem can be easily solved. If you are thinking of doing the install on your own or with help from a friend, just remember that there are three frequencies now that you can choose from. 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. At the same time, this bandwidth will have minimal issues with other devices, which means that the signal can be transmitted strongly. The main disadvantage though is you will only have two channels available, so you are limited by this. * 2.4GHz wireless security cameras are the most common on the market. Unfortunately, there are tons of other devices out there (i.e. phones, computer routers, wireless keyboards) that use the same frequency. 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 stop working. 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. This is where the 5.8GHz transmitters and receivers come in. The 5.8GHz frequency is relatively clean, and subsequently, the successful wireless camera installation rate is higher. You can have up to eight analog wireless security cameras on 5.8GHz frequency. But the 5.8GHz frequency has an issue. It does not go through walls as effectively as the 900MHz or 2.4GHz frequency. This is a huge disadvantage. So right now, we have 900MHz, where you can only have two cameras on it (not very practical), and 2.4GHz, which has almost every device known to man on it, and 5.8GHz, which is relatively clean, but fails when you try to send the signal through walls. To get around these problems, the 5.8GHz systems are now being improved with better antennas and more powerful transmitters. That means these 5.8GHz systems can now go through walls as effectively as the lower bandwidth systems, without the device limitations. Current 5.8GHz cameras and receivers which start at below $200, usually will have a 10 milliwatt transmitter on it. If you have a clear line of sight, it can be extended to 300 feet but is really hard to do The signal strength is reduced by interference and walls. So if your objective is around 500 feet or so, look for a transmitter that is rated 100mw. For a distance greater than that, let's say 1,000 feet to 2,000 feet, you need a system with a one watt transmitter. These are very general numbers and can change based on the distance, weather, and availability of a clear line of sight. A good way to increase the odds of success is to put the security camera and receiver antenna as high as possible so that they have a clear line of sight. Before making any purchases however, make sure that you identify your own specific needs for a security system so that you receive the proper protection for your home or business. And if you still are not comfortable choosing the right system for your needs, just consult a professional!
