Wireless video surveillance has become an important and integral part of our security system. To prevent unwanted and sudden terrorist attacks, malls, railway stations, airports, and other public and government places are always under surveillance. Besides the above, video surveillance is also common in industries to scrutinize parts of a process. The most common form of video surveillance is done with the help of CCTV's which you can obtain through your local provider in San Francisco, CA. These are also used for the surveillance of household security.

The use of CCTV cameras has some constraints. These CCTV cameras remain connected to a control panel with the help of wires and cables. These cables can easily get damaged by bad weather, accidents and can even get sabotaged. Moreover, it gets very difficult and costly to arrange for cables and wires for long-distance surveillance. Wired video or audio surveillance requires the presence of monitoring stations nearby the areas of surveillance. This will become a problem in case the focus of surveillance is always on the move. This problem is solved by wireless video surveillance which you can learn more about from your local dealer in San Francisco, CA.

Wireless surveillance not only makes surveillance easy but also increases the domain of surveillance. Wireless surveillance cameras work with the help of radars, signals and radio waves. The most common is the use of radio waves of different frequencies. These systems consist of small, hidden cameras that relay signals over short distances in the form of live images. So these have become quick, cost-effective security systems that will help us to boost our existing security system. In modern days there has been a shift from the traditional analog based CCTV towards a more digitalized surveillance. IP or Internet protocol cameras have revolutionized wireless surveillance by providing networked video surveillance and recording. These IP based cameras differ from their traditional counterparts in being wireless as well as they can receive and send data through the internet. They have encrypted radio technology and are therefore easy to install and easy for remote surveillance. A wide range of IP based surveillance cameras is available in the market. A camera can be chosen depending on the area of surveillance. For instance, the lowest Trango IP based camera can help in surveillance from as far as 40 miles away from the monitoring system. Then there is the WirelessGRID wptz IP based camera that is widely used in large areas for surveillance. While dealing with the advantages of using wireless and especially IP-based surveillance cameras in our security system, we must also take into account some of its disadvantages. These cameras are expensive and need a high network bandwidth for their functioning. These installations require specific technicians, and they are open to hacking as they transmit data through the internet. So it is best to use IP based surveillance for wireless security systems only when the use of CCTV cameras is not possible or may hinder public security.
