Wireless video transmitters are used when a physical connection between camera and recorder exceeds the cost of transmitting the video wirelessly. Another reason an installer might use a wireless transmitter is because the distance between the camera and recorder is greater than the distance electricity and power can be transmitted.
Even though wireless video surveillance is high in demand, a good understand of how the technology works is important when considering a wireless transmitter for your surveillance system. Some wireless video transmission systems offer a set number of frequencies in which an analog camera can operate. A wireless installation can reduce the cost of installing long distance cable, tubing, and trenching. It also gives users the freedom of installation the camera in different locations instead of being limited by a wire’s specifications.
A transmitter can be used for applications which require video be transmitted remotely. Applications such as mobile video deployment, construction site monitoring, ranches, undercover surveillance, can all benefit from the use of a wireless transmitter. Some radios are capable of streaming high resolution video up to 200 miles! Indoor radios are available for applications which don’t require the ruggedness you might need in the desert.
An indoor wireless transmitter for security cameras can transmit real time video 1000 feet and sometimes more using antennas. Before data and video was transmitted together, separate transmitters were used to send the signal which controls a moveable camera and the video. The technology used today lets users transmit both RS485 and video over one wireless link. A wireless transmitter kit can be purchased as a plug and play solution for most wireless applications. For those who need flexibility, transmitters/receivers can be purchase separately.
Analog video can penetrate walls and obstructions when using the right bandwidth. Different wavelengths are used for different applications. A 916MHz transmitter can be used for applications with large obstructions and high tree density. The 5.8GHz radios are excellent for long distance video transmission when no obstructions are present. These transmitters are called line of sight radios.
