Here is valid a principle too, that the more of light in monitored area we ensure, the more superior video record we get. It is practically possible to connect any camera to the transmitter and to transfer video signal remotely. The present wireless systems transfer video and audio signal to the distance of tens of meters in a built-up area and hundreds of meters in a direct visibility. Most of them operate in the band of 2,4 GHz or 1,2 GHz.
For transmission of video signal to the distance it is necessary to keep the following principles:
- choose the distance between receiver and transmitter as short as possible because even meters decide about the quality of transmission
- ideal status is if there is no obstacle between the antenna of transmitter and receiver
- choose the possibility of transmitter remote control, which brings smaller probability of discovering, jamming, lower demand for power supply of the system, longer time of recording.
Probable orientation ranges of transmitter according to effective radiated power for the band of 1,2 GHz and 2,4 GHz when using the common antenna of „truncheon“ type. Line according to: name prices producer cancel
