Analog microwave transmission is to modulate the analog video signal directly on the microwave channel. The antenna transmits the RF current to the air by electromagnetic waves. The monitoring back end receives the electromagnetic wave signal through the antenna and receives the radio frequency current, and then demodulates and restores through the microwave receiver. After the signal is completed, wireless video surveillance can be implemented.
The frequency of analog microwaves is mainly from L-band 1.0-2.0GHz; S-band 2.3-2.7GHz; Ku-band 10.75-12.7GHz, each band of microwave equipment can be designed with different numbers of working frequency points (one for each group) Different transmission distances can be selected for different power devices. Supports one-way voice at the same time (receive the sound from the camera and the video back to the monitoring center through the microwave).
Analog transmission mode has no compression loss, reduced signal attenuation, strong real-time performance, can guarantee the transmission quality of video signals, and is suitable for point-to-point single-channel transmission. However, analog microwave is a point-to-point linear transmission, and the line of sight is open between two points. If there is an occlusion, the signal can be extended by back-to-back relay by adding the number of devices. The analog microwave does not need to be debugged, plug and play, and the installation and debugging are simple. Analog microwave has high carrier frequency, strong anti-interference ability, long transmission distance, no delay, reduced analog signal attenuation, and high video resolution.
