Video Expander / Frequency Shift Anti-interference Device
Video expander (frequency shift type) is a kind of transmission electronic product which can transmit unrepeatered video image signal in an ordinary video or radio-frequency wire cable for a distance of 1km utmost. The working principle of this product is to modulate 0-6M video signal to 40M radio-frequency signal, so as to avoid all kinds of interference signal sources (0-28M to a large extent).
It can be used widely in various places, such as elevators, factories and mines, electric power plant, aluminum workshops, roads, light pole monitoring, coal mines, tourist attractions, farms, mountainous areas and the coaches. It can mainly solve the tough anti-interference problems (including elevators, converting stations, electromotor, industrial converter and various high frequency electromagnetic interferences.)
The transmission distance varies depending on the different wire cables. The specific transmission distance is as follows:
1. All above-mentioned tests are carried out to ensure that the image effect can reach 420 lines.
2. All above-mentioned distance value is international standard wire cable testing value, and the actual transmission distance is related to the quality of the wire cable and the environmental temperature.
