CCTV Monitor System Video Anti-Interference Jamming / video amplifier

Detail CCTV Monitor System Video Anti-Interference Jamming / video amplifier

I. Product Introduction
Video expander (frequency shift type) is a kind of transmission electronic product which can transmit unrepeated utmost 1Km video image signal in an ordinary video or radio-frequency wire cable. The working principle of this product is to modulate 0-6M video signal to 40M radio-frequency signal, and 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.)
II. Transmission Distance of Frequency Shift Type Anti-interference (Video Expander)
Because of different wire cable features for different manufacturers, the transmission distance of the product also varies in the wire cables of different manufacturers.
Notice:
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.
How to solve the image warp, image pixel disorder, image with noise or image with interference?
Answer: This phenomenon results from too strong or too weak signal of the radio-frequency, please adjust radio-frequency gain knob (No. 4) to solve it.
How to solve the problem that the image is too bright or too dark?
Answer: Adjust No. 3 Knob to the image is normal.
Notice: This device is DC 12V supply, and working current 250mA.
Dimensions: 13.00*5.50*2.50cm
