The twisted tuning transmitter generally refers to a device that uses network cables to transmit videos. The twisted transmission uses the principle of differential transmission. The video signal is converted to the video signal with the same range and the opposite of the polarity on the transmitt.The video signal of the two polarity opposite to the opposite side becomes a normal video signal.For the processing of video signals, the image signal transmitted is clearer than the coaxial cable, and there will be no interference between the same network cable.
Principles of twisted transmission transmission
The basic principle is used to transmit video signals with twisted twisted wire transmission. The usual video signal is a non -balanced way of video baseband signal that is suitable for transmission in non -balanced transmission methods such as coaxial cables.The twin tie is a cable with a balanced transmission method. It is precisely because of the mode of balanced transmission and cable twisted, which makes the twisted twisted wire transmission have strong anti -interference capabilities. ThereforeThe video signal must be converted into a balanced signal.
Parameter parameters of twisted wiring
Work parameters of the twisted transmission transmission: input voltage: DC24 input current: 1.5A Transmission distance: 0-100 meters output voltage: DC12V supply current: for two dot lattice lights
Pricer price
Come by transmission distance.About 400 yuan for 100 meters.About 450 meters away.About 300 meters of about 500 yuan.600 meters of 600 points.If you are not Party A, it is generally not higher than this price when purchasing.
Twist tuning transmission method
The video signal line is only two, but one line can solve the four camera wiring problems BNC welding. Just find the iron soldering iron welding (find a welded experience) camera power cord, access the Internet or to electronics to electronicsThe camera power cord purchased by the city must be connected to the 12V transformer and 30 cameras. You can use more than 3V15A transformers, a group of 10 cameras (or 6 and 8 groups, allocate by yourself).
