Basic introduction:
One video signal corresponding to a monitor or VCR, If you want a camera image to the multiple people to look, recommended to choose video distributor. Because parallel video signal attenuation is large, for multiple output devices due to impedance mismatch after wait etc reason, images will seriously distorted and line is not stable.

In addition to video distributor impedance matching, as well as video gain, make the video signal at the same time for multiple output devices over short distances and is not affected, thus ensuring simultaneous video transmission to a certain extent. However, a coaxial cable for long distance transmission branch no practical effect.

For example, while the front of the camera to capture video signals can be accessed through the center of matrix video splitter, and then access DVR or display devices. Video distributor usually has an input two-output (ie, a forward 2), one into four, one into eight, and so on.

Usually video distributor in addition to providing multiple independent video output, both the video signal amplification function, it has also become a video distribution amplifier.

Video splitter with separate and isolate the complementary transistors or provided by an independent video amplifier IC 4-6 independent 75 ohm load capacity, including compatibility with a wide range and frequency response, and video inputs and outputs are BNC terminals.

In accordance with the use field it can be divided into: Meeting Video Splitter and security video distributor.
In accordance with the input and output channels can be divided into: Single-channel video splitter and multi-channel video distributor.

Action principle:
Video capture card is the most commonly device that used in video industry, depending on the needs of users, recommend different types of video capture card. Some can simultaneously capture multiple sources; some video capture cards can simultaneously output multiple video sources. Some users, but at the time of acquisition need transfer to multiple computers at the same time, this requires use video distributor.
