เครื่องรับส่งวิดีโอแบบพาสซีฟ (TT222)

The TRANSVIDEO Model TT222 Video Transceiver is a passive (non-amplified) device that allows the transmission of real-time monochrome or color video over Unshielded Twisted-Pair (UTP) telephone wire. Baseband (composite) signals of any type are supported. An improvement over TRANSVIDEO's popular TT131 video transceiver, the passive TT222 features a Screwless UTP terminal block and Male BNC allowing connection directly to the camera or DVR.

It is capable of delivering a fully equalized signal to the DVR. When it used with video transmitter passive (non-amplified), It can applications under 250M. When used with any Active TRANSVIDEO Receiver, It can transmitted up 1KM. The TT222Video Transceiver also incorporates improved transient protection that eliminates the need for a ground screw. The unparalleled interference rejection and low emissions of the TT203 allow video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of a shared or existing cable plant.

Product advantages: 1\Far distance and high quality transmission. By using the advanced video processing technology\amplifying and compensating the video signals amplitude and the attenuation of different frequencies, it has maintained the original image's brightness and color. It has also achieved the good and long-range transmission of video signals. 2\Easy wiring and high utilization rate of cables.

A normal UTP cable, with 4 twisted pairs, can transmit 4 video signals simultaneously, or 3 channel video, 1 channel control the signal. Laying UTP cable is easier than laying the coaxial cable. 3, Using UTP cable instead of 75 ohm coaxial cable as a video signal transmission to ensure the quality and enhance the clarity of the image. Excellent capacity of the control of interference\surge and lightning protection. Improve the cables, utilization and reduce the cost of the project.
