Cofdm Video Transmitter
Backpack Transmitter XK-J213T
XK-J213T Transmitter is a micro HD backpack video transmitter with two-way voice communication is a powerful and stable mobile video transmission system developed by Xingkai Tech. This system supports the functions of video transmission, two-way voice communication and data return. The signal adopts the third-party en/decryption, only the corresponding decrypted receiver can receive and demodulate the signal from the transmitter. Even if the receiving frequency of other receiver is the same as the transmitting frequency of the transmitter, it cannot demodulate the signal transmitted by this transmitter.
The transmitter supports multiple input modes, H.265 encoding and 1080P HD video quality.
The built-in voice Rx and Tx module is used in conjunction with the two-way voice receiver of the command center. The command center can easily contact the front end for intime direct and management. The voice encoding adopts automatic encryption, only the front-end transmitter can receive the center’s voice signal.
- Non-line-of-sight transmission, long transmission distance, and strong anti – interference capability.
