Video above shows live testing of 1 port AHD/TVI/cvi universal transmitter and receivers over real optical cable 20 km long. Video and Camera control via RS-485 PTZ works immediatelly without any delays.


Our AHD Video over Fiber Converters can simultaneously transmit 1 channel AHD/TVI/CVI video+1 channel RS-232/RS-485 data over fiber. Electronic and optical adjustments are never required. LED indicators are provided for instantly monitoring system status. Devices are available for either standalone or rack-mount installation, which is suitable for different working environment. Compatible with AHD-H, AHD-M, AHD-L / HD-TVI 720P & 1080P / HD-CVI 720P & 1080P, and even 2560 x 1920@25fps with video pixel ratios starting at 1280(H)x720(V)@30fps/1MPX and all the way up for 1.3mpx, 2mpx, 3mpx, 4mpx and 5mpx to support most up to date ultra HD modern security cameras.

Its optical module and core circuit adopt the imported components that have high stability, and all optical & electrical interfaces conform to the international standards, which is applied to the different working environment. This optical transceiver with video status indication can monitor the normal operation of system.
