Product Description

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.

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.
