OEM 2 Channel AHD Video to Fiber Optic media converter/ RS485/Ethernet/audio,Video optical transmitter and receiver
Description
Series fiber video multiplexers transmit 1-channel of broadcast quality video using 8-bit digitally
encoding and decoding over one multimode or single-mode optical fiber. The modules are directly compatible
with NTSC, PAL or SECAM CCTV camera systems. These multiplexer units are typically used in applications
that have fixed cameras. 1 return rs485 data is optional.
Plug and Play design ensures adjustment-free installation and operation, and optical adjustments are never
required. A typical installation utilizes a 1-channel transmitter unit at the camera end of the link, connected via
a single fiber optic cable, to a 1-channel receiver unit at the monitoring end of the link. Devices are available
for either standalone or rack mount installation. The units incorporate LED indicators for monitoring the power and video operating status.
