1 channel passive video, audio& power transceiver. Video and audio transmission distance is 400m. Power transmission distance is max. 200m.

 
Overview
The ST-PVA223 video, audio& power balun is a passive (non-amplified) device that allows
the transmission of real-time CCTV video, audio& power balun signal via cost-effective Unshielded
Twisted Paired (UTP) cable. Baseband (composite) signals of any type are supported.
 
ST-PVA223 eliminates costly and bulky coaxial cable, allowing live CCTV color video signal up to 400m,
audio& power transmission up to 200m while used as a pair.
 
The superior interference rejection and low emissions of the ST-PVA223 allow video signals to coexist
in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of
a shared or existing cable plant.
 
ST-PVA223 has built-in surge suppression to protect video equipment against damaging voltage spikes.
Its crosstalk and noise immunity ensure quality video signals.
