Features:
Full-motion CCTV video at distance up to 350m when used with any passive Sectec transceiver or hub.
Up to 1500m if matching with active video balun
Mini-coax pigtail supports in-camera mounting in most dome cameras
Reliable screwless UTP terminal connection
No power required
Exceptional interference rejection
Built-in transient protection
Supports “ up-the-coax” type control signal up to 350m
Limited lifetime warranty
ST-VB203A series transceiver is a passive (non-amplified) device that allows the transmission of realtime
Monochrome or color video over unshielded twisted-pair (UTP) telephone wire. Baseband (composite) signal of any type are supported.
ST-VB203A series transceiver has a 9’’ mini-coax pigtail lead which allows in-camera enclosure mounting in most dome cameras and a great number of mounting options in general at both ends of the system. It is capable of delivering a fully equalized signal to the DVR when used with any active Sectec receiver, yet is compatible with all of Sectec passive products for applications under 350m. ST-VB203A series video transceiver also incorporates improved transient protection that eliminates the need for a ground screw.
The unparalleled interference rejection and low emissions of ST-VB203A series video balun allow video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of a shared or existing cable plant.
