1ch passive video transceiver, campact size, up to 1300m transmission distance if working with active video receiver.

 

Features:
Full-motion CCTV video at distance up to 300m when used with any passive Sectec transceiver or hub.
Up to 1200m if matching with active video reciever
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 300m
 

ST-VB201 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. It is easy to install and cost effective, and do not require power.

The compact size allows ST-VB201 to fit any where that the BNC can fit. It is ideal for mounting directly on virtually all high density DVR without any additional cabling. Its crosstalk and noise immunity ensure quality video signals.

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 300m. ST-VB201 series video transceiver also incorporates improved transient protection that eliminates the need for a ground screw.

ST-VB201 transceiver offers quality video in a compact size at a highly affordable price. They are idal for a wide variety of applications such as security, surveillance and video conferencing.
