VDS-2500 - 2 video over 1 coax cable long range

This video signal transmission system is designed to transmit two video signals and two alarm signals from two cameras to perform monitoring using a single coaxial cable. This transmission reaches 800 meters distance.

Specifications
Two videos and two channels for transmitting alarm signals.
Sending DC power with 1.0A from viewer to sender for 2 cameras
reaching 800M of transmission length.
Selection of NC (normally closed) or NO (normally open) or
Terminal type from the input alarm sensor contact mode
The AC / DC power supply provides a stable and sufficient supply of 12 VDC to 2 cameras.
Sender's advanced power system provides a stable and sufficient power supply from 12 VDC to 2 cameras.
Powerful protection. In the event of a link failure or disconnection of the cable, the viewer does not continue to
send DC power to the shipper to prevent damage to all equipment.
When the coaxial link is false, the link alert signal can be transmitted to the external indicator of the viewer.
