Data-Link™ Viewer & Sender

One of a family of fine products, the DATA LINK can send high quality CCTV signals with a protocol independent RS485 half duplex data stream and configurable alarm data channel (not just contact closure and can cope with multiple inputs) all on ONE coaxial cable. 12 volt DC power for cameras and accessories is also provided down the SAME coaxial cable.

SNT’s Data Link System allows one coaxial cable to be used for the simultaneous conveyance of a high quality video channel, RS485 data channel, alarm signal data channel, status monitor channel and DC power in real time.

Data Link assures excellent signal quality, irrespective of distance, thanks to the unique fully automatic equalization and correction system. Operating distances may be up to 600 metres whilst providing 12V DC power to the camera. The half duplex RS485 channel may be utilised for remote camera set-up/adjustment, access control etc.

Comprising of two main parts; the remote unit (sender) is connected to the camera and local unit (viewer) is connected to the control operating system.

Data Link provides the innovation, simple installation and excellent picture quality that you expect from SNT products. Data Link has complete power and misconnection protection circuitry and eliminates and protects from hum interference and ground loop problems.
