Transmission distance extension using DoubleReach™

The Ultimate performance PoC DVR’s DoubleReach™ is a new technology for HD-SDI video transmission. This technology compresses Full-HD video to the undistinguishable video level by naked eye, and it extends HD-SDI transmission distance by two times (up to 400m) when it compared with conventional HD-SDI.

HD DVR models which support DoubleReach can receive DoubleReach video for odd channels without additional equipment, and users can easily relocate channels which are displayed on multi-screen. To use this function, camera needs DoubleReach transmitter DR101P-TX, and it can work together with PoC repeater RP101P.

This technology is especially useful when it comes to upgrading existing system. Because DoubleReach^TM technology changes the HD-SDI’s video data from 1.5Gb/s to 270Mb/s, old existing cable can be effectively used to transmit HD-SDI signal and, making the users to configure HD video surveillance system with ease.

To use this function, camera side needs DoubleReach™ transmitter of DR101P-TX, and PoC repeater of RP101P can be worked together to extend video transmission distance.

 •  Supports up to 400m HD-SDI video transmission using 5C-HFBT(RG-6) cable
 •  It is effective when the existing cable’s performance is low or its length is over 200m
 •  Can be interfaced with PoC repeater RP101P

DoubleReach^TM doubles HD-SDI transmission distance twice

 Features WEBGATE’s DoubleReach™

     •   Needs DoubleReach Transmitter(DR101P-TX) on the camera’s side
     •   DP101P-TX includes built-in PoC/CoC function. No need for power supply and RS485.
     •   DoubleReach supporting DVR models have built-in DoubleReach Receiver on odd number channel.
        (Channels can be relocated on the split-screen)

Use of DoubleReach™ Transmitter (DR101P-TX)

    •   DR101P-TX has built-in PoC, normally it does not need additional power supply.
    •   But, if the video transmission distance is long, DC24V can be supplied to DR101P-TX separately.

In case of long distance video transmission, additional power input to DoubleReach™ is possible

•  You can only use HD-SDI video transmission and camera control function, without camera power supply function as follows.
