No other security environment is more demanding than the mission-critical enterprise arena. If a video system fails, it can mean security operations fail. Such video surveillance systems require unparalleled reliability, scalability and redundancy, coupled with high image quality and intuitive operator control. 

ComVision is proud to introduce the NSR-25. This Network Surveillance Recorder is an enterprise class solution designed specifically for use in high end security applications where quality real time video footage is essential.

Built on distributed client-server architecture, the ComVision NSR-25 is specifically designed for digital recording as part of the ComVision Longreach  Solution.

The ComVision NSR-25 solution enables you to simultaneously view, store, and capture high-quality video and data. Each 16 channel NSR is capable of storing 31 days of real time footage at a resolution of 4 CIF. Users also have the ability of storing video data to a central location across a network on our Remote Storage Server. (Please see NSR-RS16B datasheet)

The NSR-25 has a proven track record. It is installed in some of the world’s most prestigious security installations. These include major Government sites, Infrastructure sites, Town Centers, and Corporate sites.

All ComVision NSR series devices are capable of being distributed across a network. Network-distributed video systems offer substantial economical, installation and performance advantages over classic analog, matrix based systems. The ComVision Virtual Matrix functionality makes setting up operator control points, adding additional monitors, adding and viewing additional cameras a breeze.  

There is no limit to the scalability of the ComVision Longreach Series.

Taking Control:

Control any camera on any NSR unit with ComVision’s DCT Touch Screen Keyboard. This unique keyboard can be setup anywhere on the network; it allows users to switch any camera to any monitor and gives full proportional Pan/Tilt/Zoom control.
