LR-DS-9000HFI-S Hybrid series nvr 

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      LR-DS-9000HFI-S. This Network Video 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 LR-DS-9000HFI-S is specifically designed for digital recording as part of the ComVision Longreach  Solution.

The LR-DS-9000HFI-S series NVR uses next generation Hybrid technology. These Hybrid Network Video Recorders are real-time machines capable of simultaneous recording and playback at genuine 4CIF resolution on every channel. Additionally, the Hybrid unit is capable of recording 1.3 Mega Pixel and 2 Mega Pixel IP cameras.

The Comvision Hybrid NVR allows users to connect up to 24 video and audio channels. These cameras can be a mixture of analogue cameras, IP cameras, IP encoders and Mega Pixel cameras.

The Comvision Longreach Solution 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 NVR and IP camera 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.
