Linux-based DVR

July 2003 CCTV, Surveillance & Remote Monitoring

"The Linux-based DVR, a new technology which challenges traditional Windows- and PC-based DVRs, currently widely used in South Africa, is set to change the way the security industry views video recording," says Anthony Rosenbaum, MD of CMT Trading - sole distributor for CS Lilin, a manufacturer of security technology products.

The Linux System adopts system-on-chip technology, storing the Linux operating system on chip, DOM (disk on module), retaining system integrity even if the hard disk is damaged or has crashed. Additionally, the system applies one processing chip per camera to produce the best possible picture quality in both split and full screen display.

Intelligent motion detection can be configured for each channel, maximising disk efficiency by ignoring periods of non-activity. The data search function provides quick image search and easy playback. The Linux DVR also integrates network compatibility; the digital images can be transmitted via a LAN and viewed by a Web browser without additional software. Remote monitoring and control are no different than operation on the system itself.

Multiple choices of data backup of recorded images and sequences on floppy, CD-RW, USB-ZIP or via the network; saving data on another computer. This backup data can be replayed on any machine by most Web browsers without the need for additional software. Some additional key features are MPEG 4 Compression technology, maximum recording speed of 100 frames/s (PAL), Triplex (record, view and play at the same time).
