Many CCTV facilities are in need of a high performance DVR that can deliver high resolution D1/4CIF video at high frame rates without compromising one over the other. These applications will find the DVR-008S4C to be the right product at the right price. Other important features of this digital video recorder includes expandable storage options, remote network viewing and a sophisticated motion detection system. Ambush also has incorporated a very stable operating system based on linux, so that users will get a smooth balance of perform and stability without encountering a hitch.

Functions :

• Ambush's Embedded Digital Video Recorder adopts a high performance embedded real-time multi-tasking operating system (RTOS) and an embedded CPU, to perfectly implement all the functions needed to build a surveillance system. Running all the software of a FLASH makes the system more steady and reliable.

Compression function:

• Supports 8 channels video in. Each channel can be compressed independently in 25F/S (PAL) or 30F/S (NTSC), using H.264 algorithm.
