The Compact NVR-AS 3000 from IndigoVision is a Linux-based standalone device that can record and play back 20 MPEG-4 and H.264 video and audio streams simultaneously with a choice of a 500MB or 1TB removable disk. The unit uses the latest hard drive technology from Seagate. Designed for smaller installations such as retail outlets and commercial premises, the NVR is able to withstand temperature ranges of 0-60°C — making it ideal for installation outside of traditional equipment rooms.
