Bridge the old and new

CCTV Handbook 2012 Products

The Dahua DH-DVR1604-T-4H boasts 16 channel analogue video inputs with full D1 recording as well as 4 channel IP video inputs with 1080P @ H.264 or 720P @ MPEG4. All 16 analogue channels can record at the maximum D1 resolution, or they can be scaled down to CIF, 2CIF or QCIF.

With H.264 compression on video recordings and G.711 compression on audio recordings, this hybrid provides top video and audio quality. It comes standard with a 1TB SATA hard drive, which can be enhanced with the addition of up to eight hard drives (or six hard drives and a CD/DVD-RW writer) should business owners want to record for longer periods before the DVR starts re-writing over older recordings.

Viewing of live or recorded footage is a breeze owing to the DVR’s spot monitor output which has composite BNC, VGA and HDMI output for the main display monitor, and can playback 1, 4, 8, 9, 16 and 20 channels. Back-ups can be done using any USB backup device, including memory sticks, external DVD writers, external hard drives or external CD writers. Additional backups can be made to an eSATA device, built-in SATA burner or they can be downloaded via the network.

The Dahua DH-DVR1604-T-4H can be linked up to speed domes for 3D intelligent positioning. Also, as a result of its network software and built-in Web server, the standalone hybrid offers multi-DVR client, MSS (mobile surveillance software for smart phone) and CMS. It is also packed with intelligent functions such as motion, camera blank and video loss detection. Privacy masking may be applied to each camera with four self-defined, four-sided zones to block out unwanted areas.
