Digital Video Recorders (DVRs)

Digital Video Recorders (DVRs) consist of three main types:

  • PC based Digital Video Recorders are complete hardware/software computer-based systems incorporating video capture, video multiplexing, video (and optionally, audio) recording and playback, video display and remote video access via modem, Internet and/or LAN.
  • Embedded DVRs do not use a Windows™ operating system and contain no software at all on the hard disk(s). All application functions are contained (embedded) in firmware (software encoded on chips).
  • Mobile DVRs are embedded systems meant specifically for use in vehicles. They incorporate anti-shock and anti-vibration mountings and generally have 12V DC power inputs.

Up to a short time ago, PC based systems provided better functions and features for a lower dollar. Recent advancements in technology, however, have allowed us to create and offer a line of embedded DVR systems, the LE Series, that provides all the major functions that most DVR users are looking for – multi security cameras, high quality video, excellent compression, fast viewing and recording speeds, motion detection based recording, scheduled recording and fast remote access of quality live and recorded video. In addition, Sentry embedded DVRs can easily be upgraded to accept from 4 to 8 to 12 CCTV security cameras. And at highly competitive prices!!

Sentry SMD systems are state-of-the-art mobile DVRs with the features of our embedded and PC based DVRs but also with additional features such as vehicle status recording on video (vehicle speed, braking, turn indication etc). Video can be backed up to CD or Hard Disk, accessed and downloaded over a LAN or the Hard Disk can be swapped for another.

Sentry PC based DVRs are not simply a collection of computer hardware, however – they represent carefully selected hardware and software components which are proven to work well together in the demanding video processing environment. Software, hardware and firmware settings are carefully optimized to ensure maximum performance without problems. Sentry PC based DVRs can support multiple numbers of CCTV security cameras – from 4 to 16.

Sentry Security Systems Inc. manufactures all its own PC and Embedded DVRs using Sentry H Series and GV video capture boards for PC based systems. Each DVR is complete except for the monitor.

All Sentry PC based DVRs include Watchdog technology for operating system monitoring and system auto-rebooting if an error is detected. All our PC based DVRs include a partitioned hard disk with all software loaded into a small “C” partition and a large “D” partition for video recording. A bootable recovery CD is provided for the “C” partition using system restore software so in the event of any software corruption, the “C” drive can be recreated in it’s original condition without affecting any recorded video on the “D” drive.

Microsoft Windows™ XP is provided as the operating system on Sentry PC based DVRs. In addition, system restore software is also included on all systems. All software provided includes original CDs and manuals.
