Sentry Security Systems Inc. announced the release of the new Sentry SE Series embedded digital video recorders (DVRs). These full-featured SE series DVRs support up to 16 cameras and use dual video stream compression technology to maximize recording quality without sacrificing remote transmission speed. Locally recorded video is compressed using MJPEG compression while video transmitted remotely is compressed using MPEG4 compression. Available with up to 4 hard drives, the Sentry SE Series DVRs manage and recycle video automatically and have the ability to back up video to a USB thumb drive.

Live video on all cameras is always in real-time, 30 frames per second (fps) per camera with recording speeds of up to 120fps (60fps on 4 & 8 port models). 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). The Sentry SE Series DVRs can be accessed remotely over Internet/LAN and support static or dynamic IP addresses; as well various models of PTZ cameras can be controlled, both locally and remotely. Operation can be by IR remote controller (optional), push button or mouse providing a comfortable “feel” for users. 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.

The Sentry SE Series Low Cost Embedded DVRs are full-featured entry level DVRs supporting 4, 8 or 16 camera inputs at very attractive prices. The Sentry SE Series of embedded DVRs combines the stability and tamper-proof reliability of embedded DVRs with the high video quality, fast remote access speed and feature-rich performance of PC based DVRs. Couple these outstanding qualities with exceptional ease-of-use and an industry competitive price and the Sentry SE Series become serious contenders for most DVR applications. The SE Series uses dual video stream compression technologyto allow local video to be compressed for recording by MJPEG compression while video to be transmitted remotely uses MPEG4 compression. This dual compression method provides very high quality local video recordings with faster remote transmission. Video is recorded at Half D1 resolution on 4 and 8 port models, and either Half D1 or CIF resolution (selectable) on 16 port models. All models offer three levels of video quality adjustment (Low, Normal and High).

The Sentry SE Embedded DVRs provide ease-of-use and excellent video quality with real-time display and a recording speed of up to 120fps. Dual stream video compression of MJPEG for local recording and MPEG4 for video transmission are provided for optimum quality, speed and reliability. Operation can be by IR remote controller (comparable to a TV or VCR), push button or mouse, providing a comfortable “feel” for users with or without PC experience. In addition, these DVRs can be accessed remotely over Internet or LAN and various models of PTZ cameras can be controlled through the firmware, both locally and remotely. Both a standard VGA and composite (BNC) video output are provided to connect a local monitor. Both video outputs may be used at the same time offering an excellent solution and no extra cost when a second display monitor is required. VGA connectivity provides optimum video display quality for the lowest cost. Various models of PTZ cameras can be controlled both locally and remotely (using supplied remote client software). The commonly used Pelco D and P protocols are supported.

Using a standard Internet browser or the supplied remote client software, users can perform any local operations from a remotely connected PC, including changes to settings, video search and playback, etc. Live video on all cameras is always realtime – 30 frames per second (fps) per camera. Recording speeds vary by model, from a total 60fps on 4 and 8 port models to a total of 120fps on 16 port models. Recording frame rate is adjustable by camera allowing certain (more critical) cameras to be configured with higher recording frame rates while others (less critical) can be reduced. Video can be recorded automatically, manually, on motion, on alarm or by schedule.
