DVR Security system – V800 series

DVR Security system - V800 series
General Information

Three models of Sentry V600 Digital Video Recorders and three models of high speed Sentry V800 DVRs are offered, based on GV-600 and GV-800 video capture boards. The Sentry V604 and V804 have 4 camera ports, The Sentry V608 and V808 have 8 camera ports and the Sentry V616 and V816 support up to 16 security cameras. All Sentry V600 and V800 series DVRs have the same software but the Sentry V600 DVRs display and record at a total of 30fps while the Sentry V800 DVRs display and record at a total 120fps. All have the same excellent remote communication capabilities. The high display and recording rate of the SentryV800 series DVRs is particularly useful for critical situations where not even fast movements can afford to be missed.

All DVRs have a partitioned hard drive with software loaded in a small partition. The balance of the disk is used for recording. A recovery disk is made of the software partition and supplied with the system. The recovery CD is self booting and can be used to re-install the total software environment, if necessary, without affecting any recorded video. Symantec Systemworks is included for software recovery. Original CDs and manuals of all included software are provided.

Key Features

Video Compression
A choice of Geo MPEG4, MPEG4 or Wavelet compression for local recording is selectable by camera (Geo MPEG4 gives about 4 times the compression of Wavelet).

Video Resolution
Video pixel resolution of 640×480, 640×240 or 320×240 per camera image is selectable and changeable at any time for display and recording but all security cameras must be the same.

Individual Camera Adjustment
Brightness, contrast, hue and saturation are all adjustable for each individual camera.

PTZ Camera Support
Various models of PTZ cameras can be controlled through the software, both locally and remotely, using the GV-PT/NET add-on adapter.

Multiple Display Options
Live video can be displayed in single camera or various multi-camera modes. Multi-camera display can be immediately switched to single camera by one mouse click on the desired camera image (and back again by mouse click).

Live Display and Recording
Concurrent recording of live video and playback of recorded video is supported.

Recording Choices
Recording is selectable by camera as continuous or “on motion”. Motion detection is performed by the software and sensitivity can be set. A schedule of recording can be set by camera, by time and date.

Mask Function
Areas for “motion ignore” can be masked per camera image. Multiple mask areas per image are allowed.

Recording Playback
The log files of recorded video clips can be sorted and accessed by year/date/time. Video recordings can be played back while current recording is taking place, although recording speeds may slow down. Recordings can be zoomed in/out and moved around the viewing area, on playback. Recordings can be played back at normal speeds, higher speeds, slower speeds or frame by frame. Recordings can be played back by individual camera or all security cameras at a time. Switching from multi-camera to single-camera playback is as simple as clicking on a particular camera window while playback is operational. Additional editing features are provided for single frame image sharpening, exporting, adjusting brightness/contrast and printing. Video clips can be exported as .avi files, playable in Microsoft Media Player or similar. Individual frames can be exported in many file formats, including .jpg\’s. Exported video clips can have the date, time and camera name stamped on the video in a choice of colors

Smart Recording
“Smart Recording” can be selected, by camera to maximize recording speed. Smart recording shares the full recording speed only between those security cameras actually recording at any one time.

Digital Watermarking
Digital watermarking can be selected, to prove integrity of recorded videos. This is particularly useful if recordings are to be used as evidence in court.

Alarm and Email functions
The software can be set to dial out to a remote telephone/cell/pager number on alarm (motion detected) or to send an email with snapshot. Alarm signal inputs and outputs for up to 16 devices can be connected using the GV-I/O adapter.

Audio Recording
One channel of audio can be recorded with any GV-600 series DVR and up to four channels can be recorded with any GV-800 series DVR. Recorded audio can be played back, channel by channel, in synch. with a single camera video playback.

Video Exporting
Video clips can be exported in .avi format, with time and date stamp and played in Windows media player. Single frames can be enhanced for brightness, contrast and sharpness and exported in various graphic formats, or printed directly from the GV software.

Communications
Remote communication is supported by dial-up server, web-cam server, TCP/IP server and multicast server. All can be turned on or off with just one mouse click. Compression of transmitted images can be set from remote systems as MPEG4 or JPEG, independent of recording compression of the host system. MPEG4 will provide much faster transmission.
New Webcam software allows up to 16 cameras to be viewed on one screen from the same or multiple DVRs. Remote communications with Windowsў CE equipped PDAs are now supported with the GV software.

Remote System Monitoring
By using the Geocenter communications feature, the video from recording cameras can be sent to a remote system for display and/or recording. The remote system is designated the Geocenter system. Up to 10 DVRs and up to 80 cameras can be monitored by one Geocenter, concurrently.

Remote System Recording/Accessing
Remote security systems can record locally with Internet or client software and host recordings can be accessed remotely by the client software.
