Details: Pentium™ 4 processor, 256MB RAM, 120GB 7200rpm hard disk, DVD-RW/CD-RW drive, 10/100 LAN adapter, keyboard, mouse and H Series video capture board(s) (see below). The DVR is contained in a medium tower case. Windows™ XP is provided as the operating system; Sentry H Series and system restore software are included.
Recording Time: The 120GB hard drive will typically hold about 3 weeks of recordings, when using motion detection recording, HM (MPEG4 like) compression and 320x240 resolution.
Sentry H120-8 - 8 camera, 120fps, one H-120-8 capture board. Point-of-Sale
Third-party electronic POS systems may now be integrated into H series DVRs via the AVE VSI - an external device that transmits POS transaction data to the DVR. Click here for more information on POS integration.
Excellent Image Quality
H Series boards and software provide excellent image display and recording quality through proprietary drivers and compression codec. Video can be displayed and recorded at 320x240, 640x240 or a true 640x480 non-interlaced resolution which eliminates the 'ghost effect' in motion video seen with many other systems at 640x480.
Multiple Camera Resolutions on same Screen
Some security cameras can be displayed at different video resolutions on the same screen, allowing optimal video display and recording, yet minimizing recording file size.
High Compression Ratio with High Video Quality
Video is compressed for recording by MJPEG or HM (MPEG4-like) compression: HM is proprietary compression technology, designed specifically for CCTV applications. It provides high video quality and yet saves a great deal of disk space through superior compression. CPU acceleration instructions also help the system gain real-time performance.
Multiple Recording Methods
Video can be recorded continuously at maximum speed, continuously with Smart Saving, On Motion, On Alarm, by time-lapse or by schedule. Different cameras can have recording methods set independently.
Multi-Drive Concurrent Recording
Different security cameras can be specified to record into different logical or physical drives, so that some camera recordings can be kept for longer periods than others. This is particularly useful where some camera recordings may be more critical than others.
Smart Saving during Recording
The recording frame rate varies according to the amount of movement. Low frame rates are used for more static video and higher frame rates for full motion video. The more motion detected, the faster the recording fame rate.
Advanced Motion Detection and Tracking
Moving targets are automatically detected and tracked by a tracking block. The H Series is sensitive to moving targets in bad lighting environments, and not sensitive to camera shake and the auto-panning of PTZ security cameras.
Noise Tolerance Feature
A motion detection noise tolerance feature reduces false alarms and unwanted recordings caused by weather changes (rain, wind, lightening etc.), and light changes. The sensitivity of noise tolerance can be adjusted for each camera.
Security and Stability
Four levels of ID and password protection are provided and an audit log of “log on and off” sessions, configuration changes and more is kept. The SmartFile management feature prevents disk fragmentation and increases system stability. Video recordings are saved in a database, optimizing storage utilization. What's more, H Series DVRs have a hardware watchdog that restarts the system automatically in case of system errors.
Powerful Remote Control
The H Series DVRs use a client/server architecture. Multiple clients can simultaneously monitor/control the same DVR site through the Internet, LAN or direct dial-up connection. Remote Viewer allows monitoring/recording of up to 16 remote cameras, remote control of PTZ security cameras, and remote configuration of multiple DVR sites. Remote Record Player downloads and replays video recordings from remote DVRs. Up to 16 cameras from different DVRs can be viewed at one remote site.
Search recording log files by date, time, single camera or all security cameras. Also search by recording type – motion detection, smart saving, alarm input or time lapse. Play back in quad, 9 or 16 camera displays and switch to single camera full screen (and back again) with a mouse click. Speed up to 16X or slow down to 1/8 speed. Increment backwards and forwards by one frame.
CCTV devices can be integrated into the H Series. Through an RS485/RS232 converter, PTZ cameras can be remote controlled for panning, tilting, and zooming. Via I/O ports or an I/O box (depending on board model), the capture board can receive signals from traditional sensor devices to start recording. Motion based recording can be used to trigger external devices such as lights, switchers, gates, and other traditional alarm devices.
H Series DVRs instantly send out notifications when there is an abnormal situation or intrusion. There are many ways to notify an event:
1. Send a voice message to a desk phone or a cell phone through optional modem.
2. Send a text message to a fax or an e-mail address through optional modem.
3. Sound an event alarm.
4. Flash an event message on the split screen.
5. Display the event camera in full screen.
6. Trigger traditional alarm devices.
7. Send event reports daily, weekly or monthly by email.
Exporting the video as 'evidence' is simple and easy. A single mouse click snaps the current video frame and saves it to an image file for print out with location, date and time information. Another mouse click records the video to an AVI or self-executable file. The self-executable file is embedded with watermarking and password protection. The self-executable files created can be viewed on Windows™ 98, ME, 2000, and XP systems without any special player required.
File Recovery on System Power Loss
An automatic file rebuild occurs after any unexpected power loss or software shutdown, limiting video loss to less than 3 seconds.
