Digital Video Recorders (DVRs) consist of three main types, plus a mobile series:
- 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, Covet embedded DVRs can easily be upgraded to accept from 4 to 8 to 12 CCTV security cameras. And at highly competitive prices!!
Mobile DVR Applications
Covet 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. These rugged mobile DVR’s are easy to use, provide excellent MPEG4 video and the GV series provides GPS information.
PC Based DVR’s
Covet 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. Covet PC based DVRs can support multiple numbers of CCTV security cameras – from 4 to 16.
All Covet 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 Covet PC based DVRs. In addition, system restore software is also included on all systems. All software provided includes original CDs and manuals.
Central Surveillance by Center V2
Center V2 allows up to 20 GV DVRs to be remotely monitored. Each Center V2 remote system can display up to 320 channels of live video can be displayed in pages of 24 channels per page. Up to 500 Center V2 systems can be served by one Dispatch Server, so that Center V2 will support a video Central Monitoring Station.
Remote System Monitoring
By using the CCS (Control Center Server) 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 CCS system. Up to 99 DVRs and up to 500 cameras can be monitored by one Control Center concurrently.
Dynamic DNS Support
A Dynamic DNS service is offered by GeoVision to all V6.0 and later users. This service provides an easy-to-remember domain to fast locate your DVR with a changed dynamic IP address, by constantly updating the IP address of your DVR to the DNS server. Domain name registration is done in the DDNS application.
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.
A choice of Geo H.264, H.264 V2, Geo MPEG4 ASP compression for local recording is selectable by camera (Geo MPEG4 gives about 4 times the compression of Wavelet).
Camera images can be displayed and recorded in a choice of 720×480, 720×240, 640×480, 640×240 or 320×240 pixels. All cameras images must run at the same resolution although this can be changed at any time.
New Webcam Multi-Function Remote
More useful functions for management of multiple servers (DVRs) is provided through a web-interfaced Webcam application.
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, time and date.
Digital watermarking can be selected, to prove the integrity of recorded videos. This is particularly useful if recordings are to be used as evidence in court.
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).
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.
All can be turned on or off with just one mouse click. Compression of transmitted images can be set from remote systems as H.264, independent of recording compression of the host system. H.264 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.
Alarm and Email functions
The (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.
Smartphone Remote Access
iPhone, Blackberry and Android smartphones are supported
