IBM Compatible PC-based Digital Video Recording Surveillance System for colour or monochrome Video Cameras, Record and Display Live Images or Playback simultaneously.

Four Channel Motion Detection Video Recording.

Multiple Masking Zones for each channel.

Adjustable Detection Sensitivity for each channel.

Using Motion Detection images are recorded only when changes are detected.

Audible Warnings, custom Sound Files associated with each channel may be configured to automatically play when image changes are detected.

Eliminates tedious and time consuming review of tape recordings, labelling and storage of tapes.

Eliminates the high cost of a Time Lapse VCR, Maintenance and Cassettes.

Considerably Higher-Resolution, Lower-Noise, Deterioration-Free and Consistent Image Quality than possible with a Quad and VHS or even SUPER-VHS VCR.

Operates continuously: no down-time while tape rewinds or is changed.

CAPTURE CARD:

Single Chip Bt878 BrookTree IC Video Capture, PCI 2.1 compliant.
Compatible with CCIR/PAL (Australia) EIA/NTSC (Read this) (USA) & SECAM (France) TV systems.
4 standard composite video (AV) 75 ohm inputs via RCA sockets.

Each Video input can be configured with it's own Brightness, Contrast, Sensitivity, Video Quality (Compression), Mask Area(s) and Camera ID.

Camera ID with Full Date & Time Stamp: Day / Month / Year / Hour / Minutes / Seconds / AM-PM may be recorded with each channel.

Motion Detection Mode with variable sensitivity, sequentially monitors images for changes and records video to AVI file.

Eliminates tedious and unproductive visual monitoring, system may be configured to play a standard or custom audio file associated with each camera when motion is detected. User's attention to activity in areas under surveillance may be announced by PC Sound System ie: "Movement at Rear of Building" - "Movement in Display Area" - etc - etc.

Zoom In / Out, Fast Forward and Random access to any position in file, Full-Screen playback of any channel using Windows Media Player.

Masking allows user to define areas that will be disregarded by Motion Detection function, multiple masked areas may be defined anywhere on image or the entire image masked and segments of importance unmasked.

The AVI recording file for each channel may be located on different HDDs, the maximum file size that can be replayed with MS Media Player is ~ 500 megabytes, for larger files specialised third party software (if available) will be required.

Capture Rate: 3 ~ 5 images per second per channel, depends on PC Hardware, number of channels in use, image content, compression, other running tasks, etc.

Full-Screen replay using Media Player.

Control system with Mouse or Keyboard.

Images can be saved as a BMP or JPEG file.

Print images.

AVI, BMP and JPEG files may be easily copied and distributed to Police, Security Personnel, etc, via Floppy Disc, CD ROM, Zip, Tape, e-mail, etc,.

AVI, BMP and JPEG files can be viewed with Windows Media Player, MS Paint, Quick View, etc, no special software required.

Sequential capture and motion detection analysis of images from 4 inputs at up to 384 x 288 (CCIR/PAL Australia & SECAM France/Russia) 320 x 240 (Read this) (EIA/NTSC USA/Japan).

* LOWER-NOISE
* HIGHER-RESOLUTION see comparison below
* DETERIORATION-FREE
* CONSISTENT IMAGE QUALITY

Compared to conventional 4 Channel Quad / VCR recording systems that are susceptible to fluctuating results depending on condition of Tape, VCR Heads and Transport mechanisms.

GoVideo-DVR4: CCIR/PAL recording 384 (H) x 288 (V) per camera = 110 592 pixels.

Quad & VHS VCR: CCIR/PAL recording ~ 160 x ~ 288 per camera = 46 080 pixels, 58% less data.

Quad & SUPER-VHS VCR: CCIR/PAL recording ~ 265 x ~ 288 per camera = 76 320 pixels, 31% less data.

Above comparison is based on a VCR operating in Frame-Recording mode, as most VCRs (in Time-Lapse mode) only record Fields, the situation is considerably worse as only 144 (not 288) horizontal scan lines are recorded per camera. In Field mode per camera pixels for VHS are: 23 040, 79% less data, for Super-VHS 38 160, 65% less data.

SYSTEM REQUIREMENTS:

CPU: Pentium 200 or above, Pentium 500 or better recommended, Celeron not recommended.
Motherboard: PCI 2.1 compliant.
OS: Microsoft Windows 95/98 with latest updates.
One PCI Slot and unshared IRQ (Interrupt Request).
Sound Card: (optional) to play audio warning(s) initiated by motion detection.
Hard Disk space: Plenty of disk storage for recording, at least 1GB per camera.
System RAM: 64 MB or above.
Display card: 16-bit high colour or 24-bit true colour, 800 x 600 or above, Direct Draw compatible.
Video Cameras: Up to 4 with standard 75 ohm composite video output, monochrome or colour, reliable recording is not possible with a mix of monochrome & colour cameras.

STORAGE REQUIREMENTS:

Following example is from GoVideo-4 system, the details relating to storage are in general also applicable to GoVideo-DVR4. GoVideo-DVR4 records one AVI file for each channel, not multiple files for each event.

Hard Disk Space requirements are impossible to specify, there are numerous variables that will affect the size of each AVI Video Clip, they include: Image Resolution - Compression - Capture Rate (Frames-per-Second) - PC Speed/Performance - Image Content:- A solitary person moving about (only a portion of image is changing) - VERSUS - Numerous persons and/or vehicles moving about (large portions of image are changing).

Below are examples from a system that operates continuously 24 hours per day, PC hardware is: AMD K6-2/450 CPU (approximately equal to a 450 MHz Pentium), Epox MVP3 Apollo AGP/PCI ChipSet Motherboard with 1 MB L2 cache, 128 MB 100 MHz DRAM, IDE 33 ATA HDD.

This data is for a single channel operating in Motion Detection Mode, Camera is a 600 + H-Line Colour Day / Night / IR unit with Automatic Iris Lens and Infra-Red illumination, the scene is the driveway / entrance to our warehouse. Activity in this situation includes: one to several persons moving about in the driveway, motor vehicles coming and going and passing motor vehicles, a person moving about in the driveway occupies 60% ~ 20% of the captured image frame height, a Truck occupies up to ~ 40% of image area. Motion Detection Sensitivity level is such that a Cat moving about at an ~ 6 metre wide point in the scene triggers recording Day or Night (under InfraRed illumination). GoVideo settings are: Resolution = 384 x 288, Compression = 5 (minimum compression, therefore highest image quality), Frame Rate is set to maximum for this Computer, 62 per 10 seconds.

There are 5 levels of Compression, with a static scene and resolution = 384 x 288, frame file size varies between 1 kB ~ 7 kB as compression is varied from 1 (maximum) to 5 (minimum). The minimum Frame Rate is 1 per 10 seconds, the maximum rate is dependent on PC Speed/Performance and resolution. AVI file data (number of frames) was obtained using MS Media Player with Indeo video 5.04 Decompression Filter - Video Renderer.

Over a 20 day period 3 547 events were captured, they occupied 467 MB of Disk Space, the smallest AVI file was 12 kB (2 Frames), the maximum was 8 389 kB (896 Frames).

Examples of some files: 14 kB (2 frames), 56 kB (12 frames), 163 kB (38 frames), 294 kB (59 frames), 66 kB (104 frames), 722 kB (137 frames). There is no direct relationship between the number of frames and file size, this is variable and depends on frame to frame changes in the images.

Above data is from an actual operating system and is presented as a guide only, actual results in each situation will vary considerably because of the numerous variables involved.
