multiple masked areas may be defined anywhere on image or the entire image
masked and segments of importance unmasked.

VCR: CCIR/PAL recording ~ 265 x ~ 288 per camera = 76 320 pixels, 31% less
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.

also applicable to GoVideo-DVR4. GoVideo-DVR4 records one AVI file for each
Camera, 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 Camera 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
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
