(This estimation is based on a sampling of one hundred 20 MB files each
containing 444 ~ 555 images). By comparison the image capacity of a VCR
with 3 hour tape is just 540 000 images (50 fields per second x 3 600
second x 3 hours).

Quad & VHS VCR:
CCIR/PAL recording ~ 160 x ~ 288 per camera = 46 080 pixels, 58% less
Quad & SUPER-VHS
VCR: CCIR/PAL recording ~ 265 x ~ 288 per camera = 76 320 pixels, 31% less
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.

Hard Disk Space
requirements are impossible to specify, there are numerous variables that
will affect the size of each 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).
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),

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.
