The OmniBase is a digital video surveillance recorder for use in security and
surveillance applications in locations such as offices, retail outlets, factories
and car parks. Due to its compact size the product can be used in mobile
applications including police operations, truck and container monitoring and
civil and military marine and aviation installations.
The OmniBase has four component parts namely monitor, recorder,
multiplexer and video switcher integrated into one compact unit. The
OmniBase differs from conventional Timelapse VCR recording systems in
that it records digitally onto hard disk. Once the hard disk is fully recorded
it automatically overwrites in a loop, deleting the oldest images first. The
unit can be configured to record for standard 12 / 24 / 48 / 72 / 168 / 480 /
960 hour periods or programmed to record at a fixed update rate e.g. 4
images per second.
The OmniBase uses the industry standard JPEG image compression to save
hard disk space. Essentially the image is divided into blocks and each block
is analysed and compressed. Blocks with no fine detail compress well (such
as areas of sky or smooth walls) whereas blocks with fine detail take up
more space.
The OmniBase also includes a motion format mode close to the industry
MPEG standard. Essentially only areas of the image that change from
picture to picture are stored. This is sometimes referred to as conditional
refresh. If there is no motion - for example the camera is viewing an empty
room, virtually no disk space is used up during recording.
The OmniBase will power up in the same recording state as it was in, on
power down. This means that in the event of a power cut, the unit will
resume recording when power is resupplied if it had been recording prior to
the power failure.
All OmniBase recordings are watermarked. If they are copied with no
modification onto other recording media the watermark remains intact. If
the file is corrupted, modified, or tampered with in any way the watermark is
destroyed. The watermark type is known as a ‘fragile watermark’ as it is
destroyed by any modification of the archive file. The integrity of the
watermark can be checked using a watermark checking program and a valid
watermark indicates that the recorded file has not been altered in any way
during a transmission or copy process.
