> Time & date code stored with the
video
> 12 Volt DC operation, with optional
external AC PSU |
Using the latest wavelet video compression techniques, Hindsight has
been designed and developed by Ovation Systems to offer the very best
in digital recording technology. Wavelet compression is significantly
more efficient than the older and more commonly used JPEG standard,
allowing Hindsight to offer extended video record times whilst
maintaining excellent picture quality.
Hindsight's hard disk recording has the advantages of low maintenance
and improved picture quality over traditional analogue tapes together
with the ability to directly record and access alarm events with pre
and post trigger. Hindsight has been designed around dedicated hardware
and records completely stand-alone. It is not the more usual PC card
and software solution, and is therefore highly reliable, ideal for long
term unattended operation in applications such as mobile, covert and
remote surveillance.
Efficient wavelet compression means longer record times
With an 18 GByte drive Hindsight can record over 7 hours of video at
quality comparable to standard VHS machines. With wavelet, VHS quality
video equates to a compression ratio of around 30 to 1, much higher
than JPEG systems. Please refer to the table below showing the
approximate record times at 30 to 1 compression. As may be seen, in
time-lapse mode, several weeks of video may be recorded before disk
overwriting takes place.

Stand-alone reliability
As Hindsight is a dedicated video recorder, the system is small and
highly reliable. This means quick start recording and the ability to
avoid system crashes, ensuring vital "footage" is not lost. This
feature is especially important in mobile, event and long term
unattended recording where reliability is of paramount importance.
Continuous loop recording
Hindsight may be configured to record a continuous loop of video that
is over-written time and time again. This primary loop may be recorded
in real time or time-lapse mode, as the user requires. An internal 4
event timer allows this loop to be started and stopped at given times
of the day, and even changed from real time to time lapse mode, to
ensure the best possible use of the available disk capacity.
Alarm (event ) recording
To compliment the primary loop recording, 4 alarm inputs may be
configured to record events permanently to disk (i.e. record clips on a
separate part of the disk to the primary loop). These events are
recorded in either real time, or in time lapse, with programmable pre
and post trigger. Once collected, the user may recall the events
directly from a list, showing event date and time, negating the need to
search the disk for each event, greatly speeding up the reviewing
operation.

PC control and configuration
software
To view the recordings, Hindsight may be set locally into play mode or
the disk removed and installed into another Hindsight unit for viewing
at a more convenient location. A PC is then connected to Hindsight, via
a serial link, to enable the control of the replay functions and list
all the events that have occurred.
