Hindsight wavelet compression digital hard disk video recording system.

Please Note: This product is now being phased out of production.
Dedicated stand-alone "Black Box" digital re coding system - Not PC based! Highly efficient wavelet compression offering excellent record times and picture quality Real time (50 fields per second) record rate with time-lapse options Continuous loop recording with alarm inputs that permanently store events to disk Removable hard disk for remote viewing Time & date code stored with the video 12 Volt DC operation, with optional external AC PSU.

Extended Record Times

Efficient wavelet compression means extended record times whilst maintaining excellent video quality. With an 18 GByte drive Hindsight can record over 6.5 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, a much better figure than JPEG systems. Please refer to the calculator below showing the approximate record times. As may be seen, in time-lapse mode, potentially several weeks of video may be recorded before disk overwriting takes place.

Standalone 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.

Simultaneous Loop & Alarm (Event) Recording

Hindsight may be configured to record a continuous loop of video that is over-written time and time again. This primary loop (or main ring) may be recorded in real time or time-lapse mode, as the user requires.

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.

Typical Hindsight Disk Allocation

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.
