Designed specifically for police video surveillance operations, AfterBurner is able to record video in real-time, or in time-lapse, onto DVD write once disks. Once burnt, the disks are viewable on either a PC or standard, low-cost, DVD players.
Alternatively, the system may be used for long-term unattended recording, storing up to 10 DVDs of video to internal disk before burning. The recorder is 12 V DC powered and suitable for battery operation, ideal for covert installations.
AfterBurner time-lapse DVD recorder offers all the benefits of the very latest DVD digital video technology with the versatility of a traditional time-lapse VCR. Operationally, it has been designed in accordance with the UK’s Police Scientific Development Branch Digital Imaging Procedures by producing video evidence on closed, write-once, read-many (WORM) media that cannot be altered. This has the major benefit of allowing the use of standard (VCR tape based) evidential procedures and audit trails.
AfterBurner operates by converting the video input to a digital uncompressed data stream. At this point, on screen display text is added to the video. Video is processed for time-lapse recording in a temporary video buffer before being MPEG-2 encoded and stored on a local hard disk. Recordings are then formatted for capability with standard DVD players and burnt to DVD disk.
Recording to hard-disk allows the re-burn of disks in the event of a power failure or malfunction and to provide duplicates when required. It is also possible to leave the unit unattended for a week or more, collecting data that can be downloaded to DVD at a later date.
