Time-Lapse DVD Recorder

User Guide

1 Introduction

Designed specifically for video surveillance operations, AfterBurner is able to record video in

real-time, or in time-lapse, onto DVD-R write once disks. Once burnt, the disks are viewable

on either a PC or standard, low-cost, DVD players.

AfterBurner may be configured for video quality and record rate via its front panel LCD

display or serial interface. It is able to record 2 to 3 hours of high quality real-time video per

DVD, which may be extended to 24 hours (or more) in time-lapse mode.

When deployed, the system records to an internal hard disk buffer. As soon as 4.7 GB of

data is available (1 DVD), AfterBurner automatically starts burning the recorded video to

DVD. Once complete, a new blank disk may be inserted ready for the next download.

Alternatively, the system may be used for long-term unattended recording, storing up to 16

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 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.
