FlashBack 1 Introduction The motion detector module is designed to operate with Ovations Systems’ FlashBack 1 or 2 range of flash memory video recorders. The module has advanced features including the capability of selecting motion detection zones within the picture and an optional video and audio pre-event buffer.
3 Quick Start Guide Motion Detector Set-up As standard, the motion detector is set-up to assert the FlashBack record input for at least 5 seconds each time motion in the picture is detected. It is possible to re-configure the unit via buttons and switches beneath the door. See Section 5.
4 Quick Start Guide Motion Detector Zones NB: Zones can only be set-up with a video monitor connected to the “video monitor” output (pin 23 of the D-type). E.g some of the DB25 cable assemblies supplied with FlashBack include a “video monitor” output BNC female connector.
Video Monitor Output Switch The right position, Switches the video monitor output (pin 23 of the D-Type connector) to show the FlashBack video input with the motion detector onscreen display superimposed. This position should be use when setting up the motion detector.
E.g if the FlashBack is set to line level input, all switches should be set to ON. If the Flashback is set to microphone level (ie a certain amount of audio gain in dB) a corresponding level of attenuation needs to be introduced using DIP Switch-2...
With perspective values of 2 or more, the object detection size is the same at the top of the picture but increases towards the bottom of the picture compensating for perspective. Issue: 1.2 Ovation Systems Ltd Page 8 www.ovation.co.uk...
