46 Video Multiplexer with Video Motion Detection
APPENDIX B
ALARM RECORDING
CONTROL
Most multiplexer installations require that alarm events be
documented on videotape. The multiplexer provides all of the
necessary connectors and signals to accomplish this and is flexible
enough to satisfy most video documentation requirements.
A multiplexer alarm event begins when the unit detects an alarm
signal at the alarms connector, or motion at a camera set up for
motion alarms. The sequence of events following alarm detection
is determined by one or more of the following:
 Multiplexer option settings.
 VCR programming.
 Connections between the multiplexer and the VCR.
Uncontrolled Alarm Recording
When alarm recording is not controlled, the VCR records alarm
cameras as normal video. Recorder operation is not affected by
alarm events. The VCR simply records alarm video output by the
multiplexer at the set time-lapse speed. Uncontrolled alarm
recording requires only video connections between the multiplexer
and the VCR. Alarm connections at the VCR are not required.
To set up the system for uncontrolled alarm recording:
 Connect the multiplexer vcr in and vcr out connectors to the
VCRs video output and video input respectively.
 Set the multiplexer ALARM DURATION option to the minimum
number of seconds you wish each alarm event to be recorded.
 Set the VCRs time-lapse speed as desired.
 Set both the multiplexer VCR RECORD TIME and VCR ALARM
RECORD TIME options to match the speed set at the VCR.
