Chapter 5 — Operation 29
To view what has been recorded, place the VCR in the play
mode and press the tape button on the multiplexer. When
the multiplexer detects the encoded video signal, it starts tape
playback and displays all recorded cameras in the multicamera
format. To view one camera in the full screen format, press
the corresponding camera button. To view multiple cameras,
press the appropriate format button (PIP, 2x2, 3x3 or 4x4).
Cameras may be displayed in any order in any of the available
views.
The multiplexer detects recorded alarm events during tape
playback by monitoring the VIS information returned from
tape. Each field of recorded video is encoded with alarm status
information, camera number, camera title, time and date. The
multiplexer uses this information to identify camera related
alarm events.
When the multiplexer detects an alarm event on tape, it
displays that camera image overlaid with an alarm message.
Recorded alarms do not interfere with the detection of
mechanical alarms, so the multiplexer can process both types
of alarm event at the same time. The front panel LEDs blink
for cameras with recorded alarms, but not for live motion or
mechanical alarms. Live alarm images only display on the
call monitor since the main monitor is used for tape playback.
See Recorded Alarms for details.
Tape Playback With Two
VCRs
Tape mode allows you to view previously recorded video from
the first VCR. It does not affect camera video output to the
second VCR for recording. Recording of camera video at the
multiplexer vcr out connector is a completely independent
operation. This allows full duplex operation with two VCRs
connected to the multiplexer. Without this capability, camera
video recording must stop while a previously recorded tape
is viewed. See Simultaneous Record and Play for details.
Tape Preview
To view what is being sent to the VCR, place the VCR in any
mode other than playback and press the tape button on the
multiplexer. The live and tape lights indicate that the
multiplexer is displaying encoded video — full screen camera
pictures sequenced in camera number order at the rate set on
the VCR RECORD TIME menu.
