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.
