2. Basic Operation
2.1 Live Viewing
One or both monitors may be used for live viewing, with various combinations of full screen images and
multi-screen images displayed on the two monitors (Simplex models always display full screen images in live
mode).
•
Select which monitor you wish to view by pressing “MONITOR A” or “MONITOR B” keys (not applicable to
Simplex models).
•
Press the camera keys identified as “1”, “2”, “3”, “4” etc. to select a full screen image of a camera on the
selected monitor.
•
Press the “PIP”, “QUAD” or “MULT-SCREEN” keys to see multiple cameras images on the selected
monitor (not applicable to Simplex models)
2.2 Recording
When the VCR and multiplexer are both in “RECORD” mode, images from all the cameras will be
continuously recorded onto tape. Irrespective of what is being displayed on the monitors, the system will
always record full screen images onto tape, providing maximum recorded image quality. This is the primary
purpose of a video multiplexer.
•
The multiplexer is normally in RECORD. If the word “PLAY” is displayed on monitor “A”, press the “PLAY”
key momentarily to return to RECORD mode. The VCR is put in record mode by pressing its “REC”
button (refer to VCR’s manual for details).
•
The time lapse mode of the VCR must be set. Typically the 24 hour mode or 27 hour mode is selected
which means that a 180 minute VHS tape will last for a whole 24 hour period (refer to VCR’s manual for
details).
•
If a “VCR Sync” cable is used , the time lapse mode of the multiplexer is set automatically . Otherwise the
time lapse mode of the multiplexer must be set to match that of the VCR (via the Installer menu).
2.3 Playback
Both the VCR and the multiplexer must be in “PLAY” mode in order to play back recordings.
•
To put the multiplexer into PLAY mode, press its PLAY key and keep it pressed for about one second
until the word “PLAY” appears on Monitor “A”.
•
To put the VCR into play mode press its “PLAY” key (refer to VCR’s manual for details).
•
Playback is always on monitor “A” and may optionally be on monitor “B” also (refer to configuration
section)
•
When the system is playing back recorded images, the full screen image from any of the cameras may be
selected.
•
If you wish to see more than one camera image at a time, press the “PIP”, “QUAD” or “MULT-SCREEN”
keys as required.
•
Remember to routinely play back tapes to verify the correct functioning of the whole system.
