BASIC OPERATION WITH VCRS
VCR Recording
There are two modes for recording, synchronous or asynchronous. For optimum tape
recording and playback, the multiplexer must be configured correctly (see
Rec Time on
page 34).
Synchronous Mode
Time Lapse VCRs must be used in this mode. The VCR generates a trigger signal (SW)
which must be connected to the multiplexer. The recording will be perfectly
synchronized with the VCR fields.
Asynchronous Mode
Either a Time Lapse VCR or normal VCR can be used in this mode. The recording time
must be set to the same speed as the VCR: Real Time, 6 hr., 8 hr., 12 hr., 18 hr., 24 hr., 27
hr., 30 hr., 40 hr., 48 hr., 72 hr., 168hr, 240 hr., 480 hr., 720 hr. or 960 hr.
VCR Playback
To review a previously recorded tape, the Video Output connector of the VCR must be
connected to the multiplexer’s VCR IN connector (either BNC or SVHS). Decoding of
recorded tapes consists of automatically separating the multiplexed camera fields and
then grouping each camera’s fields together for display. Using the coded data that
was inserted into each recorded field, the unit can automatically reconstruct each
camera’s ID, status, date, and time information. The images can be displayed in any
multi-windows format on the Main monitor, just like in live camera mode. Moreover,
the user can enable or disable the OSD (on-screen display) of the recorded date, time
and alarm information.
Cue the tape to the desired event, play the tape, and assign the cameras you desire to
view from the tape to windows in the view, switching those windows to VCR mode
using the
Live/VCR button.
