Pelco Manual C672M (2/01) 41
SYNCHRONOUS RECORDING
Several camera images can be mixed together through a camera switcher and then
recorded separately onto several VCRs. To do so, assign a camera to each VCR. The VCR
records only the camera assigned to it. This allows recording without gaps.
If you have three VCRs, the video signals from the three cameras can be recorded
separately by connecting the switcher as shown in Figure 6.
The recording mode must be set to L18H, L24H, L30H, or L40H. Table F shows the
suitable numbers of VCRs and cameras.
