Video Cassette Recorders (VCRs)
In the MAXPRO-Net system, VCRs can be commissioned in a variety of ways:
•
Fixed - Connects (in series) between the video output channel (after the text inserter)
and the video monitor. It can record whatever is displayed on that monitor and can
only playback onto that monitor.
•
Dynamic - A video output channel is connected to the "video in" and the "video out"
is connected back to the video input matrix. The VCR can record any camera that
can be displayed and controlled from any monitor.
•
Dedicated - A video camera is passed through a pre-text inserter module (overlaying
camera description, time/date) and then directly to a dedicated VCR machine. The
"video out" of the VCR connects to the VCR-REVIEW video input matrix.
3.8.4.1 Direct VCR Control
A standard relay output module can be used to provide activation of eight VCR functions
(stop, play, rewind, fast-forward, pause, slow, record and eject) as individual contact
closures. An interface card would be fitted to the VCR machine.
