AUTO SIGN OFF
System operators can be given different levels of selection and control privilege. If an
operator of higher priority forgets to sign off the keyboard, the system can automatically
sign them off after a period of (1
operators of a lower priority.

REMOTE CONTROL OF CAMERA PTZs, VCRs, ETC.
Almost any video input source connected to the MAXPRO-Net video system can be
configured to be controlled directly from a keyboard.
Before controlling a video input source (camera PTZs or VCRs), the video input source
concerned must first be displayed onto the monitor that the keyboard is currently
selecting.
All control command functions made from the keyboard will be directed exclusively to
that video input source. The MAXPRO-Net system manages this automatically.
2.14.1
Camera PTZs
Several types of camera PTZ interfaces are possible:
1. Direct relay control using an output module in one of the I/O subracks, giving control
of pan/tilt and lens functions,
2. Two-wire data communications to a variable speed pan/tilt site receiver, for
controlling AC and DC pan/tilt units and lens control at variable speeds,
3. Fixed speed,
4. Variable speed,
5. High speed PTZs / Domes,
6. RS-485 of third party PTZ/Dome equipment.
2.14.2
VCR Control
The MAXPRO-Net system has been designed to simplify the operation of not just camera
PTZ equipment, but all other associated video equipment.
In a system that utilizes Video Cassette Recorders (VCRs), the basic functions (stop,
play, rewind, fast-forward, slow, pause, record and eject) of the VCR machines can be
extended to the keyboards.
An output control module is placed in a slot of an I/O subrack and allocated as a control
output for one particular VCR machine. By using separate output control modules, many
VCRs can be configured into the one video system and controlled from any keyboard.
By using a peripheral control module (PCI), up to eight VCRs can be controlled using
infrared, resistive-array or RS-232 interface to each machine.
