SECURITY CAMERA SYSTEM UPGRADE AND REPLACEMENT
FOR MONTGOMERY COUNTY DETENTION CENTER
SECURITY CAMERA SYSTEM 17000-42
control devices, supporting a variety of different VCRs and digital
recorders.
2. The network of analog video recorders may be a mix of Resistive Ladder,
RS-232 and IR (Infra Red) devices that are controlled by a singular
Recorder Control CPU unit.
3. The matrix switcher/controller system shall integrate with Network Client
Remote Management Software and a suitably-equipped keyboard, to
directly control important Intellex® digital video management system
functions such as play, stop, pause, record, rewind, and fast-forward.
U. Backup CPU: The matrix design shall provide for the option of a dual CPU/CPU
“hot switch” configuration. In the event that a CPU malfunction is detected, the
“hot switch” must provide an alarm output and automatically transfer control
over to the other CPU to ensure no system downtime due to a single
malfunction.
V. Video Loss:
1. The matrix switcher/controller system shall provide the option for a video
loss detection module for sensing video inputs for video loss detection.
Video loss detection can be set for the following conditions:
a. Off - Video loss detection not enabled
b. Sync - To detect a reduction or loss of the video signal level
c. Low - To detect low picture content
d. Medium - To detect medium picture content
e. High - To detect high picture content
2. This optional feature must be integrated into the video switching bays and
must automatically set the appropriate threshold level for video loss
detection.
3. The matrix switcher/controller system, upon video loss, must provide a
log of changes, and be able to send video loss message to an assigned
alarm monitor or e-mail. The minimum information supplied on the port
shall be date/time of video loss, camera number that lost video, status of
video signal, status of sync, and video loss detection mode.
W. Power:
1. The matrix switcher/controller system must be capable of operating to full
specification from an applied voltage of 120Vac (±10 %) for the
AD2010N and AD2010P, and 100–240Vac (auto-sensing) for the
AD2020N and AD2020P at a frequency of 50-60 Hertz. For switcher
bays, the power consumption cannot exceed 60 watts per bay with all
functions operating.
