SECURITY CAMERA SYSTEM UPGRADE AND REPLACEMENT
FOR MONTGOMERY COUNTY DETENTION CENTER
SECURITY CAMERA SYSTEM 17000-80
18. The complete dome assembly must be capable of operating to full
specification with an applied voltage of 18 to 30Vac at a frequency of 50
or 60Hz and meet Class 2 standards. The power consumption cannot
exceed 11W with all functions operating. The dome assembly shall have
surge protection for the video, communications, power, and alarm
connections.
19. The camera shall have a 22X optical zoom and be a ¼-inch CCD
interline transfer device. The camera shall provide a minimum horizontal
resolution of 470 lines with a usable video signal with a scene
illumination of better than 0.3 Lux (20 IRE with AGC on) and 0.02 Lux
(with an open shutter selection of 1/4 sec).
20. The video output synchronization shall be 2:1 interlace and will observe
the NTSC or PAL standards. Line-lock with an adjustable vertical phase
must also be provided.
21. The lens must be color corrected, 4–88mm, f1.6, and must have
continuous autofocus with manual override. The lens must also have auto-
iris with manual iris override. The autofocus and auto-iris resume settings
shall be configurable via on-screen menu settings.
22. The dome shall incorporate a twist-lock release base for ease of
installation and service. This base enables the installer to wire the
appropriate cables onto an I/O board contained within the twist-lock base.
The I/O base enables wiring to be completed once and for the
housing/eyeball assembly to be connected and disconnected to the twist-
lock base without disturbing the wires or connections. This I/O base
option shall support four alarm inputs and three auxiliary outputs. In the
event that the camera assembly must be replaced, the I/O base shall store
presets, patterns, and other selected programming information. Each base
will include diagnostic LEDs to indicate power and proper
communications to and from the matrix.
23. An installation tool that enables service personnel to connect and
disconnect the housing/eyeball assembly without the use of a ladder or lift
must be available. The dome and base must be available separately so
installation of the base can be accomplished by qualified personnel prior
to the purchase of the dome or housing/eyeball assembly. An outdoor
housing must also be available and shall provide for the same ease of
installation and service.
24. Upon initial power up and after dome resets, diagnostic tests must be run,
including communication loopback, camera loopback, and motor circuit
tests. The results of these tests must be displayable on the monitor. After
initialization, the dome shall automatically pan, tilt, and zoom to its
previous position.
25. The dome shall be SpeedDome
