N.J. Specification No. EB-CCTV-COLOR
Effective Date: July 1, 2001
New Jersey Department of Transportation Specifications for a remotely controlled color closed
circuit television camera assembly.
The purpose of these specifications is to describe the minimum acceptable design and
operating requirements for this equipment.
GENERAL - I
1-1
Components
The Color CCTV system shall include the camera, zoom lens, environmental enclosure,
PTZ mounting, control receiver junction box, and all miscellaneous hardware and
incidental components required to deliver a fully operational sub-system. The mounting
standard is not included in the assembly described in this specification.
1-2
Environment
All CCTV components, while housed in their associated environmental enclosures, shall
operate in the ambient temperature range of -40 °F to +131 °F and shall meet NEMA 4
weatherproof standards.
1-3
Testing
All units shall be subject to factory and prototype testing as described in Section VIII of
this specification.
1-4
Mounting
The Color CCTV assembly shall be mounted as described in this specification. The
supplier shall provide all incidental components, mounting brackets, and cabling
required to achieve a fully functional assembly as illustrated in the contract drawings
and in conformance with NJDOT standards.
1-5
Equipment Compatibility
In order to insure compatibility between the components, the camera, environmental
enclosure, zoom lens, PTZ mounting, and Receiver Junction Box electronics, must all
be integrated by an experienced video system engineering firm. The firm must have
delivered at least one hundred (100) outdoor CCTV assemblies comparable to that
1 of 13
Revision
EB-CCTV-COLOR
required by this document.
The integrator must have at least five (5) full time factory-trained and certified
technicians and/or engineers who are rated for the components to be utilized. The
video supplier shall be able to provide on-site service anywhere in New Jersey within
eight hours notice. The video supplier shall accept full warranty responsibility and
regular support service for the complete CCTV package.
1-6
Electrical Power
All CCTV components must operate on standard 120 volts AC electrical service. The
equipment shall operate over a voltage range of 105 to 125 volts AC at 60 hertz.
Maximum power requirements for the entire assembly must not exceed 1000 watts.
1-7
Options
The Color CCTV assemblies shall operate in two basic configurations. The first
configuration shall connect the CCTV assembly to a Central Site or Video Collection
Node (VCN) via a fiber-optic modem. This modem shall transmit full motion video to the
receiver in one direction and shall pass control data and return PTZ status in both
directions. The second configuration shall return slow-scan video over a dial-up phone
connection.
The CCTV assembly shall be able to support both types of operation. However, neither
the fiber-optic modem nor slow-scan unit are defined in this specification. Space
provisions must be made for either type of communication unit, utilizing typical
components, in the Camera Junction Box described in this specification.
COLOR CCTV CAMERA - II
2-1
Basic Configuration
The CCTV camera shall be a 1/2 inch or 1/3 inch format CCD (Interline transfer
Charged Coupled Device) which has been designed to require no preventive
maintenance or adjustments. The CCD shall be blemish-free. The CCD shall be
designed to minimize or eliminate transfer smear and insure acceptable operation
during minimal lighting conditions. The camera shall be capable of unattended,
continuous 24 hour per day operation in an outside plant environment.
The camera shall be fully integrated with the zoom lens described under Section III of
this specification. The camera shall accept standard C or CS zoom or fixed lenses and
shall be equipped with an auto-iris lens connector compatible with the zoom lens
supplied. The unit shall produce NTSC compatible video utilizing a 1 volt Peak to Peak
composite and S-VHS Y/C output. The camera must be fully compliant with all aspects
of the NTSC specification.
2-2
Resolution and Sensitivity
2 of 13
Revision
EB-CCTV-COLOR
At least 460 horizontal TVL lines must be produced by the camera. At least 786
horizontal and 494 vertical active pixels must be produced by the assembly.
The night sensitivity of the camera is a key concern in that the unit may have to operate
in areas with no primary lighting system. Usable video (80% Peak to Peak Video
Output Signal) shall be obtainable with a scene illumination of 0.1 lux.
Full video shall be obtainable at 4 lux. Both lux measurements are based on an f/1.4
lens with a 75% highlight reflectance measured at the camera face plate.
