Local connections to a laptop computer must facilitate routine repairs, diagnostics, and all other operational functions. In addition to the standard communication ports required for operation, provide, at a minimum, the following interfaces to the PCCTV: USB port, Ethernet port and serial port. Provide a wireless communications interface, field-hardened for long-term freeway deployment where it is typically subject to wide daily and seasonal temperature swings, wind gusts and typical road vibrations with an extended operating temperature range from -30F to + 165F. Coordinate wireless communications interface type and configuration with the Representative for network compatibility. The wireless carrier data account will be provided by the Department. Provide the wireless communications interface as a unit detachable from the PCCTV assembly to facilitate easy change out to other communications means.

assembly and communications equipment . Using solar array, supply the nominal operating voltage to the CCTV camera assembly and communications equipment. Provide solar array that consists of photovoltaic, single crystal silicon modules. Provide automatic recharging of power supply batteries to normal operating levels with meters showing charge. Securely mount the solar array to the PCCTV for operation and transport. Provide mounting capable of swiveling, tilting, and reangling the cells to optimize exposure to solar rays. Include capability to lock the solar panels at any angle necessary to optimize solar exposure. Provide AC/DC battery charger. Provide battery bank that at full charge can power the camera assembly at continuous use for 8 hours without recharging from the solar array. Equip battery bank with a battery controller to prevent overcharging and over -discharging. Provide battery controller with external battery level indicator. Protect the battery, controller, and power panel from the elements and vandalism. Provide battery subsystem with automatic recharging of power supply batteries. Equip battery subsystem with meter to indicate if batteries are being charged or used. Provide battery bank consisting of low-maintenance, gel batteries. Contain the battery in a NEMA -rated compartment or enclosure that prevents water ingress during operation or transport. Fabricate the compartment to completely contain any spills from damaged or malfunctioning batteries. Provide battery enclosure that is separate from enclosure to house PCCTV controller.

lockable window at the main frame of the PCCTV, to allow the use of power feed from an alternate power

source such as a generator set on trailer, or road -side power outlet. Provide a selector switch inside the window that connects the internal loads of the PCCTV to the battery-powered subsystem, or the above AC- to-DC power converter. Include provision for the external AC power to charge the batteries when the PCCTV operates using the external AC power. Provide AC -to-DC power converter that converts 120 volts alternating current ( VAC) power to DC power suitable for operating the P CCTV. Protect all data and electrical connections from the PCCTV using transient voltage surge suppression (TVSS) equipment. Provide window with a grommet-lined semi-circular notch at the bottom to allow passage of extension cord with the window closed. Provide twist locking type receptacle. Provide an extension cord with male plugs at both ends that is suitable for outdoor uses, oil resistant, minimum 50 feet long, and equipped with three 12 AWG conductors. Provide cord where one of the plugs is regular type and the other plug is suitable for use with twist locking type receptacle. Deliver cord to location identified by the Representative.

a grounding conductor to the PCCTV assembly. Provide deliberate grounding connection from the trailer frame to this grounding terminal. Provide grounding terminal suitable for terminating a wire of up to 2 AWG. Provide painted signage next to the grounding terminal, with 1 -inch tall black letters on white background, stating “PROVIDE GROUNDING TERMINATION HERE.”

resistant coating. Equip trailer with tie-down points to facilitate storage and transport by securing the trailer to a utility trailer or flatbed truck. Equip trailer with class-A taillights, using a plug adaptor. Furnish trailer that can be set up at the site with its own chassis and outriggers, without being hitched to a vehicle. Equip trailer with fenders over the tires that are made from heavy-duty material sufficient to allow a person to stand and operate or perform maintenance on the unit. Delineate the trailers on a permanent basis by affixing retroreflective material in a continuous line on the face of the trailer as seen by oncoming road users. Finish trailer with a glossy federal safety aliphatic acrylic urethane finish. Provide orange color to conform to the MUTCD requirements for portable changeable message signs (PCMS). Provide a trailer mounting structure for t he Camera housing, mounting bracket and peripherals (camera assembly). Provide accessible mechanism to easily raise and lower the assembly. Provide a locking device to lock the camera assembly in the raised or lowered position. Provide a single metal telescoping mast pole to mount the camera assembly that is an integral piece of the body of the trailer. Provide support capable of adjusting the height of the camera assembly and allows the camera assembly to rotate 360 degrees around the vertical axis of the support beam, without requiring more than a single operator to perform height or angle adjustments. Provide capability to elevate the center-point of the camera assembly to a minimum height of 20 feet. The locking mechanisms must prevent the camera assembly from changing angles during windy trailer with a hitch for connection to a towing vehicle. Provide hitch with a towing capacity of 5,000 pounds. All trailer hitch components must conform to SAE J684 Standards for Class II trailers. Equip hitch with a 1/4-inch safety chain for secure attachment to towing vehicle. Provide trailer with sealed, flush-mounted, combination stop, tail and turn lights, and front and rear sided marker lights. Provide a rear license plate display holder, and a rear center identification light bar for illuminating the trailer license plate. Provide a rear fender. Provide four hydraulically or mechanically adjustable outrigger leveling pads permanently installed at each of the four corners of the sign trailer for leveling and support functions. Provide leveling pads with a minimum capacity of 2,000 pounds each. Provide leveling pads that are adjustable using a single operator, and without any special tools. The leveling pads must be capable of lifting the trailer, so the tires do not touch the ground. Equip trailer with tires according to ST225/75R15 Load Range C. Provide 5-lug pattern wheel configuration. Affix the manufacturer’s name and the trailer make and model to trailer. Provide an operator’s manual within the control enclosure of each unit. Equip the PCCTV trailer with a metallic enclosure to house the wireless communications interface. Provide a weatherproof and rust resistant enclosure securely fastened to the trailer structure. Equip the enclosure with a door with a key locking mechanism, and provisions for externally locking the door using a typical pad lock.

1211.3CONSTRUCTION—As shown on the Standard Drawings and as follows:

a camera assembly and related communications enclosure that are comprised of single continuous runs without splices. Make provisions to keep some slack in the vertical cable run within or around the telescoping pole. Provide strain-relief mechanism to the cable.

area free of debris so a maintainer can access the unit and be protected from most vehicular traffic. Configure all outriggers to equally support the weight of the trailer and ensure the unit is completely level.
