[b] Provide RJ-45 plug connectors to be used at both the camera and cabinet ends. Category 5e cable, RJ-45 connectors and crimping tool requires approval from Rhythm Engineering. Follow the manufacturer's instructions to insure proper connection of equipment.

[c] Provide 14 AWG three conductor power cable meeting the requirements of IMSA specification 20-1.

[d] Existing vehicle detection at the project intersections must be maintained until the InSync adaptive system is activated.

[e] Mount video camera(s) as directed by the factory-certified representative using mounting brackets to obtain manufacturer recommended installation location. Provide mounting bracket detail to Engineer for approval prior to installation. Connect ethernet cable and power cable in accordance with manufacturer's requirements from each camera back to the controller assembly.

[f] Adjust camera(s) as necessary during the system integration as directed by a Rhythm Engineering representative.

(c) Vehicle detection.

[1] Furnish and install video vehicle detection for all approaches following the manufacturer's specification, in place of standard in-pavement inductance loop detectors, unless otherwise approved, in writing, by the Township Public Works Department and Township Engineer. For video detection, the Autoscope Solo Terra vehicle detection system shall be utilized, meeting the following specifications:

[a] EasyLink connectivity for IP-addressable broadband communications and web server interface for easy setup.

[b] Streaming digital MPEG-4 video output.

[c] Vehicle detection, traffic data measurement, speed, and incident detection.

[d] Integrated color camera, zoom lens, and dual-core processor for advanced image processing.

[e] 22x continuous focus lens.

[f] Image sensor and processor sealed in waterproof and dust-tight NEMA 4 housing with a thermostatically controlled faceplate heater.

[g] EasyLink (broadband communications (up to five Mb/sec) with RJ-45 connection from required terra interface panel (TIP).

[h] Three-year warranty.

[2] The video detection system shall be installed and calibrated in accordance with the manufacturer specifications. PennDOT, the Township Public Works Department, and the Township Engineer must approve the detector layout and operation.

[3] LEDs. All vehicular and pedestrian signal heads shall be LED (light-emitting diode) as manufactured by GE Lumination (formerly GELcore) and shall meet all current ITE specifications and requirements. The modules will carry a five-year manufacturer's replacement warranty for materials and workmanship and light degradation that begins at the date of delivery. If an LED fails, the supplier will provide a new replacement LED. Street signs should be LED per PennDOT standards when applicable.
