Video Detection System

The Vendor is required to provide video detection system shall be comprised of two major hardware components: a video sensor and a communications interface panel.
- Video sensor
1. Camera and processor
• The camera shall be a color CMOS imaging array.
• The camera shall have HD resolution of at least 720p (1280x720 pixels).
• The camera shall include a minimum 10x optical zoom.
• It shall be possible to zoom the lens as required to satisfy across-the-intersection detection objectives, including stop line and advance detection.
• It shall be possible to zoom the lens remotely from the TMC for temporary traffic surveillance operations or to inspect the cleanliness of the faceplate.
• The camera shall have direct, real-time iris and shutter speed control by the integrated processor.
• Support
• 264 video compression for streaming output.
2. Video sensor enclosure assembly
• The camera and processor shall be housed in a sealed ip-67 enclosure
• The faceplate of the enclosure shall be glass and shall have hydrophilic coating on the exterior surface to reduce debris accumulation and maintenance.
• The faceplate shall have a thermostatically-controlled indium tin oxide (ITO) heater applied directly on the interior surface to keep the faceplate clear of condensation, snow, ice and frost.
• An adjustable aluminum visor shall shield the faceplate from the sun and extraneous light sources.
• An integral aiming sight shall assist in aiming the camera for the detection objectives.
• A removable rear cap and cable strain relief shall seal the power connection.
• The rear cap shall be tethered to the enclosure to avoid dropping the cap during installation.
• The rear cap shall be fastened to the body of the video sensor with a single, captive bolt.
• The rear cap and enclosure shall include gore breathers to equalize internal and external pressure while preventing moisture from entering the camera.
• The sensor shall be self-supporting on manufacturer’s mounting brackets for easier fastening during installation.
3. Power and communications
• Power and communications for the video sensor shall be carried over a single three conductor cable.
• Termination of the three-conductor cable shall be inside the rear cap of the enclosure on a three-position, removable phoenix terminal block.
• Each conductor shall be attached to the phoenix plug via a screw connection.
• The video sensor shall operate normally over an input voltage range of 89 to 265 VAC at 50 or 60 HZ.
• Power consumption shall be no more than 16 watts typical.
• No supplemental surge suppression shall be required outside the cabinet
• All communications to the video sensor shall be broadband-over-power via the same three-conductor cable that powers the unit.
• Coaxial cable shall not be required.
- Communications interface panel
1. Video sensor connection
• A 3-pole terminal block, shall supply power and broadband-over-power communications to 1 or 2 sensors.
• If two sensors are connected on a port they shall be connected in parallel.
• The broadband-over-power communications shall provide a throughput of 70 to 90 mbps.
• The broadband-over-power connection shall support at least 1,000 feet of cabling to the video sensor.
• Each physical sensor port shall include a power switch controlling up to 2 sensors as well as an led indicating status of power delivery on the port.
• There shall be an led for the first four sensors learned into the system to indicate the status of communications.
• The configuration software shall allow the user to see communication status of all sensors connected.
• Each physical sensor port shall contain a resettable fuse.
• Each physical sensor port shall provide high-energy transient protection.
2. Traffic management center (TMC) communications
• The TMC connection shall support 10/100/1000 mbps Ethernet communication.
• The communications interface panel shall proxy all network requests that arrive on the TMC connection to avoid unwanted network traffic from reaching the broadband-over-power network between the communications interface panel and the video sensors.
• All communications to the video detection system through the TMC connection shall be to a single IP address.
• The system shall be able to provide full HD quality video through its wan port for use in streaming video back to the TMC or any remote location.
