D-Cop is a digital camera intended for Speed, Red Light and Stop line enforcement.
The D-cop comprises of a head unit installed on a pole approximately 3 meters high. No Base cabinet is needed.
The head unit houses a primary 5.0 Megapixel video camera, an ancillary 1.3 Megapixel video camera for video recording, a computer, interface electronics, a primary evidence mass storage device, uninterruptible power supply, a lamp monitoring unit and a communications interface. Traffic violations are automatically detected by using radar or loops. All the D-cop elements, inside the head-housing unit, are in a modular configuration with each unit fitted with its own cooling fan.
All interconnections from the street equipment are brought inside the head unit.
D-cop is made from aluminum and the head unit has a hinged lockable back and a glass opening for the camera, the flash and the radar detector. Fan assisted cooling is provided plus a temperature sensor to ensure that the unit does not operate outside its specified temperature range.
The Camera Module
The camera module mounts a 5.0 Megapixel video camera with a resolution of 2.590 x 2.048 pixels. Such camera sensor is big enough to monitor contemporarily 4 lanes of traffic.
Ancillary Video Camera
As an option the D-cop may install an ancillary 1.3 Megapixel video camera for recording a 15 seconds video clip anytime a violation occurred. The video clip is recorded in addition to the pictures captured by the 5.0 Megapixel camera.
The video clip records a video footage of the road intersection 7.5 seconds before the violation to occur and 7.5 seconds after the violation has been detected.
The flash is installed in the D-cop cabinet or in alternative on an additional pole (side flash) and it’s designed to provide up to two variable power white light flashes in quick succession. The power of the flash is variable to meet the wide range of lighting conditions likely to be encountered. The flash is power supplied at 12 volts and it’s capable to illuminate contemporarily 4 lanes lanes of traffic.
Local Mass Storage Device
The internal Hard Disk works as a mass storage device which stores up to 500 GB of data. Storage requirements are approximately 3 MB per violation, which means that the D-cop can hold over 250.000 violations.
To capture the violations, D-cop uses either radar or loops.
Violations are transmitted to Copland, which is the D-cop Instation software, either on demand or automatically at any time desired.
Access to the D-cop can be achieved via Internet, wireless LAN, WAN or any other communication link, since the D-cop uses a standard TCP/IP protocol.
The purpose of data protection is that D-cop violations cannot be tampered by anyone. The D-cop uses the same encryption methods, used by all major financial institutions (128 bit encryption coding).
Encryption transforms the images into random data ensuring that the nature of the data in unrecognizable to unauthorized observes, rendering impossible to alter any part of the images.
