D-Cam speed & red light camera
Digital speed & redlight camera
Truvelo D-Cam describes a family of digital speed and red light cameras that are available with differing speed measurement technologies. All feature Truvelos unique single- photo secondary speed check verification method. All systems also deliver a choice of front or rear photography. For accuracy, versatility and innovation look no further. Various speed measuring technologies available including piezo sensors (D-Cam P) and laser (D-Cam L).
The Truvelo “D-Cam” is a dual capability speed & red light camera which uses a single colour camera for coverage of three lanes of traffic. It is a permanent “automatic unattended” camera, able to provide front or rear photography with a single photo for speed violations in both cases, and a pair of rear photos for red light offences. The same camera can be used at speed only sites or at combined speed/red light sites. Three sub-surface sensors are used for speed measurement and vehicle classification.
Speed & Red Light Sites
The sensors are positioned before the “Stop” line with the secondary check lines beyond the “Stop” line. A 1.8m check line is painted at 750mm beyond the “Stop” line with supplementary lines 18cm either side. The front wheels will fall within the area of the three lines to provide a visual proof of the secondary check. Also, the delay time between the speed measurement and the photo capture is recorded on the image to allow a speed calculation. The “D-Cam” will act as a speed camera during the green and amber phases and for the first second of red time.
The “D-Cam” can store up to 100,000 encrypted and signed images but in reality the images will be transmitted over an ADSL/3G connection in real time to the back-office. Alternatively they can be downloaded on site to a Shuttle PC and returned to the back-office.
The specially designed “Integra-Post” features a combined camera housing to provide greater vandal resistance and a modern streamlined appearance.
The floor of the camera housing acts as a shelf for the camera and lowers to provide easy access to the camera. All the required camera equipment and data storage is contained within the “D-Cam”. There is no roadside cabinet full of vulnerable electronics. A remote auxiliary flash is employed to provide optimum image quality.
Camera lowers for easy access on UK style Integra & Cyclops housings.
