Combined speed and red light enforcement

136 Traffex 2011 sees the world launch of the 143 Truvelo 'D-Cam L', a dual-capability speed and red light camera. The versatile device may be used as a speed camera alone, or be deployed at a red light intersection where it will monitor red light offences and act as a speed camera on the green and amber phases. It digitally signs, encrypts and stores two images for a red light offence and one image for a speed offence.

Up to four laser sensors are permanently mounted in the D-Cam L's roadside housing, along with the camera itself.

There is no roadside computer cabinet required as the D-Cam L contains all the necessary image capture and transmission modules onboard. Images are transmitted to the Truvelo Back-Office Server (TBOS) by ADSL or 3G/HSDPA. One TBOS can handle up to 30 cameras.
