Aldridge Traffic Controllers distributes the TrafiCAM Vehicle Detector sensor as an "in-ground" induction loop replacement for vehicle detection used in modern Urban Traffic Control (UTC) systems.
The TrafiCAM sensor is an all in one camera sensor with video processing unit that is suited for all-weather applications and wide operating temperature range suited to hot countries such as Australia and Asian Countries. The camera operates in day or night and can sense direction of vehicles as well.
The TrafiCAM can be configured with a laptop to "overlay" configurable detection zones for each lane of traffic being monitored as shown below:

The setup process also configures output contacts via an interface board mounted inside ATC's cabinet that is interfaced to the External Interface Module present in all SCATS™ compliant traffic signal controllers.
The volt-free contacts essentially report the presence of vehicles which the controller uses to create a demand and adds to the vehicle count reported back the SCATS™ UTC system. Access to the programming and monitor interface is available within the controller cabinet - no need to get up a mast arm to connect to the TrafiCAM with a laptop. The link is via an RS-485 cable over twisted shielded pair cable that is commonly available.
The TrafiCAM is available in both a Narrow angle and a Wide angle version depending on the application.

The camera's volt free optically coupled clean contact outputs are available in 1TI, 4TI or 9 TI configurations where each zone is linked to one of those output contacts to interface to Traffic Signal Controllers or other logging or activating equipment. Each channel also has a local channel LED to indicate state on the Interface Module.
