The solution proposed by Crisma Security involves the use of Navtech Radar ClearWay technology which was created specifically for the detection of incidents in real time and in any weather and visibility conditions.
Each Radar sensor is able to monitor a motorway section of about 1 km for both carriageways, guaranteeing with an approximation close to 100% the detection of stationary vehicles, in the wrong direction or pedestrians. Working with microwave technology, it does not suffer from the problems related to visibility.
The Radar detects the GPS coordinates of the vehicles and of the anomaly found and sends an immediate report to the Radio room.
It is also able to control a PTZ camera to also have the visual feedback of the event.
Radar is particularly useful in tunnels, as an accident in a tunnel can cause fires. In these cases the water of the hydrants mixed with the hot fumes create an impenetrable fog that inhibits any sensor. The Radar, on the other hand, is able to provide the position of the vehicles inside the tunnel, the direction of the pedestrians attempting to evacuate and the position of the emergency vehicles.
