ALPriority, Laser Interceptor and V1 vs Rear Facing Vitronic PoliscanSpeed

[winterbrew]

Here's one I found in my dashcam archives, after thinking about the results in the first vid ;



Laser Interceptor Quad (2 front, 2 rear), 8.9 heads, v 8.12A firmware misses a rear shot from a Vitronic PoliscanSpeed in the grey cabinet on the left of the freeway. LI was running at maximum sensitivity, and this was a case of failure to detect in time, not failure to jam. V1 picks up the rear laser and alerts after passing the camera.

About 80 -90% of the time, it will detect a rear facer (a miss is rare), but it kicks in around 50 -60m past the camera, which is too late, as the Poliscan has started it's calcs from 10m (33') past the camera, then IPT with a very narrow beam diameter, and will nab you at about 20 - 30m past. Hopefully LI will come up with a way to go to 'Volume 11' on the sensitivity for Poliscan, or give us new compact heads with more than 2 receiving diodes per head.
