BTW I mentioned a video sensor near my house... it needs high contrast to trigger it... If I wear dark clothing on a cloudy day... no trigger. Bright clothing on a sunny day, no problem, I have a green by the time I hit the limit line. No light at night... no trigger. Use the bright halogen headlight at night, triggers every time and I roll right through. So it is all a matter of playing the darn things just right, be they loops, hexes or camera.
The "hex ones" are they wider than they are long? If so that's the type I'm actually accustomed to dealing with, if you can get your front wheel on the front line and your rear wheel on the rear line, I usually do this on the left corners and it works like a charm, also if it doesn't trip it and there is traffic (IE don't feel safe legally running the red), you can then tilt your bike down towards it's side so it's about to rest on the ground (leaving your wheels touching at the corners still) which should no matter what trigger the darn thing. Hope this helps and I get your frustration. The cam ones I can't help with as far as I know no intersection I ride through uses them, but I do know they are also around my area as well.
