I am going to contradict Zmax! I do not think that halogen light you have in front is going to work.
Have tried all kind of lights also the type you have and nothing worked well before I got the Par type lamp. I wasted so much time and money on lamps because I had a hard time finding the right lamp. Even thought the whole system was useless.
All the problems went away with the right lamp.
That said I think ZMax is right your carpet might be to reflective
I use 50 W over the sensor and 65 W for the cams.

You have reflections from the ceiling which might trigger the sensor mat? But it might just be like par2pro says that you need a little time to get used to hitting in restricted space.
