Field of View
1. How far can a motion sensor detect?
D203B can detect up to distances of 8- 10M.
2. Do PIR sensors work in the dark?
Yes, motion sensors work in the dark. The way that a motion sensor detects movement has nothing to do with how light or dark it is in the immediate area. ... Since infrared energy is present and can be detected regardless of the amount of light in the environment, a PIR motion sensor will work just fine in the dark.
