Hoping someone here has some experience with some good high quality door alarm sensors. I know some work at greater distances than others and these will be installed at a lit of locations. I'll need to purchase up to 150 of these things, so cheap is good, but high quality and zero falseing is more important.
I'm off to do some searching, but any help would be awesome. Secondly if anyone knows of a good outdoor sensor to work across chain link gates and such that too would be welcome.
