Hello
I purchased a unit a short time ago that is used to detect cars coming
into my driveway , I think it works on IR motion sensing , it does let me
know if a car or person comes down my driveway , the bad part is that the
thing gives me so many false alarms , seems to be the most problem after the
sun comes out very bright , I guess my question is in two parts , I cracked
the detection unit open and found the detector , am wondering exactly how it
does it thing and could I locate it in another container that is shielded
better , also wonder if anyone has built or used one of the magnetic
detectors that appear to be based on the metal detector principal , I hate
to dig up and put a 6 ft. diameter loop in my driveway , as an old HAM
operator , I have built a lot of IC projects and at $200.00 for commercial
unit , I might just try , any comments would be appreciated.
