Hello everyone, I've been looking at getting outdoor beams (the PIR type) for intruder detection. I've narrowed down my options to basically these two:
Optex BX-80
https://www.idsprotect.co.za/za/en/...-detectors/862-01-bx-80nc-optex-bx80-detector
Optex BXS-AM
https://www.idsprotect.co.za/za/en/...tors/862-01-bxs-am-optex-bxs-wired-detectors1
Both have a long narrow 24m detection range (12m to each side, none to the front). The only real difference seems to be the BXS-AM has anti-masking.
It seems like it would be easy to simply walk up to the BX-80 (while the alarm is armed) and block either the upper or lower sensors and thereby rendering the detector useless. Anti-masking is supposed to detect such masking attempts and set off the alarm.
But our security guys tells me beams with anti-masking tends to give lots of false alarms in their experience. Especially if dust starts to settle on the lenses.
Does anyone here have beams with anti-masking? Whats your experience been like with regards to false alarms?
