IS335 WIRED PIR Motion Detector, 40' x 56' (1) OPEN BOX

Replacement for an old sensor. No more false detections.

In these days of smart home automation, some of the wireless solutions don't meet the standards of the solid centurions of their wired predecessors. This device is one of the oldie-but-goodies. Not only reliable, easy to install, no batteries to change, looks good and all of that but will technically out-perform the wireless variety. Don't believe me? Check the instructions on the wireless offerings--actually read it--and you'll find that many will only trigger/report once every 3 minutes "to conserve batttery life". Motion detectors are devices that need to report every time a suspect moves into the area of protection. That isn't protection, its amusement known as Security Theater. Stick with wired tech whenever possible for lower cost, longer life and reliable performance. This is one of those devices.

Easy installation and works like original

Pour remplacer mon vieux détecteur de 30 ans , fonctionne bien .

I have a 25+ year old Brinks/ now ADT house security system. One night motion was detected by one of the three sensors in the house. I finally noticed that the light on the one sensor didn’t come on when approached. I replaced it with this sensor and it corrected the problem. Easy to replace and wire. I then bought two more in case any others wear out. I’ve only had it in a few weeks but is working well. Excellent replacement and quick delivery.
