TYCO SAFETY PRODUCTS DSC LC100PI DIGITAL PIR DETECTOR WITH PET IMMUNITY,

Great price, quite a number of user settable options in this. There's no mounting bracket and not even any holes to bring the wires out, but that's easy enough to fix with a drill. There's a large open area for your wires and that's perfect for mounting holes and wire access.

For $10, hard to argue with! I put a couple in my basement as it was short and easy to wire to the alarm control panel.

These are cheap but seem to work well. I actually had to purchase a few replacements for some that I installed a few years ago. They just stopped working. I'm replacing with the same model because they are small and cheap but there may be some long term reliability issues.

We got a small dog last and year and needed to replace our current unit with one that's immune to pets. This one does a good job detecting humans and ignoring a 20 pound dog. The sensitivity is somewhat hart to adjust since you have to put the lens back on to test it and ours is mounted high on the wall; but you only have to do it once.

These are cost effective interior wired motion detectors . They simply do the job that you expect. i purchased 4; I am very satisfied with the performances of these motion sensors.

Only 10 ft range at best.I had to buy another one with a longer range.

This motion detector works great...It took some time getting it set just the way I wanted but it works well now. I didnt but it for the pet friendly setting and instead have it on the most sensitive setting

The original box for the product was terrible but the content was still good
