SensorSwitch Ceiling Motion Sensor, Passive Infrared PIR Occupancy Sensor, 360° Small Motion Detection, Indoor Use, Low Voltage, Standard Range

Works well east to set up

I recently installed the CMR9 sensor as part of my home security system, and I'm blown away by its performance! Not only does it look sleek and modern, but it's also incredibly effective at detecting even the slightest movements.The sensor's compact design makes it easy to place discreetly in any room, and its wireless connectivity ensures seamless integration with my existing security setup.But what really impresses me is the CMR9's accuracy and reliability. It consistently picks up movement without false alarms, giving me peace of mind knowing my home is secure.Overall, I'm thoroughly satisfied with the CMR9 sensor. Its combination of sleek design, ease of use, and top-notch performance makes it an excellent addition to any home security system.Highly recommended!

This is a good device from a legitimate electrical company from what I can tell.Install is easy. No polarity so it's painless.The programming is not the easiest thing in the world but it's not hard, you just have to understand the blinking light concept and pay attention to the pauses and blinks. It's a little confusing at first.The only thing I needed to program was the delay even though you can program a lot with this. It took me 3 days to program the delay. I googled. I YouTubed. Could not get my setting to stick. It was driving me nuts. I finally resigned myself to look at the directions for the 20th time and looked at the other settings. Voila.Here is the trick (the manufacturer should add this to the instructions as STEP ONE):In order for the delay to work, the first thing you MUST DO is change the minimum time on setting. Mine was set to 15 minutes by default. Who knew?So.. BEFORE YOU PROGRAM THE DELAY, go into the minimum on mode and change it to something LESS than the delay you want to use. I made mine ZERO because my delay is 30 seconds.After I changed the Minimum time on setting, my delay worked perfectly. No way a 30 second delay is going to work if the minimum time on is 15 minutes!Also, this is a 360 degree sensor. I wanted to limit the sensor so when I was in the bathroom, the sensor (in the master closet without a door) wouldn't activate and would only turn on as I walked into the closet.Simple solution: put a little electrical tape over the sensor as necessary to shield the motion. Works great. Use white electrical tape for 2 extra style points.After I figured out the position of the tape and knew it worked, I designed and 3D printed a little hood that I glued on. Looks factory and works perfectly every time I step in the same spot. I almost think they should include something like this in the box as it's kind of necessary in many instances.

Used to control garage ceiling light. Easy install, didn’t mess with programming, goes on , on default 10 minutes, then goes off.

I needed a ceiling mounted sensor (my ceiling is 9') that would detect or my dogs from 20' away. The configuration settings offered the flexibility I needed.

Wiring diagram is misleading. Caused me to wire incorrectly and burn out sensor. Looked up how to wire correctly on You Tube.

Product just as decried and shipped fast

i ordered the first one and the lights never switched off, and had the same problem with the second one. Amazon needs to package this better not in a envelope
