NineLeafWireless PIR Motion Sensor Detector Security Alarm Chime, Welcome Doorbell, Mailbox Alert, Motion Sensor Doorbell with Night Light for Shop Store Business Office Home Front Door Entry

I set this up in the kitchen (downstairs rear of the house) and use it overnight to wake me when my dog is pacing around needing to go out. It works very well with the alarm box upstairs in a front bedroom. When I switch the sensor on I wait until I hear the alarm sound upstairs. On occasions this has taken a short while (upto a minute) but so far it has never failed. The sound is loud enough to wake me and it is the best £23 I have spent. Definitely recommend.

Have always used a door sensor for my shop door, but the wind is a pain, so thought I'd give this a shot. Plus points: easy to set up, loud enough, portable, door/wind does not set it off. Minus points: only one ,if people walk around the door area it will go off, but with the receiver sitting within arms reach I can temporarily turn it on and off with it's easy switch. Too early to talk about the battery life, but a few months in and no sign of weakness.

I use this to let me know when my dog is wandering around in the night. It's very useful, and loud and bright. Not very robust, but it shouldn't get a lot of wear and tear. The sound effects are mostly awful, but there are a few that are all right.

We got this to leave by our backdoor when it is open during some building work meaning anyone can walk around the house (normally this is not possible).It certainly does the job and the number of different sounds it emits is amazing - most will become highly annoying as they go on too long but it is a triumph in the art of rubbish melodies - it's all there from Big Ben to Titanic by way of various Umpah bands and Grade 1 piano tunes !!EDITGood fun, irritating but recommended ;)EDIT: I've just bought another set of these so that SWMBO can have a receiver on her SOHO desk. It was a different brand but looked identical however I was disappointed when it did not seem to be paired with the first transmitter. A quick look at the manual though and a few button presses and hey presto it is now working !FWIW, the new model came with rechargeable batteries so that might suit some people although you don't get the choice of using standard AA/AAA's

Easy to use different volume levels

Mounted on the porch and garden doors. Now we know, when our cat is come back to house from his daily trips 🤪Even when is dark outside.Perfect! Recommend!

Although the description includes "Garage Driveway Alarm " the actual instructions say you must not install it outdoors.

The sensor is not working anymore but the ring device still works, we replaced the batteries with new ones many times but the sensor still doesn’t work, is it possible if you could send us a new sensor?
