KERUI PIR Motion Alarm with Remote Wireless 433MHz Infrared Motion Sensor Detector Alarm/Doorbell Two Modes SOS for Elders Home

Arrived fast. Works well. Super loud. But remote is confusing. Not the same as shown in video. You just have to try it again and again until you get it to work properly.

Package received quickly. Perfect

After testing, the SOS button works best. The disarm function also works well. The arm button seems to have a slow response. It takes a few minutes after connecting to power for it to respond well. I couldn’t find a wireless USB charging product, so I chose this one because it has a remote control and good reviews. It’s good that it’s small in size, but I wish there was a USB charging product instead of a battery product. The sound seems appropriate. If thieves break in at night, I think this sound should be enough to wake them up. Since it’s for indoor security, USB power shouldn’t matter. I guess there are products that only use USB charging when fishing. I’ll use this for indoor use and if needed for outdoor use, I’ll buy a USB charging product. I prefer wireless~~~^^: I don’t need to install it when I’m not at home. The battery hasn’t been used yet, so I’m not sure how long it lasts.

I opened it, inserted the included batteries, turned it on, and it’s currently working great.

Works very well. Remote control. Two functions.
