Loud 135db Keypad Motion Sensor Alarm Siren for Garage, Shed. Portable Cordless Battery Operated Travel PIR Motion Detector Alert. Freestanding Indoor Infrared Home Security Intruder Burglar Alarm

Great portable alarm. I use it in my camper. This particular model is getting hard to find.

Awesome,! Really Loud and really works to frighten intruders! Has Three Loud keypad motion sensor

Works as advertised

Works great just what I needed to protect my house.

It works good ,however I wish it was immediate alarm. Instead it gives 1 beep for warning then 30 seconds later it goes off.

Supper is loud

Very poor quality. The quality is laughable! It says you can plug it into a power supply, but the place the wire goes is under the back cover. After you plug it in there the back cover doesn't doesn't fit over it! There also isn't a hole in the back cover to run the wire through it. It also says it has red and blue flashing lights when the alarm sounds, but, no it doesn't have any lights. The instructions are written in very poor English too. Buy something else.

There are lots of ethically challenged people in my neighborhood who are really good at evading the police and cameras and getting into my house somehow so I've been through a lot of motion detectors. This one can't be turned off easily. You have to punch a code that you select and program or unscrew the battery compartment. You can program it to flash different colors when it goes off, which is cool. It's not wireless so it can't be hacked.
