Fox Outdoor Sabre Motion Sensing Alarm

Have 3 of these for a couple years now, very simple to use and work well. Very loud and batteries last me about a year. They detect at about 15 feet, so they’re good for typical room entrances.

Someone often jump over my fence in the middle of night. Doing what? In order to get close enough to my neighbour’s mobile phone for implant the malicious code in smart phone. For what? Stealing password of online banking. It is become so populous now doing this for thief(so called hacker) . I tried all of ways by installing two ip cameras focus at place this guy standing. No use, why? Because ip camera is so easy to hack and controlled by thief. For example, thief can use radio to disable the motion detection of ip camera. Finally, I get this alarm from Amazon. It is controlled by code. It means thief no way to disarm this device unless he know the code. Simply enough. Now what? No more jump over fence at mid night. It is solved by 30 bucks device . Now thief parking the car in the front of my neighbour house. I know they change the way to doing same thing. It is not my business now. It is purely public security. I have informed neighbours about this. However, nobody can stop this.

This is excellent, so loud, easy set up and great price. Definitely recommend

Easy to install. I need to read the directions each time I set it for the correct sequence of operations. If you set it often, you might likely remember the instructions. Could be a little louder. It is a high pitched, shrieking, irritating sound but could be a little louder.

Good
