ZOpid 2-in-1 Motion Detector and Door/Window Contact Sensor Mini Alarm System

excellent. works great. surprised our son when he opened the door.thanks

THIS WAS SO EASY TO INSTALL (A CAVEMAN...ETC). JUST REMEMBER YOUR CODE AND HOPE THAT ANY INTRUDER DOES NOT "JUST" REMOVE THE BATTERIES! TO GAIN ACCESS...DOPES...! THE PRICE WAS RIGHT. THIS WILL KEEP TEENAGERS OUT BUT NOT THE PRO'S!

Bought this to secure a basement door. Seemed to set up well but within 48hrs the set button stopped working. Now it can not be programmed, armed or disarmed. It is simply an eyesore now.

Short review: Device does what it says. Easy to mount on the wall, uses standard batteries and not watch-type button batteries like some similar devices do. Long battery life even with daily use. I use it as a motion detector and it detects motion quickly and goes off loud enough to startle someone. Tip - if you're trying to protect an area and can't afford monitored systems, then mount this on the wall behind where a door opens, that way when someone opens the door and it goes off, when they turn around it might not be so visible than if you place it right inside the door. It will still go off when the door is open and breaks the beam, but is harder to spot and MIGHT scare them off.

Simple, inexpensive little device but does the trick. Put at top of stairs to monitor my clients (who should only be in my office or waiting in foyer). I purposely set it off (...accidentally...)when new clients come so they know the rest of the house is off limits...
