These wireless door/window magnetic sensors are used to protect the opening of both doors and windows. If a burglar opens the protected door or window, a magnetic switch inside the sensor, will trip, which sets off the security system. Install one at every entrance to make sure your home is protected. Each sensor is supervised (self-checking) for professional reliability and offers you choice in design and performance. It will work with most standard security system which is using 433MHz receiver.LED Indicator: Pull out the antenna of the magnetic detector: When the door or window is opened from the closed position, LED 1 will turn to red for 2 seconds, the magnetic detector will be triggered and will send alarming signal to the main unit. Indication of low battery: When the voltage of battery is less than 7.5V, LED 2 will straightly turn on red light. At this time, you need to replace a new battery immediately.Specification: Power Requirements: DC=12V-8.4V (23A DC=12V Battery Included) Current Consumption: less than 20uA; less than 15mA while transmitting Transmit Frequency: 433MHz Transmit Duration: less than 1s Transmit Distance from host: more than 80m (no obstacle) Installation: less than 15mm between part A and part B Coding Type: Fixed Code Dimension (LWH): 71x36x15mm Operating Temp: -10 ~ +40 centi degree Humidity: less than 90% Shell Color: WhitePackage Included: 8x Magnet Sensor 8x Battery 8x Double-sided Stickers

Garage fail after a couple months
This sensors are complete garbage. I bought 16 of them. After 2 months of using them 4 of them where not working anymore. Some where stuck on the red light and other would just not turn on anymore. I tried with different batteries and would not work. After 11 months only 3 where working. And now all of them have fail. I want a refund.With this sensors you cant trust that your house or business is safe.

Works perfectly w/ my security system; quality was good
Wasn’t sure about these after reading bad reviews, but after getting them I have to say the quality was as good as most others I’ve seen & was fine, dbl stick tape held very well, none were missing or broken, & they all worked. Makes me wonder about those reviews. I see nothing at all wrong w/ these. I like the antenna for doors/windows farthest from the base unit to be sure of a strong connection. Tested them w/ my security alarm system to make sure they would trigger the base unit’s alarm, & that the base unit recognized them & would make the calls to police, myself, & others I chose to be notified in an alarm situation. Went as smoothly as if they were made by the same company as my security system & were meant to go together. Adding them to my system went seamlessly & worked perfectly. I would recommend these.

no battery, only "open" -- no "close" event
Did not come with a battery, only sends an "OPEN" event -- you can't know when the door is closed back again or whether it is safe to arm the system. Meh.

Its performance
It works quite well, though it looks very simple it’s very strong performing, I have not idea about how far can its signal reaches the host but I have many of them installed on the second floor in my hiuse very far from the host and they work perfect.

Worked great for our purposes.
Ordered for the magnets. Added extra magnet to each window so we could get fresh air while still arming our security system.

Bad adhesive.
They work but the adhesive is horrible. They will fall off, setting off your alarm.

No pull tab so batteries are dead on arrival.
All the batteries were dead but one when they got here! It took awhile to figure out that that was the problem. Super annoying but they do appear to work and connected easily to my alarm system...when I bought new batteries...
