WiFi Alarm Home Security System, 120dB Alarm System with Motion Sensor and Remote Control, Alarm Security System for Shed Garage Alarm

works really great. very loud siren, sensitive motion controls and truly remote control operation with our iphones from anywhere in the world - all without subscription.

Purchased for our out building. Even with a little distance from the house it’s still easy to hear. Well worth the price.

I'd rate this five stars except for the absolutely worthless instructions (as several others have noted,) the implication it works on your wifi network, and the app which has nothing to do with this system. It has no relationship with your phone. That's too bad, it would be nice to know if it got triggered in your absence.The only thing wifi about this is that it uses the 2.4mhz wifi frequency to communicate with the various parts. In the package, you get the 120db siren, three motion sensing units, and two key fobs. It's pretty easy to set up, although you are on your own to figure things out.Upon inquiry, the seller claims that in the included 9V batteries in the sensors will last three years. The siren uses 120VAC. I set things up for a friend that has had trouble with a devious, silent intruder in an area of her property. The fobs will work through a bunch of plasterboard and wood timbers without issue. They have a short pullout antenna which surely helps. The fobs even have a slide up/down cover to prevent accidental triggering of the buttons. The very loud siren can be activated with the fob in the event you think someone is there, even though not sensor triggered. If activated by a sensor, it will run for a minute unless you shut it off.If this all sounds right for you, you will not go wrong.

One motion detector quit working within four hours.

Good

Uno de los sensores no enciende, el cable de bateria se despega.

Cheap crap - the speaker seems fine but the app is confusing and the detectors didnt even work

Best alarm system for the money. I have used this system for years on four different locations. With the ease of setting up and the loud alarm, that is all I require in a trip alarm.
