Question: Is this unit weather resistant? Can it be used on an outdoor gate?
Document: Again, this works like advertised. The adhesive backing is very sticky. Even on decorative trim partial contact was strong. I'm white doors you don't even notice the unit. Doors need to be shut for the system to be able to arm. The wireless signal from the sensors, to the unit, to the server, to my iPhone is very responsive.
Well...I guess two bad contact sensors out of 6 is only a third...One sensor showed up as a Key FOB? The other displayed low battery and after replacement of the 2032 it displayed the same.I had ordered an extra 2 contact closures so I was fine and returned the damaged units.
This was as simple to add to my existing iSmartAlarm system as I had hoped that it would be. Great product!
The sensor works perfectly however with the conflicting information on the page I was expecting 2 sensors.... So I am a bit disappointed about that. Functionally it's great, I would give it 5 stars.
Sensor works as advertised, integrated just fine with system. Will probably add a few more in the future. Would recommend.
It was advertised as a two pack of sensors. What was delivered was a singe sensor. When I contacted the company they said &#34;oops - that was wrong - bad luck&#34;. No offer to fulfill the promised/advertised order. To cap it off most of the batteries were dead - and the cheap plastic cases are almost impossible to unscrew and fix.
I really like having a system that I can turn on and off by the internet. It is one of the better off the shelf security systems I've seen.
I ordered this thinking I was getting only ONE sensor  for $29 and though tthat was a little steep, but I needed it. I bought these and found out there are TWO full sensors included! So at roughly $15 per sensor, this is a great deal and I highly recommend if you have the ismart alarm!
Amazon is very bad about describing quantities. A question was asked on April 14, 2014 how many did you get and 8 out of 9 said they received a box of two. Needing 10 - I ordered 5, but today I got just 5, each wrapped in a plastic bag (no boxes of two) The customer service people were no help at all. Now I will have to spend another $150 to complete my system. Had I known this I might have bought something else.
Answer: no
