The sleek modern design combined with the technical features packed in the sensor makes it really unique. It is a single sensor which can track sort or window open close through the pairing magnet and the same can also detect motion clearly from up to 12-15 feet. Not only that it has an elegant led light built in which you can turn in by pressing at the bottom. Blends perfectly well with door and window frame and can be glued or screwed in. The same device can be put on the wall as a motion detector. Unlike other brands which has different units for motion detector vs for window monitor the nest detect can be used as both interchangeably.

Best system i have had works great and very easy to setup

Install was as easy process - we used the adhesive mounting option on our doors, windows, and walls, and they stick incredibly well. These Detects are very flexible in what they can do. Nice design and the functionality is also superb. They have a feature which allows the user to activate the motion sensor in the device which can ignore small pets. I've tested this with a few small dogs and it's working incredibly well - not once has the alarm triggered with the motion sensors enabled despite the pets walking up/down the stairs where the sensors are placed. Yet, it works very well with people and all other types of motion. Perfect for people with small pets. The Nest app offers great customization options on a per Detect device basis. Great for those who have several of those (as we do) in their home.

Placement is the key to using these, you only get 2 in the secure package. Example in my kitchen u have to walk pass my back door to get to the Windows. So instead of place a secure on window just place on the door since it will activate the motion sensor. When u put the detect on a window the motion sensor is deactivated and only detects if window is open. When it is on a door it does both. So I have 2 more detects in corners on the wall that are angled across the path of the Windows, so system will detect anyone come from window area.

I had the Nest alarm for a couple of weeks. I purchased one of these sensors for every entry to my home including all windows and doors. That was expensive, really expensive. I didn't find the operation of the sensors to justify the expense when compared to what other alarm systems can do for less money. I installed all of the sensors and verified their functionality. I am quite good with technology and fully research how things work before evaluating them. I say this because one of my sensors kept indicating it was off line. This means it would not sense if the window were open or closed. The app doesn't alert you when the sensor is off line, it just doesn't work. You have to open the app, go to each sensor, then review the history of the sensor to see if it went off line. That didn't instill much confidence in the sensor's reliability. I uninstalled the sensor through the app then paired it with the alarm again. Same issue occurred. The issue was with the sensor itself as this sensor was within 25 feet of the base station so proximity wasn't an issue. Given the function of the sensor and the price I don't feel like anyone should have to worry about it going off line so often. The sensors pack a lot of function which is why they cost so much. The quiet open button is awesome, press it and you can open the door or window its on without setting the alarm off. Close it back and the sensor arms again. Each sensor also acts as a motion sensor which adds some convenience. You can install the sensor on a door and you can program it to sense motion and if the door is opened. This saves a bit as you don't need a motion sensor near the doors. Of course you can disable this if you want and it is automatically disabled for windows. Programming the sensors to the alarm is the easiest thing I've ever done with an electronic. You literally open the app, scan the sensor QR code and tell the app where your installing the sensor. It then guides you on how to install it and tests the function when your done. The included mounting hardware can be used with screws (provided) or sticky tape (provided). The sticky tape is strong, no fear of sensors falling off at any point. Given that these go so many other places it doesn't make financial sense to invest in the nest system for a larger home as your windows will end up with expensive sensors that don't use the extra functions. Hopefully Nest releases some cheaper sensors at some point.
