The idea of this home monitoring device is pretty interesting: 1. A wide angle camera to recording when it detects motion. 2. An app that receives a notification and allows you to view the recorded motion video. 3. A graph and monitoring of air quality, temperature, humidity, and weather. 4. All of this in a nice looking device that you can hang on your wall. When I got the Sentri, I plugged it in and followed the on-screen instructions to set it up. In connected it to my home's WiFi and the setup was very quick. There isn't much to it. You basically create an account, name your Sentri, and it's good to go. There is an iOS app that you can download and login to your account, and you'll be able to access your Sentri remotely and receive notifications. I downloaded the app, and immediately noticed that it's just an iPhone app, and not universal. It would be great if the app worked natively on the iPad, and especially cool if it also worked on the new AppleTV. I don't "expect" it to work on the AppleTV, but I do expect it to work natively on the iPad. On my iPad, I could run it just fine, but it's an iPhone app that is pixel doubled. What I noticed was that I was only able to access the Sentri remotely about 75% of the time. Most of the time, it would unfortunately tell me that it could not access the Sentri. Of course, I tried to delete and reinstall the app, I checked my phone's internet connection, and tried to connect via LTE and WiFi. Nothing. I also rebooted the Sentri, and made sure that the Sentri was on my network. (Look for an item on your network called DOMEX to get it's IP address). I found it's IP address and could ping it. I also tried to connect it via ethernet, but it didn't help the reliability. The Sentri has two modes, a home mode (no alerts) and an away mode (alerts). When set to Away, when I walked in the door, I would get a push notification on my iPhone and when I opened it, it would take me to a screen in the app where I could watch the video, or view the video live. That's a VERY USEFUL FEATURE because that's exactly what I want to do. If I get an alert, I like that I can immediately see the live video also. If it's dark, it uses IR to light up the room, and it does this very well. The temperature and humidity sensors were very close to what my Nest thermostat nearby was reporting, so I was happy with that. Overall, it's a nice device. Imagine an Android tablet in a large enclosure, that you can place on a desk or mount on the wall. It's clear that it's Android, but it has a very limited UI. You can change the wallpaper, see the time, temperature, humidity, air quality, and weather. You can also see some settings, and a timeline of events. I also like that it received updates several times, and I believe over time, it'll probably get much better. I would like to see a MicroSD slot so that I can record locally in addition to the remote cloud recording. Speaking of the cloud recording, the prices are good. With a competitor like Nest, for $99 you get a year of viewing the last thirty days of videos. With the Sentri, you get the last YEAR of videos for $99 a year. Now that's a good deal. Even better, for free, you get 7 days of alerts and video. I gave it three stars because the connection issues I encountered need to be fixed. They happened often enough that I really wasn't surprised when I couldn't access the Sentri. Like I said, it wasn't just my phone, the device itself was not accessible. You can see from my pictures that Android actually crashed also, but, since then there have been software updates which may have fixed that problem. They are really good about responding to people and roll out updates, so I'm hopeful for updates that fix a lot of these problems. The idea behind the device is nice, once they get the device completely consumer ready, it'll be great. I did receive this device at a discount in exchange for my unbiased and honest review.
