The camera isn't strictly necessary but I like being able to see my airplane and the hangar condition from my iPhone so I think it's worth the cost. The camera will send notifications to your phone if it detects a person, sound or significant change in light. It can also be set to sound an alarm. You can be anywhere in the world and monitor and control your hangar from your phone. I haven't tried this with an Android phone because I don't have one, but the Arduino IoT Remote app is available on the Google Play App Store so it should work the same.
I'm posting this since it took me a lot of time and experimentation to put the hardware and software together and if any other Maule owners are interested in doing something similar, I can save them a lot of time, trouble and money. You are welcome to my Arduino code at no cost. It's not very complex and you can customize it fairly easily if you're into programming. I'd also be willing to help you through the tricky parts such as setting up the Arduino IoT Cloud account and defining the components. As far as physically assembling the components, anyone who is handy can do it but I'd be willing to put the Arduino microcontroller and environmental shield and PIR sensor into a project box since there's a bit of soldering that has to be done for the PIR sensor. I'm not looking to make a business out of this but I don't mind making a limited number of microcontroller assemblies if you want help.
This system is pretty flexible. You could omit all the Arduino Internet Of Things (IoT) components if all you want to do is monitor your hangar with the Lorex camera. If you have wifi at your hangar, you don't need the Verizon mifi and you could save $8.33/month. Just doing that part would drop the purchase cost to about $150.
I'm not going to the hangar today but next time I'm there I'll take a photo of the whole thing and post it. For now, here's a remote photo taken by the Lorex video camera that came off my iPhone.
