[This review was collected as part of a promotion.] SimpliSafe has addressed a lot of problems that has prevented us from getting a security system in the past.
First, it's insanely quick and painless to set up with the app; I'd say even someone technologically challenged could do it with no issues. And if you don't like installing extra apps, you can complete setup using the keypad (though the app is a little more fluid). I think I had all devices connected and set up in under 30 minutes.
Second (and most important for me) is that NO wiring or electrical is needed to install. Each item is powered by batteries, and camera batteries can be taken out and recharged once low. We have an old 1960 house with very limited electrical capabilities and access. Adding power for cameras or a whole system would be a huge undertaking, if not impossible.
To further simplify installation: if you don't want to use tools and screws to install, just use the command strips included! Perfect for rentals or apartments (camera mounts do need to be installed with the screws however).
Design of all items (and even the packaging) is sleek, modern, and simplistic. They won't be an eyesore in your home.
I have been using my system without a monitoring subscription and have been happy with the range of functionality without it, though subscriptions are only month to month, which makes it easy to add or remove as your needs change. I can view live feed of my cameras any time I want, and there is two way communication available through the camera. I get notifications to my phone when the cameras detect movement (btw the camera's video quality and range of view seem great to me, not being a camera expert by any means) but the only shortcoming is that there is absolutely no recording option without a subscription. The camera holds no footage, so you can only ever view live feed. I know there are at least a couple of brands that do allow a few hours of recorded footage before deleting it from the cloud. This would be the only complaint I have, and the only con that might lead me to look at other brands.
Other than that, the ease and simplicity of set up/installation makes this a more accessible product than your traditional security systems that require a professional installer. No need for electricity provides more flexibility in where you can place certain items that might otherwise be tricky. With a monitoring service this system has just about everything you could want. Without, you lack the ability to record video (it's only downfall, IMO). Overall, a fantastic system.
