Home improvement company are not like that ADTs and Vivints of the world. Rather than signing up for a multi-year contract with a broad coverage-based subscription fee, most DIY security systems give you the flexibility to decide how and when to monitor your home.

That usually means that you can optionally sign up for a professional surveillance service and cancel at any time – with no early termination fees or other hidden fees. Factors we considered included the quality of the surveillance cameras (do they have motion detection and night vision?), Is there a surveillance plan, can window sensors and door sensors be integrated, whether the system has a mobile app, can it work with yours? Door locks and can be integrated into an existing smart home setup, also with voice commands via Amazon Alexa.

SimpliSafe Home Security

SimpliSafe was one of the first home improvement security systems to go on sale and is a reasonable alternative to ADT and other professional companies. This is in large part due to the wide range of accessories available. The starter kit is only $ 230 and recently underwent a hardware update that looks a lot better than before.

You still have to pay a minimum of $ 15 monthly fee to access remote security features (something usually offered for free with other systems), but SimpliSafe's impressive range of accessories and solid performance make it ours first choice.

Abode has all the standard sensors and devices for a simple entry-level security system. It integrates with Amazon Alexa, IFTTT and Nest for voice-controlled activation and deactivation as well as other advanced automation. You can add accessories to the system à la carte. Professional surveillance is available for $ 30 per month and includes cell phone backup.

It also supports ZigBee and Z-Wave, which means you can connect the system to a wide variety of third-party devices so you can control everything from the Abode app.

I wish you didn't have to use Abode's web app to create custom rules and automations, but this scalable self-installation system offers reliable performance at a good price.

The $ 499 Nest Secure Alarm System Starter Pack includes a guard hub, two tag key fobs, and two door / window / motion sensors for detection. You can activate and deactivate the system by entering a PIN code on the Guard's built-in keypad, tapping a paired tag above the Guard hub, or changing the mode in the dedicated Nest app for Android and iPhone.

The detection sensors are my favorite part of Nest's secure system because you can temporarily turn off a single detection while you continue to monitor the rest of your home. This way you can open a window, get the paper from your front yard – and much more – without having to deactivate your Nest Secure system.

If you want a simple home security system at an incredible price, consider the second generation Ring Alarm Security Kit. Version 2.0 was introduced this year and is very similar to the original – and that's a good thing.

The eight-piece kit I tested, including a base station, keyboard, range extender, motion detector, and four door / window sensors, costs $ 250. In addition to its affordable price, the Ring Alarm Security Kit has a simple app, is easy to install, and the entire system works perfectly.

You can scale it with additional Ring devices, including ring security cameras and doorbells, and even add select third-party smart locks and other products. The kit works with Alexa, so you can activate / deactivate the system with voice commands – and Ring offers optional professional monitoring for $ 10 per month or $ 100 per year (also great value for money).

Definitely consider this system if you want a basic entry point into home security that can also be expanded over time if needed.

If you have any concerns about Ring's privacy and security policies, read this comment.
