There was once a time when home security meant shelling out thousands of dollars for high-end cameras, motion sensors, and professional set up. These days, however, home security systems are both smarter, and more affordable, plus, you can set them up all by yourself — no expert installation needed.

Of course, there are quite a few home security systems on the market, and some are clearly better than others. A good security system features motion trackers, security cameras, and even smart home connectivity to give you alerts on your phone and the ability to track your home's security on the go.

When choosing a home security system, you'll want to think about the smart home standard you want to use. For example, you may want the system to integrate with Samsung SmartThings, IFTTT, Wink, Nest, Amazon Alexa, or the Google Assistant. Some systems work with more smart home gadgets to give you a fuller picture of your home environment, including everything from open windows to leaky sinks.

You'll also have to make sure that you're comfortable setting up these new wirelessly connected home security systems by yourself. If not, you'll have to go to a professional like ADT, which costs more. However, the systems we've included are easy to use and set up, so you shouldn't have a problem with them. It's also important to note that you need strong internet to support all of these smart home products.

Last but not least, you'll need to think about any monthly fees. Often, you'll have to pay monthly fees for things like cloud video storage and other security features. — Christian de Looper
