Your Guide to DIY Home Security Systems

Written by |

Money expert Clark Howard says homeowners who want to build their own security systems have plenty of good options in a wide range of prices.

In this article, I’ll highlight some of Clark’s picks for home security systems that you can install yourself.

Final Thought

Home security means different things to different people. It could be motion-detecting lights, surveillance cameras or a plethora of “smart home” options from doorbell cameras to facial scanners.

Before you spend any money, you should decide what you need to feel protected and have peace of mind.

Once you answer that question, determining your budget and the gear you need should become a lot clearer.
