I stupidly left my front door unlocked last week. Murphy’s law, I awoke at 2 am to someone walking through our house. I was able to call 911 and we are safe. However, I would like to install a security system that I have to arm each night to prevent something like this again.
The prior owners used Nest, so everything is wired already for that. However, I am looking for suggestions on the best systems. I would prefer to not have a camera. Thanks!
