DIY alarm systems

I’m looking for a hardware system capable of triggering an alarm and sending notifications to a cell phone in case of a break-in. I need sensors for a few windows and doors, and I prefer not to incur subscription fees. I’m open to setting up both hardware and software. What options are available, and what would you recommend?

The Arlo free plan would be a great option.
Offering an All-in-one sensor, great camera and self-monitoring options, easy installation as well as video verification, it could be worth considering.
However, you should watch out for its weak smart home compatibility and some setting difficulties in the app.
But overall, it is a nice choice.

You can consider Simplisafe. Although the Pro monitoring starts at$19.99/mo, you’ll get to enjoy such benefits as:

  • No contracts
  • 60-day money-back guarantee
  • Uncomplicated equipment
    Its setup is also easy as well as affordable equipment
