With two neighborhood burglaries, it was time to consider a security system. One I investigated was offering a free Ring doorbell, had armed response from local security force and reasonable fees. I didn’t like the required three-year contract, but I figured that with free installation it was worth it. For another $30 a month, I could have the company’s cars patrol in front of my house and even check on me if they saw that newspapers were piling up. The system can be armed and disarmed with a cellphone app.
