From what I understand, it’s not so much a matter of just buying a device, but also programming it to the exact frequency that matches your alarm system. (Which makes an interesting case for not using a security sign, but that’s another debate.) That said, a really good signal jammer can cost upwards of $1,000, and as CNET pointed out, they would still have to smash a window or break down your door. The guy who wants money for his addiction isn’t going to spend the money and effort needed to pull off a jamming heist. Of course, if you are a public figure or might be the target of a more complex attack, I would suggest looking into a wired alarm system.
The company’s latest product, the $199 Ring Video Doorbell 2, was released earlier this summer, and it improves upon the original product in a number of ways. It provides higher-resolution video output — 1080p verses the 720p of the original — and makes it easier to recharge the unit’s internal battery if you don’t have it hardwired into your home’s electrical system.

I've owned the Ring Video doorbell for about 6 months and it has been a very pleasant experience. It was very easy to install and easy to use. It has never stopped working or had any major issues. This doorbell lets me know when I get packages delivered, when people approach my door, or ring my doorbell. It is very convenient. The only issue I've had is with motion sensitivity. I get a ton of motion notifications from cars on the road, which are about 35 feet away from the doorbell. It seems very accurate with detecting people but it has an issues with cars, especially large vehicles.
