    Used to have Comcast until they got really expensive. Comcast charges $40 per month, they charge $100 per year. You get the same service and it links up with Amazon Alexa seamlessly. Easy to hook up and we have two dogs (small (25lb) and one medium (42lb)). The motion sensors do not see the dogs at all while we are not home.

    Ring is a very nice system, and it will be around for awhile now that Amazon owns them. These Contact Sensors are super easy to setup on doors and windows and make an excellent safeguard for entry points into your home. You can install each of these in less than 5 minutes and be protected for a fraction of the cost that the "professional" services charges.

    We decided to purchase the ring door bell, flood lights and alarm system. We are very happy with everything that we purchased. The ring doorbell works like a charm, the flood lights pick any movements detected and you can talk through the app., and the alarm fee is $10.00 per month. It's a big investment but it's definitely worth it.
