See a more in depth Vivint review here. ADT is a well known household name, but what makes it one of the best home security systems?It’s the service and availability, along with the reliability it provides. There are multiple centers for monitoring ADT alarms all over the country, so the chance of an outage is very low. There’s also 140 years of experience backing the company, so you know it has been around long enough to know how to provide customers with what they want and need. Phone and email support are provided on a 24/7 basis, and it’s possible to get an installation completed on the same day. You can also expect $500 off your insurance deductible in case you get broken into while you have ADT monitoring installed. Here’s a quick summary of their pros and cons:You can control your garage door, lights, locks, and more right through your cell phone. There’s no relocation option if you need to move, so ADT works best for established homeowners who are going to be at the same location for a longer period of time. The franchise nature of ADT can also mean that you’ll find a somewhat inconsistent level of customer service and support depending upon where you are based, and that can be frustrating when you are used to receiving good service, but move somewhere else, and suddenly have poor service. On the whole, though, most ADT franchises are very good with customers, and are committed to providing a high level of quality and value for everyone who contracts with them. It’s a DIY installation system, so you don’t have to take the time out of your busy life to wait for someone to come hook things up for you.
