"Got going with ADT system earlier this Fall. It has been good. Still getting used to a much fancier and dynamic system. But it was time for an upgrade and we would suggest ADT to anyone looking to secure their home or their business."

"We couldn’t have asked for a better outcome. Steve was able to come out on the day that we called; was prompt, professional and was able to diagnose and repair our legacy Ademco alarm system in relatively short order. Will definitely use again. Highly recommended."

"We like their service. We haven't had any problems. They are very good. This was the first time we've had an alarm/security system in our home. The supplier is ADT. I like that I can set my alarm every night before I go to bed."

Home Security Systems FAQs, answered by experts

The main difference between different security sensor options is the type of motion each detects. A motion detector monitors obvious movements in hallways, entrances, and exits. On the other hand, a presence detector is more sensitive and captures smaller moves. A window sensor typically focuses on the opening and closing of the window, whereas a glass break sensor alarms you when a glass is broken.

Professionals optimize camera placement, integrate recording systems, and ensure tamper-proof security.

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.
