"My next door neighbor's house was robbed last week, and I realized that I needed to do something to give me further peace of mind. Purchased new home security with ADT and opted to get the premium options with flood detection and carbon dioxide monitoring. Keep up the nice job ADT!"

"Delivery was delayed due to credit inquiry. After the concern was raised, shipment was rushed to us. Self installation didn't go as easy. Issue was resolved over the phone. The glass break sensor was a bit sensitive to loud noise such as cabinet door closing and door sensor repeatedly falls off and had to be reattached. Notification of alarm activation was fast and made to the right contact numbers. This prevented false alarm calls to the police."

"We have our second home in the mountain so they were able to send it and he was able to work with our installers and it worked out fine. So far we were are pleased with it. We were with another security system for 12 years and we changed because their selection of product was of a higher grade. They are excellent."

"That's the name I am vaguely familiar with; it's a home security company that is license to ADT franchise or dealer if I am correct.  They were very good.  They were prompt; they were quality.  The individuals move their business.  They were very timely and it was a good experience."

"Yvette Pringle provided courteous and professional feedback to me when I called to inquire about a new home security system.  My situation was unique because we were trying to find something that would work for a deaf person.  I appreciated that Yvette did her research to find out what would work.  She also offered different options in terms of a package and plan.  We did end up going with another company, but I really did want to recognize Yvette for her work.  She was very polite and helpful.

Security Doors FAQs, answered by experts

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.

Yes, driveway gates can help secure your home by deterring burglars from accessing your property. Climbing a gate slows down burglars while also attracting attention to your gate. If you live further down your property and want to increase security, you can also install a gate security camera that connects to your gate and monitors the area for suspicious activity.

Yes, many providers offer remote troubleshooting and monitoring for business networks.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.
