"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

"They gave us the best rate and the setup was great for ADT system. The installer did have to tell us about other options that would cost more money but he did not pressure us when we declined. We had door, window and motion detectors included. They gave us a week to practice on the new system, but we could call if we were ready to go live sooner which we did. Set up was quick, easy and uneventful. Very nice installer, Phillip Brown. The cost was quoted at a low price, but the bill came from ADT and was much higher. We were told the contract to ADT did not catch up and we will be getting the lower price with a reimbursement for the excess of the first bill. We did the $99 install and are getting a $100 gift card back. 3 year contract is a little annoying but we plan to stay here for a long time."

Home Security Systems FAQs, answered by experts

A deadbolt differs from a regular lock in its design, construction, and security level. Regular locks are typically used for interior doors, such as for bedrooms and bathrooms, and provide minimal security. They are easy to install and use, often featuring a simple locking mechanism on the inside. In contrast, a deadbolt is one of the most secure locks you can install on an exterior door. Its internal construction is designed to withstand significant force, adding a crucial layer of security that can deter intruders. While deadbolts may be more expensive and complicated to install, they are cost-effective for the security they provide and are built to hold up to wear and tear.

Technically, there isn't a difference between safe rooms and storm shelters. Both are designed to protect you from storms and extreme weather events. People often use “safe room” when discussing a shelter inside a building and storm shelter when talking about a detached unit. 

Additionally, a safe room is understood to have more functions than a storm shelter. You may seek shelter in a safe room when you believe an intruder is in the home or when under another type of threat. 

You don’t need to completely revamp your security system constantly, but it’s a great idea to give it a once-over every year. Look for potential upgrades or new features—like smart home tech or replacing outdated equipment—that could boost your safety. If you make any significant changes, let your insurer know as they may adjust your discounts to reflect your improved security. Staying on top of your security not only keeps your home safe but ensures you’re getting the best possible rate on your insurance.

Faulty sensors, weak signals, false alarms, and control panel malfunctions are common problems requiring repair.

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.
