"We wanted to get on board with the current trend in doorbell cameras. Got a quote from ADT Provider, known as Safe Street USA, and felt their offer was more than fair. We have door sensors and motion detectors inside and the doorbell camera mounted outside. Nice to feel “with the times” in home automation and security."

"I had my storm door replaced by Byers security. Mike and Paul did a fantastic job installing it. They took their time and the door fits perfectly. Looks great. Mike was in touch with me throughout the purchasing process. Great company to deal with."

"Protect Your Home group with ADT has exceeding our expectations in getting a new home security system. In the end, everything was a breeze and not stressful whatsoever. We tested the siren and our neighbors 2 doors down could hear it; which is what we were hoping for!"

"Have used Joe 3 times now. First to replace 4 exterior doors. Second to refinish some interior paint and trim. Lastly for a complete kitchen remodel. Each and every time he was prompt and very professional with great attention to detail. He has a permanent place in my address book and will certainly be called on again, probably sooner than later."

"Terrific, we decided to go w/ Stoneberger because their sales representative spent time advising and guiding us through the options, the colors and styles of doors. She listened to what we thought we wanted and helped us find the right solution. No other sales rep we met with offered that customer service. She also followed up on time and was super easy to work with once we decided on specific doors. Installation also was on time, efficient and went very smoothly. We had one issue that arose b/c of the age of our house and Stoneberger addressed it quickly and beyond fairly. Highly recommend them."

Security Doors FAQs, answered by experts

Leaving a light on at night probably does not deter burglars as much as we would like. While there isn’t much evidence supporting the theory that lights deter burglars, there’s not anything disproving it either. If you feel like it offers added security because a burglar thinks you’re at home, then you can set your lights to a timer so they go off and on at intervals, mimicking someone moving around inside the house at night. A better idea is to install motion sensor lights in your yard.

Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

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. 

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence.
