"We didn’t realize how many items could be integrated into our ADT security system. But after speaking with the helpful representative on the phone for about 10 minutes, we decided to go forward with their full home automation package. Not only are the doors and windows secure, but we can control lights, the thermostat, and the garage door."

"Brian provided a fair and detailed estimate and was able to fit me into his schedule fast. He and Terry replaced the rear part of my post and rail fence with privacy panels and build a new gate. They also removed welded wire for me that I had agreed to do but was unable to. The fence looks great and my dogs are secure. I’m very happy with the work and will call again when I’m ready to start work on my front yard."

"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."

"The job went very smoothly. The tech ran a bit late, but he called to say so. He installed a keypad by the front door and assessed the house for security. He suggested, since there are several casement windows in the living room and adjoining dining room that a breaking glass sensor would work better and be more cost-effective than alarming all the windows. He did alarm a door that the previous company (inherited when we bought the house twenty-three years ago) had not considered significant. I feel safer with the current sensor choices than the ones I had before.
He took the time to make sure I knew how to use the system, so I am very pleased with the service. My one caveat: I was told that the motion sensor would not register my smaller pets (two cats) because they weigh under forty pounds. They must have set off the sensor, though, because the police responded. The system certainly alerts the authorities, but that motion sensor is very sensitive!

Security Doors FAQs, answered by experts

A steel door that's been toughened up with extra materials creates the perfect barrier. These bad boys are way stronger than your typical wooden or fiberglass doors, making them a fantastic choice for folks who want that extra layer of security for their homes. So, if you're all about keeping things super secure, a reinforced steel door will cost you more, but it is your best bet.

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.

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