"Last weekend had someone pry our side door open to our exterior garage and the ADT door sensor picked it up immediately. The alarm siren was loud and scared the person off. Someone from the response center called within 30 seconds. We’re fortunate that the security system did what it is supposed to. Feels like we made the right call going with an ADT security system."

"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!

"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."

"Protect America Alarm Systems are wireless home security systems that are so advanced and yet uncomplicated that the consumer can install all components to the system themselves. Tech support is provided which makes installation easy and very user friendly. The system is monitored and response to alarm signal is quick and nearly immediate. ( I accidentally set it off a couple times having forgotten that it was set when we left home). I've had a couple different systems in my homes over the years which were "professionally" installed; one was wired the other wireless. I install this myself with the help of tech support, I'm 65years old in good health but of course not as agile as I was a few years ago, but this system was a piece of cake for me to install. Every access to my home has been covered as well as some interior sensors. All of which have functioned flawlessly from day one!

Security Doors FAQs, answered by experts

A security camera company will be able to advise you on where to position the cameras, ensure all of the equipment is set up properly, and do all of the installations. They’ll take factors into consideration that a non-professional might not automatically consider, like obstacles that could block a potential trespasser from the camera or how lighting may obstruct the view.

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.

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.

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.

DIY is possible for wireless cameras, but professionals ensure optimal angles, security integration, and network stability.
