"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 questions, answered by experts

Some Christmas lights are marked as being “UL Safety Certified” or Underwriters Laboratories Safety Certified. This lab is a trusted source for determining the safety standards of electrical products—you should make sure your Christmas lights have this label. Brush up on other electrical safety tips before installing any lighting features. 

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. 

Yes, evaluating needs based on home size, layout, and climate.

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home. Some wiring may need to be added, but most home security systems do not require a lot of additional wiring. Wireless security systems can easily be installed with minimal additional wiring, if any at all. Most wireless security systems can be monitored and controlled from your smartphone, and the cameras and sensors operate on batteries.

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.
