"My next door neighbor's house was robbed last week, and I realized that I needed to do something to give me further peace of mind. Purchased new home security with ADT and opted to get the premium options with flood detection and carbon dioxide monitoring. Keep up the nice job ADT!"

"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."

"We have our second home in the mountain so they were able to send it and he was able to work with our installers and it worked out fine. So far we were are pleased with it. We were with another security system for 12 years and we changed because their selection of product was of a higher grade. They are excellent."

"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."

"Yvette Pringle provided courteous and professional feedback to me when I called to inquire about a new home security system.  My situation was unique because we were trying to find something that would work for a deaf person.  I appreciated that Yvette did her research to find out what would work.  She also offered different options in terms of a package and plan.  We did end up going with another company, but I really did want to recognize Yvette for her work.  She was very polite and helpful.

Security Doors FAQs, answered by experts

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.

It depends on the type of sensor your home security system uses. If it’s a motion detector, any moving thing could set it off, from a roaming pet to a wind-blown curtain. Contact sensors would be triggered by the window being opened or moved. Also, be aware that any sensors placed too close to your vents could trigger false alarms whenever your heat or air conditioning is running.

Strike plates and security plates are the same thing, but there are strike plates that offer more security than others. For the highest security, look for plates made of heavy-duty steel, reinforced strike plates thicker than regular ones, and extended strike plates. It’s much harder to break into a door with these strike plates because they hold up better to force from attempted entry.

Professional home automation services can include automation for nearly anything in your home, so the possibilities are endless. Some of the more common things homeowners use automation for include the following:

  • Heating and cooling for automatic comfort

  • Security cameras and emergency call systems

  • Door and window sensors to detect opening, closing, and break-ins

  • Solar system automation to maximize energy savings

  • Automatic door locks

  • Garage door openers

  • Speaker systems

  • Lighting

  • Appliances

  • Smoke and CO detectors

  • Blinds and other window coverings

  • Lawn irrigation systems

  • Water monitoring

A home security system can be a worthwhile investment for several reasons. Financially, it may qualify you for a discount of up to 20% on your home insurance premiums, which can help offset the initial setup costs and any ongoing monitoring or subscription fees. For many, the primary benefit is the peace of mind that comes with enhanced security, especially for those living in areas with higher crime rates. Ultimately, whether a system is worth it depends on your personal preferences, the value of the assets you wish to protect, and your overall safety concerns.
