"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."

"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."

"I switched from another company to Security One, they use the same equipment. They had to come out and recode everything. I simply switched because of the financial benefit. I have only had them for a few months, and I haven't had any problems with them. They save me some money every month.  When my alarm went off, they did call me."

"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

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.

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.

Hiring a professional ensures optimal camera placement, secure installation, and integration with existing security systems. Professionals ensure reliable operation and can offer system customization to suit specific security needs or preferences.

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.

Home automation systems offer a wide range of automation products and services. Some of the most popular options include:

  • Cameras: $35–$350

  • Door and window sensors: $20–$100

  • Doorbells: $100–$350

  • Locks: $150–$400

  • Garage door openers: $150–$500

  • Lighting: $20–$100

  • Speakers: $30–$300

  • Outlets and plugs: $20–$100

  • Thermostats: $150–$300

  • Smoke and carbon monoxide detectors: $50–$150

  • Smart home hubs: $200–$900

  • Blinds: $50–$75

  • Appliances: $50–$3,000

  • Vacuums: $200–$1,200

  • Lawn systems: $80–$300

  • Wi-Fi and Mesh systems: $200–$500

  • Water monitoring: $100–$1,000
