"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

"Mark responded to my request in 3 minutes. He visited the following day. He corrected my security system on that visit allowing me to leave home for a trip the next day. I was satisfied that he understood his craft and did the work in the time projected. I would use him again and recommend his services strongly."

"Wes did an outstanding job for us!! We installed a security system and upgraded our home audio system. First he did an evaluation of our needs and made recommendations to help us accomplish our goals. He was very knowledgeable and provided excellent advice including upgrading our wifi system so that the final installations would perform as intended. His pricing was fair, he always responded promptly and scheduled and completed the work on the dates he promised. I would highly recommend Wa/ve Sound & Security!"

"Great company to deal with. Totally customer focused. My wife was not comfortable with me installing our security system myself, so internet based alarm companies were a no go. I contacted our existing company, Vector, Vivant, ADT & 1st Security. I met with all of the reps. Jeremy from 1st Security came to our home right away to conduct a detailed security assessment. He listened to our needs and our concerns with our existing landline based security system (through Vector), and he designed an effective yet practical and affordable set up for our home. Their prices cannot be beat- trust me I did my homework. Larry came to install the new security system and he was also great to deal with. Knowledgeable and patient- he took his time to explain how the system worked and gave us his cell # in case we had any issues. Kudos to 1st Security USA! Great folks doing business the way it should be done- honest and professional. I will be spreading the word"

Home Security Systems FAQs, answered by experts

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

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.

While many security cameras rely on an internet connection to transmit footage and store it in the cloud, not all of them stop working when the Wi-Fi is off. Some models are designed to function offline by using local storage options, such as a microSD card or a network-attached storage (NAS) device. These cameras can continue to record footage even without an internet connection. You can then access the stored data once the Wi-Fi is restored.
