We at ADT-Carolina Smart Home focus on quality services over quantity. We use our years of experience and expertise to complete your project with perfection. Customer service and honesty are the most important aspects of our business and your satisfaction is guaranteed. Please call us today for an estimate. We look forward to working with you.

"The reginal director was very pleasant and he got me signed up the same day to receive ADT services. There was a technician who came in and installed the system. He was also very nice. There was another young man that came in to sell more equipment. When I refused the service he got really aggravated. I had to have my daughter deal with him just to get him out of my home. Now I have realized the camera hasn't worked since it was installed and ADT is trying to charge me another 70 dollars just to come look at it. What Carolina Smart Home did was make a sale, never told me they only have a 90 day warranty with ADT, and they have other aggressive security partners that will try to sell you things you don't need. I wish I'd never responded to Dustin Croom or his associates."

FAQs for alarm or security system installation projects in Greenville, SC

If you terminate your security system before your contract ends, you’ll likely have to pay a cancellation fee—often a percentage of the remaining contract balance. To avoid these fees, consider choosing a brand that offers contract-free plans, like SimpliSafe or Vivint. You can also negotiate with your provider to see if they provide pro-rated cancellation fees or special exceptions.

Paying for a security system is a valuable investment because it enhances your home’s safety and deters criminal activity. With millions of property crimes each year, having robust security measures helps protect your property and might even lower your insurance premiums. It's a worthwhile investment for lasting peace of mind.

The average cost to install security cameras ranges from $125 to $3,500, depending on the amount, type, and placement. To install a complete setup of four cameras, homeowners can expect to invest an average of $1,300 for labor and equipment. Installing multiple cameras gives you comprehensive coverage of vulnerable entry points and enhances overall property security.
