We opened our business in the spring of 2009. We started as a home theater wiring and installation company. As time pressed on it was clear that most home owners wanted someone that could take care of more than just a home theater, and since technology has evolved in the past years we have had to adapt now offering complete Smart Home Technology. Smart home options typically will integrate Security Surveillance Door locks Thermostats Garage doors, and so much more.

"I purchased a house with an existing security system. JR came out and was able to tell me exactly what I needed to update the system. During the installation the guys walked me through how to work everything. Very happy I went with DST Security."

"Project was to take 3 to 4 days, it took 8 days worked approximately 4 hours per day. Project started 11/6/24 provider "finished" on 11/19/24. Floor covered with caked drywall, mud and paint. Paint on my kitchen and utilty room floor which is next to the bedroom being repaired. I can see tape and mud through the paint, missing and unattached baseboards, smoke detector was not installed, windows and door frames are not acceptable no where close to how they were attached before the work started, gaps at the light switch and plug face plates. Paint on the closet floor. I can see the tape on Ceiling through the paint. I had to pay to have them dispose of the removed drywall. A shovel was used against my floor to remove the drywall since the floor is caked with drywall and paint,I have no way to know if there is any damage to my laminate floors."

Alarm or security system installations FAQs

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.
