"This company is absolutely fantastic! Tony is so professional and a really great guy. He bid me a price for some work that turned out to be much more complicated than originally thought. He did not try and increase his price and did the work for the pre-determined rate. In addition, I had a tv he was supposed to hang that was brand new in the box. When he opened it, he discovered the screen was shattered. I was able to return the tv and he is coming back out on a separate trip to hang it. He has really gone above and beyond. I cannot recommend him more highly."

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."

Home Security Systems questions, answered by experts

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

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

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.

A steel door that's been toughened up with extra materials creates the perfect barrier. These bad boys are way stronger than your typical wooden or fiberglass doors, making them a fantastic choice for folks who want that extra layer of security for their homes. So, if you're all about keeping things super secure, a reinforced steel door will cost you more, but it is your best bet.
