"For Security Systems, this is the place to go. Yes, I had ADP quote my project, but Modern Tech was by far the best option. Not only is it a local company, but the professionalize, value and price made it an easy decision, plus there was not a three year contract! Robert was the installer and he was fabulous at explaining options (personalized to what I needed) and how everything worked. He was also very responsive to the follow-up questions I had. I highly recommend using this company for your surveillance and alarm system needs."

"Jack and Eric at Vantage Security Installation went above and beyond from the initial consultation to the final walkthrough. They took the time to explain all of my options clearly, helped me choose the best setup for my home, and worked efficiently on installation day. I would highly recommend this company to anyone looking to get security cameras!"

"After a thorough telephone inquiry to explore possible causes for our home security system shutdown, Chad offered a house call the following day to confirm his suspicions and restore operation. He showed up when promised, identified equipment problems at two sites, replaced two system batteries -- one beyond restoring and one getting old -- and gave us very helpful information to relay to the next owner of our home, which will be on the market later this year. He clearly answered every question. His trip charge from south Metro Denver to our Broomfield location was quite reasonable, and the only other charge, for the batteries, was modest as well. We felt lucky to locate someone with Chad's expertise and prompt response, and would highly recommend him and his company, Custom Protection, to anyone with a home security system problem. Thanks, Chad!"

Home Security Systems FAQs, answered by experts

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Insurance companies weigh the amount of potential liabilities on your property to increase (or decrease) the cost of your home insurance. They will use several factors to decide if there are more chances for peril or injury to take place at your home. These factors include your location (whether you live in an area with high risk for natural disasters), the age and condition of your home, and whether you have any “attractive nuisances”—features that both increase the aesthetic of your home and potential for injury—like a pool or treehouse. 

The average cost to install a home security system is about $750. However, the price can range from as little as $200 for a simple wireless camera setup to $2,000 for a fully monitored, hardwired system. A typical price range is $280 to $1,150. Several factors determine the final cost, including the type of system, equipment, materials, labor, activation fees, monthly surveillance fees, and permits. Optional upgrades will also add to the price, such as video surveillance monitoring ($40–$65 per month), smart locks ($150), smart lighting ($15–$90), smart smoke and carbon monoxide alarms ($35–$100), and a smart thermostat ($130–$500).

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.

Expect to spend an average of $150 to $500 to set up a home flood detection system. However, be aware that costs are wide-ranging. You might only spend a budget-friendly $50 to place basic, battery-operated sensors in a few key areas of your home, or $150 to set up two or three smart sensors. The purchase and professional installation of a whole-home protection system with water shutoff capabilities could cost between $500 and $1,000.
