"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"We hired Martin Networking to install surveillance in our retail space. Jesse was professional and knowledgeable the entire way through the process. Prompt to our consultation, experienced with offering recommendations on placement of cameras and different styles available to give us the coverage we needed. The install was handled flawlessly. He was respectful of our space and kept all wiring concealed for a clean finish. After the install was complete, he made sure to follow up with a thorough explanation of the features of the cameras we selected and made sure we were comfortable accessing the app and adjusting settings to fit our needs. An additional trip was made for a minor adjustment on the angle of one camera and we have been very pleased with the performance of what was installed. So satisfied with service and product, we are having cameras installed at our home next. "

Home Security Systems questions, answered by experts

Not all security systems are equal, so familiarize yourself with the many features available and any associated costs. Decide on a wireless or wired system and look at monthly subscription fees to access the service. Finally, read plenty of reviews to check out the efficacy of your intended security system.

Home automation systems offer a wide range of automation products and services. Some of the most popular options include:

  • Cameras: $35–$350

  • Door and window sensors: $20–$100

  • Doorbells: $100–$350

  • Locks: $150–$400

  • Garage door openers: $150–$500

  • Lighting: $20–$100

  • Speakers: $30–$300

  • Outlets and plugs: $20–$100

  • Thermostats: $150–$300

  • Smoke and carbon monoxide detectors: $50–$150

  • Smart home hubs: $200–$900

  • Blinds: $50–$75

  • Appliances: $50–$3,000

  • Vacuums: $200–$1,200

  • Lawn systems: $80–$300

  • Wi-Fi and Mesh systems: $200–$500

  • Water monitoring: $100–$1,000

In general, keyless door locks are considered safe. They can’t be picked like a traditional lock, and unless a thief can guess your code, it’s pretty tricky to break into a house with a keyless door lock. But that doesn’t mean they come without risk. 

When asking yourself, "Are keyless door locks safe?” consider the style of the system. Hackers could potentially break in if it operates on Wi-Fi, but it’d take some time and effort. You’re also at risk for a power outage, depending on the type of lock. That being said, there are no more risks associated with keyless door locks than a traditional lock.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.
