Home Security Systems questions, answered by experts

Yes, evaluating needs based on home size, layout, and climate.

The most secure lock for a front door is typically a deadbolt. There are many types of deadbolts to choose from, the most basic of which is the standard single-cylinder deadbolt. This is the lock you find installed on most front doors. For added security, you could go with a double-cylinder deadbolt, which requires a key to operate the lock from both the outside and the inside. 

Technically, there isn't a difference between safe rooms and storm shelters. Both are designed to protect you from storms and extreme weather events. People often use “safe room” when discussing a shelter inside a building and storm shelter when talking about a detached unit. 

Additionally, a safe room is understood to have more functions than a storm shelter. You may seek shelter in a safe room when you believe an intruder is in the home or when under another type of threat. 

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

A deadbolt has a different design, construction, and security level than a regular lock. Regular locks are mostly used for interior doors around the home, like bedrooms and bathrooms, and they usually include a locking mechanism on the inside. While regular locks are easy to use and install, they provide little security. 

A deadbolt adds a layer of security and is most commonly used on exterior doors. The installation is typically more complicated, but they hold up to wear and tear.
