"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

Home Security Systems FAQs, answered by experts

It depends on your specific needs. A security system typically includes alarms, sensors for windows and doors , and 24/7 monitoring services, offering comprehensive protection with immediate response to potential threats. Cameras, on the other hand, primarily provide visual surveillance and evidence collection. A security system is preferable if your primary concern is deterring intruders and receiving real-time alerts. Cameras are ideal for monitoring and recording activities but might offer a different level of active protection. In many cases, a combination of both—a security system with integrated cameras—provides the most robust home security solution, offering prevention and documentation.

Although some pet doors allow easier access for burglars or stray animals, there are ways to make pet doors more secure. To increase your home’s security, choose locking or electronically activated doors, use additional motion sensor security cameras, and install pet doors on a wall where door locking mechanisms are difficult to access.

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, daytime visibility for security cameras ranges from 10 to 70 feet. Higher-end cameras may have night vision that records 100 to 200 feet out. When shopping for any type of security camera, it's important to pay attention to focal length, resolution, and infrared technology to get an idea of the depth and crispness that will be used when capturing images.

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.
