"I’ve had nothing but problems with SafeStreets. The installation was a mess—took hours longer than promised, and the technician seemed clueless about the system. When I called customer service, they were rude and unhelpful. The security system itself is glitchy and keeps going offline. Definitely not worth the hassle."

Home Security Systems questions, answered by experts

In most cases, installing a driveway gate will improve the value of your home. Driveway gates appeal to homebuyers because they provide additional security for the home and make your property more private. Automatic driveway gates are extra convenient and will usually add more value than manual ones. The gate material will also affect the value addition to your home, as it plays a role in aesthetic appeal and security for your property.

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

Home security cameras typically do not record continuously 24/7. Most options use motion detection technology to trigger recording when they sense movement or a significant change in their field of view. This approach conserves storage space and reduces the need for constant monitoring. When motion is detected, the camera starts recording and may send alerts to the homeowner. However some cameras offer the option for continuous recording, but this requires substantial storage capacity and may overwrite older footage when space runs out.

Some but not all security cameras have monthly fees, depending on the specific camera system and the services offered with it, especially monitored vs. unmonitored security systems. Home security companies that offer monitoring services along with cameras will charge a monthly fee for monitoring and possibly for using the security cameras. Cameras that you monitor yourself as part of your own security system will not have monthly fees charged.

While a strong conventional deadbolt offers enough security for most homeowners, if you’re looking for extra features beyond just simple locking, smart deadbolts are the way to go. Smart deadbolts allow for keyless entry using your phone or a code, remote access in case someone is locked out, and features like temporary access codes, automatic locking, tamper alerts and entry-exit monitoring. Smart deadbolts also come with downsides: they rely on batteries and wireless networks and are potentially vulnerable to hacking by skilled home intruders.
