"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."

"I regret ever choosing SafeStreets. The whole process was frustrating from the start. The technician who came to install the system was late, didn’t answer my questions properly, and left my house a mess. When I reached out to customer service, I was put on hold for over an hour, only to get a half-baked answer. Save yourself the trouble and look elsewhere."

Home Security Systems questions, answered by experts

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. 

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home. Some wiring may need to be added, but most home security systems do not require a lot of additional wiring. Wireless security systems can easily be installed with minimal additional wiring, if any at all. Most wireless security systems can be monitored and controlled from your smartphone, and the cameras and sensors operate on batteries.

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.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.
