"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."

"This was the third company we contacted after having no follow through with the first two. I explained to Ramiro of Northbay Technology what our problem was. He had a technician here in a few days, he fixed the problem as well as giving us useful feedback on our system. Our streaming and dvd system work after not having it for almost 3 months! Ramiro also called afterwards to make sure everything was still working. What a treat to find a quality company that does what they say they’ll do and also offer great customer service."

Very nice contact person called when running just a little late very close to the time of appointment. Also suggested I could remove the system myself but would do be able to do the work if I preferred. Would recommend this company for any security work needed."

Home Security Systems questions, answered by experts

It depends on the type of sensor your home security system uses. If it’s a motion detector, any moving thing could set it off, from a roaming pet to a wind-blown curtain. Contact sensors would be triggered by the window being opened or moved. Also, be aware that any sensors placed too close to your vents could trigger false alarms whenever your heat or air conditioning is running.

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. 

The main difference between different security sensor options is the type of motion each detects. A motion detector monitors obvious movements in hallways, entrances, and exits. On the other hand, a presence detector is more sensitive and captures smaller moves. A window sensor typically focuses on the opening and closing of the window, whereas a glass break sensor alarms you when a glass is broken.

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to.
