"It went great!  From Travis the sales person to Noah the installer I couldn't have asked for a more professional and through team to deliver my home security needs.  We just bought a new house in a neighborhood that's up and coming but there's still an element that we want to protect our home and valuable from.  Security One helped us find a system that we could monitor while we're away and that would make my girlfriend feel safe when I'm not a home.  We highly recommend them especially Travis and Noah.  Ask for them by name!

"We like their service. We haven't had any problems. They are very good. This was the first time we've had an alarm/security system in our home. The supplier is ADT. I like that I can set my alarm every night before I go to bed."

Home Security Systems questions, answered by experts

A home security system can be a worthwhile investment for several reasons. Financially, it may qualify you for a discount of up to 20% on your home insurance premiums, which can help offset the initial setup costs and any ongoing monitoring or subscription fees. For many, the primary benefit is the peace of mind that comes with enhanced security, especially for those living in areas with higher crime rates. Ultimately, whether a system is worth it depends on your personal preferences, the value of the assets you wish to protect, and your overall safety concerns.

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

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. 

Yes, driveway gates can help secure your home by deterring burglars from accessing your property. Climbing a gate slows down burglars while also attracting attention to your gate. If you live further down your property and want to increase security, you can also install a gate security camera that connects to your gate and monitors the area for suspicious activity.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.
