"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."

"About 4 years ago I need my home protected by something other than my dog while I was not home looking for a job. I needed something affordable, simple to use and install my self as my house was not prewired. I found Protect America and it had all I needed and more. Over the years I have added to my system more sensors, motion detectors, camera's, carbon monoxide sensor, and monitored smoke detectors. All of it was simple enough to do with some help with their Installation Technician walking me though everything on the phone. I have had other companies try to get me to switch to them, but what I have works and they could not beat the price so I told them no thanks."

"LOVE this system!  Customer service was extremely nice and made my experience effortless.  Speaking of effortless, the self-installation was super easy.  It took me less than 30 minutes from start to finish to get my system up and running.  Highly recommended!"

Home Security Systems FAQs, answered by experts

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.

Ultimately, the decision should align with your objectives. For general home security, visible cameras at entry points and high-traffic areas are recommended to deter intruders. In areas where privacy is a concern, use hidden cameras sparingly and within legal limits.

Security cameras do not need wiring if they are wireless, meaning they are battery-operated and can connect through Wi-Fi. You’ll need to change the batteries on a wireless camera and ensure you have a steady connection to Wi-Fi for video storage. If you have a wired security camera, you’ll need to plug it into an outlet or other power source and a DVR device.

One significant drawback of home automation is the increased risk of cybersecurity threats. With more connected devices in our homes, there's a greater chance that hackers might try to exploit vulnerabilities to access personal data or even control your devices. If you don't secure your smart gadgets properly, they can become entry points for cyberattacks, risking your privacy and safety. Moreover, technology isn't perfect. Sometimes, systems can malfunction or experience connectivity issues, disrupting your daily routines. The upfront cost of buying and installing smart devices can also be a hurdle for some people. 

Whether a security system or security cameras is a better choice for you depends on your needs and preferred comfort level. A security system can cost more depending on the features you choose, but it’s a more proactive and protective approach to home security by alerting you and authorities of any emergencies. Using a security camera system is a more reactive approach because while you can monitor the camera footage, it does not alert the proper authorities for you.
