"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

"I HIGHLY recommend Jon and Dena. Their customer service throughout the process (consultation and installation) was stellar! They are very warm and understanding people who do not try to sell you on extra products. The men (Phil & Josh) that came to install the security system were prompt, professional and nice. They were very knowledgeable and TRUST WORTHY! I never write reviews but for this type of service and care, I had to come leave a comment about my experience with security and alert Corp. Iâ m very happy with the work done and how it was done! Thank you!"

"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!

Home Security Systems FAQs, answered by experts

Not all security systems are equal, so familiarize yourself with the many features available and any associated costs. Decide on a wireless or wired system and look at monthly subscription fees to access the service. Finally, read plenty of reviews to check out the efficacy of your intended security system.

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

Instead of a security door, you might opt for a heavy-duty screen door made from durable mesh, which allows better sunlight and airflow. Additionally, you could enhance security by installing strong locks on your existing door. A double-cylinder deadbolt provides robust security; however, be aware that some local laws prohibit them due to safety concerns during emergencies.

While security hubs can streamline the management of security cameras, the placement of cameras itself is often determined by factors like your property layout, security objectives, and areas of concern.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.
