"With crime and break-ins picking up around the city, we felt it was time to invest in home security. Using ADT for the entire process was excellent. They added an extra motion detector to our equipment package for being new customers. We also added the smoke and carbon monoxide detectors. All and all, a great overall security and automation system."

"We were with another monitoring company and Lloyd Security helped us throughout the transition and even sent the cancellation request for us. They made sure that careful attention was given to the aesthetics of the installation because we did not want wires to show or have extra holes drilled. They showed up when expected and completed the job the same day as promised. It's nice to deal with a business that is not only courteous, but prompt, careful and knowledgable."

"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!

I originally called ADT Security to set up a system in my home and was sub contracted out to Protect Your Home which is but ISN'T ADT. I greatly feel like I was rushed through my phone call and things were not clearly explained. My home owners insurance actually went up! USAA is supposed to get a discount with ADT however since it was subcontracted out without my realization I will not be receiving a discount on my monthly bill. They push PULSE like nothing else and make you feel like you are basically under attack. "What if the phone lines are cut?"  I wasn't aware when I had my install done that I would be paying about $500 for the equipment till after it had been put on. I am overall frustrated beyond belief thinking here I had security done for the betterment of my home insurance and that because I was "using" a company USAA recommends I was going to be getting a great deal and it would be a win win situation. Little did I know I would feel like I had been duped and double talked. I am not a happy customer at all. That said the install guy was great and nice I would just make sure YOU really NEED the security as I have found it may not be all it is cracked up to be and then you are stuck in a contract and hundreds of dollars invested.

"Protect America Alarm Systems are wireless home security systems that are so advanced and yet uncomplicated that the consumer can install all components to the system themselves. Tech support is provided which makes installation easy and very user friendly. The system is monitored and response to alarm signal is quick and nearly immediate. ( I accidentally set it off a couple times having forgotten that it was set when we left home). I've had a couple different systems in my homes over the years which were "professionally" installed; one was wired the other wireless. I install this myself with the help of tech support, I'm 65years old in good health but of course not as agile as I was a few years ago, but this system was a piece of cake for me to install. Every access to my home has been covered as well as some interior sensors. All of which have functioned flawlessly from day one!

Home Security Systems FAQs, answered by experts

It is possible to spend only $30 on a camera that can cover one particular area. You wouldn't need to buy software, hardware, cables, or anything else. Instead, it would connect wirelessly to an app on your phone where you could monitor the feed and take necessary actions at your own discretion.

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.

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.

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.

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.
