"It was nice to felt heard and understood when we contacted Alarm Protect Group. Our prior experiences with other security companies was horrible. You could either never get ahold of someone or they offered overly expensive options. Received a security system that was in our budget and wish we could have found Alarm Protect Group sooner."

"Recently bought a new house. I googled search for security companies and lightspeed came along. I was a little nervous at first as I have had difficult experiences with other companies. I was pleasantly surprised talking to the owner (Omar) . He was friendly and easy to talk to. He quickly resolved all my questions and my system was installed the next day. Installation was professionally done for a fair price and outstanding quality. 10 out of 10!"

Oh - the job costs were very reasonable for the work done. I will certainly call them back if/when I need additional alarm or security work."

"The work done was excellent. Wesley is very knowledgeable about all aspects of security cameras . He gave us very clear recommendations in which systems to use and then installed the cameras in a highly professional manner. Because he was upgrading an older camera existing system there were a few unexpected surprises he had to handle but he worked through and came up with great solutions for all of these issues and we now have a terrific product. He was also far more cost competitive than any of the larger camera companies. If I could give 6 stars I would."

"We love our surround system so much!! We moved into a home that was pre-wired… got a bid from Best Buy which was ridiculously high. They were trying to oversell systems we truly didn’t need. Kevin came and explained a system within our budget!! ?????"

FAQs for alarm or security system installation projects in Houston, TX

If you terminate your security system before your contract ends, you’ll likely have to pay a cancellation fee—often a percentage of the remaining contract balance. To avoid these fees, consider choosing a brand that offers contract-free plans, like SimpliSafe or Vivint. You can also negotiate with your provider to see if they provide pro-rated cancellation fees or special exceptions.

Paying for a security system is a valuable investment because it enhances your home’s safety and deters criminal activity. With millions of property crimes each year, having robust security measures helps protect your property and might even lower your insurance premiums. It's a worthwhile investment for lasting peace of mind.

The average cost to install security cameras ranges from $125 to $3,500, depending on the amount, type, and placement. To install a complete setup of four cameras, homeowners can expect to invest an average of $1,300 for labor and equipment. Installing multiple cameras gives you comprehensive coverage of vulnerable entry points and enhances overall property security.
