"We have our second home in the mountain so they were able to send it and he was able to work with our installers and it worked out fine. So far we were are pleased with it. We were with another security system for 12 years and we changed because their selection of product was of a higher grade. They are excellent."

"Protect America provided me with the best equipment and home security in the industry.  Believe me I have called around for weeks trying to find the best deal and value.  After I signed up with Protect America and received the equipment and installed it, I finally had the peace of mind I needed as a mom of two teens that stay home for 3 hours before I get home.  I get a text on my cellphone when they get home and I know if it is my son or my daughter who entered the code (they each have their own).  That is AWESOME, and if the kids forget to set the alarm I can do it from work on my cellphone app.  I don't understand the complaints about  the equipment, every single piece of equipment I received did what it's supposed to.   I am VERY HAPPY and will commander them to all my friends and family and you!

"I communicated with Rob Calbo for services of a background check with CSI Secure Solutions and he was fantastic.
He spoke with me in a very professional manner and put me at ease right away.
The process was seamless and my request was delivered very efficiently. Within just a few hours of providing them with information, I was able to get feedback. Rob took the time to speak with me and answered all of my questions. 
I will definitely be using them again in the future should the need arise, and I would definitely recommend them as being very efficient, professional and reliable.

"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!"
