"Andrew Brown from Alarm Protection Group facilitated the installation of our home security system. He was a very helpful and informative, and was not pushy, as with other ADT sales reps. He followed up with us after the system was installed to see if we had any questions or concerns re the system. I highly recommend Andrew to anyone who is interested in a home security system."
