GHS security systems [& my sales rep Ernie] installed a burglar alarm in my house and I am very pleased with it. The few times I have had to contact them the customer service was outstanding. Their product is just as good if not better than the bigger companies, with all the same “bells & whistles” and the installation came out perfect. The salesman was a real gentleman who educated me without pressuring me to buy. I do believe you get more and pay far less with this company…Thank you & good luck!
