Excellent and timely new service! The technician, Eddie was on time, very nice, and knowledgeable about ARM Security System. He walked us through the entire installation from start to finish including testing the system. We were comfortable using the system when he left. I highly recommend ARM Security System.

The crew at ARM security in Reisterstown is by far the best security company I've worked with. I was so impressed with their work after installing alarm and cameras at my office that I had them install at my personal residence. Next I'll have them setup security for my rental properties. I highly recommend - you won't be disappointed.

We been using ARM security for some rental properties for more than 6 years now. In each case ARM gave us a great (unbeatable) deal for each property including free installation of a brand new wireless system covering 3 entry doors and 2 motion sensors with a great keypad and battery backup too. Monthly service fees are also competitive & reasonable and come with an initial 2 year contract with automatic annual renewal making it easy to manage.We were also glad to have ARM to professionally install a cell phone booster system.

My experience with ARM security has been great ! I have had service with them for 15 years and counting with two different houses. I've never had problems and if any updating of system was needed, the staff has always been helpful and made me a priority. Arm is locally owned and operated not like some of the "big" Alarm companies. Rates are competitive too.-Kevin
