My house was broken into the week of 11/30. I called Citywide Alarms and they responded quickly. I had a working alarm system installed in my house within a few days. The sales person and technicians were very professional and knowledgeable. The system is very user friendly and I absolutely love being able to use my smart phone to set and disable my house alarm remotely!!! I am very satisfied with Citywide Alarms and would highly recommend them to anyone in need of an Alarm system.

Impressed by their customer service 24/7. I would love to do business with them again. Btw, from now on, I would not miss any of the delivery because I have a new camera and I can unlock any door in my house using remote app from my phone. Yay

We have had Gateway Alarm Inc for 7 years and we have been very, very satisfied. They are always prompt in taking care of any problems. We always feel very secure with Gateway. Whenever we call, they answer promptly, plus they will take no chances. If they can't get in touch with us, they send out the police and fire departments so we feel very protected in their care. We would highly recommend Gateway Alarm, Inc.
