“We have used Alert Protective Services since we moved to the Chicago area in 2007. It is easy to speak to someone on the phone and they are immediately responsive in any event that the alarm is triggered. Representatives who come out to service the system are always professional and friendly. The alarm service is excellent.

We have also used their A/V team to install our built-in audio speakers and related equipment. I took off a star because our experience with the sales side of the business has been inconsistent. Ask for Fernando if you use the A/V services, he is responsive and cares about the quality of his work”. – Jessica Janicki
