“Sacred Heart University has been working with the Mercury Group Company for several years. We have an excellent working relationship with the Security System Manger Lou Kresmery and his technicians. His staff members are always available to answer any questions. The Mercury Group staff members are always professional, helpful and responsive. I have been in the security industry for over 20 years and this company has outperformed all other surveillance companies.”
“Mercury Security has partnered with our district to assure that we transitioned our antiquated camera system to the best state of the art system that our budget would allow, keeping in mind future technologies and changes. They have been outstanding communicators and have always been flexible in their scheduling to meet our needs. Our districts expectations from Mercury Security has been exceeded and their technicians have been a true pleasure to work with.”
“I’ve been working with Mercury Security since our original system was installed over 10 years ago and am very happy with the service. Mercury is very easy to work with, they explain things so you understand them and are always there in a pinch. Excellent customer service and response time from the company. If I have a problem, that I cannot resolve myself, I just call Mercury Security and they are right on top of things, 95% of the time they’re out the same day.”
