Customer Testimonials

In 2020, our logistics firm moved into a new warehouse facility near Edmonton, Alberta. Once again, we reached out to Union Alarm. Their team installed new Card Readers and Electrified Door Locks to restrict access through our perimeter doors. Next, they installed a state-of-the-art Surveillance System with IP Cameras located throughout the warehouse. In 2021, we further entrusted Union Alarm to upgrade the security systems in our Kelowna facilities. We highly recommend this alarm company to secure facilities across Canada.
