Our company recently retained the services of Sentinel to provide security and monitoring for our Dallas warehouse. Donny on the Sentinel team was our Technician and systems expert and provided exceptional service and subject matter expertise. Donny's work and Sentinel's dispatch service couldn't have come at a better time as shortly after our system installation we had an attempted break in. Our alarm system and notifications from Sentinel's best in class dispatch center prevented our business from having any losses and kept our inventory safe. I'm very pleased with Donny and the entire Sentinel team!
