To the entire staff at Sentinal Lockout, on behalf our company, we want to acknowledge you for your superior service. Over the last 10 months we have been in contact and have hired your firm for various jobs. Since implementing your surveillance system, we have been able to monitor live activity at the building, "clean sweep" the building of problem tenants, control / deter vandalism, and monitored illegal subletting. Additionally, the local Police Dept was able to monitor the building from a remote location. Your staff was accountable, courteous, prompt, knowledgeable, and honest. During any problem we encountered with the technology, you easily addressed it. Your sales rep, installer, billing dept, and computer technician we a pleasure to work with. Thanks again for everything.
