H2 – Security Consoles and Booths with Guards
Security Consoles and Booths are a great way to start off your commercial security system. If you are located in Denver and searching for alarm companies, you should consider putting Security Grade’s access control security system in place, then a security guard can monitor access through a security console or booth station located at the entrance of a facility. Through ID badges and proximity readers, guards can be positive that they are allowing only approved personnel and visitors into the appropriate areas.
