Physical access control options include traditional lock-and-key, on-premise (computer) solutions and cloud-based solutions.
Lock-and-key is the basic level of security technology requiring metal keys that match each lock in your building.
An on-premise solution is an electronic version of the lock-and-key, with the lock controlled by a computer server located inside the business.
A cloud-based solution can secure and control multiple locations from a browser or mobile device, revoke credentials when needed and view live or recorded video from any facility, regardless of location.
