Access control is the only proactive security measure you can choose, unless you are willing to pay for a guard at each secure door! Obviously, that is neither feasible, nor practical. Video and intrusion systems are fine additions to a security system, but they are purely reactive, providing images of a crime in process, or recording a crime that has taken place. They do little or nothing to prevent the event.
With a Keri Access Control System, you can prevent a crime before it starts by keeping unauthorized people out. Would you rather have a video of the crime or would you rather stop it from happening? It’s like having a security guard that never gets bored or falls asleep on the job and doesn’t require a monthly paycheck.
