ABSTRACT:
A method and system for controlling the speed of security gate depending on its length is disclosed. It includes a system for determining the length of a gate that the system is working with and which automatically sets the speed of movement of the gate based on length. The system works automatically so that human intervention is not necessary to set the optimal speed once installed.
