A security system and method for a restricted entrance such as a vehicle gate is disclosed where requests for entry are issued from a device such as a computer or smartphone and directed to a dispatch operator. The dispatch operator locates the position of the requested entrance and sends a request to a control computer that verifies the user's authority to enter. If the user is authorized for entry, the control computer sends a command to a gate opening device or other mechanical device to open or unlock the gate. The system can also be used with software running in background to automatically send a request for entry when the user is within a predefined distance from the gate using GPS technology or other means.
