Separation systems, tailgating and piggybacking detection devices, and related computer program products for controlling access to a restricted area and related methods

A separation system for allowing single authorized entrance through a passage to control entrance into a restricted area of a facility, the separation system comprising:

• a. a lockable turnstile comprising a rotary panel assembly that rotates to permit the passing of a user through an entry way when authorized;
• b. a turnstile controller coupled to the lockable turnstile to control the rotation of the rotary panel assembly to permit passage of a user through the lockable turnstile;
• c. a piggybacking detection device in operable communication with the turnstile controller such that the piggybacking detection device provides instructions to the turnstile controller to control the rotation of the rotary panel assembly to permit passage of a user through the lockable turnstile,
• d. the piggybacking detection device comprising a sensor configured and positioned for detecting the presence of one or more users within a counter area in the lockable turnstile before the entry way,
• e. one or more processors configured to receive a signal from the sensor regarding the presence of one or more users, and
• f. memory storing instructions that when executed by the one or more processors cause the system to perform operations comprising:
• i. upon receiving an access granted signal, unlocking the lockable turnstile for an entry time period to permit the user to rotate a rotary panel assembly of the lockable turnstile to enter the restricted area;
• ii. sensing a number of users in a count area within the lockable turnstile while the lockable turnstile is unlocked;
• iii. resetting the piggybacking detection device and locking the lockable turnstile after only the single user is detected in the counter area and the rotary panel assembly of the lockable turnstile is rotated to a position in the lockable turnstile in which the single user is allowed to enter the restricted area;
• iv. sensing, using a sensor in the piggybacking detection device, a presence of a single user within a detection area of the lockable turnstile;
• and
• v. upon receiving the access granted signal and sensing the user leaving the detection area and not entering the count area, locking the lockable turnstile to prevent rotation of the rotary panel assembly of the lockable turnstile and prevent passage into the restricted area and resetting the piggybacking detection device.
