Embedded based tailgating/piggybacking detection security system

Access control is a system which enables the authority to control and restrict access to a target sensitive or secured area. However, its effectiveness is highly dependent on the proper usage of the system by those who are granted access. These authorized personnel have total control of the door from the time it unlocks until it relocks again. One of the biggest weaknesses of automated access control is the lacked of a system to prevent a practice known as “tailgating” or “piggybacking”. This paper presents a low cost solution to this problem by using a single internet protocol camera and an embedded based control unit combining with video analytics technology. Results showed that the developed system is able to detect various tailgating/piggybacking violations successfully.
