Anti Tailgating is to be used as feature for eliminating certain crimes. An unauthorized entry of the person to any location with aid of the authorised person or by illicit method is called as tailgating. As a rule of thumb, only one person is allowed to enter the site using authorization code which can be used for proximity card, face recognition or fingerprint access, but if the follower takes advantage of the entry made by an authorised person, then it is referred to as tailgating.
Sometimes referred to as piggybacking, tailgating is a major cause of workplace theft and vandalism as entry gained by the un-authorised person leads to many criminal acts. This mode of illegal entry needs to be restrained and restricted in order to eliminate the crimes, improve the security & reduce other undesired episodes which may arise.
Nundnet turnstiles & access controls are equipped with the anti tailgating sensors hence the threat level is reduced to zero which assures the guarantee of safe & secure site.
The tailgater usually gains access by three methods
· Tailgater watches for an opportunity that once an authorized person crosses the door, and he jumps in a very short period of time and crosses the door hence enters the site
· Sometimes an authorized person keeps a door open as a form of help or aid to a person who does not have access to the site.
· The tailgater walk-in the crowd and seeks entry once the guard diverts.
The tailgating can be stopped by various methods but in general we do add the tailgate detection sensor beams in the turnstile. Once the authorised person seeks an access to premises, the door opens and the person walks as usual crossing the tailgating sensor and enters the premises. The gate remains open for the set period of time, and in the same period of time if a person crosses the tailgate sensor again while the gate is open; the tailgate sensor creates a pulse for alarm hence alerts the security or concerned supervisor. The alerts generated can be in the form of Audio or Visual or both. The door opening logic works in synchronization with the tailgate sensor.
The use of anti-tailgating option along with the anti passes back feature helps in improving the security of premises without fail.
