Anti-tailing AB-Door



  Data Indexing successfully developed the high-performance and high-accuracy AB-Door anti-tailing detector by adopting the advanced intelligent video analysis algorithm. This product's high quality and high security are achieved by the combination with the advanced finger vein authentication and AB-Door control technology, which is able to meet the demands of all sorts of customers.


  When getting applied, the AB-Door product should be deployed at important passages. It will conduct anti-tailing detection in the region between two doors (door A and door B). When the system discovers two or more people entering the region, it will give the alarm and inform the AB-Door control system to take corresponding actions.

  Synchronous open in emergency
   When accidents suddenly occur, for example the fire, the system can implement the function of synchronous open in emergency which is to open the two doors (door A and door B) simultaneously and form an opening passage to facilitate the fire fighting.
