  • the guardian only has to look at one display device, such as a monitor screen video, and he can immediately see what's going on, who sent an opening call. Therefore, during the short exit blocking delay, for example 8 seconds, he can see what is happening at this exit and decide whether to intervene, for example by triggering the second delay.
  • the exit control device further comprises a video processing module which deletes certain image areas and replaces them with messages without overlapping.

  • guard station and this opening request triggers the launch of a short time delay during which the issue remains locked.
  • the guardian present at the guard station can intervene by condemning the opening of the exit considered and launching a second delay of greater duration.

  • the guard can then, from the guard station, order the rearming of the locking member and the issue is then locked when it returns to the closed position. If the goalkeeper does not intervene, the issue considered remains unlocked.
  • the actuation of the unlocking member triggers in the zone of the exit considered, at the same time as the launching of the first time delay, a signaling indicating to the public that the exit will be unlocked very quickly.
  • Detection of. opening request triggers a first time delay To, a signal to the public and an indication to the guardian.
