How alarms are generated from the video analysis of cameras

By exploiting the use and processing of large data sets, called "metadata", the video analysis systems produce automatic alarms starting from the video sequences on cameras , allowing, through image analysis, to alert in real time the Police or the persons in charge if something significant is detected.

The information collected through metadata, in fact, can be used to report people, cars, animals and other objects detected in the video, analyzing their appearance or the movements they make inside the area shot by the cameras .

Based on the parameters set, the video analysis system is able to evaluate which actions are "appropriate" with respect to the programming set and which are "anomalous", promptly sending an alarm to the control panel.

 Practical example of video analysis with alarm system

 Wanting to provide a practical example of this, let's imagine we want to detect the entrances to a building with a gate at the entrance.

 In this case, the action detected by the cameras that should be considered "anomalous" could be that of a "person climbing over" the gate instead of turning it on normally with a key or ringing a bell and waiting for authorization. In this case the video analysis system would monitor the accesses of all the subjects passing through that gate and filmed by the cameras, sending alarms in the event that a figure, corresponding to a person, is detected, who try to climb over that gate without accessing it normally and moving abnormally.

 The functionality of the video analysis systems therefore makes the video surveillance system much more sophisticated and avant-garde than a traditional system, making it one with the alarm system and increasing the overall security level of a structure.

 In addition to the detection of "anomalous" movements, the usefulness of the video analysis can also be seen as regards:

 Abandonment of objects left stationary in an area; especially useful application for the safety of public and crowded places such as railway stations, airports etc.

 Counting of people or cars passing through a certain area, useful for optimizing the flow of roads;

Surveillance purpose: the analysis software "photographs" the area to be monitored and constantly checks it with the images it detects every moment.
