Jump to Event Print Email
The "Jump to Event" capability takes information retrieval to a new level of sophistication. In most video analysis systems it is possible to retrieve information based on the fact that an alarm occurred at a certain time. One can usually perform the retrieval based on the time of the event. (In more traditional Digital Video Recording Systems (DVR's) no events are generated and hence one has to scroll through the entire footage to find an event). In simpler systems a couple of images may be retrieved showing the moments just before and just after the event.

In slightly more sophisticated systems a whole video can be viewed before and after the event. All this is very simple when the event is something that happens at a fixed point in time such as a person jumping over a fence. The user can note the moment that this event occurs and store footage from just before and just after this event. This is referred to as Jump to Alarm and virtually all systems can provide this capability.
Jump to Event
If the event takes place over an extended period of time, the requirements for Jump to Event can become very complex. For instance, if a bag is abandoned in a crowded scene with a detection time of 10 minutes, the bag has been identified as abandoned and an alarm is triggered by the system after 10 minutes. If the user looks at the video for 30 seconds before and after the alarm, the bag would be seen but without a history of how it got there. iOmniscient developed a Jump to Event capability associated with an iQ 140 level non motion detection system that goes way beyond this. It enables the user to jump back to a pre-defined time before the event started. Hence in our example of the abandoned bag, at the press of a button the user can jump back in time not just before the bag was detected but before it was first brought into the scene and abandoned. The user can immediately review both the event and the preceding period of video footage and gain important information on who brought the bag in and the person's current location if he is still within camera view.Now consider a scene where there might be ten suspicious bags in the area being viewed. The Jump to Event function should enable the user to click on any one of these bags and "jump back" to the moment when that particular bag was brought into the scene and abandoned.

The user then has the option of archiving the event for later review or discarding the alarm information.
None of the simpler data storage and retrieval systems has such a capability as it is very dependent on the intelligence required to find the bag in the first place. Only a system that can operate at the iQ 140 level and above can actually have a sophisticated Jump to Event function similar to the one described here.
