To look for fragments with a sought person, use button located in the lower part of the frame with this person. This will open Cross-camera tracking master window.

On Camera selection tab, select the cameras to perform the search on.

If the camera is present on a site plan, on the right side of the page the plan will be shown on the camera highlighted on it.

If the camera is not located on any plan, as well as when the plans are not used, a corresponding warning will be displayed on the right side. The search will be performed on this camera, but the route fragments found will not be displayed on the plans.

After selecting the cameras, go to Object Selection tab by pressing the button with the same name or clicking on the tab’s header. This tab will show fragments with the sought object within ±2 minutes from the first fragment. It is required to tick only those fragments where the sought person is shown, because similar-looking people may also be in the list.

After ticking all the fragments with the sought person, you can click on No more matches? link in the lower part of the page. The more precise search will be performed based on the ticked samples within the current timeframe. If such samples are found, they will be displayed on the object selection page.

To change search interval, use arrow buttons on the timeline.

To view all the confirmed samples, use View button.

After selecting samples, go to View result tab pressing the button with the same name or clicking on the tab header. The video fragments with the sought object will be sequentially displayed on this tab.

The conventional trajectory of the sought object will be displayed for cameras placed on the plans.
