Overview
Arcules video search can be accessed through the icon in the lower right of any camera’s video player. Video search saves a lot of time when compared to using the playback scrub bar.
Default filters for video search are four hours ago if the user enters search from live. If the user enters search from playback, the search date/time will default to the playback date/time. The user can adjust date and time and, if she entered search through a View, change the camera as well. The user can also adjust the duration of the period in between thumbnails and the size of the thumbnails by using the sliders at the top.
The thumbnail video search results can be further refined with forensic filters available from the “more” icon at the top right of the search interface. A drawer will slide out with forensic filtering options,.
Filter by People or Vehicle
The user can filter by person, person wearing color, vehicle or vehicle of a specific color. To do so, switch the object filter on and select between the two options (people/vehicles).
Select a color to filter by color. Only one color per camera’s field of view is supported.
This object filter may be switched on and off in the drawer, retaining the settings already set by the user.
Filter by Area of Interest
The user can further refine their object search by switching on the area of interest filter and drawing a search area. Search results will only show objects detected within the user-defined area.
The area of interest filter may be switched on and off in the drawer, retaining the settings already set by the user.
To provide a larger viewing area, the user may close the search filters drawer. A small portion of it will remain visible at the right edge of the screen showing the person icon and its current filter state (on/off).
FAQs
Is Forensic Video Search available on Edge Gateways?
No. At this time, Forensic Video Search is only available for customers with Cloud subscriptions using Cloud Gateways.
How long is Forensics data kept for? How far back can I search?
Forensics data is kept as long as video data. So, if a camera has retention period set for 30 days, forensics data is kept for 30 days and a user can go back up to 30 days for a typical camera to search data.
Can I use Forensic Video Search with previously recorded video?
No. Forensic Search data starts being collected at the point where it's enabled for a camera channel.
Does forensics AI require a separate video stream?
No, it only requires one video stream. It infers on recorded video rather than live so if the recording is behind (for example, internet is down or b/w management is enabled) you won’t be able to perform search until the data has reached the cloud.
I see bounding boxes drawn around people and vehicles. How are bounding boxes drawn?
Bounding boxes are rectangles drawn over the object. For a person the bounding boxes will include a person from head to toe. For vehicles, the software attempts to draw a rectangle around the complete vehicle.
What objects are considered a vehicle in a Forensic Video Search?
A vehicle is 'bicycle', 'bus', 'car', 'motorcycle', or 'truck'.
What is the “Resemblance” setting?
The resemblance setting is a way a user may adjust the accuracy of the Forensic Video Search results. Setting resemblance may eliminate results which are occluded or have a low confidence level. Setting a lower resemblance level may allow results that include targets which the AI has less confidence in being the object class related to the search.
