Usually, IP cameras should provide URL from which you can access the raw camera feed and if you can open the URL and see the feed in VideoLAN VLC Media Player (https://www.videolan.org/vlc/index.html) the same URL can be used in libVLC to access the feed programmatically.
Face Tracking
How many faces can be tracked simultaneously?
The maximum number of faces that can be tracked simultaneously is internally limited to 20 for performance reasons.
Using VisageFeaturesDetector, any number of faces can be detected in an image.
How far from the camera can the face be tracked?
The tracking distance depends on the camera resolution. For example, for a webcam with resolution 1920×1080 (Logitech C920), tracker can be configured to detect and track faces up to ~7.25 meters from the camera (with performance tradeoff).
Face tracking does not work as I expected
Our face tracking algorithm is among the best available, but like all Computer Vision algorithms it has its limits related to image quality, light conditions, occlusions or specific reasons such as head pose.
If you notice specific issues or have special requirements, you may send us your test video footage and any specific requests, and we will process it and send you back the tracking results. This may allow us to fine-tune the tracker configuration to your specific requirements and send you the best possible results.
