Masking a detected object in a video stream

A camera for masking a detected object in a video stream captured by the camera, the camera comprising:

• circuitry configured to execute, when the camera is arranged in a camera system including the camera and at least a further device, wherein a location and field of view is known for the further device and a location and a field of view is known for the camera, and wherein the field of view of the further device and the field of view of the camera are non-overlapping;
• an obtaining function configured to obtain information indicating that an object is approaching the field of view of the camera, wherein the obtained information is determined from information from the further device indicating a location and a direction of movement of the object and the known locations and fields of view of the camera and the further device;
• a reducing function configured to, in response to the obtained information, reduce a threshold on a confidence level over which an object is determined to belong to an object class which is to be masked in the video stream;
• a detecting function configured to detect an object and determining that the object belongs to the object class that is to be masked in the video stream in response to a confidence level of the object belonging to the object class that is to be masked being over the reduced threshold;
• and
• an inserting function configured to insert masking of the detected object in the video stream, wherein the masking is such that the object can no longer be identified after masking.
