Abstract: A method for, in a map of background objects, registering presence of a stationary object exhibiting motion at a location in a scene monitored by a radar detector comprising detecting over time radar echoes at a radar detector monitoring a scene. The moving object is one of a true moving object or a stationary object exhibiting motion. The over time detected radar echoes are evaluated for finding a stationary object exhibiting motion. The presence of the stationary object exhibiting motion is registered at a location, corresponding to the location of the stationary object exhibiting motion, in a map of background objects. A method for detecting moving objects using a radar detector is also presented wherein the map of background objects is used as input.

Abstract: A video capturing device configured to capture video data, the image capturing device comprising: an image processing pipeline configured to generate a video stream from the captured video data; an encryption key activating module configured to, upon request, activate an encryption key and deactivate any previously activated encryption key used for encrypting the video stream, such that only one encryption key is activated to be used for encryption of the video stream at each instance in time; an encryption scheduler module configured to, at a predetermined time interval, instruct the encryption key activating module to activate an encryption key; an event handling module configured to, as a response to receiving indications of a detected event, instruct the encryption key activating module to activate an encryption key; an encryption module configured to encrypt the video stream using the one activated encryption key.
