Techniques are generally described for controlling a camera to capture video based on one or more auxiliary motion sensors. First data indicative of motion may be received from a first motion sensor at a camera. In some examples, the first motion sensor may have a first field-of-view. Second data indicative of motion may be received from a second motion sensor at the camera device. In some examples, the second motion sensor may have a second field-of-view different than the first field-of-view. A determination may be made that the first data temporally corresponds to the second data. In some examples, an image sensor of the camera may capture first image data in response to the first data indicative of motion and the second data indicative of motion.

Auxiliary motion detector for video capture

A security network provides reduced power consumption and more robust communication of messages in comparison to conventional wireless systems. Reducing power consumption as discussed herein ensures that the security system is able to operate for a long duration of time, potentially with minimal or no power from an electrical grid. Additionally, redundant communication paths as discussed herein provide a more robust way of selectively forwarding security data to a remote server. The availability of multiple communication paths ensures that a respective remote target recipient such as a server resource or remote communication device operated by a user can be notified of a trigger event during power failure conditions, such as when certain communication functionality of a security system is disabled.

An image processing system receives a sequence of frames including a current input frame and a next input frame (the next input frame is captured subsequent in time with respect to capturing of the current input frame). The image processing system stores a previously outputted output frame. The previously outputted output frame is derived from previously processed input frames in the sequence. The image processing modifies the current input frame based on detected first motion and second motion. The first motion is detected based on an analysis of the current input frame with respect to the next input frame. The second motion is detected based on an analysis of the current input frame with respect to the previously outputted output frame. According to one configuration, the image processing system implements multi-sized analyzer windows to more precisely detect the first motion and second motion.

Image processing and motion compensation

Multi-window image processing and motion compensation

Video data is processed. A first high definition program stream is received that includes a first high definition video stream component. A first standard definition program stream is derived from the high definition program stream. A second standard definition is received having been derived from the first standard definition program stream. A second high definition program stream is derived from the second standard definition program stream and the first high definition video stream component.
