Abstract

Methods, devices, and systems for monitoring using a movable video device. The video device is movable to a plurality of positions definable by three dimensions. In an example method, the video device is moved to one of the plurality of positions. Within the video device, video data is acquired at the one of the plurality of positions. Further, within the video device, the acquired video data is processed using a processing algorithm that is configured according to a predetermined profile associated with the one of the plurality of positions. The result of the processing is sent to an external receiving device.
