A device includes a first housing and a second housing pivotably coupled to the first housing. The second housing has a first camera disposed on a first side of the first housing and a second camera disposed on a second side of the first housing. The first camera has a first field of view (FoV) that is adjustable via pivoting the second housing, and the second camera has a second FoV that is adjustable via pivoting the second housing. The second FoV is different than the first FoV. A privacy cover is coupled to the second housing and is configured to transition between a first position in which the first camera is unobstructed and a second position in which the first camera is obstructed.

Security camera device for vehicles

Systems and techniques are generally described for audio signal processing for motion detection. In some examples, a first energy level of a first audio signal detected by a first microphone is determined over a first period of time. In some further examples, a first change in the first energy level from a first energy level value to a second energy level value is determined during the first period of time. In some other examples, a determination is made that the first change in the first energy level exceeds a threshold change value associated with the first period of time. In at least some other examples, a bias of an audio amplifier of the first device is adjusted.
