Abstract
A sensor device, a holster sensing system, and a video-recording system are provided. The sensor device includes a control unit and a sensing module. The sensing module includes a reference coil set and an induction coil set that are arranged in a stacked structure. The sensing device is fixed on a holster. The induction coil set is configured to be adjacent to the holster. The control unit determines whether a gun is in the holster according to an inductance change between a sensing value generated by the induction coil set and a reference level provided by the reference coil set. In an application of the video-recording system, the control unit transmits a trigger signal to a recording device if the gun is determined to be pulled out of the holster according to the inductance change, so that the recording device is activated to start recording.
