Gun-mounted recording device

Abstract

In an exemplary embodiment, a gun-mounted recording device comprises a housing configured to be mounted to a gun, a recording module arranged within the housing, the recording module comprising a first electrical contact, and a power supply configured to be detachably coupled to the housing. The power source comprises a second electrical contact. The first electrical contact and the second electrical contact are configured to contact each other and form a circuit when the power source is coupled to the housing in order for the power source to supply power to the recording module. The first electrical contact, the second electrical contact, or both are configured to move in response to relative movement between the power source and the housing when the power source is coupled to the housing, in order to maintain the supply of power from the power source to the recording module.
