1. A thermal-control system for a security camera, the thermal-control system comprising:
a first thermal-control subsystem, the first thermal-control subsystem configured to transfer a first quantity of heat to a housing, the first thermal-control subsystem including:
a first thermal interface material, the first thermal interface material located between a system-on-chip integrated circuit device and a first heat sink, the system-on-chip integrated circuit device mounted to a first surface of a first printed circuit board;
a second thermal interface material, the second thermal interface material located between a memory integrated circuit device and the first heat sink, the memory integrated circuit device mounted to the first surface of the first printed circuit board; and
a third thermal interface material, the third thermal interface material located between a second surface of the first printed circuit board and a second heat sink, the second surface of the first printed circuit board opposite the first surface of the first printed circuit board; and
a second thermal-control subsystem, the second thermal-control subsystem configured to transfer a second quantity of heat to the housing, the second thermal-control subsystem including:
a fourth thermal interface material, the fourth thermal interface material located between a second surface of a second printed circuit board and a heat spreader, the second surface of the second printed circuit board opposite a first surface of the second printed circuit board to which a passive infrared sensor integrated circuit device and an image sensor integrated circuit device are mounted.
