This document describes techniques directed to a modular floodlight system with supplemental motion detection. The modular floodlight system includes a camera unit magnetically coupled to an accessory unit. The accessory unit includes passive infrared, PIR, sensors that expand and supplement motion-detection capabilities of the camera unit. For example, the accessory unit PIR sensor provides a PIR field of view, FOV, that is different than the PIR FOV of the camera unit's PIR sensor. Motion detected in either or both of the PIR FOVs is used to cause of change in functionality of the camera system such as, for example, activating image capture by the camera unit and/or activating one or more lights on the modular floodlight system.
