Modular floodlight system with supplemental motion detection

A camera system comprising:

• a camera unit including:
• an image sensor configured to capture images of a scene;
• and
• a camera unit passive infrared (PIR) sensor having a camera unit field of view (FOV) extending from the camera system;
• an accessory unit magnetically coupled with the camera unit, the accessory unit including an accessory unit PIR sensor arranged to have an accessory unit FOV extending from the camera system that is different than and which supplements the camera unit FOV of the camera unit PIR sensor;
• and
• a processing unit configured to:
• receive sensor readings from the accessory unit PIR sensor and the camera unit PIR sensor;
• detect motion within at least one of the accessory unit FOV or the camera unit FOV based on the received sensor readings;
• and
• cause a change in functionality of the camera system in response to detecting motion within at least one of the accessory unit FOV or the camera unit FOV.
