A Pi camera module is a compact camera sensor accessory made for Raspberry Pi systems. It connects directly to the board and lets a small computer capture still images or video without needing a full-sized USB webcam. In maker projects, it is often paired with a display, buttons, and battery power to create a portable device.
In cyber security, this matters because tiny, low-power cameras are useful in both defense and misuse. Defenders may use them for physical monitoring, device inspection, and prototypes that document or automate a workspace. Attackers can also use similar modules in covert hardware, building hidden cameras or reconnaissance tools to observe screens, people, or equipment. The security impact depends less on the sensor itself than on how it is powered, mounted, and controlled.
