The very first webcam was set up to monitor a coffee pot.

Quick Scoop: What Did the First Webcam Monitor?

In the early 1990s at the University of Cambridge’s Computer Laboratory, researchers pointed a camera at a communal coffee pot in the “Trojan Room.” They were tired of walking over only to find the pot empty, so they rigged up a simple black‑and‑white camera that took low‑resolution images of the pot several times a minute and shared them over the network.

That feed became famous as the “Trojan Room coffee pot” and is widely recognized as the first true webcam: its entire job was to let people check if there was fresh coffee without leaving their desks.
