Is a Pen (in A Cup Or On A Desk) a hidden camera?

Usually not. Here's the specific thing that separates an innocent one from one worth a second look.

Why it's usually nothing

A pen sitting in a cup or on a desk is the most ordinary object in a rental, which is exactly why a pen-camera is built to look identical to a normal pen.

The tell that actually matters

A pen camera is usually slightly thicker than a real pen and the "clip" often conceals the lens — check for a tiny dot near the clip or the very top of the cap. The tell that matters most is placement: a pen propped upright and aimed at the room rather than lying flat or clipped to a notepad is doing a job other than writing.

The power check

Battery-only, no cable to check — judge this one purely on the lens dot and the angle it’s propped at.

This is one object out of the full 90-second sweep. If anything here is positive, run the flashlight lens pass on it before doing anything else.
