Is a Clock Radio 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

Functionally identical to the alarm-clock entry above, but worth its own line because clock-radios often have a speaker grille that’s easy to mistake for a camera opening, and vice versa.

The tell that actually matters

Speaker grilles are a pattern of many small identical holes. A single larger hole, or one hole set apart from the grille pattern, is the thing to flag. As with the alarm clock, check that the "front" faces you and the display, not the bed.

The power check

Always plugged in — not a useful signal on its own for this object.

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.
