peepholes
Tiny viewing openings
Peepholes are small holes that allow you to see through a barrier without being seen yourself.
The most common is the peephole in a door, letting you view who's outside before opening: She checked the peephole before answering.
Any small opening that permits surveillance qualifies—in walls, fences, or enclosures.
