Pin-hole on the side of Pro 4 camera

[Angier21]

Does anyone know what the small pin-hole is on the side of the Pro 4 camera, when it is out of the housing? Arlo support was less than helpful and said it was just a design of the camera, but it does not seem like it is just a design feature.

This is likely for disassembling the camera. Do you have a screenshot by chance?

This is just designed for disassembly. You don't need to worry about this section : )
