Housing of an image capturing device

An imaging unit, comprising:

• a housing that comprises an inner surface, wherein the inner surface of the housing defines a lens channel, and wherein the inner surface of the lens channel defines:
• a helical step that protrudes outwardly from the inner surface into the lens channel, wherein the helical step is angled at a first predetermined pitch;
• a first glue pocket, in the lens channel, which extends from the inner surface of the lens channel to a top surface of the housing;
• and
• a second glue pocket opposite to the first glue pocket, in the lens channel, which extends from the inner surface of the lens channel to a bottom surface of the housing, wherein the first glue pocket is at an offset from the second glue pocket along a first lateral axis of the housing based on the first predetermined pitch of the helical step.
