Claim 18:
19. A method of assembling a camera, the method comprising:
obtaining a rear housing, the rear housing comprising:
an internal cavity;
a first interface surface surrounding the internal cavity;
one or more mounting formations;
one or more keying formations;
one or more retention formations; and
a connector receptacle;

obtaining a circuit board, the circuit board comprising:
an imager;
a printed circuit board (PCB) interface; and
one or more infrared (IR) emitters;

mounting the circuit board to the internal cavity to form a sensor subassembly, such that:
the mounting formations support the circuit board within the internal cavity;
the keying formations align the circuit board to the rear housing;
the retention formations fix the circuit board to the mounting formations; and
the PCB interface is aligned with the connector receptacle;

obtaining a lens holder that functions as a front housing, the lens holder comprising:
a second interface surface that is profiled to mate with the first interface surface;
a lens receptacle; and
an IR transmitting material;

obtaining a lens;
inserting the lens into the lens receptacle to form an optical subassembly;
disposing an ultraviolet (UV) curable adhesive to at least one of the first interface surface or the second interface surface;
combining the sensor subassembly with the optical subassembly such that the first interface surface is proximate the second interface surface;
aligning the lens to the imager via an alignment and focusing jig that creates relative movement between the optical subassembly and the sensor subassembly such that light from the lens is focused on the imager; and
curing the UV curable adhesive via UV light to secure and seal the optical subassembly to the sensor subassembly.
