Canary achieves its flat lens front with an extra sheet of glass that's not optically active. Buried inside is a conventionally shaped M12 security lens.

A switchable IR blocking filter is included for day/night mode. This blocks IR light during the day, but switches to be transparent at night.

The lens holder is unremarkable. Components are placed within the light chamber to allow the back to support the heat sink.

Note the empty holes for... some sort of sensor, not stuffed. Maybe air quality?

That's it. I hope you've enjoyed this tour into the insides of Canary.
