The outer ring has lenses to focus IR light, and a hole for the camera lens. The six infrared LEDs are on a thick board, with an aluminum heat spreader, and a connection to two solid metal blocks attached to the sensor board.
Optical Chain
  • The outer ring has lenses to focus IR light, and a hole for the camera lens.

  • The six infrared LEDs are on a thick board, with an aluminum heat spreader, and a connection to two solid metal blocks attached to the sensor board.

  • The lens is manually focused and secured with what looks like hot melt glue (this may cause focus issues over time).

  • There is just one piece of filter glass, flipped in place for day mode (higher end cameras use separate glass for day and night mode).

  • The optical sensor is at the bottom of the stack. It's surrounded by a clear plastic sticker (if you know why, post in the comments!).
