MC-A81: Anjoy 8MP IP camera module with a SigmaStar SSC378DE SoC and a
  SmartSens SC830AI sensor.

Chip and memory
- SoC is SSC378DE, which "looks like I6C replacement for SSC337DE".
  (https://t.me/c/1166652144/73971, https://t.me/c/1809358416/217588)
- It is a SigmaStar board, not HiSilicon: "A81 uses SigmaStar SoC, not
  HiSi". (https://t.me/c/1166652144/128486)

Sensor
- Sensor is the SC830AI (8MP, 1.5 µm pixel size).

Disagreements
- SoC: one 2024-01 message says "MC-A81 (8 MP SSC377/SC830AI)"; Tino's other
  messages say SSC378DE (once just "SSC378").
