MC-J30: Anjoy 4MP IP camera module with a SigmaStar SSC377 (64MB DDR2) whose
  stock firmware drives an SP4329 sensor, although it is sold as SC450AI.

Chip and memory
- SoC is the SSC377 (I6C, CA35) with 64MB DDR2.
  (https://t.me/c/1166652144/73003)
- A 2024-06 kernel log shows "Memory: 32588K/38720K available"; Tino: "377
  with 64Mb RAM (not E, QE)". (https://t.me/c/1166652144/117255)

Sensor
- Measured: the stock firmware loads sp4329_MIPI.ko, i.e. an SP4329 4MP
  sensor. (https://t.me/c/1166652144/79715, https://t.me/c/1166652144/83831,
  https://t.me/c/1166652144/119657)
- Tino said the module "can't magically change sp4329 sensor to SC or IMX".

Quirks and fixes
- The J30 is sold as SC450AI but ships an SP4329; "Anjoy doesn't usually do
  this. this is almost an isolated case." (https://t.me/c/1166652144/117282,

Variants, aliases and products built on it
- Applies to both MC-J30 and MT-J30: "M{C,T}-J30 - SSC377 / SP4329 (4MP)".

Disagreements
- Sensor: in 2023-09 Tino listed the MC-J30/40 with an SC450AI sensor; from
  2023-10 the stock firmware loads sp4329_MIPI.ko (measured).

Catalogue comparison
- The catalogue lists SC450X; Tino's evidence above gives SP4329
