A229 pro and plus rear cameras must have their own processor.
It is possible that rear cameras such as t130 have separate software.
Therefore, double-sided type-c may not be a standard type-c for the update.
In addition, one end of the cable of the IR supported interior camera is type-C, the other end is a 3.5 mm jack input.
That is, the microphone input is the input location of the third camera.
As far as I understand, the power to the camera can only be connected from the top, the GPS part.
This will be more suitable for hk3 type-c. Of course, since hk4 is also L type, it is suitable for use with cables running sideways.
It looks like the inner camera has 4 IR lights and a light sensor. This means that it will work more stable in automatic IR mode. This means that the problem of misleading the camera as a result of IR lights hitting the ceiling or the back of the mirror and coming back to the camera will be eliminated.
