N4S/N4 Pro S, N5S, and S1PM all use different rear camera USB wires, so the rear wiring is not compatible across cameras unless you wire things with the cable that came with the S1PM camera.
The N4S and N4 Pro S have the smallest data stream to the main cameras. These cameras share the very same 2.5k rear camera.
The N5S has a dual rear camera (2.5K rear external + 1K rear cabin), so there are TWO data streams that travel to the main camera.
The S1 Pro Max has a 4k rear camera, so it has the highest data rate that needs to travel to the front camera.
The cable for each of these cameras features a DIFFERENT physical construction. At a minimum, the level and quality of shielding increases with each camera. There is a measurable difference in cable diameter for each of these cables. The N4S/N4 Pro S has the least amount of shielding (thinnest diameter), the S1PM features the greatest amount of shielding (thickest diameter). Not sure if wire gauges differ, I haven't cut these cables to make a complete physical inspection.
If you run wires for the N4S, you are likely to run into issues at some point if you subsequently use that same cable with the N5S or the S1PM cameras. The video feed has greater potential for corruption.
If you run the rear USB cable that came with the S1PM camera, it should work fine for all other cameras (so far).
Elsewhere, people have made the claim that "all USB-C cables are the same." This is demonstrably not correct.
