I've always wanted them at the front so that when pulling out of a side road they can see both directions along the road I'm joining and the rear camera can see back down the road I'm leaving - complete coverage of all the other vehicles.since they'd be mounted more towards the rear of the vehicle).
4 separate cables (three remote cameras + power) coming out of the front windscreen mounted unit might be a bit too much!For a 4CH system, do you think 4 remote lens is also good option?
can do the same quality as current 2 channel, memory cards are a consideration of sorts, no problem if you stick with good quality cards, the bigger issue is finding a workable side camera solution, too much variation and too labour intensive for aftermarket systems, would be much easier to do as an OEM fitout, I can't see 4 channel being a mass market option, very small niche DIY marketBut what of bitrate and FPS? Those matter in image quality. Then there's the SD card- how much can it handle and what type would you need? I think there's some market out there for a decent 4-channel if it performs well at a good price. But most are quite happy with 2-channel cams.
This is the ideal position for my side cameras - the glass dome in the centre of the bonnet, it has a great view in front and to the sides, can see down the road both ways when pulling out of a side road, doesn't suffer reflections of the dash off the windscreen. Front and side views are all in one unit so only needs one cable installed, it could even record a cabin view if its rear sensor had a CPL...Concept gadgets do not impress me much...
