Longest possible Cable for Pi Camera and why?

Wed Jan 15, 2020 3:22 pm

The longest one is 600mm by Adafruit. Can you use buffers? like, another vcc and gnd to not loose power?

I've got those adapters that fruitoftheloom linked above. It worked for me with a 3m HDMI cable but distance is not guaranteed as the MIPI CSI-2 camera interface is only meant for short internal connections. The extra long ribbon cables like the one Adafruit is selling is out of spec as well.

Anything more than the supplied cable we cannot guarantee. The longer the cable the more prone to interference the signal will be, and because the signal is extremely fast, interference can cause rapid degradation of the image.

Some people have tried longer cables with success, but I would expect anything over 1m to be very unreliable, especially in electrically noisy environments.

That is 5m, but expensive, and not supported anyway.
Only supported is 15cm 15pin flat ribbon cable.

I do use 1m and 2m 15pin flat ribbon cables routinely without issues.
You get those for <2$ incl. shipping on aliexpress.com

Greatly thankful with the answers. does any of you have worked with multiplex the Camera port to for example, change one to other?

The Raspberry Pi supports only one MIPI CSI type camera (the kind using a flat ribbon cable). I saw one person assume the LCD display connector could also be used a camera connector since they both have 15 pins, but of course that not true. I am not sure, but maybe you are thinking about the 4-to-1 camera multiplexer from Arducam:

This is obviously an aftermarket hack. To my surprise, allegedly it sometimes works, but that's all I know. You can still only use one camera at a time, and I am not sure what application would be better off with that configuration, instead of simply using four separate R-Pi boards each with their own camera.

The Raspberry Compute modules allow to connect two cameras.

Not multiplex, but capture two cameras at once is possible with Arducam Stereo hat:

Maybe Multiplex wasn't the right word, I just want to have more than 1 camera (posibly 4) to one port and latching one to see the other, just having the signal of one camera at the time.
