Utilizing Multiple RPIs as Cameras and Hub

Mon Sep 06, 2021 10:45 pm

So I'm hoping for some direction from those more experienced than myself. I've been a huge RPI fan for years. I'm currently utilizing an OG RPI B+ as a PiHole on my home network, as well as an RPI 3B+ running Retropie, wired in with a Mausberry ignition circuit, acting as a mobile media center in my conversion van.

I'm looking to install 4x (possibly more) cameras in my van (dash, rear view, driver/front passenger, passenger cabin, etc), with the feeds being recorded to an external HDD. From reading other posts regarding multiple camera setups, I am aware of the RPI's limitations when it comes to processing multiple cameras feeds simultaneously, so I am thinking of using an individual RPI (maybe a Zero) to run each camera, and then have the feeds run into a hub unit (I'm thinking an 8GB RPI 4B) to organize, store, and provide user access to the recorded feeds. My goal is to utilize the recordings to produce a Family Travel Blog/Vlog. I know the storage requirements for 4+ constant video feeds will not be minimal, so I would likely figure out a way to dump the accumulated footage each night to cloud storage or another PC for editing and production purposes.

My problem is I have no idea where to even begin this build. I haven't been able to find anyone who has done anything resembling what I'm trying to do, and I'm getting really overwhelmed trying to find projects that others have posted that I can Frankenstein together into a working system. I think one of my main problems may even be that I just don't know what to search for.

If anyone could provide some advice, or direct me to camera and/or hub projects that they think might help, I would be eternally grateful.

MotionEye OS would be a good place to start.
My home system uses a combo of MotionEye and Pikrelllcam OS Pi's.
Use old PiB/B+ at each camera, backup to networked Pi with WD purple drive in external powered caddy.
Been working for 6 years.

Zero's in USB gadget mode?
Zero's can compress the video to h264/MJPEG, saving some bandwidth.
Have not tried that.
USB cables might be ok for the shorter distances.

MotionEye OS can use webcams.
I got a dozen of old PS3 Eyecams for $2 each :D
Only 640x480 but bigger pixels so a bit better in low light but with more noise.

Thank you. Low cost is definitely one of my goals and that could definitely help.
