The "Sneeky Rats" representing your Multi-camera setup project wiring, "RATS NEST" style. (Also used by most of the similar projects).
There are FOUR "Sneeky Rats" representing, (@ MORE;) "Complex Technical issues", in your Multi-camera setup project.
Two of those "FAT" and "Sneeky Rats" are now beaning feed on your hard earned euros/dollars.
ALSO, Note, the comment on "...too much interference...".
H-H's, "50 cents per foot solution", regarding the "too much interference from ... the (chinese one ... (
)".
@ Mr. Google "...Apart from Tungsten ( foil) Copper has the second highest rate of EMI and RFI rejection, I would suggest Copper ( foil)..."
@ Mr. eBay "...Single-sided Conductive Adhesive Copper Foil EMI Shield Tape..." (eBay item number: 141074247289)
"...A MUST HAVE FOR ELIMINATING ELECTRICAL HUM AND NOISE. COPPER FOIL EMI (ELECTROMAGNETIC INTERFERENCE)..."
@ H-H I think that there is, at least, FOUR basic causes of "...too much interference..."
One the absence of proper filtering in the "CHEAP" Switching Power Supplies.
Another is lack of lack of "Foil EMI Shield Tape" on Camera Power Supply Cables.
The third is the absence of proper filtering in your home made battery power adapters. (i.e "HIGH BATTERY INTERNAL RESISTANCE".)
The USB Hubs and Cables are just the Innocent Victim's of EMI noise as per some previous post's on this subject.
Last but not least is those, "Sneeky Rats", see above.
@ H-H "...Congratulations! You have just proven exactly what I was trying to tell you..." and for your "GOOD WORK", "SO FARRRRR" !!!.
BUT.....to be continued, comments anyone.
PS; DON'T THROW AWAY THE ORIGINAL CABLES AND HUBS !!!.
Happy Hacking from H-H
