I have a Pi Noir camera module and it all seems to work OK except for constant interference on the picture in the form of horizontal flashes
This makes it useless for motion detection, as the interference triggers the frame change
It's not a uniform thing, it seems random and the best I can liken it to is a bad TV reception.
An example of the output attached (apologies it is a still not a moving image - but you should get an idea what I mean)
I'm thinking i may just have a faulty camera board
