Hello,
my zm (with 4 camera) work very well but I have a little problem.
My 4 camera are 640x480 and actually are in zm set to 320x240.
If I set one camera to 640x480, all camera become red in zm-console, instead if I use only one camera with 640x480 it work.
But I want 640x480 for all my camera.....any idea?

I have already tried to increase shmmax, shmall but not enough!
thank you

EDITç
I find this in log

i would think if you can succesfully capture at 320x240, you need to change your ip cam to suit, or your using a webcam that doesnt like higher than 320x240 or ..... we need a little more info mate

make sure your shmmax and shmall is set to more than 147456000

If you happen to be using a capture card like a BT878 with a single chip handling 4 camera's... all cameras need to be the same setting/resolution to work correctly.
