Good afternoon everybody,
perhaps somebody can help me.
I changed to Raspberry pi 4 with raspbian and zoneminder 1.32.3 and got a Problem I never had.
I am working with 2 equal cams (Foscam FI 9826W), but only 1 cam is working. They are ok, because I get an image from both in another tool. Sometime the first is working, sometimes the other.
I tried VLans, Groups, different ports, it does not work.
Has anybody an idea?
Thanks a lot.
Kind regards.

2 equal cams
Re: 2 equal cams
I thought I saw you get an answer to this in another board (cross-posting's frowned upon, BTW), but the answer is probably that you don't have enough shm (shared memory) for the number and size of frames configured for both cameras.
Switch both -- in both ZM and the camera -- to 640x480 by maybe 5fps, and see what happens.
Then bump up a bit at a time.
Unless it's a 2 or 4GB Pi4, you may have trouble.

Re: 2 equal cams
Thank you very much. It's a 4GB PI. I will try it after my holidays and post an answer.
Kind regards.

Dear Baylink,
I have tried as you said, and it was working for a few minutes. Perhaps the shared Memory is near a border?
I will try to increase the max_framebuffers on the pi.
Thanks a lot.
Kind regards.
