Hi ....
I have a Cisco switch 2960 24-port with 20 camera connected it
Sometimes camera images are displayed in black. (in NVR)
While the Ping connection is in place
What causes this problem?
There is a way to see the drop packets? (without using monitoring equipment)
Thank you for help and guidance

Hello,
from what I can find in the manuals, it looks like the cameras use port 80 by default. You could try and use a less common port, since 80 is used for a lot of Internet browsing traffic...
