Device Usage while accessing the Network-Camera)

Andreas Czech

Hi,

 

I need your Help with my CPU-Usage.

Situation (normally):

CPU Usage around 5-10%

my Problem is -> when I access my Network-Camera (Axis M1125-E) using the Webinterface, the CPU-Usage goes to 90-100%.

I created an Exception in the Web Filtering, Advanced Threat Protection, Intrusion Prevention. Although tried DNAT/SNAT Rule but nothing helps. Maybe I've missed something/configured something incorrect. Maybe you have an Idea what could be the Cause/and how to solve it.

Thanks in Advance

 

attached the Screenshot of my IPS Log:

192.168.131.170 is my Computer and 192.168.41.126 is the Network Camera

    I'd start by disabling web protection and all the sub tabs under intrusion protection (global, attack patterns, antiflooding, etc..).  Access your camera.  In shell, execute top, which will show you what is consuming cpu.

    Start adding each disabled function back one at a time.  Once you've determined the culprit focus on creating the proper exception or bypass. A systematic approach helps narrow it down too many variables confusing things.

    the CPU Consumption is still 55-60%

    the CPU Consumption is still 25-30%

    maybe it's somehow related to NAT?

    Don't you want "Internal (DMZ) (Network)" instead of "Internal (DMZ) (Address)" in your Exception?  Did that make any difference?

    added Internal (DMZ) (Network)" + "Internal (DMZ) (Address)" to the Exceptions.

    the CPU-Usage is again around 95% (95-100%)

    what's with the Thought an NAT Rule would help?
