PTZ camera causing my blue iris to shutdown

[jelf4352]

Hi,

I have a ptz camera on its own switch and 7 cameras on another switch. All connected to my windows pc that runs windows 10 and blue iris server. I’ve noticed the ptz camera causing blue iris cpu usage to spike when it detects movement and sometimes the video signal can be lost from this camera. Once the signal is lost , all the other cameras on the other witch start losing signal or blue iris shutdowns completely .

I’m not sure what to do here, any advice? My ptz camera is a Dahua ordered from andy ($800)

Server specs such as CPU model, memory, etc. ?
Camera settings such as encoder type, resolution, frame rate, frame interval ?
Did you optimize CPU usage as here? => Optimizing Blue Iris's CPU Usage
Are you using sub streams as here? => Sub Stream Guide
Did you try disabling HA ?

Hi Tony,

Thanks for the suggestions - i have all the optimizations and sub streams already running on blue iris. Also, HA is off.

I think it may be due to AI or the switch i purchased.

See attached for PC specs and Camera information. Also, uploaded my AI settings and switch i purchased.

Could be the switch. I have seen that with cheaper switches.

What is the computer - like i number and CPU generation?

You need to probably also pick a model to use for AI. Right now you have it blank, so it is running all of them and that can kill a CPU and crash it.

What is the BI log saying for AI make times?

PC Specs attached.
Processor Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz, 3192 Mhz, 6 Core(s), 12 Logical Processor(s)


Thanks, good catch. I just updated the AI model. Should I also only tick the box for "apply to motion triggers only"?. Does that mean its currently scanning all the time for AI?

OK that should be more than sufficient machine for that load.

I would check that apply to motion triggers only box as well. That isn't the issue, but hopefully cutting down on the number of models it runs gets you stable.

Do you have recommendation on a good switch? i don't know why, but i think that's the reason. whenever the PTZ has to move i hear the PCs fan screaming.

You mentioned AI make time. Where do i find that? see attached for screenshot of log.

To rule the switch out, first turn off AI on the camera and see what happens.

You are showing in the BI log AI Alert Nothing found 3xxms. The ms is the make time. That seems a little high for nothing found, but that isn't the cause of the issue. If it were 15,000ms then maybe we have an issue.

Many folks here trust Netgear switches.

Thanks, I can try doing that. The only thing is this problem happens rarely but enough for concern. I experienced it twice over the past month.

That brand of switch has proven to be unreliable.
Netgear Pro Safe switch's have never failed me.
