I'm used to integrating onvif devices/rtsp streams on nx, can i also use the onboard camera of a jetson or pi, directly on nx?

Anybody that tried this before?

A setup like this:

Hi Stefaan,

I have been testing this for a while both on Jetson Nano and Raspberry Pi 3 using this
excelent guide:

https://support.networkoptix.com/hc/en-us/articles/360033842053-ARM-Single-Board-Computer-SBC-Support-Installation-Instructions

I have installed the NX server on the Jetson/RPI and then merged this server with my "normal"
server and the camera comes up by it self as any other IP camera.

One issue I have with this is that it comes up with 3 or 4 cameras but only one of them is the actual camera, the other ones are marked as not connected.
Probably some adjustment I havent found yet.

Anyway, it works like a charm :)

I have also tried to use a Raspberry Pi Zero W and installed the server on raspian lite but I didnt figure out how to
install the dependencies.

Best Regards

Torgrim Johansen

Hello,

> One issue I have with this is that it comes up with 3 or 4 cameras but only one of them is the actual camera,

This issue is going to be fixed in the nearest release or its hotfix.

Ok, nice :)

Do you know how we install the mentioned "additional dependencies called 'cifs-utils'." in the tutorial?

```
 sudo apt install cifs-utils
```

Torgrim Johansen i see nothing in that article from Norman Graafsma to add the camera from the jetson to the nx server

i know how to connect the jetson hardware to nx, i have already done several integration but i cannot find an easy way to integrate the 'onboard' camera

probably something simple that i'm overlooking

If you install the NX server also on your Jetson then the camera will automatically appear in NX.

Are you using the Jetson as your main NX server?

yes, i have done several developments with nx and jetson, i have never seen my jetson camera show, maybe i need a manual activation somewhere, i have now a jetson nano system with nx on it and the camera is not showing

Are you using Jetson nano with Raspberry PI camera v2?

How do you open the camera image?
