Herelink Ethernet Camera Routing Isuue. Cannot Ping Camera from Laptop, but can ping from Controller!

Hi @KFlucas937,

The Herelink supports Ethernet video input, and that’s the whole point of having an Ethernet port on the air unit.

You can have an RTSP video stream on the Herelink’s QGC when you connect an Ethernet camera.

With Siyi, you have to be careful because if you connect the Siyi camera directly to Herelink’s air unit using Ethernet, it will damage the air unit’s Ethernet PHY. You can use series capacitors, just as I did, to isolate the camera from the air unit, and it will work fine.
Cubepilot officially warns about this here:

SB_0000007 Ethernet on Herelink one a SIYI camera

Attention all SIYI camera users, please DO NOT connect a SIYI camera to HereLink ethernet directly, you MUST use magnetics or capacitors to isolate or put a switch or hub in line. We are unsure as to why, but it appears that the SIYI is destroying the HereLink ethernet port. We are not blaming SIYI, it is simply that some hardware’s do not play well together, and sometimes need something in the middle to help…

I was trying to make a custom software on my laptop to talk to the camera, and that’s why I needed to ping it from laptop. You might not need it at all.

Regarding video latency with Ethernet, the siyi FPV app on herelink works well, but has limited features. You can use the latest QGC for herelink (4.4.5 currently), and it should work fine.

Hope I have answered all your questions.

Thanks,
