I want to order these wifi-adapters https://aliexpress.ru/item/32971875623.html
What is the difference between 2 and 2.54mm? With a directional antenna there will be a range of about 2-3km?

These adapters have 2 pin rows in their layout, one with 2mm pin pitch, the other with 2.54mm. Only one of these seems to be placed in the different variants.

This sounds to be possible. However, you may consider to use an adapter with higher output power for the AirPi instead. So you wouldn`t need to point your directional antenna to the aircraft.

Thank you
Stephen is working on this. He likes to release things that work well. So probably 1 to 4 weeks is my guess

Hi
I have ordered and now received the little lan/adapters from aliexpress.
https://de.aliexpress.com/item/32957...3eec4c4d9z7hvV

At first: they work
But the connection description seems to be wrong. I had to swap USB D+ and D- to make it work.

I have tested them on RX with different Alfa on TX.
It all works and my former RSSI problems are no longer present.
Finally I want to use them on RX and TX

@RocketMouse,

The recommended IP Cameras are Hisilicon type board cameras.

I have used the Hi3516CV300 IMX291 and it looks good but, does not have WDR. The previous developer Vitaliy posted some flight video.
планерная гора (25 min 14 sec)



Also, another user tried Hi3516E & Hi3518.

IP board 1080p camera based on Hi3516E also working perfect with OpenHD (3 min 45 sec)

IP camera based on Hi3518 working with OpenHD (1 min 47 sec)


This is a hisilicon HI3516A with IMX291 sensor but, supposedly supports 50/60FPS...
*This would be ideal if it's actually correct because, higher FPS results in lower latency.

With Hi3516, 3518, 3519 etc... Just be sure to read all the specifications closely to match what you're looking for and maybe contact the seller.

**Example: Hi3516cv300 w/ Imx291 is considered one of the lower end type cameras it's actually the same one I have.

But, Hi3516A seems to be higher-end.

Aliexpress can be such a cluster fuk sometimes trying to find exactly what you're looking for in terms of information.

Overall, any IP camera from Hisilicon should work and, one of the larger versions with a high-quality zoom lens can easily be adapted for an inexpensive zoom UAV.

AS with most things, the more expensive cameras on there will probably have higher quality and performance but, if you just buy a $20 camera it should work good enough.

Htcohio, thank you for your answer. I agree that Ali web site is really annoying in any aspect.

I did some research and it looks like you are right - HI3516A is the one most expensive, but the only supports 60fps.

- Advanced Full-HD IP Camera Soc - Hi3516DV100
- Mainstream Full-HD IP Camera Soc (FHD 30fps):
Hi3516CV300 - 2-frame WDR, Tone mapping
Hi3516CV100/200 - DWDR, Max.2M Pixel
Hi3518EV200/201 - DWDR, Max.2M Pixel


Here is some data:
Hi3516A - H.264/H.265 @ [email protected] fps − [email protected]60 fps

Hi3516E V100 - H.264/H.265 @ 1920 x [email protected] fps + 720 x [email protected] fps
Hi3516E V200 - H.264/H.265 @ 1920 x [email protected] fps + 720 x [email protected] fps
Hi3516E V300

Hi3516C V200 - H.264 @ [email protected] fps
Hi3516C V300 - H.264/H.265 @ 1920 x [email protected]45 fps

Hi3516DV100 - H.264/H.265 @ 1920 x [email protected] fps + [email protected] fps
Hi3516D V300 - H.264/H.265 @ 1920 x [email protected] fps + [email protected] fps

Hi3518E V200 - H.264 @ [email protected] fps
Hi3518E V300 - H.264/H.265 @ 1920 x [email protected] fps + [email protected] fps

Best sensor is IMX307 2mp ( prev 291) or IMX335 fir 5mp.
