Hi @MrJus 

 

The main problem is that 12 meters is way too far for a regular USB-C cable (even an active one) to reliably deliver power. Data might make it to about 15 meters with an extender, but the 2 amps your camera needs won't hold up over that distance.

 

The fix is to ditch USB for power and use Power over Ethernet (PoE) instead. The camera still uses Wi-Fi for data, but we'll run power down a separate Ethernet cable, which is designed for long runs like this (up to 100 meters no problem).

 

 

Here's what you'll need for a 12-meter setup:

 

Ethernet cable (Cat5e or Cat6): Your 12-meter run—handles power without issues.

 

PoE injector: Plugs into the wall and adds power to the Ethernet cable.

 

PoE splitter: At the camera end, this pulls the power off the cable and outputs it as 5V through a USB-C port. (Make sure it’s 5V USB-C—most splitters are 12V or barrel plugs, which won’t work.)

 

Short USB-C cable: Use the original 4m one (or a shorter replacement) to connect from the splitter to the camera.

 

This keeps data on Wi-Fi and power stable over the full 12 meters.

 

Hope this helps.

I’m currently looking for a better-quality cable and came across this post. I’ve just purchased a 12-metre USB-A to USB-C cable, and it’s very unstable. Every time it switches to IR mode, an issue occurs and it keeps restarting. I’m now considering whether to add a waterproof junction box to extend the power supply, and then use a shorter USB cable. Please share the bandname or purchase link to me if you have good cable. Thank you.
