I think I narrowed the issue down.

As mentioned the cable works fine, I connected the Laptop and I get an IP from the router and I am connected to the internet.

I have about 10 Mbit/s up and downstream tested with Google and Ookla Speedtest. Also the camera work via a 2 meter LAN cable on the same port, but not on the 15 meter one.

So my assumption is at the moment that the signal is not strong enough for the IP camera to be recognized. However, this camera should only need 4mbps

 

Formula for bandwidth:

Bandwidth (Mbps)=Resolution (MP)×Compression Rate×Frame Rate\text{Bandwidth (Mbps)} = \text{Resolution (MP)} \times \text{Compression Rate} \times \text{Frame Rate}Bandwidth (Mbps)=Resolution (MP)×Compression Rate×Frame Rate

Using the average compression rate for H.264:

• For a low-motion environment, the compression rate might be closer to 0.1 Mbps per megapixel.
• For high-motion or complex scenes, it could go up to 0.3 Mbps per megapixel.

Calculation:

1. Low motion (0.1 Mbps per megapixel):

   3.7 MP×0.1 Mbps×30 FPS=1.11 Mbps3.7 \, \text{MP} \times 0.1 \, \text{Mbps} \times 30 \, \text{FPS} = 1.11 \, \text{Mbps}3.7MP×0.1Mbps×30FPS=1.11Mbps

2. High motion (0.3 Mbps per megapixel):

   3.7 MP×0.3 Mbps×30 FPS=3.33 Mbps3.7 \, \text{MP} \times 0.3 \, \text{Mbps} \times 30 \, \text{FPS} = 3.33 \, \text{Mbps}3.7MP×0.3Mbps×30FPS=3.33Mbps

Conclusion:

• For low motion, the camera will need about 1.1 Mbps.
• For high motion, the camera will need about 3.3 Mbps.

Sadly no limitation in bandwidth nor ethernet cable lenght is specified. This makes the camera useless to me and I will claim a warranty refund.
