In some cases, when you start the camera-based calibration, this message appears:
“The projection surface could not be identified. If this is intended, push the NEXT button. Otherwise, click on the BACK button and adjust the camera.”
The reason for this issue is in the misoperation of the camera.
- Camera image is too dark to detect any projection. Re-adjust the camera. Check here for how to adjust the camera.
- IDS camera works on 100 Mbits/s. Control of the network adapter, and switches and hubs are 1Gbits/s compatible. Check the cable for the 1Gbit/s compatibility. Note that sometimes broken ports or cables can continue to work, but drop the bandwidth from 1000 to 100 Mbits/s. Read here for how to configure an IDS camera.
