Optics setting. When you connect a 220x360 degree lens to an IP camera, the picture is transmitted blurry. Filter problem?

Question

Iron

We screw on a 220x360 lens instead of an IP camera lens, but the picture is blurry. What is the problem?

Answer 1

Wrong focal length.

Answer 2

Without a brand of camera and lens, this is guesswork.
There was a similar situation when there were threaded adapters on the camera and lens. You screw it in, and the image is blurry on a varifocal lens. Removed the adapters - everything is clear. The whole problem was that the back of the lens barely reached the matrix.
