On some new Dahua and Kbvision brand HD Analog video recorders today, if you find that the image obtained from the Camera is blurred, not as clear as before. , follow this article with me to fix the problem.

- Dahua: XVR1B04-I, XVR1B08-I, XVR5104HS-I3, XVR5108HS-I3, …
- Kbvison: KX-7104Ai, KX-7108Ai, KX-DAi8104H3, KX- DAI8108H3, …
