Why is the picture blurry?

Oct-15 2019

Answer:

1. If it is the resolution problem, please kindly check whether it is the best resolution

2. If it is the lens quality problem, please kindly check whether there is any damage in lens, or whether there is fog, dust or other things which block light.

3. If it failed to focalize, please kindly try to adjust the lens or localize again, if there is no result, please kindly try to adjust the back focus ring.

4. If it is the first time to install the device please kindly check the lens interface. If it is a lens with C type mounting base, C/CS lens adapter ring should be used.
