Did you remove the film from the front of the cameras yet? Also, make sure the focus is set to auto-focus when adjusting the focal length. Sometimes by sharpness may adjust to "0" by default, however, the default value should be 50. Not sure if this may be a potential firmware issue.
Hello,
Got 6pcs of this camera and Dahua NVR from Andy, trying test everything but I have very blurry video. Everything is on default settings, trying to preview on Sony 4k tv connected with hdmi to nor, and also from Mac through Smart PSS. Tried different settings, different cables, different cameras.. same results. Am I missing something here?
