CERASTES VIRAN V8-02 Mini 5K EIS camera. Now it's Good!

My previous review on this camera left a lot to be desired in the audio department. The remedy was to turn off the Audio Noise Reduction in the camera menu .I was not aware of this feature ,as it¬ shown in the phone app and the manual sent with the camera was for a different model. The video was improved by cleaning the lens with isopropyl alcohol. Now this a good price for a camera with so many features.
