Hi
@Malcs
The judder is likely to do with shutter speed/exposure time, the ColorVu cameras by default are set to a slow 1/12 exposure time to allow more light into the sensor for better colour images at night but this slow speed also causes motion blur. If you go into the camera image settings you can increase the shutter speed to something between 1/12 and 1/25, but it will be a bit of trial and error because the faster you go with the shutter speed the darker the image will become.
In regards to the Mic, please check that you have done the steps mentioned in the below forum post:
There is a small selection of Hikvision cameras that support some sort of audio - audio I/O, built-in mic, 2-way audio - but on multiple occasions, customers have come back to us saying they are getting no audio on live view or playback. So to avoid this problem in the future we are creating...
