Hi,
I have changed my NVR from DS-7608NI-I2/8P to DS-7616NI-M2/16P because I needed more cameras. On the older I2 (with NVR 4.0) I used to view the live view with VCA info turned on (i.e. seeing the green/red boxes where any movements were happening). And that worked fine for the 6 cameras I...
I have the same issue with DS-KD8003-IME1. There is a constant noise coming out of the speaker. The firmware is the latest available in Europe 2.2.50.
Koen, did you somehow sort out your noisy unit?
