I have now ordered 4 of these cameras in as see total over 3 seperate orders. all cameras i have operate over a 16 port POE switch. The cameras provide excellent images in the day and night. They are able to zoom in upto 150 metres away as seen in the 2nd image below. In nightmode i can see images clearly upto 70 metres away (1st pic below) with the camera having both short and longe range IR leds which light up based on the level of zoom. The audio i would rate at 7/10 but this is likely due to the codecs being used. I found the microphone captures quite a bit of internal noise and clicking when the camera is moved via PTZ but is fine when the camera is idle. I did experience an electronic hum / interference through the speakers but this is likely due to other electrical circuits and not the cameras. Maybe better electronics shielding of internal components may help with this. The cameras have an auto tracking feature which is useful and effective. I highly recommend these cameras
