In PTZ camera (KCM-8111 and KCM-8211), they support digital zooming. When the camera reaches the most-tele position of the optical zoom lens, the ISP switches to the digital zoom mode if digital zoom function was enabled. The camera keeps zoom-in the interested objects. Of course, the image quality will be getting poor as the camera reaches higher digital zoom ratio.
If user wants to keep good image quality during zooming, turn off digital zoom function might be an option.Bu default, the digital zoom function is disabled if the PTZ camera supports this function.
