Megapixel Lenses
Sharpness and Detail for IP Cameras
Megapixel cameras (IP, AHD, CVI, TVI) with high resolutions (Full HD, 2MP, 4MP, 5MP, 4K) require special lenses that are able to transfer such a large amount of detail to the sensor.
Megapixel Lenses are intended specifically for use in IP and analog HD cameras. Using a standard lens (intended for analog SD cameras) in a high-resolution camera would result in a blurred, out-of-focus image.
