The 2.0 megapixel domes adopt a 1 / 2.5 inch progressive scanning CMOS sensor with a built-in 10X optical zoom lens, providing users with a high-definition, high frame rate and high signal to noise (SNR) real-time image acquisition system. Users can view and control H.264/M-JPEG dual encoded HD video, up to 1920 x 1080, and support three video streams, dual H.264 and scalable M-JPEG.
