4K Ultra HD
HD and megapixel network cameras
Axis offers a comprehensive portfolio of 4K Ultra HD, HDTV- and megapixel network cameras.
Combining HD/megapixel network cameras with a selection of non-megapixel network cameras that are optimized for other needs (such as powerful optical zoom, extreme light sensitivity or low cost) creates video surveillance installations that are effective, reliable and cost-efficient.
HDTV has experienced enormous success the past years, driven by the consumer electronics market and its shift from CRT-based television sets to LCD- and plasma-based TV screens. 4K Ultra HD is now starting to be adopted by the consumer market in the video surveillance arena it promises outstanding image quality and details.
4K Ultra HD provides up to four times higher resolution than standard HDTV 1080p resolution. 4K Ultra HD uses the 16:9 format. Defined by SMPTE (Society of Motion Picture and Television Engineers), the most important standard is SMPTE ST 2036-1UHDTV.
SMPTE ST 2036-1UHDTV Defines a resolution of 3840x2160 pixels with high color fidelity in a 16:9 format using progressive scanning at 25/30 Hertz (Hz)—which corresponds to 25 or 30 frames per second, depending on the country—and 50/60 Hz (50/60 fps).
A camera that complies with the SMPTE standards indicates adherence to 4K Ultra HD quality and should provide all the benefits of 4K Ultra HD in resolution, color fidelity and frame rate.
4K Ultra HD is based on square pixels—similar to computer screens, so 4K Ultra HD video from network video products can be shown on either HDTV screens or standard computer monitors. With progressive scan 4K Ultra HD video, no conversion or deinterlacing technique needs to be applied when the video is to be processed by a computer or displayed on a computer screen.
