Premier says the new cameras “prodive up to 25 times greater compression than MPEG versions” and “provide major savings on the required bandwidth needed to stream high-resolution pictures”.
Comprised of four models offering 1.3, 2, 3 and 5 megapixels, the new line features Arecont Vision’s proprietary H.264 compression technology. The new megapixel cameras support multi-streaming capabilities for the transmission of several H.264 video streams at different video formats, frame rates, and/or resolutions.
The new camera line was developed by applying the company’s world-class expertise in the field of FPGA-based hardware image processing. The resulting proprietary H.264 encoder implemented on a single FPGA delivers 80 billion operations per second, a feat that would require 25 Pentium computers.
The compression improvement – the stream size reduction – with high video resolution is up to 25 times greater than conventional MJPEG compression when capturing a typical street surveillance scene with moving vehicles and people, Premier says. As a result, a high-quality 3 megapixel video stream at 20fps can be as low as 2 Mbps.
Images from Arecont’s megapixel cameras can be scaled to 1920 x 1080, or 1280 x 720 resolution with a 16 x 9 aspect ratio for a High Definition format. Up to four virtual cameras can be streamed by selecting regions of interest within the image and acquiring them independently. Resolution is fully controllable making it possible to stream full resolution or less in order to conserve bandwidth. It is also possible to stream the full field of view at a lower resolution while streaming regions of interest at full megapixel density.
