Arecont Vision of Glendale, Calif., announces the domestic debut of four H.264 MegaDome cameras. Available in color or day/night versions and with 1.3-, 2-, 3- or 5-megapixel sensors, the dome cameras incorporate H.264 (MPEG 4, Part 10) compression that uses an average of up to 10 times less bandwidth and storage compared to megapixel counterparts using MJPEG compression. Each model (AV1355, AV2155, AV3155 and AV5155) features 360-degree pan and 90-degree tilt adjustment for accurate positioning, and an integrated 4-10mm megapixel varifocal lens. The MegaDome cameras also offer user-selectable full or ¼ resolution for either live viewing or archiving. The MegaDome series simultaneously supports H.264 and MJPEG at full frame rates. Multi-streaming provides up to eight concurrent non-identical streams with variable frame rates, bit rates, resolutions and picture quality. Real-time streaming protocol (RTSP) allows compatibility with media players such as Apple QuickTime, Windows Media Player, VLC Player and others.
