Mega Dome’s main innovation lies in the fact that it makes possible to use 1600*1200 resolution combined with PTZ movement: autofocus and backlight management of images coming from a moving camera, mechanical and electrical issues, all those harsh difficulties to face when merging megapixel resolution video with fast and accurate PTZ movement have been settled.
March Networks MegaDome is also the first-megapixel PTZ dome to apply MPEG4 compression algorithm on high-resolution video (it has a 1600*1200 pixels resolution – 2 megapixels). The outcome is that, though the dome is still delivering high-quality video at a very fluid frame rate (15 fps at maximum quality and resolution), MPEG4 compression allows terrific savings in bandwidth and storage requirements: the compression of high-resolution video is 10 to 20 times more effective (depending on the monitoring scale) that standard megapixel compression technologies on the market, all JPEG based.
With this megapixel PTZ dome you can take advantage of both high-resolution video (image quality and detail, vital help in post-event reconstruction thanks to digital zoom) enhanced by 16x optical zoom and fast and accurate PTZ movement.
MPEG4 compression on high-resolution video allows implementing March Networks Mega Dome into real-world IP installations when there usually are many cameras connected to storage servers or to monitors over IP. In a similar situation, the overall bandwidth and storage required by JPEG compression make the desired installation not feasible or extremely expensive.
Customers needing to perform high-quality video surveillance may not always have the luxury of a multi-gigabit connection to the network so MPEG4 Main Profile algorithm provides huge savings. The March Networks Mega Dome allows building high-resolution video surveillance IP systems in a very cost-effective way. Thanks to those systems, this video security environment will provide performance and video surveillance accuracy unmatched up to this moment.
