Before you start:

QVR Pro supports most standard fisheye cameras available in the market. It includes the Qdewarp technology to convert distorted parts of original images into proportional ratios. QVR Pro allows you to view a single fisheye camera’s image from up to nine simultaneous channels and from different angles. It also allows cross-platform hardware-accelerated decoding for fisheye camera images. QVR Pro ensures higher surveillance performance for greater security, while providing deployment flexibility.
