Fisheye Camera Dewarping Option
With hemispherical lenses, fisheye cameras generate images at up to 360-degree width,
which can cover all four corners of a room or both sides of a long aisle. As the original image
captured by wide-angle lens is much distorted, to suit most monitoring purposes, the
Dewarping process is required to alter the uneven lines and shapes before the images are
displayed. On Live View screen, ERC is able to dewarp the live image to whichever fisheye
mode the fisheye camera supports.
On a fisheye channel, right- click on the image, select “Fisheye Mode” and then the desired
fisheye mode.
