Setup

Stabilize a shaky image with Electronic Image Stabilization (EIS)
Electronic Image Stabilization (EIS) can be used in environments where the product is mounted in an exposed location and subject to
vibrations, for example, wind or passing traffic. Turn on EIS to get a smoother and steadier image without blur.
EIS also reduces the file size of the compressed image and lowers the bitrate of the video stream.
Note
When EIS is turned on the image is cropped slightly, lowering the maximum resolution.
1. Go to Settings > Image > Image correction.
2. Turn on EIS.
Compensate for barrel distortion
Barrel distortion is a phenomenon where straight lines appear increasingly bent closer to the edges of the frame. A wide field of view
often creates barrel distortion in an image. Barrel distortion correction compensates for this distortion.
Note
Barrel distortion correction affects the image resolution and field of view.
1. Go to Settings > Image > Image correction.
2. Turn on Barrel distortion correction (BDC).
3. Set the level of correction that gives you the best image.
Improve license plate recognition
To better recognize the license plate of a car passing by the camera, you can apply and adjust a number of things.
One option is to use the pixel counter in your camera to set the optimal pixel resolution:
1. Go to Settings > System > Orientation and click
2. Adjust the size and placement of the rectangle in the camera's live view around the area of interest, for example
where the license plates of passing cars are expected to appear. You can then see the number of pixels represented by
the sides of the rectangle.
