Full support for all types of dewarped video stream output from fisheye cameras with
in-camera dewarping capability.
 NVR’s software algorithm can perfectly corrects the original fisheye images, generating 6
specific fisheye view modes from User’s usual perspective.
 Based on user’s instant request for changing view mode or PTZ view point, NVR server will
process the original fisheye image and respond to the client individually. In this way, what a
client sees on Live View will not affect playback, recording, as well as another concurrent
connection.
The virtualized ePTZ manipulation also allows User to dynamically explore any region of
interest within the hemispheric view like operating a genuine PTZ device .
To make use of NVR’s dewarping features for your fisheye cameras, please
1. Adjust Video Quality Settings
After the fisheye camera is successfully added, go to Setup page Devices tab, select the
device and then Video tab, make sure you set the Stream Mode as “FISHEYE” for a
hemispheric camera ( KCM-3911, KCM-7911) .This is to make sure this hemispheric camera
is outputting fisheye original video stream as a mini fisheye dome camera does.
2. Adjust Fisheye Display Settings
Select your Mounting Type, and then Default Fisheye Mode. For a Fisheye Mode containing
panorama view, you may want to configure the Default Rotate X (width of view) and Default
Rotate Y (height of view) configurations.
You may adjust the dewarped area by clicking “Image Calibration”. In the edit mode, move or
resize the red ring to define the dewarped area, and then click “Set” to save the setting.
