Last update: April 2021
This article describes how to display the inclined objects horizontally on the images by adjusting the inclination (YAW) angle in the below multi-sensor cameras, using sample images from a camera installed on the wall.
Applicable models:
WV-X8571N / WV-S8531N
Optional brackets for wall mounting:
- Wall mount bracket WV-QWL501-W (i-PRO white)
- Mount Bracket WV-QSR502A-W (i-PRO white)

Installation example #1 - horizontal + downward layout
1. Installation condition of WV-X8571N / WV-S8531N :
- Cam.1, 2 and 3 are arranged horizontally / Camera 4 is tilted downward (horizontal + downward layout)
- Installation height of the camera is 3 meter
- The camera is installed on the building wall as shown in Figure 1 below
2. Before inclination (YAW) angle adjustment
The target object (road in this example) is tilted in Cam.1 and Cam.3 images as shown in the below red lines.
3. After inclination (YAW) angle adjustment
The target object (road in this example) above the center of the screen can be displayed horizontally as shown in the below red line.
