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)


Read the following manuals carefully before installation:
- Installation Guide
- Additional Information "How to adjust the angle of view"
  *Those manuals can be downloaded at Documentation Database

 

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.
