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
