Double image phenomenon on fixed dome cameras

Last update: June, 2021

A fixed dome camera may display a double image depending on the vertical (TILT) angle, due to the curvature of its dome cover. This phenomenon occurs when the camera direction is nearly horizontal.

 

Occurrence condition 

When the vertical (TILT) angle is approx. 70 degrees or higher (C-B in the below picture)

 

Countermeasure

Adjust the vertical (TILT) angle to lower than 70 degrees (B-A in the below picture)

Position of camera lens
