Summary
If you are having difficulty getting clear live views under low light conditions with your Vandal
Proof IP Dome or the Fixed IP Dome, this is likely due to IR reflections inside the camera. To
solve the IR reflection problem, you can choose to disable the IR Light function if there is
sufficient lighting on the installation site. If you do not have enough lighting on the installation
site, proceed to identify the possible causes and adopt the solutions to reduce IR reflection
and improve the quality of live view.
