Deactivate night vision (IR) on Hikam S5
Using the Hikam S5 with the Synology surveillance station was leading to many false positives. These false positives occur when the the camera was switching between day and nights visions.
As there is any software solution to deactivate the night vision mod on the Hikam S5, we’ll do a simple hardware modification.
First step, remove the back cover (4 screws) :
