To disable the IR LEDs (IR Lights) on a Hikvision camera but still allow it to go into night mode (black and white) follow these steps.
NOTE: these settings and menus can change anytime by Hikvision after a firmware update. Below we show two different menus and locations. If yours is in a different location, please let us know. This should help as a guide to be able to find this setting if it is different in yours.
How to turn of IR LEDs - try looking for these settings in the web GUI:
Configuration -> System (Advanced Configuration if it's an option) -> Service tab -> uncheck "Enable IR Light" and click Save
Configuration -> System -> Maintenance -> System Service -> uncheck "Enable IR Light" and click Save
