Hi, I'm looking for a script/app that can run on PC/Mac that changes the day/night switching of cameras (R0s and G1) that are connected to an NVR. I would envisage one that has reference to local sunrise/sunset time then modifies the Scheduled times in the camera for switching and can be manually run every fortnight/month to change these times. Changing just the Scheduled times will allow any other setting differences that I currently have between day and night to be preserved. Don't have a computer that is continually on to allow the current suggestion to automatically do this so the current solutions are great but won't work for me. Hikvision this is an oversight that could be easily added to give better functioning of the cameras.
