Astronomic time settings for automatic day night changes with sunrise and sunset

[camcam]

I have some lights on a timer which has an "astronomic" setting so the lights automatically turn on and off with the sun.

I have a few of the Dahua HDB4300C cameras and I set them to change settings with the sunrise and sunset so they will work at night. The problem is that the sun rises and sets a minute or two more or less every day so you have to change these setting regularly and with multiple cameras this is a bit tedious to make these changes as often as necessary. Is there a way to make these changes astronomic?

I am wondering why this valuable feature is not an option in the camera settings or is it and I can't figure it out.

I flip it externally at sunrise/sunset via Domoticz: https://www.ipcamtalk.com/showthread.php/8960-Switch-Dahua-Day-Night-Profile-via-IPC-HTTP-API

its not built into the camera, the embedded storage on these cameras is quite small.. its amazing they fit all they do on em really.

I also wrote a NodeJS module that can switch profiles if you can code: https://github.com/nayrnet/node-dahua-api and it would work great with this NodeJS module also: https://github.com/mourner/suncalc

I've got a python script I run every couple of days. Can update a standalone camera or an nvr.

I've just cleaned it up and added to github https://github.com/psyciknz/Dahua-RiseSet
