Lux from camera

[andre__x]

Hi all!
Is there a way to get the illuminance of an ambient from a Dahua camera?
I need to turn on some lights in the evening, but only when it gets dark and I don't have an external light sensor.
Thanks!

Not that I'm aware of. I think it would be easier to buy a photocell.

110v to 220v:

Outdoor Hard-Wired Post Eye Light Control with Photocell Light Sensor, 120-277VAC 50/60Hz, Dusk to Dawn Light Sensor, photocell Sensor for Outdoor Light (cUL Listed)-2 Pack

Low voltage:

Photocell Switch, Mini Light Switching Sensor Remote Photocell Dusk to Till Dawn, with Automatic Illumination Detection Circuit, 8-50V DC Wide Voltage LED Automatic Control Switch

Gotcha. There are people who are far more knowledgeable than I who can come up with a solution. Through the Dahua API, you may be able to find a proper trigger.
