When selecting the adapter current, it should be based on the maximum operating current of the device.
If there is a direct label, you can follow the current test required in the equipment manual;
If only the working power of the equipment is marked in the equipment manual, the working current of the equipment can be converted according to the formula:
I (current) = P (power)/U (voltage)

Tips
When the camera is switching (day/night) mode, the instantaneous maximum power will be greater than the power of the device in normal operation. At this time, when converting the working current, you need to calculate the maximum power marked by the device.

The following table shows the fluorite C3C parameter specification table, and the current is:

I= 7 (ICR switching instantaneous power consumption) / 12 (voltage) ≈ 0.58 (A).
