You need 48v phantom power.
See link 2
And a few diodes for protection
I would drop the gain and put a second stage in with a pot to set the levels
You could up the input Z but 1 k should be fine.
That is about right for the first stage but maybe drop the two100k resistors to 22 k and put a bit more gain in a second stage or just use the microphone input on the camera as second stage
This should do 48v with a few mods
