Indoor flying - ambient light?

[USDrone]

The only time I have the opportunity to fly the Tello indoors is in the evening. I always get a warning about there not being enough ambient light. I turn on all the lights and still get the warning. Is this typical for the Tello with artificial lighting?
Does it need a lot of natural lighting?
Thanks!

It is typical of tello, VPS needs a good dose of light to function well ..
