I have tried to use use modern phones as dedicated webcams. The power consumption of constant video capture, compression, and streaming is greater than the phone's ability to charge. Once the battery is depleted the phone can't operate directly off of the charger and shuts off. And that's only if it didn't already shut off due to overheating first.

This is a phenomenal product, I've been using an old iPhone 6s and the quality is very good.

The license subscription is more than I'd prefer to pay, but considering every passable webcam has been sold out since April, it's much cheaper than some disposable USB webcam with horrible quality.
