I'm pretty sure it's an EEO violation to request ID or a photo before hiring.
"Similarly, employers should not ask for a photograph of an applicant. If needed for identification purposes, a photograph may be obtained after an offer of employment is made and accepted."
This does not seem relevant when you're already on a video call. The prohibition on requesting photographs is to prevent otherwise unknown information about their race/gender/etc.
