Video signature is not allowed, only the signatures of both parties (or electronic signatures) are valid.

You can sign electronic contracts, pay attention to consensus and use reliable electronic signatures.

According to the provisions of the Electronic Signature Law on reliable electronic signatures, the electronic signature of "locking the real identity of the contracting party, effectively preventing document tampering and accurately recording the signing time" is an electronic signature with legal effect. It is impossible for individuals and ordinary enterprises to make reliable electronic signatures, and qualified third-party electronic signature platforms will ensure the legal effect of electronic signatures through various technologies.

I hope I can help you and adopt it.
