Mobile phone: If you broadcast live by mobile phone, generally speaking, you need to prepare two mobile phones, one for live broadcast and the other for viewing the barrage messages of the audience in the live broadcast room. Two mobile phones work together. Computer: If you use a computer to broadcast live, you need a high-profile computer and a good-quality computer camera. On-site sound card, microphone, monitor headphones, fill light, mobile phone bracket, mirror, etc. They are all necessities.
