Why do some security photos need to wear security clothes and hats?

The reason why some security photos will wear security clothes and hats is that wearing security clothes and hats in security photos reflects the working status, image and ability of security personnel, and also has certain practical application effects. For security guards, security clothing and hats are their standard work equipment. Wearing a security suit and a security hat in the photo can clearly show your identity and job responsibilities. So some photos of security certificates are wearing security clothes and security caps.
