If you’re camera shy, here's good news. No, you don’t have to be the one in front of the camera. It’s preferable to have someone in upper management star in the video, but if there’s a team member who has a strong charismatic personality and social skill set that would make them excellent in front of the camera, there’s no rule that says it must be HR or upper management. Remember, this is an attraction recruitment tool. No matter who you select to be the star, the main goal is to highlight the position and company’s appeal. If the security guy has the strongest “it” factor in the company (and you know he will convey the company mission and position’s appeal with the excellence needed for the video), then it would be in the best interest of the video to ask him to be the star.
