Hey, if you're talking about becoming a camera as in having a skull of a camera, you can use this command in 1.13-1.15 to give you a skull of a camera.
/give @p minecraft:player_head{display:{Name:"{\"text\":\"Camera\"}"},SkullOwner:"SecurityCamera"} 1
However, if you're talking about becoming invisible and hidden from other players, you can get either use "Essentials" or "Super Vanish", both are available in the plugin list.
Hope it works!
