No, it is not that way. This a big factory with several thousand employees. Security and non-disclosure are definitely important for the success of the business.
The security wards are doing an important job. They do spot checks to control the employees who are entering or leaving the area. They have to be supported.
The wards can't judge on-the-fly whether a scratched camera is still working or not. That's why I want to remove the camera completely. The wards can quickly judge that a non existing camera doesn't make any pictures.
