Is not putting a security camera at home a law or just a landlord decision?

I live in low income housing for the disabled and elderly. I wanted to put a security camera in my living room window inside for security reasons. We have some in the main entrance to the building and that's all. None outside or in the hallways. My car has been vandalized and ransacked several times. I was told by my property manager that I cannot take video of the other tenants. I explained to her that it may be another tenant doing this and I don't feel safe here at night. Public Safety is of absolutely no use, it's after the fact and you have no proof.
