I. If ever we caught someone who unintentionally scratched our car and the person doesn't have capability of paying.

II. Someone is leaning on it, are we going to tell them everytime not to lean on it?

III. If someone intentionally damages our car like breaking the glass, given for example there is already barangay CCTV that is guaranteed working do I still need to buy my own?

Any other benefits of having a CCTV to secure our cars?
Is CCTV really worth it? Why? Thanks for all the inputs.
