You CAN take photos to use as evidence, I have tested this in the local courts, successfully. I took photos and frecorded footage from video surveillance cameras (as was suggested by both the Chamber Magistratate and my Lawyer) of the following: all the letterboxes; the common lawn area outside the front of my unit; the driveway; the car park; the balcony of another unit where the resident was on the balcony at the time. I also took audio recordings which the Magistrate was more than willing to listen to thus, proving the Police wrong whom advised me that the person I was recording had to provide me with permission to record them although, it might depend on the particular Magistrate whom is hearing the case (should it get that far). I did initially put up signs in my windows that recording devices were being used but the Police told me this was not necessary to use my video surveillanc cameras so I took them down. Often the actual gathering of the evidence is not illegal, it is the ability to use them as evidence that is debatable. Call the Police if you are unsure, they will clarify or go to a free legal advice appointment in your local community to ask specific questions.
