If I knew who the offender was with a CCTV footage we could curb the behaviour.
Two things come to mind:
1. In the interim, why not buy large CCTV signs and put them up in conspicuous places, such as in the foyer, outside the entrance and near the garage. Even without cameras, the signs will deter bad behaviour; and
2. Even with cameras, capturing an image of an undesirable damaging property does not necessarily mean he will be identified, caught, arrested, charged and sentenced. I think the police have other priorities. But when you do install CCTV, broadcasting their installation with signage should reduce criminal and other anti-social activity.
