@Ari, Then you might be interested in this Readers Digest study of 'lost wallets', where wallets that had $100 (local currency) and id/phone#, were intentionally abandoned in busy urban areas of the 16 largest countries...
Is a camera with a sign that says “Smile You’re On Candida Camera” less likely to be vandalized than one that says “These Cameras Will Be Used to Prosecute ALL Shoplifters?"
These proposed messages are subtly different than those in the study, since those messages were all self-referencing and oriented towards self-preservation:
A."I would really be appreciative if you didn't take me." B. "Please don't steal this camera" and C. "If you steal this camera you will be arrested".
So I'm not sure its directly applicable in this case because those messages are not even pleading, stating or threatening any consequences to the vandalism of the camera, like in the study.
I woulod like to know if there is any empirical data showing any impact on parking lot signage referring to the lot being under video surveillance as well as the most effective (if there is any) verbiage.
