I have a GV-FE5303 which I installed on my property several years ago. I wanted to take it down to paint and found that I had misplaced the supplied Torx wrench. I have almost every size of Torx (tamper resistant and otherwise) bit but nothing seems to fit the screws. Even worse, none of the instruction manuals or other materials seem to indicate the proper Torx size other than "use supplied wrench". If I had know it was this critical and obscure, I would have made sure to keep the little supplied one safer -- I probably threw it out. Does anyone know what size (tamper resistant?) Torx head is used on Geovision mounts like the GV-FE5303?
