Recently bought a few new Hikvision 4mp cameras and found they changed from the solid Metal Mounting base to a plastic mounting plate that does not fit the wall mount brackets and do not hold as tight as the DS-2CD2332-I cameras did. I tool the New Eyeball from it's plastic socket and found that it fits in the old frame. are there any of these old DS-2CD2332-I Bricked cameras around that I could get the mounting frames from?
