Hm, while most cameras had diodes at the power input meaning that DC would work fine, I found one (Burle model - have very few of these that tested good) that seems to have a transformer and won't work on DC. If you wonder what a camera supports let me know, but as long as you're using a switching dc power supply it shouldn't damage the power supply or camera if you connect a DC power source to an AC-only model.
