[john walker's workshop]

i just got done cleaning up the third graffiti mess on my roll-up door in a month. i guess that's nothing compared to some areas. last couple of months have seen a dramatic increase in the little bastard's quest to turn a decent neighborhood into a ghetto. i've been thinking about installing cameras for a while, but i need some that are easily concealed, meaning small, that project a clear image, even in low light. i haven't seen much online. everything is too large and too obvious. can someone recommend a setup that won't take me to the poorhouse?
