Where can I buy Infrared Cameras that do NOT have Infrared LED's on them?

My reasoning is that if i get cameras all with IR LED's, then if someone who is sneaking up on me has an IR camera without any LED's, then he can see every one of my camera locations. So that option is ruled out. I want some with LED's to light it up outside a bit, then have other ones without them at other locations, using the ones with LED's to see. The yard is partially lit anyway. This way the snooper thinks he can get around them, but instead gets an up close mugshot by the hidden cameras without the LED's! :) I'm not necessarily worried about break ins, but people who snoop around the property and steal things for copper and such, like the pipes for the air conditioner, extension cords, etc. People like "partially smart meth head geekers..." They are not brave enough to break in around here, but will snag anything laying around that they can haul off for scrap metal, which i need to keep for parts...
