Hello, I want to put a camera on my front door somewhere, and I notice the only power I can see is the feed for the doorbell. Can I hook up a camera to this and if so how? I'm thinking a wifi camera, the one I have here takes DC5V2A but probably will buy a new one. let me kn0ow if you can help, thanks

I have one on my front door powered by battery, hole drilled though door, lens on the outside, camera and push button on the inside, plug and play job £49 from The Orange shed
 
My advice would be no because the camera (whether it's 5V, 12V or whatever) is going to want a nice clean smoothed supply. I think it's highly unlikely a doorbell transformer will be clean or regulated enough.
 
A few possible problems here.
1) Is the doorbell just a momentary switch? If so then you may not actually have power available.
2) is the voltage the same?
3) is there enough capacity to feed the camera?
4) The regulation/smoothing of the DC voltage, as per Sparkychick's post.
 
Well, the bit of wire where the bell connects ...

I reckon the OP is thinking about the wired bell push ! :rolleyes:
yeah I think its the bell push wire, haha !
 
whatever that is ...

Your camera needs a positive and a negative, like any low voltage DC powered stuff does. All you have there is a postive feeding your switch, and then a switched positive coming back. There is no negative (aka 0V) to complete the circuit. Does that make sense?
