I'm going to buy a security camera that operates at 12 Volts 250 milliamps, do I need to perfectly match the transformer?  The same company that sells the camera only sells 500Ma, 1amp, and 1.5 amp transformers.  Are modern devices designed to manage power intake even if more power is necessary?

I wouldn't buy a product from a company that doesn't have matching parts for what they sell.

There are ways around that sort of thing but if your going to invest money in that sort of thing, go with something you can get parts for or upgrade with

The transformer is rated for the MAXIMUM sustained current it can supply. Match the voltage and make sure the current rating is AT LEAST as much or more than the device it is powering needs.

So the 500ma (milliamp) transformer would be perfectly fine.

Thanks man, that's what I suspected would be the answer but I wanted to check.
