I’m a beginner of electronic, need to learn a lot. I know I can hire some one to do it, but this is very interesting project I would like to learn.


My door bell power supply is 18 volt DC. and my camera is power up with 12 volt DC. how can I use them together ?


Thanks all for helps

Tony

Your door bell is probably feeded from a spechial transformer, that is AC voltage - so there will be two separate systems.

What is the brand name of your Camera doorbell?
First thank for your supported
My door bell name is Skydoorbell. And the old one is AIPHONE JF -2ME

Tell us the amperage or wattage ratings of the bell and camera.

You may be able to use your18vdc power supply to feed the doorbell and tap off of it with a Lm7812 regulator to feed your camera.
Current ratings are rather important, unless you don't care if the camera drops out when someone rings the doorbell. :D
