While our camera can work on a 16vac to 24vac power supply there are only a very small few of Doorbells in that work with 24vac transformer so please keep an eye out that your not over buying your transformers...
While looking at some manuals you will find that most of them will say that your Doorbell will work with a 16vac 10va or 20va Transformer. Then down some more it will give you a range of voltages that your doorbell can work with and it might look like 18-22vac or 16-22vac and it will still say on the doorbell or box or manual what the Transformer it needs 16vac...
So there are some people out there that have used a 24vac transformer for the doorbell camera and it can use that without an issue because the normal voltage for the camera is between 16 and 30vac Please don't try running your camera on a 30vac supply that is max voltage
So I have a doorbell that I took off my cabin when I put in a different one.. Didn't need a new one just wanted a new one.. So I thought I have this one I will work with it and see what happens...
So i took my 24vac 100va Transformer and connected it to a doorbell camera and a normal switch for the backdoor.. Now mind you this is a very cheap Doorbell lol.. Only needs 16vac and 10va to run... Powered it up and connected the power to it.. All started up and tested things out.. Power worked and things worked for the doorbell camera and the Chime. So I thought ok lets get to pressing... After about 20 to 30 doorbell rings the doorbell stopped working YAY I broke it camera was still working lol... No more chime when button of back or front buttons pushed...
So it is hard to see in the Picture but so far I have traced the fault to a Voltage Regulator that takes the normal 16vac that it should have and after it enters the chime it goes though a Bridge Rectifier or in this case 4 diodes that is being used as one... Then goes into the Voltage regulator and if you look you can't really make it out very well because of the Skid Mark that it made when the Regulator pop making it so it can't send the rest of the board 5vdc rather then the 16vac that it started with... So to ask why did it fail? Well the Regulator will work with voltage upto 25volts and my 24vac has a total output of 26.5vac and it was just time before it over heated and failed..
So in the End please read the Doorbell or manual and make sure you get the Transformer that your doorbell is asking for.. iF you need one that you can power from a 24vac transformer then make sure you buy one for your power supply...
