Can I modify Blink video doorbell to take power supply from 12/5/3V transformer instead of batteries?

I have the Blink video doorbell that I purchased about 1 year ago. First, when I saw the title of the amazon product, they had this in it "... wired or wire-free". So I got fooled into thinking I can connect the video door bell to a dc 12v transformer so I can record 24/7. But then, of course after buying it, I found out how they advertised it was misleading and the 'wired' was only to be used with a chime (which I don't use).

Now, after some time, it was outside and not working because I got tired of replacing the batteries. So I thought of connecting it to a variable power supply with 3V, since it has 2 AA 1.5 batteries connected in series. I connected it to the variable power supply to test the idea of providing the device with power from a transformer. However, the device was only blinking red once and then it stops blinking (normally, it would blink till it get synched). So I increased the voltage to 6V, and I soon regret it. Now, it doesn't blink at all and it stopped working even when batteries are inserted.

I think the fuses got busted. I just need to solder in new fuses and things might work.

However, my question is, is it possible to modify this device so I can connect it to a 12/5V transformer and then I can achieve 24/7 hours recording with motion detection of course without worrying about batteries dying out?

What was the output amperage of your transformer?

Once you find the needed amperage & voltage of the Blink you can put in a in-line resistor.

I'm not really sure if I remember, perhaps 0.2 amps. What is an in-line resistor? Is that just a normal resistor?

Don't have a Blink DB, but I've used this AA battery replacement PS in other 3V devices with no issue: -

Are you sure the PSU you were using output DC? Can’t see any other reason why it wouldn’t work unless the batteries are in parallel?

I used to have a Ring Pro doorbell but replaced it with a Pro 2 and the sneaky Rings gits had replaced the transformer requirements, the Pro needed a 24v AC supply whereas the Pro 2 requires a 24v DC supply so had me scratching my head for quite a while.
