Battery Power Conversion for Video Doorbell.

In a local ad I found a free video doorbell with monitor.
The nerd in me did not hesitate for a moment and I picked it up.

Not having an ac outlet nearby the door I decided to try and make my video doorbell battery powered.

This turned out to be even simpler than imagined.

Here I will explain in a few simple steps how I achieved this.

Please excuse my English, it is not my native language.

Thanks for reading!

What Power Does It Need ?

First of all I looked at the AC adapter output and it shows 9V DC.

This is great as this means I could use a little 9V brick battery.

Disassembly is easy as there was only 1 screw.

Next I looked where i could solder the battery in place on the board.

And there is just enough room for it!

Like it somehow was meant to be.

This requires a little soldering.
I soldered a 9V battery clip from my parts bin onto the board where the AC adapter plugs in.

Find the ground and power with a multimeter if you can, if it doesn't work you should know to flip the wires around and try again.

Power LED and IR Leds for the night vision seem to be working, succes !

To save the little battery when not needed I soldered a switch between the power line.

Drilled a hole in the back side of the case and hot glued everything in place.

The battery is held on to the back with double-side sticky tabs.

We are done! And with succes!

Now you can mount your doorbell camera anywhere you would like!
