Introduction: 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!
Step 1: 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.
Step 2: Disassembly and Locating the Power Input.
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.
Step 3: Soldering.
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.
Step 4: First Test.
Power LED and IR Leds for the night vision seem to be working, succes !
Step 5: Optional: Adding a Power Switch.
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.
Step 6: Reassembly and Final Test!
We are done! And with succes!
Now you can mount your doorbell camera anywhere you would like!
