Hey @Stevndar! When wiring up your Video Doorbell to existing wires, you will want to check the following to ensure for proper voltage:
- Transformer rating is 8 - 24VAC
- The wiring is standard gauge wires and not too thin (ex: spliced cat5)
- The wires are connected securely to the Video Doorbell and a diode is installed if connected to a digital chime kit. If chime kit is mechanical, do not use a diode.
The above should lead to a charging of your battery, depending on usage and battery temperature. Check out our Community post about battery draining for more tips on extending battery life. I hope this helps!
