Great if you have a doorbell able to cope with 24 volt A/C
Great if your existing doorbell can operate at 24 Volts a/c, than it is possibly a matter of replacing your existing transformer with that provided by arlo, if your existing is less than 24 V a/c (or it's a d/c one, or cannot operate the arlo doorbell)
Advantages over a wire-free doorbell
- no removing and recharging doorbell battery
- possible use of existing wired chimes / ringer.
disadvantages,
- cost of electrician unless you are one.
- difficult (impossible?) getting a 24 volt a/c ringer / bell. Plenty of d/c ones.
There is an issue with its 24 v transformer as it fails to give enough power to the door bell.
The light shows orange colour which means there is not enough power for the video bell to work as expected.
