I asked some friends who told me 3C would have it but they looked at me strange when I asked and said no, they don’t sell that. When I asked who sells one they shrugged.
Hoping someone here knows.
Basically id like to see who is outside without physically answering and wireless so I don’t need to drill anything.
Yes, most of them can use the original door bell cabling. Just check the voltage and amperes, make sure it is supported by the device.
You might have to let an electrician check that out for you.
These are cheap, wireless although need a power source. Good quality video and 2 way audio, excellent low light capability. Check them out in one of the physical stores.
This one has 360 view, motorised and controlled by cellphone, 米家智慧攝影機 雲台版 - 小米台灣官網
Smaller non motorised, which I think has better night vision;
But be aware it has no IP rating, not weather proof. You should install it under a roof if you go that way.
So just leave your door bell and use that camera as ‘Intercom’.
I have this camera and use it as a kids monitor when we are busy doing other things.
I bought it in a sale for ca. 500twd on singles day.
