Thank you, some good options there. I will check out Eufy and Reolink.
I do like the Blink ones, but I’d noticed that you have to buy some sort of hub to use them without a sub, which seems like a bit of a pain.
The ring doorbell might work, I guess it’s just a camera but I dont know if they have local SD storage.
The use case is quite simply some home security while on holiday. The reason I want a battery one is that it can be placed discreetly on a shelf or similar. I do have both extension leads and power sockets, but that’s quite obvious to any potential intruder to have a load of wires trailing everywhere so am after something as discreet as possible.
