which CCTV

[someonelse]

I'm looking to install 2 - 3 internal wireless cameras but struggle to understand how they work.
* Would like alerts when they detect movement
* facility to switch them on/off easily - I don't want alerts and recording every time I walk past them just want when house is unoccupied
* facility to record. Not SD card (which can be removed by intruder, and is fiddly to review footage)
* record to hub/dvd plugged into TV? Cloud?
* if cloud, how does the signal get there? (and how does it send alerts? Wifi?

I need a better understanding, and recomendations. Thanks!
