i see.
If my requirements is simply to have camera around the house for monitoring when we are away and to save the footage to cloud storage and to have alerts send to the mobile phone/app when there is motion detection at night or when we are out of house, would a simple solution from Google nest cams or even Tuya IP Cams suffice?
google nest cams/ tuya ip cams probably cost <$100 each and with 10 cams , it will only cost <$1000 and probably monthly cost of $10 a month for the cloud storage
You may also consider Xiaomi security camera. I am using 2 for internal monitoring with 24h recording to SD card. The model I use allows for motion detection alert at a preset time period.
