Hey Tom,
If I just record to SD card on the camera then isn't the system rather weak to having the camera stolen? I was thinking about doing that, just not sure on the pros and cons. Or if there is way to automate downloading the SD card to the cloud via the Ethernet cable (I kind of assume such a thing is possible, just not sure how easy to setup).
Budget wise is a bit tough as I don't know exactly what I need. I guess up to £200, but ideally a lot less
