I use these, can be set up and used via a tablet, have a storage card in them to record to (bought extra) but as WiFi only need a power lead running to them. One thing I did find is the power cable is a bit short so added their extension one, and put the connector even though “weatherproof” in a little sealed box off eBay.. Cloud is optional which I do not use.
