I had WiFi cameras until my friend showed me how his cameras were jammed when his neighbour had a broad daylight burglary. A van pulled up and a second later the video was completely jammed. Then five minutes later it comes back to normal, but neighbour doors were smashed in. So I got a wired network now, on a separate LAN and have two cameras on each perimeter, so if someone tries to cut the cable (unfortunately I was unable to run the cables inside the wall, so they run in PVC pipes attached to the wall), I very least should have that recorded. Also all my cameras are 4k. The cameras also record to built in SD card. There are also two servers hidden each is pulling the videos from DVR to back up and then one copy is uploaded to external server.
