I decided not to go with a wired system for ease of installation and I could never really find what type of system was best to use for integration with SmartThings (or home automation in general). I was hoping to find a system that allowed viewing of each camera via IP address (for use in SmartTiles /etc). Also integrated IP cameras, motion detection output for SmartThings, etc…
I went with Arlo wireless/battery/outdoor cameras by Netgear, they are officially integrated with SmartThings. They aren’t cheap though, you might find some holiday deals get them down to about $100 per camera. Biggest con for them is a delay between motion and start of recording which could cause you to miss important face shot of intruder. There is also a new “Pro” line out that adds local recording (vs cloud). I thought old Arlo’s were getting local recording to USB stick???
There is also Blink, similar to Arlo (wireless/battery), but not outdoor yet (probably ok if kept dry).
I didn’t research the other Samsung, Nest, etc… camera as they seemed to be even more expensive or not outdoor.
