Security for your Security System Network - WIFI vs. Ethernet
I have a general question about how one sets up their security system - curious what people with more experience think...
I've noticed many "outdoor" cameras that are Ethernet only, and it raises the question of physically exposing your network to the outside of your building (exposed ethernet cable outside the building): Ethernet vs. WIFI. I know there are other considerations besides security (speed, wiring, POE, etc) but strictly from a network security perspective, is one better than the other?

Many cameras allow you to mount them directly on the hole where the cable comes through the wall, so in this case the cable isn't visible and can't be easily accessed.
Or, you could set up an entirely separate network just for your cameras. You just need the Mac running SecuritySpy to have two network interfaces: one for the camera network and one for the main network (for Internet access etc.). This also has the advantage of pushing camera traffic off your main network.
In general, Ethernet is always going to be faster and more reliable than WiFi, especially for external cameras, as external walls of buildings tend to significantly attenuate WiFi signals.
I understand that the WIFI is less reliable and slower with it's connection, but I guess I'm wondering if a WIFI password is more secure than an exposed ethernet cable (even if only exposed after removing camera).
You can get cameras which are hardwired into your security system and detect tampering.
many axis cameras have additional input ports ( which SSpy can read ) where you could put a magnetic sensor.
I glue my cameras to my security system via a mess of node.js, which is monitoring camera state via on-camera triggers
