There’s also the fact that Lead Acid don’t catch on fire when they go bad like the Lithium based cells do.

You want to get an IP camera and a switch/router/firewall that supports 802.1x - Port Authentication, along with a VLAN for segregation and MAC filtering because more is better.

With 802.1x the camera has to authenticate / re authenticate using EAP for the port to remain active. If someone rips off the camera and figures out its MAC address to spoof it’s still not going to pass the EAP challenge.

You could go all in and get an Ampere like this one Jeff is testing
