@Ryan The no-name amazon PTZ cams that claim 30X optical zoom are nice, re: onvif, wired poe, outdoors, RTSP streams, and long distance IR throw.
The cameras at my WA site have all survived outdoors weather with exception to that one tree branch. My only complaint is the camera claims to be 802.3at standards compliant, but only ever negotiates 802.3af. I have to manyally set the port to 30W of static draw in my switch, otherwise using IR and PTZ cause a reboot if I dont do that.
I also got a 56V injector to pass ""more wattage"" through, but ended up replacing the switch with a c3850-48p-s so i could set the poe wattage manually.
All of my security cameras are on a vlan that only allows DNS resolution of 0.pool.ntp.org and udp123 to those cached addresses. They don't complain one bit.
