I've had BI up for a couple of years now with 15 h.264 and h.265 cameras, and I bought an Annke 5MP to replace one of the older h.264 models. I ran their SADP software network camera discovery tool and it said the camera was set to port 192.168.0.167 (attachment #1). I don't think I have anything as high as 167, so I hooked up in place of an older camera at 192.168.0.113, and told BI to use 192.168.0.167 (attachment #2). There's something (lots, evidently) that I don't understand about networking and subnets. My internet connection router has 4 ports on it and one of them goes to an 8-port switch, and the BlueIris computer and a 16 POE port switch are plugged into that, and all 15 cameras work except the new one. Sorry so stupid - can anybody tell me what's wrong? Maybe I can find some freeware to draw me a picture of the network.
