I've tried to post this on superuser.com but they don't accept questions from Tor network now for more than a week so I hope I can find help here since we could say it's network administration question. :)
I wanna set up home CCTV system- few IP cameras, switch, router and laptop.
Note: I know my share about networking and computers, I got previously cameras working on another router but it has internet access so I want to separate it.
Objective:
I got cameras (Hikvision) on their positions. Each is connected to switch and from switch (Hikvision) one connection to old router (TP-Link) and router to laptop (everything's cat5 cable, no WiFi). Also, setup does not have internet connection.
Problem:
I'm not sure if this is missing information about networking on my part or router problem. Thing is, when I plug old router (one to take care of cameras only) into laptop I can't find gateway (it's just blank area after writing ipconfig command (Windows laptop)) and laptop's IP address is weird number- 169.254.105.121(Although according their web internal IP format should be 192.168.1.1 or 192.168.0.1. Also subnet is 255.255.0.0 instead of 255.255.255.0. Another thing, I was not able to find router's web server - I've tried IP's from their web and IP's according to laptop's IP and few others without result. I did reset router few times, no luck.
I've found while writing about not needing gateway when there is no internet but isn't it needed for router to route traffic between devices even on LAN? Does that mean I just change cameras IP to match laptop's IP (this router's format)? Still, what about router's web server? I think I'm gonna need it to set cameras IPs as static instead of dynamic.
Question:
How could I accomplish objective considering where I am stuck at?
