everything works but it just doesn't look very tidy.
I should point out I don't really know what I'm doing.
Your Windows PC will likely continue to use the static IP address set
under Windows, as you told it to. If you want it to use a fixed IP
address assigned for its MAC via DHCP, remove the IP address setting in
Windows and let it use the address assigned via DHCP. Consumer-grade
routers do not enforce IP address assignment so DHCP leases are just a
suggestion (but like TCAS suggestions should be followed to avoid
The IP cctv camera might be getting its address from DHCP. You could try
looking in your router DHCP lease table and eliminating known devices to
deduce the IP and MAC address of the IP cctv camera. If you have no
instructions or interface, I assume you have connected it over ethernet.
