    I noticed your primary/secondary DNS is 90.193.78.25

    Try changing it to

    Primary: 192.168.0.1
    Secondary: 8.8.8.8

    Test with that config and let me know how you get on. If you hate google (for privacy or other reasons), use 4.2.2.1 as secondary.

    Just wondering, why 90.193.78.25 for DNS?


    Also once you have got the DNS bit sorted, I would suggest changing the IP from 192.168.0.5 to something much higher.

    Your router uses a protocol called DHCP to give out IP addresses from a pool. Often routers are configured so the first address 192.168.0.1 is reserved for router, and the DHCP pool will hand out addresses from 192.168.0.2-192.168.0.254.

    I would suggest making the pool smaller (e.g. 199 addresses from 192.168.0.2-192.168.0.200) as I suspect 199 is more than enough devices. Then 192.168.0.201-192.168.0.254 will never be given to any devices. Then setup your camera with an address in the 192.168.0.201-192.168.0.254 range so there is no chance of another device being given the same IP address as your camera via DHCP. If you have two devices on same network with same IP address, you will have fun and games.

    In theory the problem I mentioned of IP address clash should never happen, I think router is supposed to send out ARP packets to confirm whether an IP address is in use, but I have seen this issue a few times myself in real life.
