dahua nvr and camera ip change

[perthish80]

hello everyone
im having a dahua 5 camera setup with 1 nvr
my setup is simple in wich all the wiring is comming from the camera to a network switch and from the switch a single wire to my router for all 5 camera
wheras the nvr is directly connected to the router via ethernet port
recently i have changed the carrier of my ISP and so i had the reconfiure the network on a whole in which i changed the main router web ui to 192.168.1.1 (PROVIDED BY THE ISP)
and my home netwrk to 192.168.2.1 for all my home traffic
so far i am having an issue in which when ever the automaintain feature rebbot my system one of hte camera ip changes and along with it nvr ip also change
i have set ip pool for camera excluding the camera ip set from the router
and set all the camera and nvr on static mannually assigned ip via the router and changed the ip in the cameras as well
however on every restart one of the camera and nvr chnage the ip address which is resulting in locking of that camera feed
any help is greatly appreciated
thankyou in advance

Do not connect the camera's switch to a LAN port on the router, instead run the NVR's LAN port to the camera's switch then camera switch to router (router LAN ports are not that efficient and can choke).

Insure that the static IP's you assigned to the NVR's LAN and all the cams are unique, on the same subnet AND are outside of the router's DHCP pool. Instead, the router may allow for IP reservations but in case it does not OR it's not functioning be on the safe side and use IP's that are outside of its DHCP pool.
You may have to log into the router and change that pool.

Example: Router's LAN is 192.168.1.1, set DHCP pool to .2 to .99, use .100 to .254 for all your static devices.

Maybe your router's "IP reservation" feature is not working, so try what I said:

1) Insure the NVR and cams are configured for a "static" IP.
2) Choose unique static IP's for the NVR and cams that are outside of the router's DHCP pool.
3) Lastly, it may be your browser: log into a cam or NVR using your browser, make a simple change, save it and see if it "sticks".

BTW, what browser are you using?
