HD-TVI DVR DS-7204HTHI-K1 and IP CAM DS-2CD1323G0-I issue

[Rycki]

Hello.
I have a really intersting question. There is a DS-7204HTHI-K1 dvr and for the 5. channel I use an IP camera DS-2CD1323G0-I.
I use a LTE / 4G Tp-Link TL-MR6400 router, because there is no wired internet.
The problem is, the IP camera come off from the network or just a connection problem. But it is still on the network.
On the monitor the 5. channel said "NO LINK" for the IP camera.
But in the DVR menu where I can add the IP camera, I see it, but I need to remove and re-add again for the normal working.
I use the newest firmware for the DVR and for the IP camera.

About the network config. I don't use DHCP. The DVR and the IP cam is use fix internal address. The DVR is 192.168.1.100 and the IP cam is 192.168.1.101.
In the router I make an address reservation for these IP address and use the MAC address to.

So my question is, WHY?? Every time I readd the IP cam, is working for 4-5 days and after that it goes "NO LINK".

The physical things like UTP cable, UTP plug has no problem I test it.

Sorry for my bad English.

Sorry, nothing springs to mind.
Your settings seem OK.
We never work with the hybrid DVRs, as we are pure-play IP.
My first recommendation is normally to install the latest firmware - you have done so.
Maybe check the logs in Config -> Maintenance to see if there are any clues ...
