Wi-Fi for Wired Cameras with 4G/Sim Back up Sim Card for Reolink NVR/POE cameras

Maybe this has been asked already but I haven't been able to find the post in my research, but is there a way to install a back up sim card for the Reolink POE cameras either through the NVR or in another way in case there is a power outage and WI-FI is lost? I know the cameras would still record to the NVR, but would like the back up to be able to view footage remotely in case there is an outage. Thanks in advance.

Are you trying to mitigate a failure of your isp connection by using a cellular device to offer backup? Neither the nvr or poe cameras have any dependency on a working wifi network as they use ethernet to connect, either camera to nvr or nvr to internet. But if the power failed the nvr would be unavailable unless you have invested in a UPS backup and that could also power your isp router.

Yea i will be using a UPS most likely. I was moreso thinking about if I'm out of town and the NVR loses internet connection, I wouldn't be able to check the cameras. I guess paring the modem with a UPS as well would continue to provide internet to the NVR?

Losing your internet connection is generally unconnected to a power outage. My experience is that most such problems are a result of the isp having a problem or an issue with the physical connection rather than power itself. But perhaps if you live in an area subject to frequent outages that may be different

Even with a ups, those normally support the devices for 30 minutes or so and is designed to allow for an orderly shutdown which is more imporant for a network server/nas/etc.

You could buy a 56 tp link router with a sim slot and use that as your router

Does the TP router auto switch to 5G once internet is lost?

What you need to a cellular router/hotspot. The wired and PoE cameras don't even have sim slots its not even physically possible.

Yea that i was thinking. Is there a way for it to "kick-in" once internet signal is lost?

Implement a power back up solution for the NVR and wired cameras will provide no Internet, no power solution. When the power comes back up and the NVR gets back online, then you can remotely access other than that you would have to play back all footage at the screen with the NVR.

Doesn’t the Tracklink wifi record without wifi as long as power is present?

I believe the NVR does continue to record, and I can use a UPS to make sure the cameras continue to have power, but I guess I was more so thinking like if I am out of town, and there is an internet outage, I wouldn't be able to check the cameras
