This isn't going to happen. Wifi battery cameras can only use Reolink software.

No. The battery powered Wifi cameras can only be used with Reolink software. Full stop.

Sounds like your router doesn't handle QoS appropriately.

I have to disagree with the OP. Most people throw out the box, putting it on the box would allow anyone to scan it. Where it is currently located is the optimal location.[br][/br]
The QR code is not the only way to add a camera to the app. The QR code is simply a visual representation of the UID string. When the camera was attached to your app you could have written down the UID code at any time by accessing the camera's information in the app. Also, the UID string is written directly below the QR code on the camera so you could have also written it down before mounting it. There were several opportunities for you to write down the UID code before the camera was deleted from the app.[br][/br]
You have my sympathy that you are going to have to make such a long trip to re-add your camera to the app, but it could have easily been avoided. Reolink should not change how they currently implement the QR code or UID since any changes would make it easier for someone to compromise a given camera by obtaining its UID.

Battery cameras cannot continuously record. Full stop.

It would help if you would tell us which models you have

I thought you would want to know, from other pages on the website, under products, I can easily see the Argus 2E listed. However, from the main landing page for the website, the listing for the Argus 2E is missing. I figured that isn't how it was intended to be.

Which cable are you talking about?

I know on some models the motion detection can have zones masked, not sure if that is a universal feature of the battery cams or not.[br][/br]
I know there is a Reolink app on the app store for Amazon Fire tablets, we were just discussing it in another thread here yesterday. I don't know if the Firestick can access the same app store or not (I'm not a user of the Fire line of products).

Yes, they do sell a black solar panel. However, there is currently a transition going on. They have basically stopped selling the current black solar panel (except for existing stock if you can get it somewhere) which is of an older design, but haven't yet started selling the new black solar panel, which is based on the exact same design as the white one. I believe they will start selling the new black solar panel soon since it has appeared in pictures on the website, but as to exactly when, we'd need someone from Reolink to chime in.
