I just want to tell you that You can enable and disable recording on Reolink cameras using Reolink's API, which supports HTTP requests to control the cameras. You can use a combination of HTML and PHP to send HTTP requests to the camera's API to control recording.
And here's an example of how you can enable recording on a Reolink camera using PHP:

<?php

$url = "http://[camera_ip]/cgi-bin/api.cgi?cmd=snap&action=stop";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

echo $response;

?>
<?php

$url = "http://[camera_ip]/cgi-bin/api.cgi?cmd=snap&action=start";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

echo $response;

?>

Note that you need to replace [camera_ip] with the IP address of your Reolink camera. Additionally, you may need to consult the Reolink API documentation for more information on the available commands and their parameters.

did you manage to solve your problem because I have the same problem

Don't know why its happening

The biggest downside to a mesh WiFi router system is that you need to keep routers plugged into outlets in multiple rooms of your home. If you live in an apartment, or older house with fewer outlets, this may be hard to justify. It can also be a little off putting to have WiFi routers strewn throughout your house.

I'll be sure to keep an eye on this thread. 

 I'm having the same problem as the others.

Use the same computer where you saved the firmware file to access the NVR. Using any web browser, type the IP address of the NVR into the web browser address bar. Log in to the NVR with your user credentials. Navigate to Setup > Maintenance > Maintenance > Local Upgrade > Select NVR.

Did you ever find a solution for this?

Hardware incompatibility. Incompatibility is likely the most common cause of Wi-Fi issues. There are so many hardware vendors with lots and lots of devices. It's tough to keep all of them interoperating well in all scenarios.
