I am about just rip out everything Reolink and never recommend it to anyone again. I mean the most BASIC elements are either missing, broken, or removed after a botched firmware update. The latest: the Windows client app has ZERO functionality to save the camera layout. Nope. Imagine spending the time placing 16 cameras in an order to make logical sense EVERY TIME THE APP IS STARTED or EVERY TIME YOU SWITCH LAYOUTS. What an absolute garbage experience. And when I submitted a support request / feature request for this, they start with the same process having NOTHING TO DO with what I am saying. HOW BASIC is a save layout function????????????????????????????????????

This ended up being..... ANOTHER REOLINK BUG (but two factor):
Factor 1 - The NVR had no timer tab in scheduling.
Factor 2 - The NVR firmware polling Reolink reported it was already on the latest firmware (so no update was reported or loaded if using the NVR GUI or Windows Client on the NVR and trying the 'Check for Latest Version').

After searching manually for a new firmware I found the recent Aug 3, 2025 update which, after manually updating, reveals.......... THE TIMER TAB.

But guess what bug still exists! That's right the "no audio on high speed playback if viewing only one channel" bug. One must go to the 4 channel view (even if only viewing one channel) to have audio on high speed playback. Reolink needs to be renamed to BUGLink. Crazy how buggy Reolink is.

Before being able to access your cameras again through their web interface, you will need to access the camera settings through a reolink client app or NVR and re-enable the HTTP protocol. Nobody knows why Reolink does such strange things like COMPLETELY change device configuration on a firmware update. Just one of so many unexplainable / unprofessional Reolink attributes.

I have now used my one post every 24 hours to answer your question (another ridiculous reolink thing). So I can't help the other two people I have answers for.

@workoholicspam_335979423842535 , please let me know what came of this. I know this is an old topic but I just had the same thing happen to me from "NEW" firmware. Why TF would they remove Exposure, Shutter, Backlight, and 3D DNR with the newer firmware? Now my RLC-511 Cameras and RLC-410 cameras with this firmware "update" are useless. I have attached a before and after. Sadly, the only reason I started to update firmware on these cameras was because my RLN36 NVR did not have a timer tab for recording schedule. That turned out to be a BUG IN THE NVR FIRMWARE. geeeez Reolink, seriously.

Here is what Advanced Display Settings were before the new firmware:


The advanced display settings after the firmware update (SMH):

This community is dead. Probably better response rate on Reddit. Anyway, I solved the issue myself by finding the next previous version of the firmware and rolling back the firmware on the cameras.

Sadly, I have tried helping several people who have recently posted but as a new user I am limited to one post per 24 hours until a magic fairy grants me points. <---- This, if you ever wonder why the Reolink Community forum is so inactive.

I recently discovered a new downstream switch (Netgear GS308P) was not getting along with any of the 3 reolink cameras. This caused a lot of what you're describing from a UE stand point. One thing to check to investigate if there may be a switch incompatibility is full time recording. If you playback where you expect full time recording and you notice a very consistent pattern of small dead spots (black / blank / no recorded footage), then you may have a switch that just doesn't play well. I did so much testing on this and actually can't really say it was an incompatibility with the cameras (as it could have also not been playing well with the NVR). Just try to sub out the switch and see what happens. Might save you some time and guess work.

I have the RLN-36 and connected to it several RLC-520, RLC-511, RLC-410, and RLC-522. I have no way to stop full time recording on these. On the NVR UI, The Windows Client UI, and even through the web interface direct to the camera, the scheduling section lacks a timer tab. Sure, I can schedule alarm hours, but that does nothing. I can have everything selected or everything not selected (and yes saved), and the system still records full time and still designates motion events on the playback. I have always run Digifort (for over 10 years), but I switched the this Reolink NVR and I really want it to just work properly.
