Is Your Reolink NVR Beeping? – (Quick & Easy Fix)

Confused and concerned about the Reolink NVR beeping? Don’t worry, this guide will help!
In some cases, the beeping produced by your Reolink NVR can vary from a simple cause such as the motion buzzer, or something more complex such as a stuck system.
The Reolink NVR has several causes for beeping:
This quick guide will help you identify the exact cause of the beeping and provide thorough instructions on how to apply the best working solutions.
How To Fix Reolink NVR Beeping? – (7 Quick & Easy Steps)
Tip: Try rebooting the NVR to check if the beeping stops!
1. Check for Active Motion Buzzer

The first thing to check in case of a beeping Reaolink NVR is whether the motion buzzer has been activated.
Upon motion detection by one of your connected Reolink cameras, the motion buzzer will cause the NVR to beep for several seconds up to a minute based on longevity.
If you’ve made certain that the motion buzzer has activated, then this is a perfectly normal operation of your NVR and you shouldn’t do anything additionally.
You can view the live streams of all connected cameras and check which one has picked up motion, causing the motion buzzer’s activation.
2. Power Cycle the Reolink NVR

As mentioned, the beeping of the Reolink NVR can be set off by several types of buzzers, including a system fault buzzer.
Often, a simple power cycle should resolve temporary system issues with the NVR and restore the live feed access to all of your cameras.
- To power cycle the Reolink NVR, push the “On/Off” switch of the NVR to the “Off” side and unplug the power adapter for approximately 60 seconds.
Once the NVR has fully discharged, reconnect the power cable back into the power and flip the switch back to “On.”
Wait until the NVR’s system loads completely and check for the beeping.
3. Check for a Camera Video Loss
If one of your Reolink cameras is unable to record or store video files, it would almost certainly cause the NVR or camera to beep repeatedly.
The insufficient power supply of security cameras is the most often culprit to repeated loss of video information and other files.

To prevent video loss, check the following things on your system:
- The power supply condition and consistency of all cameras.
- The quality of the PoE switches, Ethernet cables, and ports.
- The selection of the PoE injectors and the installation quality.
- If using battery-powered cameras, the condition of the battery.
- Interference by nearby systems, wireless units, or Bluetooth.
- Free up bandwidth by reducing the number of paired cameras.
You should keep in mind that all NVRs have a limited bandwidth that can be distributed among connected cameras.
So, exceeding the number of allowed cameras, even though there may be a greater number of ports on the NVR, could result in a persistent loss of your video materials.
4. Free Up Space on the NVR’s Storage
A storage or HDD failure can trigger the exceptional buzzer’s activation of your NVR’s system.
Although most HDD-related issues must be reported to Reolink, you could check if the storage has been over-exceeded, which could also result in the beeping.

Follow these steps to access the NVR’s HDD storage:
- Locate the VGA/DVI/HDMI port on your Reolink NVR.
- Connect a compatible monitor over a video cable unit.
- After it loads up, access the configuration of the Reolink.
- Head to “Device Settings” and then “Disk Management.”
- Check the current capacity of the NVR’s integrated HDD.
- If the capacity is over 95%, reduce it to at least 75%-80%.
You can free up space on the NVR by uninstalling old video files that have been captured and stored by the connected cameras.
If releasing storage does not help either, and you are certain that there’s an HDD defect, we would recommend quickly getting in touch with Reolink support.
5. Inspect All Cameras’s PoE & Internet

The PoE (Power over Ethernet) and Internet status of each connected Reolink camera could cause the NVR or Reolink camera to beep.
This is a type of exceptional buzzer, as it could either be caused by power or internet loss by one of the connected Reolink cameras.
5.1 How to Check Reolink Cameras for PoE Issues?
Reolink NVR cameras use a direct Ethernet connection with a port on your NVR that is both used to deliver power supply and internet.
In order to check if there’s a PoE issue, determine if either of the cameras has physically shut down or temporarily disrupted the live feed.
In case one of your cameras has powered off, attempt to use the built-in “Power” button to reboot and check if the live feed will sustain additional disruptions.
5.2 How to Check Reolink Cameras for Internet Issues?

Apart from the camera’s power supply, an inactive internet status could also set off the NVR’s exceptional buzzer beeping.
If that’s the case, ensure each of your cameras is recognized by the NVR through the system monitor and try reconnecting the Ethernet cable.
If no internet is delivered to your camera, replace the Ethernet cable with a brand new one and check if the beeping stops.
6. Deactivate the Reolink Buzzer Feature
If you’re systematically bothered by the buzzer and can’t seem to identify the exact cause, it’s recommended to disable the feature through a web browser of the Reolink client.
The outcome will be identical regardless of the source you pick for the buzzer’s deactivation.

To deactivate the buzzer, you will need monitor access to the NVR:
- On your monitor, access the “Device Settings” tab.
- Click on your NVR from the left navigation menu.
- Next, head to “Surveillance” and press on “Buzzer.”
- Click the “Enable Buzzer” button so it turns gray.
- Exit the menu and check if the NVR is still beeping.
Tip: The beeping can be configured to go off in the event of motion, video loss, and other exceptions.
7. Restore the NVR to Factory Defaults
If manually deactivating the buzzer did not help with the Reolink NVR beeping, then we certainly recommend a clean factory reset.
All you need is a compatible screwdriver to remove the outer casing of the NVR and a flashlight to search for the “RESET” button.

Identify the screws holding the NVR’s outer panel attached, use a screwdriver to lose them, and hold the “RESET” button for 10–15 seconds.
The rectangle shape of the NVR means that the outer casing will be found right on top of the NVR, so the screws could either be on the rear-upper end or one at each corner.
Ensure the NVR is plugged in throughout the entire procedure and reinstall the casing after the reset.
Alert: Do not touch any of the electrical components within the NVR while the unit is plugged in!
