How To Troubleshoot The Hikvision NVR Beeping

If you’ve recently purchased a Hikvision security system, one of the first things you might notice is its beeping. Unfortunately, there doesn’t seem to be a true solution for this issue. You can do some things to help fix the problem, however, and many of those solutions involve troubleshooting with your NVR unit and your computer.

What is a Hikvision NVR Beep?

If you are experiencing a beeping noise from your Hikvision NVR, there is most likely a simple solution to the issue. 

This blog post will provide instructions on how to troubleshoot and resolve the beeping issue. What is the beeping noise?

The beeping noise you hear is most likely a signal that the NVR has discovered a new video. As you would expect, this signal comes from the camera in your network. This new signal could indicate an event that requires action on your network. For example, it might dictate that a motion sensor has detected motion or that a door has been opened.

For example, we have installed several Hikvision NVRs to monitor the security of our school, and the following image illustrates what a system log looks like when this type of event occurs:

There are two common issues at play if you are experiencing beeps while recording (and not just while rebooting). 

First, the NVR is recording (you can tell this because you will see the light on your camera flash and then switch off a second later). The issue with beeps is that when recording occurs, it can mask any error messages that may pop up, creating confusion.

Second, some specific conditions cause beeps to occur. The video segmenter on the NVR has been configured for H.264 compression. If you are using cameras operating at lower resolutions or data rates, this option can lead to loud beeps as it tries to compress large amounts of data. 

However, not all cameras suffer from this issue, and in most cases, we have found no need to change anything on the NVR to fix these problems. If you find that the beeps are a real problem and you have one of the cameras mentioned above, then we recommend moving to a different camera or camera type. While this may seem like a drastic step, it gives you more control over your recordings.

If you have increased your recording storage space on your NVR, you may have noticed some problems with the beep noise from these cameras when the recording is done. If this is the case and there is no other way to get rid of them (such as using an audio filter), consider using our audio filters or adjusting your audio settings on the NVR to remove them. Please see our complete Camera Problems article for more details: H.264 Recording Noise.

Why does my Hikvision NVR Beep?

Hikvision NVR beeping can be one of the most frustrating problems to experience. There are several reasons an NVR may be beeping, and each requires a different solution. This blog post will discuss the most common Hikvision NVR beeping issues and how to investigate and fix them. Some of the most common Hikvision NVR beeping issues include:

Hikvision NVR is beeping when powered on. Suppose an NVR is beeping when it’s turned on. In that case, some common causes are as follows: Bad power supply or bad battery in the NVR (check all cables and make sure they’re secure), Faulty motherboard or computer Power supply not being able to provide enough current to charge the battery (you may need a higher voltage power supply) Poor cable quality A low battery level, so ensure you are always using a charged battery For more info about what reasons for beeping here’s another blog post about beep issues in Hikvision NVR.

 Much newer Hikvision NVRs are manufactured to be power-saving and will go into a deep sleep mode when the power to the NVR is completely turned off. The NVR will still visually show as powered on, but in reality, it’s powered down. In this case, most of these devices will beep upon being powered up (which means they won’t beep during a live event when someone tries to raid your home with an axe, and they won’t send you emails about water tank leaks). For more information, see this blog post about the Deep Sleep feature in Hikvision NVRs.

Hikvision NVR Beeping Due to Software Issues:

 This is tricky, especially if you have the latest firmware installed on your NVR. The problem is that although most Hikvision NVRs come with their own user interface, they also have a web-based admin panel. This can be accessed remotely via https://ip or an Ethernet cable plugged into port 1 of your router (which every modern router supports).

Does this make it easier for hackers? Yes, it does! For example, suppose somebody wanted to gain access to your network over an unsecured wireless network but could not do so directly due to the password requirement. In that case, he could connect via your NVR instead and gain access to everything on your system. There are communities dedicated to distributing.

How to Troubleshoot the Hikvision NVR Beeping

If you are experiencing the Hikvision NVR beeping, there are a few things that you can do to troubleshoot the issue. First, check to see if the NVR is properly connected to your network. If it is not connected, try connecting it to your network and booting it up. If the NVR still beeps, then you likely have a hardware issue with the device. In this case, you need to contact Hikvision support to figure out the issue. If the Hikvision NVR beeps constantly or is constantly beeping, you likely have clogged or broken wiring within your network. You would need to contact Hikvision support in this case. The Hikvision NVR does not have motherboard replacement parts, so you can’t replace the motherboard yourself. If this is the issue and the problem persists, you will need to bring it into a service centre for repair.

 These are the main issues and problems you may encounter with the Hikvision NVR. If these do not work for you, you should contact a repair service centre to help fix whatever issue you have with the device. Otherwise, watch your system’s performance and ensure it is running at peak performance while using the Hikvision NVR.

Diagnosing the Beep:

  • Hard Disk Errors: A faulty or improperly installed hard drive is a common culprit behind NVR beeps. Check the device’s logs for “HDD error” or “disk full” messages.
  • Improper Installation: Did you forget to format the hard drive or connect it securely? Ensure proper setup and compatibility of your hard drive.
  • Lost Connection: Is your NVR struggling to communicate with cameras or the network? Look for “network error” or “camera disconnected” messages in the logs.

Silencing the Siren:

  • Identify the Error: Access the “System” or “Event” menu in your NVR’s interface to find out what triggered the beeps.
  • Exceptional Ways to Stop Beeping: While temporarily disabling the buzzer in the settings is tempting, it’s crucial to address the underlying problem.
  • Firmware Update: Consider updating your NVR’s firmware for bug fixes and improved stability.
