A security camera can beep to indicate a low battery or a network issue. Other than that, a surveillance system might put out beeps to indicate tampering or issues with the hard drive.
These beeping noises can indicate unnecessary alerts as well. Therefore, you should customize the beeper only for emergencies and specific high-priority events.
- Security cameras usually put out a beeping noise to indicate low power and network failure.
- Video recorders can also put out a beeping noise. Typically, these indicate issues with the hard drive and network.
- You can check the event log of your NVR to pinpoint the exact cause of the beeping noise.
- Restarting devices and checking for loose connections will resolve most of the beeping issues.
- Setting up a UPS for your security camera system will help prevent the hard drive from wearing out sooner.
- You can disable the beeper for events such as motion detection, tripwire, or face detection.
Common Reasons Why Your Security Camera or System is Beeping
Here are some of the main reasons why your security camera might start beeping:
- Low battery
- Issues with the power supply and cables
- Network failure (on the cables, router, or network switch)
- Hard disk errors
- An IVS event has been triggered (tampering, motion, tripwire detection, etc.)
In the following sections, I’ll talk more about each of these options and how to resolve them.

1. Low Battery
Most wire-free cameras will put out a beeping noise when the batteries are low.
Typically, it happens at around 20% battery level. After that, the beeping will become more frequent as the battery drains further.
So, try to recharge the battery. Then, plug it back in and see if the beeping noise dies down.
I recommend checking the user guide for instructions if the beeping doesn’t stop.
That said, you might have to get help from a professional if the battery needs to be replaced.
2. Power Issues Within the Security Camera or CCTV System
In terms of power issues, the reasons why your system might start beeping are due to:
- Faulty power supply
- Loose connections in the power or PoE ports
- Loose or damaged PoE or power cables
- Faults or power surges in the cables or power system
So if you suspect that the beeping noise might be due to a power issue, try the following steps:
- Check the UPS and make sure it’s got mains power coming in. The UPS also gives out a beeping noise when it’s running on the battery with no incoming power.
- Check the VMS or companion app for any alerts or notifications. Usually, the software will indicate what’s wrong.
- Check for any loose connections in your power supplies or power cables. Ensure the PoE indicators are green instead of red.
- Try using a different power supply or outlet. However, make sure the DC ports and the power output match up.
- Also, try bypassing the UPS (connecting directly to an outlet) and see if the beeping goes away.
- Shut down your video recorders and cameras. Then wait a few seconds and power everything back in.
- If all the above fails, get help from a professional. There might be a short circuit or faulty connection.
3. Network Failure
DVRs and NVRs tend to put out a beeping noise if the network or an individual IP camera is disconnected. You can check the event log to confirm if this is due to a network failure or some other issue.
In most systems, the event log will indicate a network error event as “Net Disconnect.”
Troubleshoot Network Failure
Most network issues usually resolve themselves in a couple of seconds and the beeping would go away. However, the beeping will continue if any network cables are disconnected or the router is malfunctioning.
So to troubleshoot this:
- Check if the router or PoE switch is powered on. Look for any indicator lights on these devices.
- If possible, check the entire length of the network cable runs. Make sure the network cables aren’t bent, twisted, cut, or corroded.
- You can also try replacing the PoE or Cat6 cables in the sections which might show signs of damage.
- Alternatively, you can try restarting your network devices or replugging the network cables. Make sure the connections are tight.
- If your cameras transmit wirelessly or via PoE, switch to a wired medium or power it separately through the DC power adapter.
- Restart the Wi-Fi router or network switches. You can do this by unplugging them for a few seconds and plugging them back in.
- If you have cloud storage or FTP servers, check the server status and verify if everything is in the green.
- For cellular cameras, make sure your internet plan hasn’t expired, and also try reinserting the SIM card.

4. Hard Disk Errors
Hard disk errors can be very common in security systems. You can usually identify a hard disk error as the event log will indicate an “HDD Error” on your NVR.
Also, if your NVR is rebooting on a constant loop, it can also indicate an issue with your hard drive.
So when troubleshooting this:
- First, try restarting your video recorder.
- If that doesn’t solve the issue, you can try to reinstall the hard drive.
- To do so, power down and unplug the DVR/NVR first.
- Then, use a screwdriver to remove the top cover of your video recorder.
- Look for the two ribbon cables connected to the hard drive. Make sure these connections are tight.
- You can also try reconnecting them or installing a new hard drive.
- After making any changes, fasten everything back on and restart the video recorder.
Hard disks can be very sensitive to power outages. They can get damaged after suffering from sudden and frequent power outages.
So one of the best things you can do is to connect a UPS to your video recorder. This helps extend the lifespan of your devices and minimize video loss.
5. An IVS or Security Feature Has Been Triggered
Your security camera can also put out beeps whenever a security feature has been tripped. These include:
- Tamper detection
- Motion detection
- Tripwire or intrusion detection
- Face and vehicle recognition
- Other IVS features.
You can disable the beeper for these settings via the VMS or companion app of the software.
Additionally, you can customize the type of alert, recording options, and the beep volume (if you still want to keep it).
So make sure to check for this option and disable or adjust the beeper as necessary.
Security cameras can beep due to several issues. This includes low battery power, system errors, connection problems, or even issues with the storage medium.
To troubleshoot, start with the CCTV settings. Then, ensure a stable power source, and verify proper installation. However, if you can’t solve the issue, it’s important to get help from professionals.
Remember, the beeping noise isn’t just a disturbance; it’s your security system indicating emergencies and other information.
