Step 1: Log Into Your Hikvision NVR
Start by accessing your NVR. You have two options: local (direct) or remote (network).
- Local access: Connect a monitor and keyboard to your NVR via HDMI. Power it on and log in using your admin credentials.
- Remote access: Open a web browser and type the NVR’s IP address (e.g.,
192.168.1.100) into the address bar. Use the Hik-Connect app or iVMS-4200 for mobile or desktop access.
Once logged in, you’ll see the main dashboard. Look for the Configuration or Setup menu—this is where the magic happens.
Warning: If you’ve never logged in before, the default username is usually admin and the password is the one you set during setup. If you forgot it, you may need to reset the NVR (see FAQs).
Step 2: Navigate to Camera Audio Settings
Click on Configuration > Camera > Video & Audio. This is where you control audio for each connected camera.
You’ll see a list of all your cameras. Click on the one you want to enable audio for (e.g., “Camera 1”). Then, look for the Audio tab or section.
- Check the box that says Enable Audio.
- Set the Audio Input Type to Mic In (for cameras with built-in mics) or Line In (for external mics or audio devices).
- Adjust the Audio Sampling Rate (usually 8KHz or 16KHz—16KHz gives better quality).
For 2026 models, you might also see options like Audio Compression (G.711 or AAC). AAC is better for low bandwidth, but G.711 works well on local networks.
Pro Tip: If the “Enable Audio” option is grayed out, your camera may not support audio. Double-check the model number or try another camera.
Step 3: Configure Audio Encoding and Bitrate
Still in the Video & Audio settings, scroll down to the Encoding section. This controls how the audio is compressed and stored.
- Set Audio Encoding to MPEG Audio or AAC.
- Set Audio Bitrate to 32 Kbps (good balance of quality and storage).
- Ensure Audio Stream is enabled (usually “Stream 1” or “Main Stream”).
Why does this matter? Higher bitrate = better sound but more storage used. If you’re recording 24/7, 32 Kbps keeps files manageable without sounding like a robot.
For 2026 NVRs, you may see a new option: AI Audio Enhancement. Enable it if you want clearer voices in noisy environments (like parking lots or warehouses).
Step 4: Check Audio Input Source (For External Mics)
If you’re using an external microphone (not built into the camera), you need to make sure the NVR knows where to get the audio.
- Go to Configuration > Camera > Video & Audio > Audio.
- Under Audio Input Source, select Line In.
- Connect your mic to the camera’s audio-in port (usually a 3.5mm jack or terminal block).
Example: You have a DS-2CD2443G0-IW with an external mic connected to its audio-in port. Without setting Line In, the NVR won’t “hear” anything.
Warning: Some older cameras require a powered mic (phantom power). Check your camera’s manual. If the mic isn’t working, try a powered one.
Step 5: Enable Audio on the Main Stream (Critical!)
This is a common mistake. Even if you enable audio, if it’s not on the Main Stream, you won’t hear it during playback or live view.
- Go to Configuration > Camera > Video & Audio > Video.
- Select Main Stream (not Sub Stream).
- Look for Audio and make sure it’s set to Enable.
Why? The Sub Stream is often used for mobile viewing and may not include audio. The Main Stream is what gets recorded and played back in full quality.
For 2026 models, you might see a Dual-Stream with Audio option. Enable it if you want audio on both streams (great for remote viewing on phones).
Step 6: Test Audio Live and in Playback
Now, let’s make sure it works. Go back to the live view screen (press Live on the NVR interface).
- Click the Audio icon (looks like a speaker) in the camera preview.
- You should hear sound from the camera’s mic.
- Speak near the camera to test clarity.
Next, test playback:
- Go to Playback mode.
- Select a recent recording (within the last few minutes).
- Click the Audio icon during playback.
- You should hear your voice or background noise.
If you hear crackling or no sound, check your audio input source and bitrate settings (Step 3).
Pro Tip: If audio works live but not in playback, the recording may have been made before audio was enabled. Always test after making changes.
Step 7: Enable Audio in Hik-Connect App (For Remote Viewing)
Want to hear audio when you check your cameras on your phone? You need to enable it in the Hik-Connect app.
- Open the Hik-Connect app.
- Tap your NVR device.
- Tap the camera you want to hear.
- Tap the Audio icon (speaker) in the live view.
- Allow microphone permissions if prompted.
For 2026 NVRs, the app may auto-detect audio-capable cameras. If not, make sure your phone’s data/Wi-Fi connection is strong—weak signals can mute audio.
Note: Some carriers or Wi-Fi networks block audio streams. If it doesn’t work, try a different network or use iVMS-4200 on a PC.
Step 8: Save and Reboot (If Needed)
After making changes, always Save your settings (click the floppy disk icon or “Apply”).
For some 2026 models, a reboot is recommended:
- Go to System > Shutdown > Reboot.
- Wait 2–3 minutes for the NVR to restart.
- Log back in and test audio again.
Rebooting clears temporary glitches and ensures all settings are applied correctly.
Pro Tips & Common Mistakes to Avoid
Even with the right steps, things can go sideways. Here are the most common pitfalls—and how to avoid them in your How to Enable Audio on Hikvision NVR in 2026 Easy Guide journey.
Pro Tip 1: Use the Right Cable for Audio
For external mics, use a shielded 3.5mm audio cable. Cheap cables can pick up interference, causing buzzing or humming. If you hear a loud hum, swap the cable.
For terminal block connections, ensure the mic’s ground wire is properly connected. Loose wires = no sound.
Pro Tip 2: Check Camera Firmware
Sometimes, the camera itself needs an update. Go to Camera > Camera Info > Upgrade and update each audio-capable camera. Newer firmware often fixes audio bugs.
Common Mistake: Forgetting the Main Stream
You enabled audio… but it’s only on the Sub Stream. As mentioned in Step 5, always check the Main Stream settings. This is the #1 reason people think audio isn’t working.
Common Mistake: Wrong Audio Input Type
Using Line In on a camera with a built-in mic? You won’t hear anything. Match the input type to your hardware. When in doubt, start with Mic In for internal mics.
Pro Tip 3: Use Audio Alarms (2026 Models)
Newer NVRs support Audio Alarms. Go to Configuration > Event > Audio Detection and set sensitivity. If someone shouts or glass breaks, the NVR can send you a push notification with audio clips. Great for warehouses or stores.
Common Mistake: Ignoring Network Bandwidth
Audio uses extra bandwidth. If your network is slow, audio may cut out. Use AAC encoding and 32 Kbps to reduce load. For Wi-Fi cameras, ensure signal strength is above 70%.
Pro Tip 4: Label Your Cameras
Once audio is working, rename your cameras (e.g., “Front Door – Audio On”) in the NVR settings. This saves time when troubleshooting later.
FAQs About How to Enable Audio on Hikvision NVR in 2026 Easy Guide
Let’s tackle the questions we get most often. These answers will save you hours of frustration.
Q1: Why is the “Enable Audio” option grayed out?
This usually means your camera doesn’t support audio. Check the model number. If it’s a non-audio camera (like DS-2CD2043G0-I), you’ll need to replace it with one that has a mic (e.g., DS-2CD2347G2-LSU/SL). Or, connect an external mic and set the input to Line In.
Q2: Audio works live but not in playback. What’s wrong?
You recorded the video before enabling audio. The NVR only saves audio if it’s enabled at the time of recording. To test playback, speak near the camera after enabling audio, then check the recording.
Q3: How do I enable audio on multiple cameras at once?
Unfortunately, Hikvision doesn’t have a “bulk enable” feature. You must enable audio for each camera individually. But you can speed it up: after setting one camera, copy settings to others via Configuration > Camera > Copy to.
Q4: Can I add audio to an old NVR that never had it?
Only if the NVR supports audio input (check specs). Most 2018+ models do. Also, your cameras must have audio capability. If both conditions are met, follow this guide. If not, you may need to upgrade hardware.
Q5: The audio is too quiet. How do I fix it?
Go to Configuration > Camera > Video & Audio > Audio and increase the Audio Input Volume (usually 0–100). Set it to 70–80 for best results. Also, clean the camera’s mic (dust can muffle sound).
Q6: Does enabling audio use more storage?
Yes, but not much. Audio adds about 10–15% to file size. For example, a 1TB drive that holds 30 days of video might now hold 25–27 days with audio. Use AAC encoding to minimize the impact.
Q7: How do I disable audio if I don’t need it?
Go to Configuration > Camera > Video & Audio > Audio and uncheck Enable Audio. Also, disable it in the Main Stream settings. This saves storage and reduces bandwidth use.
