  • Better evidence: Video without audio is like a movie with no soundtrack. Audio adds context and clarity.
  • Remote monitoring: Listen in from anywhere using your smartphone or computer.

Hikvision cameras support audio input (microphone) and output (speaker). Some models have built-in mics and speakers. Others let you connect external devices. Let’s dive into how to make it all work together.

Types of Audio Connections for Hikvision Cameras

Before you start wiring, know that Hikvision cameras support different audio formats. Choose the right one based on your model and needs.

Analog Audio (3.5mm Jack)

Most Hikvision cameras have a 3.5mm audio jack for input and/or output. This is the most common way to add audio. It supports:

  • Microphones: For recording sound.
  • Speakers: For playing sound or two-way talk.
  • Audio splitters: To combine mic and speaker into one line.

Example: The DS-2CD2T47G1-L has both mic and speaker ports. You can plug in a mic to record and a speaker to play audio back.

Digital Audio (SIP/ONVIF)

Some advanced models support digital audio over IP networks using SIP (Session Initiation Protocol) or ONVIF standards. This lets you:

  • Use VoIP phones or apps for two-way talk.
  • Stream high-quality audio without analog wires.
  • Integrate with intercom systems.

This requires a compatible NVR or VMS (Video Management Software).

Power over Ethernet (PoE) with Audio

Some PoE switches and cameras support audio over Ethernet. You can send power, video, and audio through a single cable. This is ideal for clean, minimal installations.

What You’ll Need

Gather these tools and parts before starting:

  • A Hikvision IP camera with audio support (check specs for mic/speaker jacks).
  • A microphone (if not built-in)—USB or 3.5mm.
  • A speaker or headset—for listening or two-way talk.
  • Cable: 3.5mm audio cable or RJ45 Ethernet cable (if using PoE audio).
  • PoE switch (optional but recommended for PoE setup).
  • Hikvision NVR or VMS software like iVMS-4200.
  • Computer or mobile device for configuration.

Step-by-Step: Connecting Analog Audio to Hikvision Camera

If your camera has a 3.5mm audio jack, this is the easiest method. Most Hikvision models do. Follow these steps:

Step 1: Identify the Audio Ports

Look at your camera. You should see small labels near the video connector. Common labels:

  • AUDIO IN: For microphones.
  • AUDIO OUT: For speakers.
  • Some models have both. Others only one.

Example: On the DS-2CD2T86G0-I, you’ll find AUDIO IN and AUDIO OUT near the RJ45 port.

Step 2: Connect the Microphone

If you want to record sound:

  1. Take a 3.5mm male-to-male audio cable.
  2. Plug one end into the camera’s AUDIO IN port.
  3. Plug the other end into your microphone (or use a USB mic with adapter).

Tip: Use a condenser mic for better quality, but a basic electret mic works too.

Step 3: Connect the Speaker or Headset

For listening or two-way talk:

  1. Plug one end of the audio cable into the camera’s AUDIO OUT port.
  2. Plug the other end into your speaker or headset.
  3. Make sure the volume is low at first to avoid feedback.

Note: If you have both mic and speaker, you may need an audio splitter. Or use a headset with mic built-in.

Step 4: Power the Camera

Connect the camera to a power source or PoE switch. Most Hikvision cameras use DC 12V or PoE.

Step 5: Open the Camera Settings

Use a web browser to access your camera:

  1. Type the camera’s IP address into the browser.
  2. Log in with your username and password.
  3. Go to Configuration > Audio Settings.

Step 6: Enable Audio Recording

In audio settings:

  • Turn on Audio Input.
  • Set Audio Compression to G.711 (best quality).
  • Enable Audio Detection if you want motion alerts with sound.

Step 7: Test the Audio

Speak into the mic and listen through the speaker. Adjust levels in the settings if needed. You can also check the live view—you should see an audio meter moving when sound is detected.

Setting Up Two-Way Audio with Hikvision

Want to talk through the camera? That’s two-way audio. It lets you listen and speak at the same time. Here’s how:

Use a Headset with Mic

The simplest way:

  1. Plug a 3.5mm headset into the camera’s AUDIO OUT port.
  2. Use the mic part to speak, the earpiece to listen.
  3. Enable Two-Way Audio in the camera settings.

Use External Speakers and Mic

For louder sound or group monitoring:

  1. Use an audio splitter to connect mic and speaker to the camera.
  2. Or use a powered speaker and mic combo.
  3. In iVMS-4200, go to Channel Settings > Audio and enable two-way audio.

Configure iVMS-4200 for Two-Way Audio

  1. Open iVMS-4200 and add your camera.
  2. Right-click the camera > Playback.
  3. Click the Talk button (megaphone icon).
  4. Select your mic and speaker from the dropdown.
  5. Start talking!

Pro Tip: Keep the environment quiet to reduce background noise. Use a directional mic for clarity.

Using PoE for Audio and Power

PoE (Power over Ethernet) sends power and data over one cable. Some modern switches support audio too. This reduces clutter and simplifies setup.

Check Compatibility

Not all PoE switches support audio. Look for:

  • PoE+ (802.3at): Can handle audio better than standard PoE.
  • PoE++ (802.3bt): Best for high-power devices including audio.
  • Hikvision PoE Switches: Like DS-3E0105P-E, support audio over Ethernet.

Wiring Diagram

With a PoE switch:

  1. Run one Ethernet cable from the switch to the camera.
  2. The switch powers the camera and carries audio data.
  3. No separate power supply needed.

Configure Audio in the Network

  1. Access the switch’s web interface.
  2. Find Port Configuration > Audio.
  3. Enable audio on the camera’s port.
  4. Test the connection through iVMS-4200.
