Quick Answers to Common Questions

Can I add audio to a Hikvision camera that doesn’t support it?

Answer: Yes, but only if the camera has spare input ports or supports third-party accessories. For example, some models allow external 3.5mm microphones or speakers via auxiliary jacks. However, many budget cameras lack any audio capability—so hardware limits apply.

Do I need special software to hear audio?

Answer: Not necessarily. Basic audio playback works in iVMS-4200 and Hik-Connect. For advanced features like noise reduction or recording scheduling, you might need Hikvision’s SmartPSS or newer versions of iVMS-4200.

Is two-way talk secure?

Answer: Yes—Hikvision encrypts audio streams using AES-128 encryption when accessed via HTTPS or RTSP. Always use strong passwords and enable HTTPS in your camera settings to prevent eavesdropping.

Will audio affect video storage?

Answer: Slightly. Audio adds ~10–20% to file size compared to video-only recordings. On a 2MP camera, expect 1–2 GB more per day of storage. Plan accordingly when setting up cloud or local storage.

Can multiple users talk at once?

Answer: No. Only one party can speak during a two-way talk session. Others can listen but cannot interrupt. This prevents chaos in multi-user environments like offices or schools.

How to Check Audio Support

Visit the official Hikvision product page for your specific camera model (e.g., DS-2CD2386G2-LU). Look for keywords like:

  • “Built-in microphone”
  • “Audio input/output”
  • “Two-way talk”
  • “Audio alarm”

If your camera has an RJ45 port labeled “AUDIO IN/OUT” or a 3.5mm jack, it likely supports audio. Older models may only have video-over-coax without audio.

Example Models That Support Audio

  • DS-2CD2386G2-LU (supports audio input and output)
  • DS-2CD2143G0-I (includes built-in mic and speaker)
  • DS-2CD2T46FWD-I (dual-stream audio)

If your camera doesn’t list audio support, consider upgrading to a model with audio features—or add an external microphone/speaker later.

Step 2: Gather the Right Equipment

Even if your camera supports audio, you’ll need the proper accessories to make it work. Most Hikvision audio-compatible cameras use either RJ45 audio connectors or 3.5mm analog jacks.

Essential Items You’ll Need

  • Microphone: Built-in mic is fine for basic listening, but an external mic improves voice clarity.
  • Speaker: Required if you want to play audio or speak back.
  • Audio cable: 3.5mm TRRS or TS for analog cameras; RJ45 for PoE+ audio models.
  • PoE+ switch: Standard PoE may not deliver enough power for audio + video. Use 802.3at (PoE+) or higher.
  • NVR/DVR: Ensure your recording device supports audio channels.

Recommended Accessories

  • Hikvision DS-1602ZJ (audio extension bracket)
  • Generic 3.5mm male-to-male audio cable
  • External USB microphone (for desktop monitoring)

Tip: If you’re using a wireless camera, check if it includes audio transmission—some do, but many focus only on video.

Step 3: Connect Audio Hardware

Now it’s time to physically connect your audio devices. The method depends on whether your camera uses analog or IP architecture.

For Analog Cameras (with Audio Input/Output Ports)

  1. Locate the “AUDIO IN” and “AUDIO OUT” ports on your camera (usually near the video BNC connector).
  2. Plug one end of your 3.5mm cable into the microphone (for AUDIO IN) or speaker (for AUDIO OUT).
  3. Run the other end to your audio source (e.g., intercom panel, recorder, or amplifier).
  4. Ensure polarity matches: Tip = left channel, Ring = right channel (if stereo).

For IP Cameras Using RJ45 Audio

  1. Use a shielded Cat5e or Cat6 cable with audio lines integrated.
  2. Connect the RJ45 end to your PoE+ switch.
  3. The camera should auto-detect audio input when powered via PoE+.
  4. No extra cabling needed—just ensure your switch supports audio-aware PoE.

Power Considerations

Audio increases power draw by about 1–2 watts. If your camera stops working after enabling audio, upgrade to a PoE+ injector or switch. Avoid using standard 802.3af switches unless your camera explicitly supports low-power mode.

Step 4: Configure Audio Settings in iVMS-4200

Once hardware is connected, you’ll configure audio through Hikvision’s iVMS-4200 client software—the most reliable way to manage advanced settings.
