How to Use Listen-In Audio on Lorex Wired Cameras for Two-Way Communication

Quick Answer

To use listen-in audio on Lorex wired cameras, enable the microphone in the camera's audio settings within the Lorex app or NVR interface, then use the talk button to communicate. Ensure your camera model supports audio and that the firmware is up to date for reliable two-way communication.

Listen-in audio turns a standard security camera into a communication tool. Instead of just watching your property, you can hear what is happening and speak through the camera to warn a delivery driver, greet a visitor, or check in on a family member. Lorex wired cameras with built-in microphones make this possible, and setting it up is straightforward once you know where to look.

This guide walks you through enabling listen-in audio on Lorex wired cameras, using the two-way talk feature in the Lorex app, and fixing common audio problems. We'll also highlight which Lorex models support this feature and what to expect from the audio quality.

Before You Start: Check Your Camera's Audio Capabilities

Not every Lorex wired camera includes a microphone. For example, the Lorex A14 4K IP Wired Bullet Security Camera features listen-in audio with a built-in microphone, while the Lorex 4K IP Wired Turret Security Camera also supports listen-in audio. If your camera lacks a built-in mic, two-way communication isn't possible without adding an external audio device.

Also, confirm that your NVR or recorder supports audio. Most modern Lorex NVRs, such as the Lorex Fusion NVR with 4 IP Bullet Cameras, handle audio from IP cameras. If your system is older, check the NVR's specifications or contact Lorex support to verify audio passthrough.

• Check the camera's product page or manual for 'listen-in audio' or 'built-in microphone'.
• Ensure your NVR firmware is updated to the latest version to avoid audio compatibility issues.

Enable Audio in the Lorex App or NVR Interface

Once you confirm your camera has a microphone, enable audio capture. Open the Lorex app on your smartphone or the NVR's on-screen display. Navigate to the camera's settings, look for 'Audio' or 'Microphone' options, and toggle the microphone on. Some systems also have a separate 'Audio Recording' setting that must be enabled.

If you're using a PoE system, ensure the network cable carries audio data. Wired IP cameras transmit audio over the same Ethernet cable, so no extra wiring is needed. After enabling, test the audio by tapping the microphone icon in the live view to hear what the camera picks up.

• Enable 'Audio Recording' if you want to save audio with your video footage.
• Check the camera's audio level settings to avoid clipping or low volume.

Use Two-Way Talk for Live Communication

With audio enabled, you can use two-way talk. In the Lorex app, open the live view of the camera, then press and hold the microphone or talk button to speak. Release the button to listen. This push-to-talk method prevents echo and feedback, which can happen if the camera plays your voice through a speaker while the mic is still active.

Speak clearly and at a moderate distance from your phone's microphone. The camera's built-in speaker (if present) projects your voice. If your camera lacks a speaker, two-way talk won't work—only listen-in audio. Check your camera's specs to know which features are available.

• Use push-to-talk to avoid echo and feedback loops.
• Position your phone's mic close to your mouth for clearer audio.

Troubleshooting Common Audio Issues

If you can't hear audio or the other party can't hear you, start with the basics: check that the camera's microphone is enabled, the volume on your phone is up, and the app is updated. Restart the camera and the NVR to clear temporary glitches.

Network bandwidth can also affect audio. Wired connections are generally stable, but if your internet is slow, audio may lag or cut out. Check your router's QoS settings to prioritize camera traffic. If audio is choppy, lower the camera's video resolution to free up bandwidth.

• Update the Lorex app and camera firmware regularly.
• Test audio from a different device to isolate the problem.

Step-by-Step: Enable Listen-In Audio on Your Lorex Wired Camera

1. Verify microphone support: Check your camera's specifications for a built-in microphone or listen-in audio feature. If not listed, two-way audio isn't possible without additional hardware. Common mistake: assuming all cameras have microphones. Check before you start.
2. Update firmware and app: Ensure your camera, NVR, and Lorex app are running the latest software. Outdated versions can cause audio features to be missing or unstable. Checkpoint: After updating, restart the camera and NVR.
3. Enable audio in settings: Navigate to the camera's audio settings in the Lorex app or NVR interface. Toggle the microphone on and, if available, enable audio recording. Common mistake: forgetting to enable audio recording if you want to save audio with video.
4. Test audio levels: Use the live view to check audio levels. Adjust the microphone gain if the audio is too quiet or distorted. Checkpoint: Speak at a normal volume and listen for clarity.
5. Use two-way talk: Press and hold the talk button in the app to speak, release to listen. This prevents echo and feedback. Common mistake: holding the button while listening, which can cause feedback.
6. Troubleshoot if audio fails: If audio doesn't work, check network stability, restart devices, and confirm the camera's audio is enabled. Test with a different device if possible. Checkpoint: If problems persist, contact Lorex support for further assistance.
