CamPark BM20 Two-Way Talk Feature Not Working

If you're trying to use the two-way talk feature on your CamPark BM20 baby monitor but encounter issues—such as not hearing your child through the monitor, your voice not transmitting from the parent unit to the camera, no sound being picked up, distorted or low audio, or screeching feedback when the devices are too close together—follow this troubleshooting guide for possible solutions.

The VOX (Voice Operated Exchange) sensitivity controls how easily the monitor is triggered by sound. If it’s set too low, the system may not detect your baby’s voice or other sounds.

How to Fix It:

1. From the main interface on the monitor, press the Up or Down arrow buttons.
2. Adjust the VOX sensitivity level—start by increasing it.
3. Press OK to confirm the new setting.
4. Test by making a moderate noise near the camera.

The monitor’s speaker volume may be turned down, making it difficult or impossible to hear audio from the camera unit.

How to Fix It:

1. From the home screen of the monitor, press the Volume Up (+) button repeatedly to raise the volume.
2. Ensure the speaker isn’t muted or damaged.
3. Test the volume again by speaking near the camera.

If the monitor and camera are placed too close, the speaker and microphone may create a feedback loop, causing a howling or screeching noise.

How to Fix It:

• Reduce the monitor volume to prevent the microphone from picking up its own output.
• Move the monitor and camera at least 3–6 feet apart.
• Avoid pointing the monitor’s speaker directly at the camera.

The CamPark BM20 uses wireless signals that can be disrupted by high-powered electronics or dense physical barriers.

Common Interference Sources:

• Wi-Fi routers
• Microwaves
• Cordless phones
• Thick walls or mirrors
• Trees or large furniture

How to Fix It:

• Move the monitor and camera away from known sources of wireless interference.
• Test the system in another room with fewer obstacles.
• Try placing the monitor higher up or in a direct line of sight with the camera.

If you've tried everything, either the speaker or microphone may have failed and will need to be replaced.
