Battery Drains Quickly
- Check Power-Consuming Features: Features like night vision and audio monitoring can consume more power. Try turning off unnecessary features or reduce the screen brightness.
- Use Energy Saving Options: For longer battery life, consider using the VOX (voice-activated) mode, which turns off the screen when no sound is detected.
Display & Audio Issues
No Image on Screen

Poor or No Audio
- Volume Settings: Check the volume settings on both the parent unit and the camera. Make sure they are properly adjusted.
- Interference: Electronic devices operating on similar frequencies can interfere with the audio signal. Ensure there is no interference in the area.
Connectivity Problems
Loss of Signal
- Obstructions and Interference: Ensure there are no physical obstructions between the parent unit and the camera. Avoid placing the devices near electronic devices that may cause interference.
