4. Night Vision Issues: Replace the infrared LEDs if the camera's night vision capabilities are weak or compromised.

5. Freezing or Lagging Video: Optimize the camera's network settings to ensure a stable connection. Ensure that the recording device has sufficient storage capacity.

Troubleshooting Steps:

1. Power Issues:

Check the power adapter and cable for any signs of damage.
Connect the camera to a different power source or use a different power adapter.

2. Video Signal Issues:

Inspect the video output cable for any cuts or breaks.
Tighten the video cable connections at both ends.
