Facing issues with your security cameras? Check these common problems:

• No Display (Video Loss): Check the BNC connectors, power supply, and cables. Often, a faulty power adapter is the culprit.
• Fuzzy or Blurry Images: Clean the camera lens. If it is a varifocal camera, check the focus ring.
• Night Vision Not Working: The IR LEDs might have failed, or the power supply is not providing enough amps for the IR to turn on.

For complex issues, it is best to hire a professional CCTV repair service.
