1. No Video Signal or Black Screen

When your CCTV camera shows a black screen or “no signal” message, it generally means there’s a connection or power issue.

How to Fix:

• Check Power Supply: Make sure the camera and DVR/NVR are turned on.
• Inspect Cables: Loose or damaged cables often cause transmission loss. Reconnect or replace them if necessary.
• Switch Ports: Try connecting the camera to a different channel or port to isolate the problem.

2. Blurry or Out-of-Focus Video

Clear footage is important for identification and evidence. Blurry images can appear for several reasons.

How to Fix:

• Clean the Lens: Use a soft cloth to wipe off dust or fingerprints.
• Adjust the Focus Ring: Gently rotate the lens ring until the picture becomes clear.
• Check Lighting Conditions: Poor lighting or glare from nearby sources can affect clarity.

3. Night Vision Not Working

If your CCTV system doesn’t show clear pictures in the dark, it could be a night vision problem.

How to Fix:

• Inspect IR LEDs: Make sure the infrared lights around the camera lens are glowing slightly red in the dark.
• Remove Obstructions: Check for dirt or spider web blocking the sensor.
• Adjust Camera Position: Ensure the camera isn’t facing reflective objects like glass.

4. Camera Not Recording Footage

Sometimes, your CCTV system might show live video but fail to record.

How to Fix:

• Check Storage: Verify that the hard drive has enough room.
• Enable Recording Settings: In the DVR/NVR menu, ensure the recording schedule is properly set.
• Format or Replace Hard Drive: If the drive is faulty, try replacing it.

5. Flickering or Distorted Image

Flickering lines or distorted video can be irritating and affect tracking.

How to Fix:

• Stabilize Power Supply: Use a stable power adapter or UPS to avoid voltage fluctuations.
• Replace Low-Quality Cords: Poor-quality cords can cause signal interference.
• Check for Ground Loops: If multiple devices share different power sources, it may cause confusion.

6. Remote Viewing Not Working

If you can’t view your CCTV footage remotely on your phone or computer, network settings may be the reason.

How to Fix:

• Check Internet Connection: Ensure that both your DVR/NVR and mobile device are linked to the internet.
• Update App and Software: Use the latest mobile app and software versions.
• Reconfigure Network Settings: Recheck the IP address, port forwarding, and cloud account login information.

7. DVR or NVR Not Booting Up

A non-responsive recorder can prevent you from watching or recording footage.

How to Fix:

• Check Power Adapter: Replace the adapter or power cord if damaged.
• Disconnect External Devices: Remove any USB drives or useless devices.
• Restart the System: Perform a soft reset and see if it boots properly.
