Troubleshooting Hikvision Coaxial CCTV Systems: Why Isn‘t My DVR Recording?107

Hikvision coaxial CCTV systems are widely used for their reliability and cost-effectiveness. However, encountering issues like a DVR failing to record can be frustrating and disruptive. This article delves into the common reasons why your Hikvision coaxial system might not be recording footage and provides comprehensive troubleshooting steps to help you resolve the problem.

The first step in troubleshooting a non-recording Hikvision system is to systematically check the various components involved. Let's break this down into several key areas:

1. Camera Issues

Before even considering the DVR, ensure your cameras are functioning correctly. A seemingly simple oversight, a malfunctioning camera is the most frequent cause of a non-recording system. Here's a checklist:
Camera Power: Verify that each camera receives adequate power. Check the power supply at the camera itself and trace the power cable back to the source. Loose connections or a faulty power supply are common culprits. Look for blown fuses or damaged cabling.
Camera Connection: Inspect the coaxial cable connections at both the camera and the DVR. Loose or corroded connections can interrupt the signal. Ensure the BNC connectors are firmly screwed in and that the cable isn't damaged or kinked.
Camera Settings: Access the camera's settings (if possible, either via a web interface or on-site menu) to ensure it's correctly configured to send video. Check if the camera is set to record, and that the image settings (resolution, frame rate) are appropriate.
Camera Image Test: Use a monitor or the DVR's live view feature to check if the camera is sending a video signal. If you see a picture, the issue likely lies with the DVR's recording settings. If not, focus your attention on the camera itself and its connections.
Multiple Cameras: If only some cameras aren't recording, isolate the problem to those specific cameras and follow the steps above for each affected unit.

2. DVR Issues

Assuming your cameras are working correctly, the problem likely resides within the DVR (Digital Video Recorder). Let's investigate the common DVR-related problems:
Hard Drive Issues: The most common cause of recording failure is a hard drive problem. Check the DVR's hard drive status:

Is the hard drive correctly installed and recognized? Access the DVR's menu to check for hard drive errors or low storage space. A full hard drive will prevent further recording.
Is the hard drive failing? Look for unusual noises or vibrations emanating from the DVR. A failing hard drive might require replacement.
Is the hard drive formatted correctly? The DVR needs to properly format the hard drive to function correctly. If the hard drive has been recently replaced, it will need formatting within the DVR's system settings.


Recording Settings: Ensure that the recording schedule is correctly configured. Check if recording is enabled, and if it's set to record continuously, motion detection, or scheduled times. Incorrect settings will prevent recording, even if cameras and hard drives are working.
Network Issues (for networked DVRs): If your DVR connects to a network, ensure the network connection is stable. A network outage or incorrect IP settings can affect recording capabilities. Check the DVR's network settings and ensure it's correctly connected to your network.
DVR Firmware: Outdated or corrupted firmware can lead to various malfunctions. Check for firmware updates from Hikvision's official website and update the DVR accordingly.
DVR Power Supply: Ensure the DVR's power supply is functioning correctly. A failing power supply can cause intermittent recording issues or complete failure.

3. Coaxial Cable Issues

While often overlooked, the coaxial cables themselves can be the source of recording problems. Check for the following:
Cable Damage: Inspect the cables for any visible damage, such as cuts, kinks, or excessive bending. Damaged cables can interrupt the signal, preventing recording.
Cable Length: Excessively long cables can degrade the signal quality. If possible, shorten the cable length or use a signal booster if necessary.
Cable Connections: Ensure all BNC connectors are securely connected at both the camera and DVR ends. Loose connections are a frequent source of signal loss.

4. Seeking Professional Help

If you've exhausted all of the above troubleshooting steps and your Hikvision coaxial system still isn't recording, it's best to seek professional assistance. A qualified CCTV technician can diagnose more complex problems, such as internal DVR faults or advanced network issues. They possess the specialized tools and expertise to effectively identify and resolve the problem quickly and efficiently. Attempting more advanced troubleshooting without proper knowledge can potentially damage the equipment further.

By systematically checking these areas, you can significantly increase the chances of identifying the root cause of your Hikvision coaxial system's recording problem. Remember to always prioritize safety and, when in doubt, contact a professional.
