Hikvision Night Vision Not Working? Here’s How to Fix It
If your Hikvision camera is failing to provide night vision despite working normally during the day, you're not alone. This issue often stems from IR LED malfunctions, IR cut filter problems, or incorrect settings. The good news is that most issues can be resolved with targeted troubleshooting steps. Below, we’ll guide you through a structured approach to diagnose and fix the problem, focusing on Hikvision-specific tools and features.
Quick Fixes to Restore Night Vision
Before diving into complex diagnostics, try these simple checks that can resolve 80% of night vision issues within minutes:
- Power cycle your camera: Unplug the camera (or remove the battery for battery-powered models) for 30 seconds, then reconnect. This can resolve temporary software glitches.
- Check LED status in the app: Open the Hik-Connect app, go to the camera’s Device Health menu, and look for LED status. If the IR LEDs are not activating, the issue may be hardware-related.
- Verify power supply: For wired models, ensure the transformer at the junction box provides 16-24V AC. For battery-powered models, check the battery level in the app and recharge if below 20%.
- Restart the Hik-Connect app: Force-close the app and reopen it. This can refresh the connection between the app and the camera.
- Confirm app login credentials: Ensure you’re logged into the correct account and that your subscription (if applicable) is active.
Step-by-Step Troubleshooting for Persistent Issues
Check Your Camera’s Night Vision Settings
- Open the Hik-Connect app and navigate to the camera’s Video settings.
- Look for Night vision mode and ensure it is set to Auto or On. If it’s set to Off, enable it and test.
- For Hikvision ColorVu models, check the Lighting settings to ensure the supplemental white light is enabled (if you want full-colour night vision) or disabled (to avoid bright lights).
- If using H.265+ Smart Codec, switch to H.264 in the Video settings to ensure compatibility with your NVR or third-party software.
Inspect for IR Reflection or Obstructions
- Ensure no reflective surfaces (e.g. windows, mirrors) are within 5 meters of the camera. Reflections can confuse the IR sensors.
- Check the lens for dirt, fog, or condensation. Clean the lens with a microfiber cloth if necessary.
- For outdoor models, verify that the camera is not pointing at a dark surface (e.g. a wall or tree) that absorbs IR light. Adjust the angle if needed.
Use Hikvision’s Video Quality Diagnosis Tool
- In the Hik-Connect app, go to Device Health → Video Quality Diagnosis.
- Follow the on-screen prompts to assess night vision performance. The tool will highlight any issues with IR LED functionality or signal strength.
- If the diagnosis indicates a hardware fault (e.g. faulty IR LEDs), contact Hikvision support via their official website for repair or replacement options.
Update Firmware and Network Settings
- In the Hik-Connect app, go to Device Health → Firmware update. Ensure your camera’s firmware is up to date. If an update is available, follow the prompts to install it.
- For Wi-Fi-connected models, check the Network status in the app. Ensure the camera is connected to a 2.4GHz band (5GHz can cause issues with some Hikvision models). If signal strength is low (RSSI below -70dBm), move the camera closer to the router or use a Wi-Fi extender.
- For wired models, ensure the Ethernet cable is securely connected and not damaged. Test with a different cable if possible.
Factory Reset for Persistent Issues
Is your camera battery-powered or wired?
- Battery-powered → Press and hold the reset button on the back of the camera for 10 seconds until the LED flashes. This will restore factory settings. Reconfigure the camera in the Hik-Connect app.
- Wired → For models like the DS-2CD2087G2-LU or DS-2CD2143G2-IU, press and hold the reset button for 10 seconds when the camera is powering on or rebooting. This will erase all settings and require re-pairing.
After a factory reset, ensure the camera is re-paired with your network and that all settings (e.g. night vision mode, H.265+ codec) are correctly configured.
Advanced Diagnostics and Support
Analyse Diagnostic Logs
- In the Hik-Connect app, go to Device Health → Diagnostic logs.
- Look for error codes related to night vision (e.g. IR sensor failure or IR cut filter malfunction). These logs can help pinpoint hardware issues.
- If logs indicate a recurring problem, contact Hikvision support with the logs attached for faster resolution.
Contact Hikvision Support
If troubleshooting steps fail, visit Hikvision’s official support page to submit a support request. Include:
- Camera model (e.g. DS-2CD2347G2-LSU/SL)
- Diagnostic logs from the app
- Photos of the camera’s LED status and any error messages
- Details of the issue (e.g. “Night vision not activating despite correct settings”)
Hikvision’s support team can guide you through advanced diagnostics or arrange a replacement if the camera is under warranty.
Understanding the Root Causes
Night vision failure in Hikvision cameras is often due to one of three factors:
- Hardware faults: Faulty IR LEDs or a damaged IR cut filter can prevent night vision from activating. This is common in older models or after exposure to extreme weather.
- Incorrect settings: Night vision mode may be disabled, or H.265+ Smart Codec may be incompatible with your NVR or app.
- Environmental factors: Obstructions, reflections, or poor signal strength can interfere with night vision performance.
In the UK, construction materials like solid brick or foil-backed insulation can severely impact Wi-Fi performance, which may affect wireless models. For wired models, ensure the transformer voltage is within the required range (16-24V AC).
Prevention and Long-Term Care
To avoid recurring night vision issues, follow these best practices:
- Regularly update firmware via the Hik-Connect app.
- Clean the camera lens and check for obstructions during routine maintenance.
- For wireless models, ensure the camera is within range of a 2.4GHz Wi-Fi network.
- Use Hikvision’s Storage health check tool to monitor the camera’s performance and address issues early.
Full disclosure: we built scOS to address exactly this—the frustration of cameras that depend on Wi-Fi to function. scOS uses permanently powered cameras connected via Ethernet, eliminating signal dropouts and ensuring consistent night vision performance.
When to Replace Your Camera
If troubleshooting has failed and the camera is beyond its expected lifespan (3-5 years for battery-powered models, 5-8 years for wired models), replacement may be necessary. Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods. If your camera is under warranty, contact Hikvision support for a replacement. For older models, consider upgrading to a newer Hikvision model with improved IR sensors and dual-stream support.
