Video Surveillance System Maintenance Tips

When it comes to DVR/NVR video surveillance system maintenance, paying attention to the recorders fans is crucial for their optimal performance. Here are some best practices to keep in mind.

Regular cleaning is the top tip of the regular video surveillance system maintenance.

Dust and debris can accumulate on the fans, hindering their ability to cool the device effectively. Clean the fans regularly using compressed air or a soft brush to remove buildup. Make sure the Camius DVR or NVR is powered off before cleaning.

Check for proper airflow is the 2nd tip of regular security camera maintenance.

Ensure that the DVR or NVR is positioned in a well-ventilated area. Ensure enough space around the device for proper airflow, as inadequate ventilation can cause the fans to work harder and potentially overheat.

Avoid blocking vents

Ensure that the vents on the DVR or NVR are not blocked by objects or other equipment. Blocking the vents can impede airflow and lead to overheating.

Monitor fan performance

Keep an eye on the fan’s performance. If you notice any unusual noises, decreased airflow, or the fans not spinning properly, it could indicate a problem. In such cases, contact the manufacturer or a professional technician to address the issue.

Protect Your DVR or NVR With Stable Power

Stable power helps maintain continuous recording and protects the recorder while it saves settings, performs system operations, or updates firmware.

Follow these power-protection practices:

  • For the best protection, connect the recorder to a UPS battery backup with automatic voltage regulation.
  • A surge protector helps protect against voltage spikes. A UPS adds battery backup during brief outages and provides additional protection from certain voltage fluctuations.
  • Connect the recorder to a battery-backed outlet on the UPS. Some UPS units also include surge-only outlets that do not provide battery backup.
  • Use the original Camius power adapter supplied with the recorder. Contact Camius before replacing it with a different adapter.
  • Make sure the power adapter, AC plug, and recorder power connector are securely connected.
  • Use a continuously powered outlet. Avoid switched outlets, timers, smart plugs, or power strips that turn off with a television or other equipment.
  • Avoid sharing the recorder’s power source with high-load equipment such as heaters, air conditioners, refrigerators, compressors, or large office equipment.
  • Select a UPS with enough capacity for everything connected to it. If continued remote access is important during an outage, consider connecting the router and external PoE switch to the UPS.
  • Check the UPS battery periodically and replace it according to the UPS manufacturer’s instructions.

Shut Down the Recorder Safely

Camius DVR and NVR recorders are designed for continuous operation. When you need to disconnect, move, or service the recorder, use its on-screen Shutdown option before turning off the rear power switch or disconnecting the power adapter.

Wait for the shutdown process to complete before disconnecting power. Avoid turning off the recorder while it is starting, saving settings, formatting a hard drive, resetting, exporting data, or updating firmware.

If the recorder is frozen and the on-screen menu cannot be accessed, power cycling may be required for troubleshooting.

Protect the Recorder During Firmware Updates

Use only firmware provided for your exact Camius model. Before starting an update:

  • Connect the recorder to a stable power source, preferably a UPS.
  • Do not perform the firmware update remotely.
  • Do not disconnect the power, network connection, or USB drive during the update.
  • Allow the recorder enough time to complete the update and restart.
    Back up the recorder settings before updating when this feature is available.

Download firmware and review update instructions on the Camius Firmware page.

Back Up Your DVR or NVR Settings

After completing the initial setup or making important configuration changes, export a copy of the recorder settings to a USB flash drive. A settings backup makes it easier to restore your preferred configuration when settings are reset or transferred to another compatible recorder.

Store the exported file in a safe location. Create a new backup after making important changes to camera, recording, network, alarm, or user settings.

Follow the Camius guide to back up your DVR or NVR settings.
