Maintenance Tips

• Clean Lens & Housing Gently
  Use a soft microfiber cloth to wipe the lens and exterior regularly—this preserves sharp 1080p video and reliable autofocus/zoom performance.

• Inspect Video Connections
  Check 3G‑SDI and HDMI BNC/Type‑A cables and connectors frequently to ensure stable signal output during live production.

• Check PTZ Movement & Presets
  Exercise pan (≈340°), tilt (≈120°), and zoom functions routinely to keep motors smooth and avoid stiction. Save and test presets to ensure quick, accurate recalls.

• Update and Back Up Firmware
  Use the USB or serial interface to update firmware when available—this can improve control stability and compatibility with controllers.

• Maintain Proper Ventilation
  Keep air vents unobstructed and avoid enclosing the camera in tight, hot spaces to reduce heat buildup.

• Secure Mounting & Stable Power
  Tighten mounts/brackets for wall/ceiling installation and use a surge protector or UPS to protect against power spikes.

• Organize Control Cabling
  Ensure RS‑232/RS‑422 or IR remote wiring doesn’t tug or stress ports, which helps maintain reliable PTZ control.

• Optimize Image Settings Periodically
  Re‑calibrate exposure, white balance, and focus based on lighting conditions for consistent image quality.
