Night Scene

Choose Auto Night Scene mode, or turn Night Scene on or off when the main screen shows the zoom or the wide camera view. The setting of the Night Scene mode applies to both the zoom camera and the wide camera simultaneously. In Night Scene mode, the recording frame rate of both the zoom and wide cameras will be decreased to optimize the image quality in low-light environments.

• Auto: Night Scene mode will be enabled automatically in low-light environments.
• ON: Tap to turn on Night Scene mode. Select from Enhanced Noise Reduction and IR Light when Night Scene mode is set to ON. Enable Enhanced Noise Reduction to achieve a better image quality.

Note that the recording frame rate will decrease further if Enhanced Noise Reduction is enabled. Use this function with caution for situations where low latency in liveview is required. If IR Light is enabled, the zoom camera will disable the IR filter to optimize the image quality in low-light environments. The Zoom camera will display a black-and-white image once IR Light is enabled.

Temperature Measurement (for infrared thermal cameras only)

• Spot Meter
  Tap any position within the temperature measurement area on the screen to measure the temperature.
• Area Measurement
  Drag to select an area within the temperature measurement area on the screen. The lowest temperature, the highest temperature, and their corresponding locations in this area will be displayed on the screen. Tap the icons below the selected area box to:
  1. Close the area measurement page.
  2. Maximize the page.
  3. Take a screenshot of the measurement result.
  4. Enable/disable Temperature Alert;
  5. Set alert temperature. After Temperature Alert is enabled, users can set the alert temperature.
     Once the highest temperature exceeds the set alert temperature, the remote controller will issue a warning sound.

Temperature measurement accuracy is affected by various factors:

1. Reflectivity of objects – Shiny metals with high reflectivity will reflect more of the background radiation and result in lower accuracy, whereas objects with matte surfaces will produce higher accuracy.
2. Temperature of background radiation – Sunlight affects temperature measurement accuracy, so the infrared thermal camera should be kept out of exposure to direct or reflected sunlight.
3. Air temperature and humidity – Temperature and humidity resistance have been calibrated before delivery, but some temperature measurement errors are inevitable. Extreme temperatures or humidity levels will affect measurement accuracy.
4. Distance between the camera and the object – The default distance used in calibration is 5 m, which generates the most accurate temperature measurement. Deviations from this distance will lower the accuracy.
5. Emissivity of objects – The emissivity of the object will affect temperature measurement accuracy. Generally, accuracy increases proportionally to emissivity. Emissivity is affected by factors such as the material, the roughness, or the degree of oxidation of the object’s surface.

Hints and Tips: When measuring a blackbody 5 m away at 25° C in a windless indoor environment, using the High Gain Mode, the wide infrared thermal camera provides an accuracy of up to ±2° C or ±2% (whichever is the larger value), and the tele-infrared thermal camera provides an accuracy of up to ±5° C or ±4% (whichever is the larger value). Since the emissivity of different blackbodies varies, this measurement result only represents the accuracy of the tested blackbody and is for reference only.

Updating Firmware

Ensure the aircraft, the remote controller, and the Zenmuse H20N have all been updated to the latest firmware. Otherwise, usage may be affected. Do not power off the aircraft or detach the gimbal and camera while updating the firmware. Restart them once the firmware update is complete.
