Frequently Asked Questions

Common questions about the H20 Series - answered

What is the difference between the Zenmuse H20 and Zenmuse H20T?

The Zenmuse H20 is a triple-sensor model with a wide-angle camera, a zoom camera, and a laser rangefinder. 

The Zenmuse H20T is a quad-sensor model with a wide-angle camera, a zoom camera, a laser rangefinder, and a radiometric thermal camera.


Both cameras are compatible with the DJI M300 RTK drone.
Are the cameras waterproof?

Under controlled laboratory conditions, the Zenmuse H20 Series meets the IP44 protection level.

This means that the H20 and H20T can be used in wet weather, to a certain extent. But IP44 is not a complete waterproofing.

For a full guide on IP Ratings and flying in wet weather, click here.

The protection level is not permanently effective, and will weaken with wear and tear.

Tips include:

• Make sure the gimbal connector interface and gimbal surface are dry and free of moisture before installing the gimbal.

• Before use, make sure that the gimbal is firmly installed onto the aircraft, and the SD card cover is clean, free of foreign objects, and securely closed.

• Before opening the SD card cover, wipe the surface of the body clean.

What are the image resolutions of the cameras?

 

Radiometric thermal camera: R-JPEG, 640×512 px

Wide-angle camera: JPEG, 4056×3040 px

Zoom camera: JPEG, 5184×3888 px
What video resolutions do the cameras have?

 

Radiometric thermal camera: 640×512@30fps

Wide-angle camera: 1920×1080@30fps

Zoom camera: 3840×2160@30fps / 1920×1080@30fps
Which video format is supported?

MP4 encoded with H.264 compression

What level of zoom can be achieved with the H20 Series?

Both the H20 and H20T can achieve 23× hybrid optical zoom, and a 200× maximum zoom.

What is the minimum focusing distance of the visible cameras of the Zenmuse H20 Series payloads?

 

The higher the zoom factor, the longer the focusing distance.

1×-2.8×, the minimum focusing distance is 1 m.
2.9×-3.9×, the minimum focusing distance is 2 m.
4×-4.6×, the minimum focusing distance is 3 m.
4.7×-14.2×, the minimum focusing distance is 5 m.
14.3×-200×, the minimum focusing distance is 8 m.

If the object is within the minimum focusing distance, the camera will not be able to focus. For example, if the aircraft/payload is 5 m away from a pylon, the camera will not be able to focus at a zoom level greater than 14.2×.
What factors affect the accuracy of the laser rangefinder?

 

Laser rangefinders measure distance using the time of flight of light. Their accuracy could be affected in environments where this ToF is affected: The range will be reduced in smoke, rain, snow, dust, and other environments, and data readings may be jumbled.

When measuring an object with glass or transparent components:

• If the glass is within moderate distance, the distance to the glass will be measured (not the object behind the glass);
• The glass may reflect the laser beam to other locations, resulting in the distance to other locations;
• If the surface of the glass is very smooth or too close, the light will pass through the glass to detect the objects behind, but the range will be significantly reduced.
What is the accuracy of temperature measurements of the Zenmuse H20T?

 

The accuracy is ±2 °C or ±2%, whichever is greater. (Measured at 25 °C in a windless laboratory, 5 m away from the black body).

Note: Black bodies have different emissivity levels, the measurement above is is based on the particular black body measured and for reference only.
What factors affect the accuracy of temperature measurement of the Zenmuse H20T?

 

The reflectivity of objects: Shiny metals have higher reflectivity, resulting in lower accuracy and lower temperature readings.

The temperature of background radiation: A clear, sunny day will have less of an effect on accuracy than a cloudy day.

Air temperature and humidity: The higher the temperature and humidity, the more likely the readings will be affected, and the lower the accuracy.

Distance between the camera and the object: The farther away the object is from the camera, the lower the accuracy.
What is the difference between high and low gain modes in the thermal camera of the Zenmuse H20T?

 

High gain mode: Displays a smaller temperature measurement range at a high quality, the temperature measurement range is -40 °C to 150 °C.

Low gain mode: Displays a larger temperature range at relatively lower quality, the temperature measurement range is -40 °C to 550 °C.
Does the thermal camera in the Zenmuse H20T support digital zoom?

Yes. It supports 2×, 4×, and 8× digital zoom.

What is Flat-Field Calibration or FFC in the Zenmuse H20T?

Flat-Field Calibration is used to optimise thermal image quality so temperature changes can be observed more easily. You can choose to manually enable FFC by turning off the automatic FFC adjustment in settings.

How can I measure temperature using the Zenmuse H20T?

Operators can measure temperature in two ways: Spot Meter for measuring a single position, and Area Measurement for getting different readings in an area.

What is the focal length of the thermal camera on the Zenmuse H20T?

The Zenmuse H20T only has one model. Its thermal camera has a focal length of 13.5 mm (F1.0), equivalent focal length: 58mm, DFOV 40.6°

What happens when the lens fogs up?

The Zenmuse H20 Series is designed to prevent water damage to the camera components. But if the humidity is too high or if the payload is exposed to rain, water vapour could still enter the camera. Once powered on, the electrical components will heat up, causing the water vapour to evaporate, resulting in condensation or fog on the lens. This can usually be solved by turning on the aircraft/payload and waiting for the water vapour to dissipate. When not in use, store the payload in a designated case or a cool, dry place with a relative humidity of less than 40%.

What can I do when the protective glass to the camera fogs up?

A protective material that protects against moisture is added between the lens and the protective glass to prevent moisture condensation on the protective glass. But it could be saturated with moisture if the humidity of the storage location is too high or if a wet payload is put back into the box. This could cause the protective glass to fog up, and it might take a while for the fog to dissipate once turned on. You can use a blow dryer to speed up the process. Again, we recommend wiping the payload dry after water exposure, and storing it in a designated case or a cool, dry place with a relative humidity of less than 40%.

What is Night Scene Mode?

In Night Scene Mode, the camera will switch the IR filter and adjust the ISP parameters to optimise for lowlight environments.

What is High-Res Grid Photo Mode?

In DJI Pilot, by dragging to select an area in wide camera view, an image will be taken using the wide-angle camera while the gimbal rotates to automatically capture a series of photos at 20 MP of the selected area using the zoom camera at the current zoom level. All of the images captured will be stored in the same sub-folder on the SD card, generating an HTML file that can be opened in a web browser to view the overview image and the detailed close-up images.

What is the maximum Micro SD capacity supported?

128 GB. It is recommended to use a UHS-I Speed Grade 3 Micro SD card.

Which apps are compatible?

Currently, the Zenmuse H20 Series only supports the Android version of DJI Pilot.

Can a photograph be taken while recording a video?

Yes. Updating to the latest firmware version is required.

Are timed photos supported?

 

Yes. Updating to the latest firmware version is required.
Which drone platforms are the H20 and H20T compatible with?

The cameras are compatible with the DJI Matrice 300 RTK. Update the aircraft and remote controller with the latest firmware.

Which gimbal port can the cameras be mounted?

They can both be mounted onto any one of the three gimbal ports on the M300 RTK.

How do I upgrade the firmware of the Zenmuse H20 Series?

 

Before upgrading, please ensure that the aircraft is powered off, the Zenmuse H20 series gimbal and camera is securely mounted to the aircraft, the microSD card has enough storage space, and that the intelligent flight battery has enough power.

• Do not power off the aircraft or detach the gimbal and camera from the aircraft during the upgrade, or it may damage the gimbal.
What are some safety precautions that I should keep in mind when using the Zenmuse H20 Series?

 

• Do not aim the camera lens at high-energy power sources, such as the sun, lava, or laser beams. The temperatures of observation targets should not exceed 800 °C, or the camera could be irreversibly damaged.

• Do not place the camera under direct sunlight, in places with poor ventilation, or near heaters.

• Do not power on or off the camera too frequently. Please wait at least 30 seconds before restarting the camera, or it may affect the service life of camera chips.

• Do not hot-swap the microSD card during use.

• Do not touch the camera lens or scratch it with hard objects, as this could result in blurry images.

• Use a soft, dry cloth to clean the surface of the camera lens. Do not use alkaline detergents.

• Store the payload in a designated case that is kept dry and ventilated.
For what scenarios can I use the Zenmuse H20 Series?

Thanks to its wide array of camera capabilities, the Zenmuse H20 Series delivers useful insights in a variety of scenarios.


These include public safety applications such as firefighting, fire prevention, search and rescue, and law enforcement; energy industry application including asset and equipment inspection, geothermal energy exploration, and oil and gas inspection.
Can the Zenmuse H20 Series be used for aerial surveying?

The Zenmuse H20 Series was not designed specifically to meet the accuracy requirements for aerial surveying, but you can use the wide-angle camera to capture images in Mapping missions in the DJI Pilot App.
