Starlight Sensors in DJI Zenmuse H20N
DJI Zenmuse H20N – The ‘N’ in the title stands for ‘Night Vision’, and let’s start right from there. To better understand the DJI Zenmuse H20N, let’s familiarise ourselves with the concept of Illuminance, measured in Lux. It is defined as the intensity of light emanating from a given area. Generally, the human eye struggles to recognise objects when light intensity is below 20 Lux.
The DJI H20N has starlight sensors that facilitate enhanced performance in the low-light scenario. These have a wider aperture and faster shutter speed than other cameras, allowing more light to reach the sensor. That being said, the H20N has double-efficient starlight sensors equipped with zoom and wide-angle cameras, making it an even better option for low-light scenarios. This allows operators to detect light sources as low as 0.0001 Lux— far beyond what the human eye can see. So even during a half-moon night of 0.12 lux, it is still possible to observe anything even 500m away.
The H20N has a zoom camera and wide camera of resolution 4MP and 2MP, respectively. Likewise, it can facilitate 20 times optical zoom and 128 digital zoom. With the High-Res Grid Photo feature, you can frame an area of interest in the wide camera view. Then the zoom camera will auto-capture a set of 20MP high-quality images of the framed target area and stitch these images together into a single image that can be viewed in greater detail.
Comprehensive and Synchronised Dual Split-screen view
The Synchronised Dual Split-screen view is something that makes the H20N stand out from the rest of its competitors. As the name suggests, the synchronised split-screen zoom lets the operators to simultaneously sync the zoom between the thermal and starlight night vision cameras. With this feature, users can scale both images simultaneously, enabling us to compare details side by side during critical missions— enhancing visibility.
Thermal Sensors in DJI Zenmuse H20N
Apart from the Starlight sensors, the DJI Zenmuse H20N has two thermal cameras that provide 2× and 8× zoom and up to 32× zoom when combined. So practically speaking, when you see any hot pixels on your screen, you don’t have to fly down to dangerously low altitudes to have a closer look. Instead, all you have to do is to zoom in. This feature significantly increases the observation distance of the H20N’s thermal imaging capabilities and makes the operations faster and more efficient.
You’ll receive instant notifications in DJI Pilot when object temperatures exceed your pre-set alert values. Likewise, you can visualise a specific band of temperatures to find what is more important; and alter the colours applied to the thermal data based on particular scenarios. For instance, suppose you want to inspect the presence of human beings in a forest; you can pre-set the temperature range to 36.1°C to 37.2°C (normal body temperature of human beings), and assign a specific colour to this temperature, like red. Now, as the sensor scans the mission area, you’ll be able to visualise the presence of human beings in red colour on the screen.
Laser Rangefinder for unmatched precision
It is worth mentioning that the DJI Zenmuse H20N carries the same Laser Rangefinder that is seen in the Zenmuse H20 and H20T payloads.
With a wide detection range from 3-1200m, this rangefinder provides accurate coordinates with an accuracy of +/- 1 meter. And the PinPoint feature makes it even better; a quick tap marks an object in view and delivers its GPS coordinates. This also includes the distance from the drone and the relative height of the object. Likewise, with the Smart Track feature, users can detect and track moving objects by automatically framing shots based on the pre-marked subject while simultaneously syncing the dynamic location of the subject.
Durability and Resilience
The DJI Zenmuse H20N is IP44 rated and can be seamlessly integrated with the IP45 rated M300 RTK. The endurance of the H2ON with M300 RTK is 42 minutes and can also operate in harsh temperatures ranging from -20°C to 50°C.
Now that we know what H20N can bring to the table, we may naturally tend to compare the H20N with its predecessor in the series – the H20T. “How does it compare to the H20T – the similarities and differences? What’s the best?” You may find it out in this analysis.
Meanwhile, we can confidently conclude that the all-new DJI Zenmuse H20N is an incredibly powerful payload rugged enough to effortlessly facilitates low-light operations. The H20N’s ability to perform night missions and its amazing durability and resilience make it undoubtedly the best choice for emergency operations. We can’t wait to see how M300 users are going to leverage this tool in their public safety and security applications; H20N can efficiently assist you in searching for missing people, identifying illegal poachers, and performing night patrols at mines, construction sites and other sensitive areas.
