What's the resolution of the photos and videos taken by Vio?

• EO Photo: 3840 x 2160 (8.51 MP). Video: 3840 x 2160 (4K@30fps).

• IR Photo: 640×512 Video: 640×512 @ 60fps (VIO F1). Photo: 640×512 Video: 640×512 @ 30fps (VIO G1).

What is the function of the USB-C port on the camera?

The USB-C port is used for upgrading the firmware of the camera.

Does Vio use Quick Release? What are the advantages of this one?

Vio will be used with the latest Gremsy Quick Release - Vio Quick Release, which will help users can plug and unplug the camera in or out from the drone as fast as possible.

Has Vio supported the third-party filter?

It does not support but we will provide the specification of the hole in front of the camera so you can customize it.

What kind of zoom does the Vio have? How much does it zoom by?

The Vio has 2 types of zoom:

• EO Zoom: 20 times optical zoom with an additional 12 times digital zoom. The optimization zoom is 30x in super-resolution zoom mode. The maximum zoom is 240x when combined with 20 times optical and 12 times digital zoom.

• IR Zoom: 1x to 8x zoom.

What is the protection rating of Vio?

Vio must first pass rigorous testing in accordance with Gremsy's quality standards before reaching the user.

Vio is dustproof to the IP5x standard.

• Make sure the gimbal is securely installed on the aircraft and the SD card slot cover is clean and closed properly.

• Make sure the surface of the gimbal is clean before opening the SD card slot cover.

What applications and what kind of specific scenarios are the Vio suited for?

The Vio is mainly designed for inspection, surveying, thermal use over long distances, thanks to 30x zoom and 4K video resolution capacity.

Is the Vio compatible with the DJI drones?

It's can be mounted on DJI drones having a suitable size but does not support the control

Which flying platforms does it suit?

The Vio only supports drones using the Mavlink base.

Is the Vio used in dual control mode (one main remote for controlling the drone, one slave remote for controlling the gimbal)?

Yes, you can use two Herelink remotes to control independently the drone and the gimbal.

What is the biggest capacity of microSD cards supported?

It supports up to 64 GB capacity, and it is recommended to use a UHS-I Speed Grade 3 microSD card.

Which apps are suitable for Vio?

Currently only compatible with the latest Android version of QGroundControl.

Is “radiometric video 60Hz” captured in a radiometric format (i.e. with temperature data included like .seq) or in a video format such as.mp4?

-> MP4 and mkv only, not in radiometric format yet.

-> Currently, Vio F1 does not support the capability to capture photos or videos in a radiometric format compatible with Flir software. We are collaborating with Flir to implement this functionality soon.

Presently, Vio F1's thermal camera is primarily for direct observation during flight rather than for thermal image analysis applications. We are actively pursuing updates to enhance its capabilities.

Do the radiometric images captured (JPEG) contain the temperature data? For example, in a FLIR compatible R-JPEG format?

-> No, it's JPEG, not RJPEG.

Do you have an SDK available for post processing captured thermal images? (similar utility to FLIR tools/DJI Thermal SDK)

-> No, we just provide SDK for the payload control and data transmision. Post processing will be on part of third party software or developer.

Can images from the RGB and Thermal sensors be captured simultaneously?

Yes, they can be capture simutaneously.

Can video feed from the RGB and Thermal sensors be streamed simultaneously?

Yes, they can be streamed simutaneously.

Do images contain any IMU metadata, e.g. pitch, roll, yaw?

-> Yes, and it already tagged including with the GPS on the EXIF file.

What is the maximum capture rate of still thermal images?

1Hz
