Field Observation Node (FON)
The Field Observation Node (FON) is a compact, portable system for continuous 360° video documentation in remote environments. Designed around the DJI Osmo 360 action camera, it captures high-resolution footage with exceptional low-light performance. It is also equipped for timelapse recording, enabling long-term monitoring of field sites such as Hessdalen and other locations of scientific interest.
We have 3 kits
We maintain three Kits instead of just one. This gives us several important advantages in the field:
Cover More Ground
Three teams can cover more area and capture events from different angles.
Enable Manual Triangulation
Multiple teams observing the same object can triangulate its distance, altitude, and speed.
Training & Practice
One kit can be used to create controlled test scenarios (e.g., moving a flashlight at different speeds or distances). The other teams practice identifying and measuring, learning to estimate motion, distance, and size in the field.
Content in the FON kit:
DJI Osmo 360 actionkamera, Camera Protective Bag, Lens Cleaning Cloth, 3 x batteries, adapter mount, selfie stick, rubber lens protector, mini tripod,
2 x 512 microSD cards, cardholder, a short USB-C cable, a long USB-C cable, 20,000mAh powerbank, a tech bag and a bag for all the equipment.
Additional equipment:
In kit #2: a flashlight.
In Kit #3: binoculars and a charger (2x USB-A, 4x USB-C)
