To document polar bears in their natural icy habitat, spy cameras able to withstand -40°C temperatures — and disguised as floating ice (‘iceberg cam’), snow (‘snow cam’), block of ice gliding on skis (‘blizzard cam’), snowball (‘snowball cam’), snowdrift (‘drift cam’) — are used. Apparently the disguise is not good enough and the polar bears see right through the deception.
