Even in the glaring sunlight, our dual-sensor PTZ can more accurately identify surfers in the sea thanks to the dual recognition feature of the thermal imaging camera, maximising their safety in big waves.

Why do rolling waves in a sunny daytime often appear as "hot" colors in the thermal camera view?
The rolling motion of the waves constantly brings fresh water up to the sunlight. The crests of the waves are exposed directly to the sun and are heated faster than the lower, shaded areas. This causes the crests to radiate more infrared (IR) energy, which the thermal camera detects as warmer or "hot" colors. Rolling waves churn up the surface, mixing the warmer water on top with cooler water from below. This action keeps the water at the surface consistently warm and contributes to a more uniform “hot” appearance on the thermal display. Meanwhile, rolling waves create angles that can reflect more of the sun’s IR radiation directly into the thermal camera which enhance the "hot" appearance of the wave .
