Autel EVO II 640T V3 and EVO MAX 4N, as the leading commercial drone platform among Autel drones, have powerful flight performance and camera performance, bringing reliable drone aerial solutions to multiple industries.We will illustrate the night vision comparison of thermal camera drones and starlight camera drones. This article takes Autel EVO II 640T V3 and EVO MAX 4N drones as examples.
Autel EVO II 640T V3 VS EVO MAX 4N: Overview
Autel EVO II 640T V3 has dual camera sensors, supports 8K video and 640*512 thermal imager, Autel Explorer App comes with Autel IRPC tool, which can be used to identify and analyze thermal images.
EVO MAX 4N has a multi-sensor camera that supports 50MP wide-angle camera, 640*512 thermal imager, 23MP starlight camera and laser rangefinder. The starlight sensor will take clearer shots at night, even in extremely low-light environments.

The night imaging of Autel EVO II 640T V3 relies on the thermal imager, and the night imaging of EVO MAX 4N can rely on the thermal imager and starlight camera.
The principle of thermal imaging at night is that thermal cameras perceive thermal infrared, detect differences in thermal characteristics, and identify different things in the environment. Starlight cameras are near-infrared imaging that create images by capturing reflected or absorbed light.

The main advantage of thermal infrared is that it can create images in total darkness while capturing objects with thermal differences unaffected by factors such as smoke, fog and dust.
Near-infrared technology can produce clearer images than thermal imaging, but it must have certain light source conditions. Near-infrared images can fully visualize all objects and refine more details.
