The Foxeer Cat Night 3 is a high-end camera designed primarily for operation in poor light conditions. It has high light sensitivity while maintaining low noise levels. This makes it perfect for flying in twilight or at night. To increase the received light, the camera does not have an IR filter, so it is sensitive even to IR illumination 850nm. The camera has its own OSD and a VSENS pin, thanks to which it can display the power supply voltage. This is particularly useful for FPV pilots of conventional aircraft that do not often use a controller.
Due to the lack of an IR filter, the camera is designed for flying primarily at night. During the day, the image is purple.
