Demand for drones has risen sharply in recent years. A drone‑mounted camera is installed at an appropriate position on the gimbal. It transmits captured video signals to the video‑transmission transmitter fitted on the drone. The video signal is then sent to the ground receiving system, which outputs signals via SDI / HDMI to display devices. Operators are therefore able to view real‑time aerial footage from the drone camera. For this reason, drone‑mounted cameras are deployed across a wide range of sectors. What important functions should such cameras feature? Below are insights shared by Kaimorui.

Key Functions for Drone‑mounted Cameras

Fog‑penetrating Function

When shooting under rainy, humid or foggy weather conditions, fog often degrades imaging performance and prevents ideal output. Therefore, drone cameras should be equipped with a fog‑penetrating feature. When visual enhancement and fog‑penetration are activated, image quality is dynamically improved. Within a given dynamic range, the scene is continuously adjusted pixel‑by‑pixel, delivering relatively clear footage even in heavy haze or smoky environments.

Noise Reduction Function

Noise reduction optimizes and eliminates image noise. Noise artifacts mostly appear during long‑exposure night‑time shooting at low ISO values, showing as scattered bright speckles across dark areas of the frame. This happens when the image processor is overloaded by slow shutter speeds, causing certain pixels to malfunction. With noise reduction enabled, output images become smoother and sharper for high‑definition results.

Image Stabilization Function

Vibration during drone flight blurs captured video. Accordingly, image stabilization is an essential requirement for drone cameras. Electronic image stabilization applies digital processing to offset shake and deliver clearer footage.

Auto Day‑Night Switch Function

Widely deployed in diverse scenarios, drone cameras must deliver clear monitoring footage around‑the‑clock under varying lighting conditions while preserving good image quality. An auto day‑night switch is indispensable. In low‑light environments, the camera module automatically switches from day mode to night mode by removing the infrared cut filter to boost sensitivity and capture clear night‑time images.

To sum up, drone‑mounted cameras serve extensive application fields, including digital city construction, urban planning, land‑resource surveys and law‑enforcement, mineral‑resource exploitation monitoring, forest‑fire prevention, flood control and drought relief, environmental monitoring, border‑surveillance, military reconnaissance, police and fire‑service monitoring, plus many other special‑industry drone operations.
