What are the different requirements for aerial drones and security surveillance cameras

The camera is widely used in the aerial UAV and security monitoring industry, and is also one of the essential main components. In terms of the use environment, the security monitoring industry has both indoor and outdoor environment, while the aerial UAV industry is mostly outdoor environment. For different use environments, what is the difference between the two requirements for the camera?

1. Environmental impact

The environment of security monitoring industry is very complex, there are day and night changes, sometimes insufficient light, sometimes too strong light, and too light too dark at the same time, indoor and outdoor excessive. Therefore, the security monitoring industry on camera requirements are mainly reflected in low illumination, wide dynamic, strong light suppression and automatic day and night switching function.

Due to the flying of aerial UAV in the air, the operator’s own skills, the change processing of the camera movement, and external factors (wind, fog, dust) are factors that affect the shooting effect, which have very high requirements on the camera’s response ability, capturing ability and picture quality resolution. The requirements of the aerial UAV industry are reflected in the functions of fog penetration, anti-shake, noise reduction and automatic day and night switching.

2, security monitoring industry requirements for cameras


(1) Minimum illumination

Minimum illuminance is a measure of how well the camera can see objects in dark environments. The lower the number, the more sensitive and better the performance of the camera.

Low illumination means that the camera can still take clear images under the condition of low light illumination. The starlight camera we talk about is a level of low illuminance camera. Therefore, it can be said that starlight camera is a camera that can still display clear color images without any auxiliary light source in the starlight environment. It is a camera series introduced to solve the image problem in low illuminance.

(2) wide dynamic

Wide motion is a technique used to make both particularly bright and particularly dark parts of a scene visible at the same time.

Wide dynamic technology can separately expose the bright and dark areas, suppress the over-bright areas, compensate for the dark areas, so that the picture as a whole presents a more clear state.

(3) strong light suppression

When the strong light (such as car lights) enters the monitoring range, the camera opens the PLC (strong light suppression) function, which can weaken the strong light part and brighten the dark light part; It can effectively suppress the halo caused by strong light source and the blurred video image, and achieve the effect of strong light suppression.

(4) Day and night switch

The security monitoring industry should meet the need to provide clear monitoring pictures in different environments day and night, and cameras should also have high-quality picture quality when lighting conditions change frequently.

According to the above requirements, Xanzhan Technology (general agent of SONY Camera movement in China) recommends SONY auto focus camera FCB-ES8230, FCB-EW9500H, FCB-EV9500M and FCB-EV9500L, which will output high-quality pictures for the security monitoring industry.

2. Requirements for cameras in the aerial UAV industry

(1) fog penetration function

When shooting in a cloudy, rainy and wet environment, fog will inevitably occur. When the functions of visual enhancement and fog penetration are enabled, the picture quality can be dynamically enhanced. In a given dynamic range, the picture will continuously adapt to and adjust the scene one pixel at a time, so that a clearer picture can be shot in a smoky environment.

(2) Anti-shaking function

The flight jitter of aerial UAV affects the picture quality of the camera, and makes the video taken by the UAV unclear. In terms of camera functions, it is necessary to select the anti-shaking function. Digital circuit is used to process the picture of electronic anti-shaking to produce anti-shaking effect and make the picture clearer.

(3) Noise reduction function

The noise reduction function of aerial UAV camera is the function of the pointer to optimize and eliminate the noise. Long exposures produce noise, which occurs mostly in low ISO night shots, with a few jumbled highlights in the dark night sky of the image. When the noise reduction function of the drone camera is enabled, the images taken will be clear and smooth, and high-definition images will be obtained.

(4) Automatic day-night conversion function

Automatic day-night switching is essential in the aerial drone industry. In low-light environments, the camera assembly automatically switches from day mode to night mode, removes infrared filters, and improves sensitivity so that it can capture clear images at night.

FCB-ER8530, FCB-EV7520, FCB-EV7100 are SONY autofocus cameras commonly used in aerial UAV industry, which can cope with the complex external environment of the industry.

After the above comparative discussion, whether it is security monitoring or aerial photography UAV industry, the requirements for the camera should be relatively clear, and the choice of camera will be confident.
