Starlight cameras are security cameras that use image sensor technology to produce good quality color images in low light conditions. The camera features an IR cut filter (ICR) that switches the device to night mode when insufficient light is available to reproduce good quality color images. While in night mode, the IR cut filter disengages, allowing infrared and visible light to reach the image sensor. This feature is beneficial for security purposes as it allows for improved night vision in low light conditions, even when there is only weak illumination of starlights.
The sensors of these cameras make photography in extremely low-light possible by increasing the light sensitivity up to, 2000mV or more per 1µm2. these cameras slow down the cameras’ electronic shutter speed to capture more light in order to record in color. It involves both hardware and software to work together to render impeccable picture quality in challenging light conditions. Both special sensor and special algorithms work hand in hand to product colored images in low light conditions.
These cameras are easy to install and equipped with video analytics to enrich performance and data management including digital noise reduction, intelligent video analytics, remote access, etc. It provides high definition colored images in the dark, which is a result of this technology combined with the intelligent auto exposure. This enables the camera to adapt to the low light conditions and produce images which comparatively clearer as compared to the conventional cameras.
This camera will provide both black and white and colored night vision depending upon the lighting conditions. If it is too dark, it will render black and white images. Since the sensors of the Starlight cameras are more sensitive, they provide better image output than any average security camera.
Starlight Camera vs Infrared Camera: What is the difference?
People often confuse the camera with the Infrared cameras. Starlight is better than Infrared in terms of image output. However, nowadays most of the cameras combine both Starlight and Infrared technology. The major difference between the Starlight technology and Infrared is that the former give colored images even in low lighting conditions, while Infrared renders images in dark as well. IR cameras have to use the attached Infrared sensors to get visible images at night.
Benefits of Starlight Camera
When combined with video analytics software, Starlight cameras offer high quality image output. Here are a few advantages that Starlight cameras have over the average cameras.
- Better level of security since Starlight cameras can offer clear images even in night. So if the trespasser switches the lights off to hide, he can still be captured on the camera.
- Provides video analytics and color filtering down to 0.0001 lux~0.0003 lux.
- When other cameras show no images at all in dark areas, Starlight cameras give detailed black and white images.
- It improves low light performance of the CCTV cameras to provide round the clock surveillance.
You know, human eyes could hardly identify anything when the illumination goes below 20 Lux. Well, the starlight cameras, with exceptional starlight sensitivity, could give you sharper and clearer images than your eyes could see even in almost 0 Lux conditions.
|Illuminance (lux)||Surfaces illuminated by|
|0.0001||Moonless, overcast night sky (starlight)|
|0.05–0.3||Full moon on a clear night|
|3.4||Dark limit of civil twilight under a clear sky|
|20–50||Public areas with dark surroundings|
|100||Very dark overcast day|
|400||Sunrise or sunset on a clear day|
|1000||Overcast day;typical TV studio lighting|
|10,000–25,000||Full daylight (not direct sun)|
How Do Starlight Cameras Work
These cameras are a type of night vision camera that uses starlight to provide imaging in low light conditions. Starlight cameras work by collecting and amplifying the light from stars, moon, and other objects in the night sky to provide imaging in conditions where traditional night vision cameras would not be able to function.
In fact, it is the crucial starlight sensor technology and the sophisticated noise suppression that result in exceptional sensitivity and clear night vision.
Like the retina of the human eyes, the starlight sensor is sensitive to light. The amount of light the sensor gets will determine the image quality.
Better than human eyes, the starlight cameras use larger size sensors, wider aperture and reduces the shutter speed to collect enough light for the human face and plate number identification. And that’s the way how they provide high-quality and clear images when human eyes couldn’t see anything.
Where to install Starlight CCTV cameras?
As the definition itself suggests, Starlight CCTV cameras provide clear images in low light conditions, which makes them useful for outdoor purpose. There are places like garages, porch, parking lot, etc. that cannot be brightly lit all the time. That’s where Starlight cameras come to use. They provide greater visibility detecting trespassing, theft, vandalism, etc. with its smart video analytics tool.
