Starlight cameras are specialized security cameras that utilize advanced image sensor technology to capture high-quality color images even in low-light conditions. These cameras are equipped with an infrared cut filter (ICR) that automatically switches to night mode when there isn’t enough light to produce clear color images. In night mode, the IR cut filter disengages, allowing both infrared and visible light to reach the image sensor. This enhances night vision capabilities, making these cameras perfect for security purposes even under weak starlight illumination.
Originally developed by the US military for battlefield use, starlight cameras have since been adapted for a broad range of civilian applications. They are commonly used for security and surveillance due to their ability to deliver clear images without the need for artificial lighting. Available in various sizes and styles, starlight cameras are versatile and suitable for multiple uses.
To put it in perspective, the human eye struggles to identify objects when illumination drops below 20 lux. Starlight cameras, however, offer exceptional sensitivity, delivering sharper and clearer images than the human eye can perceive, even in near-zero lux conditions.
Illuminance Levels and Corresponding Environments:
- 0.0001 lux: Moonless, overcast night sky (starlight)
- 0.05–0.3 lux: Full moon on a clear night
- 3.4 lux: Dark limit of civil twilight under a clear sky
- 20–50 lux: Public areas with dark surroundings
- 100 lux: Very dark overcast day
- 400 lux: Sunrise or sunset on a clear day
- 1000 lux: Overcast day; typical TV studio lighting
- 10,000–25,000 lux: Full daylight (not direct sun)
- 32,000–100,000 lux: Direct sunlight
Starlight cameras transform your night-time surveillance by providing unmatched clarity, making them a reliable choice for any low-light environment.
