In the realm of modern security camera systems, the demand for effective surveillance in challenging low light conditions has grown exponentially. The ability to obtain crystal-clear images during the night or in areas characterized by minimal illumination has become an indispensable feature. Among the fundamental specifications of camera systems, the term "low light sensitivity" emerges as a critical factor.

1. Grasping the Concept of Illuminance (Lux)

Illuminance, quantified in Lux, stands as the yardstick to measure a camera's sensitivity to light. Lux signifies the level of lighting under which a camera can capture images. Lower Lux values translate to cameras that can produce clear images in conditions of lesser illumination. For instance, with an aperture set at F1.2, a camera's low light sensitivity of 0.02 Lux/F1.2 empowers it to deliver clear images even in dimly lit settings.

2. Strategies for Optimizing Low Light Photography

Differentiating between color and black-and-white CCD cameras is pivotal when it comes to mastering low light photography. These types of cameras demand distinct minimum illumination thresholds, as highlighted below:

Minimum Illumination for Various Camera Types:

- Color Cameras: Standard Lux

- Black and White Cameras: Lower Lux

The spectrum of visible light spans from 380nm to 780nm. CCD sensors possess an ultraviolet-absorbing transparent electrode, rendering them impervious to ultraviolet light. Ordinary color cameras feature red, green, and blue filters, limiting their capacity to detect infrared light. In contrast, black and white CCD cameras can perceive both visible and infrared light.

Achieving Crisp Images in Dim Conditions: OHWOAI's Ingenious Solutions

(1) Regular Low Light Black and White CCD Camera + Infrared Lighting

By strategically installing infrared lights within the surveillance area, these lights emit infrared rays imperceptible to the human eye. Consequently, black and white CCD cameras can capture images even when confronted with low light circumstances.

(2) Color-to-Black-and-White Conversion Camera + Infrared Lighting

The dynamic transition from color to black and white mode underpins the functionality of this camera type. In situations characterized by limited illumination, these cameras leverage the heightened sensitivity of black and white imaging to infrared light. Seamless integration with infrared lighting necessitates meeting the minimum illumination prerequisite of the infrared source.

(3) Infrared Low Light Color Camera

Incorporating a design attuned to infrared sensitivity, infrared low light color cameras outshine their regular counterparts. This enhancement results in a sensitivity that surpasses traditional cameras by over fourfold, enabling them to operate efficiently even in environments devoid of light.

(4) Slow Shutter Speed Cameras

Under the umbrella of frame accumulation cameras, slow shutter speed cameras exhibit their prowess by capturing multiple frames of marginally blurred images attributed to diminished lighting. Employing SLOWSHUTTER technology, these images amalgamate into a clear depiction. This technology facilitates capturing images at an illumination level of 0.008 Lux/F1.2, rendering them invaluable for settings such as museums, nocturnal wildlife observation, and nighttime military coastline surveillance.

(5) Ultra-Low Light Cameras

Harnessing the potential of EXVIEWHAD technology, ultra-low light cameras revolutionize sensitivity. Demonstrating the capability to achieve color illumination levels of 0.05 Lux and black-and-white illumination levels ranging from 0.003 to 0.001 Lux, these cameras emerge as pioneers in low light conditions. By collaborating with dedicated infrared devices, these cameras boast the capacity to produce high-definition black-and-white imagery even when exposed to a Lux value of 0.
