Imaging Performance

Starlight Camera

Starlight cameras deliver relatively clear color images under low-light conditions with faint ambient light such as starlight and moonlight. They feature ultra-high photosensitivity, with a typical minimum illumination ranging from approximately 0.001 Lux to 0.002 Lux.

For instance, in a park at night lit only by scattered street lamps and starlight, a starlight camera can capture the hues and outlines of objects, enabling users to distinguish fine details including clothing colors of pedestrians and vehicle tones.

Full-Color Camera

Full-color cameras are designed to output color footage round the clock under all lighting conditions, both daytime and nighttime. Even in extremely dim surroundings, built-in supplementary lighting modules (white light fill light in most cases) sustain full-color video output.

Take underground parking lots as an example: relying on its fill light system, a full-color camera maintains color visuals at all times, allowing operators to clearly identify vehicle colors, license markings and people’s movements across parking bays.

Conventional Infrared Camera

Conventional infrared cameras produce color images under sufficient daylight. Once night falls or ambient light diminishes, the built-in infrared LEDs activate for auxiliary illumination. Due to the inherent imaging characteristics of infrared light, the footage switches to monochrome (black-and-white).

In an unlit alleyway after dark, such cameras cannot record any color information; only grayscale outlines of people and objects are visible on the monitoring screen.

Working Principles

Starlight Camera

Starlight cameras enhance faint light capture capability through hardware configurations including large-aperture lenses and high-sensitivity image sensors. Optimized sensor performance enables the device to collect adequate light data even in poor lighting, converting optical signals into distinct electrical signals for vivid imaging.

Full-Color Camera

Apart from excellent low-light sensitivity, full-color cameras are equipped with an intelligent fill light system. When ambient brightness is insufficient, the fill light turns on to supply visible light, ensuring the image sensor receives enough light for color reproduction. Meanwhile, dedicated image processing algorithms are optimized for color restoration, guaranteeing premium full-color output across varying illumination levels.

Conventional Infrared Camera

In low-light environments, conventional infrared cameras automatically switch on infrared lamps. The infrared radiation emitted is invisible to the human eye yet detectable by the camera’s image sensor. After infrared light reflects off object surfaces and is received by the sensor, signals are converted into black-and-white video streams to realize night surveillance, subject to the spectral properties of infrared rays.

Application Scenarios

Starlight Camera

Ideal for locations requiring nighttime color monitoring where additional fill lights cannot be installed.

Nature reserves: Used to track nocturnal wildlife activities; harsh supplementary lighting is forbidden to avoid disturbing animals, and starlight cameras can record animals’ natural appearances and behaviors without light pollution.
Ancient architectural complexes: Provides color surveillance footage overnight without spoiling the aesthetic nightscape of historic buildings for heritage protection purposes.

Full-Color Camera

Widely deployed in scenarios where continuous color video footage is mandatory:

Retail stores: Captures clear indoor details throughout business hours and after closing time, including merchandise colors and display layouts.
Residential community gateways: Accurately records vehicle colors and facial features of incoming and outgoing residents, facilitating property management and public security control.

Conventional Infrared Camera

Suitable for night monitoring tasks with low color requirements, where only object outlines and movements need to be tracked:

Warehouse perimeters: Primarily used to detect illegal intrusions; black-and-white infrared imaging fulfills basic monitoring demands, and invisible infrared illumination boasts strong concealment.

Price Comparison

Starlight Camera

Equipped with high-performance image sensors and premium optical lenses, starlight cameras command a relatively higher price. Their cost is generally 30% to 50% higher than that of conventional infrared cameras, with exact prices varying by brand and functional configurations.

Full-Color Camera

Thanks to sophisticated fill light systems and advanced image processing technologies, full-color cameras are also priced at a premium. High-end models integrated with intelligent brightness adjustment, ultra-high definition and other versatile functions may cost 1.5 to 2 times as much as standard infrared cameras.

Conventional Infrared Camera

Boasting mature, well-established technology, conventional infrared cameras are affordable and the most mainstream surveillance camera option, perfectly suited for cost-sensitive monitoring projects.
