Night vision types — IR, Smart Light, Color24 and Dual Light

What does a camera really see at night? A comparison of technologies — classic IR (black & white), Smart Light (color with floodlight), Color24 (color in minimal light) and Dual Light (combination). When to choose which?

The most common customer question: "Does the camera see in color at night?" The answer is not simple — it depends on the night vision technology. This article explains the 4 main variants in PATRONUM cameras and when each makes sense.

1. Classic IR (infrared) — black & white image

The most common and longest-used technology. The camera has IR LEDs that emit infrared light — invisible to the human eye. The image is displayed in black and white.

  • Long range (15–80 m depending on the model)
  • Works in complete darkness
  • Does not disturb surroundings (IR is not visible)
  • Loses colors (you cannot tell the color of a car or clothing)
  • Reflections from fog, rain, dust

When to use: outdoor environments, parking lots, warehouses, gardens. The most affordable option.

2. Smart Light (Warm Light) — color with floodlight

Instead of (or alongside) IR LEDs, the camera has a white LED floodlight. It activates on motion detection, illuminates the scene and the camera captures a color image.

  • Color image even in the dark (you can recognize license plates, colors, faces)
  • The floodlight deters unwanted visitors
  • Acts as security lighting
  • Also lights up surroundings (neighbors, residential areas — be careful)
  • Range about 20–30 m (less than pure IR)

When to use: house entrance, courtyard, garden by the house. Suitable where motion = visitor and you don't mind the camera projecting light.

3. Color24 (Full Color, Starlight) — color without floodlight

Technology based on an extremely sensitive sensor (often Sony STARVIS) + a wide-aperture lens (f/1.0 to f/1.6). The camera can capture a color image with minimal ambient light (street lamp, moon, starlight reflection).

  • Color image without illumination
  • Does not depend on IR/floodlight
  • Quiet, discreet — people don't notice it's night
  • Needs at least minimal ambient light (street lamp, terrain reflection)
  • In absolute darkness the image gets noisy or goes black
  • Higher price

When to use: urban environment, parking lots with lamps, town squares, sidewalk by a house with street lighting. Our camera range with the Sony STARVIS sensor.

4. Dual Light (IR + Smart Light) — hybrid

The camera has both technologies at once and decides itself which to use:

  • By default = IR (black & white, energy-efficient)
  • On motion detection = white LED turns on (color)

Benefits of both — energy saving + color image during events.

  • Most flexible option
  • Economical operation (floodlight only on motion)
  • Color recording of important events
  • Higher price and consumption
  • More complex configuration

When to use: entrance gate, cash register, critical points where you always want to record in color, but you don't want the floodlight running 24/7.

How to tell which one a camera has?

In product specifications, look for:

  • IR range 30 m → classic IR
  • Smart Light / Warm Light / Active Deterrence → white floodlight
  • Color24 / Full Color / Starlight / 24/7 Color → high sensitivity
  • Dual Light / Hybrid Light → IR + white combination

If you're unsure which to choose, try our camera system configurator — it recommends a model based on your specific environment.
