The Reolink Argus 4 Pro does not use IR night vision. Instead, this Reolink solar camera uses ColorX technology with an F/1.0 aperture to deliver full-color footage in the dark. Here is how it works and why it matters.
Does the Reolink Argus 4 Pro Have IR Night Vision?
No. The Reolink Argus 4 Pro does not have traditional infrared (IR) night vision. Instead, it uses Reolink’s ColorX technology, a combination of a large 1/1.8″ image sensor and an ultra-wide F/1.0 aperture to capture full-color video in low-light and near-dark conditions without IR LEDs.
This is a deliberate design choice that sets the Argus 4 Pro apart from most other Reolink solar cameras and battery-powered security cameras on the market.
What Is Traditional IR Night Vision and Why Did Reolink Remove It?
Most security cameras, including many in the Reolink solar camera lineup, use infrared LEDs to illuminate a scene in darkness. The camera sensor picks up this infrared light and produces an image, but because IR light is outside the visible spectrum, the result is always a grainy, black-and-white image with limited detail.
IR night vision has two additional drawbacks for battery-powered cameras:
- IR LEDs are power-hungry. Running them continuously at night significantly reduces battery life.
- They produce no visible deterrent effect an intruder cannot see the IR illumination at all.
Reolink removed IR LEDs from the Argus 4 Pro entirely to address all three of these limitations: image quality, battery efficiency, and deterrence.
How Does ColorX Work on the Reolink Argus 4 Pro?
ColorX is Reolink’s proprietary low-light color imaging system. It achieves full-color night vision through hardware rather than supplemental lighting, using two key specifications:
1/1.8″ CMOS Image Sensor
The sensor size in a camera determines how much light it can physically collect. The Argus 4 Pro’s 1/1.8″ sensor is significantly larger than the 1/2.8″ or 1/3″ sensors found in most budget security cameras. A larger sensor captures more light per frame, which directly translates to cleaner, brighter images in low-light conditions.
F/1.0 Aperture
The F/1.0 aperture on the Argus 4 Pro lens is exceptionally wide for a security camera. Aperture controls how much light enters through the lens, and an F/1.0 lens admits roughly four times more light than a standard F/2.0 security camera lens. Combined with the large sensor, this means the camera can produce usable color images in environments with very little ambient light, such as a dimly lit driveway or a street-lit front porch.
Reolink Argus 4 Pro: ColorX vs Traditional IR Night Vision
Here is a direct comparison of how ColorX performs against traditional IR night vision across the features that matter most for a Reolink solar camera:
| Feature | Traditional IR Night Vision | Reolink ColorX (Argus 4 Pro) |
| Image Color | Black & white only | Full color |
| Light Source | Infrared LEDs (invisible) | Natural / ambient light |
| Spotlights Needed | No (IR handles darkness) | Optional (motion deterrent) |
| Sensor Size | Typically 1/2.8″ or smaller | Large 1/1.8″ CMOS |
| Aperture | Typically F/1.6 – F/2.0 | Ultra-wide F/1.0 |
| Battery Impact | Higher drain (IR LEDs active) | Lower drain (no IR LEDs) |
| Detail in Low Light | Grainy, flat | Sharp, color-accurate |
| Intruder Deterrence | None (IR is invisible) | Optional warm spotlight |
Does the Reolink Argus 4 Pro Have Any Lights at All?
Yes. The Argus 4 Pro is equipped with 6500K warm white spotlights that can be triggered by motion detection. These are not required for the camera to see in the dark ColorX handles that. The spotlights serve a different purpose: active deterrence. When someone approaches your property at night, the spotlight activates, making it clear the area is monitored and discouraging further movement.
You can configure the spotlights independently of recording. Options typically include always-off (ColorX only), motion-triggered, or scheduled activation, giving you full control without sacrificing battery life unnecessarily.
How Does Removing IR Affect Battery Life on This Reolink Solar Camera?
Removing IR LEDs is one of the primary reasons the Reolink Argus 4 Pro claims 30% longer battery life than previous-generation Reolink solar cameras. IR LEDs draw significant power whenever they are active, which in a typical installation means every night, for hours at a time.
By relying entirely on passive light collection through the sensor and aperture, the Argus 4 Pro avoids this overnight power drain. Combined with the 5000 mAh battery and compatibility with the Reolink Solar Panel 2 (6W), the camera is designed to run indefinitely in most outdoor conditions without manual recharging.
Who Should Choose the Reolink Argus 4 Pro for Night Vision?
The ColorX system on the Argus 4 Pro is the right choice if:
- You want to identify clothing colors, vehicle colors, or facial features in night footage, but black-and-white IR footage makes this difficult or impossible.
- You care about battery efficiency; eliminating IR LEDs extends runtime significantly.
- Your installation location has some ambient light, such as a street lamp, porch light, or garden light nearby, which gives ColorX enough input to produce excellent results.
It is worth noting that in true zero-light environments (a completely dark rural location with no ambient light whatsoever), the spotlight will be needed. ColorX is not night-vision goggles; it amplifies available light rather than creating its own. In most residential settings, however, there is always some ambient light present, and ColorX performs very well.
Frequently Asked Questions
Does the Reolink Argus 4 Pro switch to black and white at night?
No. Unlike cameras with IR night vision, the Argus 4 Pro stays in full color at night using ColorX technology. It only produces color footage, day and night.
Can I add IR night vision to the Reolink Argus 4 Pro?
No. The camera does not have IR LEDs and there is no add-on option. It is designed exclusively around ColorX. If you need traditional IR night vision, you would need a different Reolink model.
Is ColorX better than IR night vision?
For most residential use cases, yes. ColorX produces full-color footage with more usable detail for identification purposes. IR night vision produces black-and-white footage and drains more battery. The only scenario where IR has an edge is in complete, zero-ambient-light darkness.
Does the Reolink Argus 4 Pro work without the spotlight at night?
Yes. The spotlight is optional and is used primarily as a deterrent. ColorX produces color footage using only available ambient light it does not require the spotlight to see in the dark.
How does the Reolink Argus 4 Pro compare to other Reolink solar cameras for night vision?
Most other Reolink solar cameras use traditional IR night vision and produce black-and-white footage at night. The Argus 4 Pro is one of the only models in the Reolink lineup to offer full-color night vision through ColorX, making it the premium option for image quality in low-light conditions.
Conclusion
The Reolink Argus 4 Pro does not use IR night vision and that is not a limitation. It is a deliberate upgrade. By replacing power-hungry IR LEDs with a large 1/1.8″ sensor and an F/1.0 aperture, Reolink’s ColorX system delivers full-color night footage that is sharper, more detailed, and more useful for identifying people and vehicles than traditional black-and-white IR imagery.
For anyone evaluating a Reolink solar camera for outdoor home security, the Argus 4 Pro’s approach to night vision is one of its strongest technical advantages especially when combined with the battery efficiency gains that come from eliminating IR LEDs.
