DarkFighter 2.0:
Replaces the dual-sensor system with highly efficient single-sensor designs.
After discussing what the DarkFighter technology of Hikvision is, let’s take a look at its competitor, the WizColor technology from Dahua. The key function of WizColor technology is essentially the same as DarkFighter as it is designed to provide high quality color vision in low light conditions. This technology focuses on providing detailed color vision, which is essential for tasks such as facial recognition, vehicle identification, and situational awareness. For this, the WizColor technology uses advanced sensors, white light illumination, and AI-powered image processing. Some of the key features of this technology include:
Full-color imaging
High-sensitivity sensors
Large aperture lenses
Supplemental white light
Advanced image processing
Wide dynamic range

At this point, you should already have a general idea regarding what Hikvision technology WizColor and Hikvision DarkFighter is. So, let’s make a comparison between these two competing technologies. Following is the comparison of Hikvision DarkFighter 2.0 vs. Dahua Technology WizColor.
The first area where we shall be making a comparison between Dahua technology and hikvision is in the aspect of low-light imaging. Since both DarkFighter and WizColor feature advanced low-light imaging, it would only be fair to compare them on low-light imaging. Following is the comparison between these brands.
Hikvision DarkFighter 2.0
Utilizes advanced large-format CMOS sensors with exceptional sensitivity to low light (as low as 0.002 lux) to produce full-color, high-resolution images.
Dahua WizColor
Uses high-sensitivity sensors and supplemental white light LEDs to deliver full-color images even in near-total darkness.
Another key area of comparison between Hikvision DarkFighter 2.0 and Dahua WizColor is in the sector of AI Integration. This is because both of these technologies feature advanced AI features. The key areas of comparison include:
Hikvision DarkFighter 2.0
It offers deep learning-based analytics: object detection, face recognition, and behavior analysis.
Dahua WizColor
Equipped with AI-driven platforms such as WizMind and WizSense, enabling real-time analytics of object classification, perimeter protection, and event detection.
The third aspect we are going to compare is energy efficiency. This is because energy efficiency is an integral aspect of advanced technology, and the higher the energy efficiency without the compromise of features, the better it is for you. So, in this regard, the following is the comparison of Dahua Technology WizColor and Hikvision DarkFighter in terms of energy efficiency.
Hikvision DarkFighter 2.0
Designed with advanced sensors that maximize light sensitivity while minimizing power consumption.
Dahua WizColor
Uses white light LEDs for nighttime illumination
Following energy consumption, the next aspect we shall discuss is motion handling. This is because the ability to capture clear video and images of moving targets is essential in low light, especially in areas such as financial buildings and roads. Good motion handling allows you to capture the moving targets in detail. Since both brands have advanced tech for this, the following is a comparison between Dahua technology WizColor and Hikvision Darkfigher in regards to motion handling.
Hikvision DarkFighter 2.0
Features advanced motion detection algorithms and dynamic noise reduction that handle moving objects with exceptional clarity, even in low-light conditions.
Dahua WizColor
Utilizes AI-enhanced motion detection to achieve smooth tracking and continuous color imaging of moving subjects under different lighting conditions.
The next sector is in the application of these technologies. Both WizColor and Darkfioghter have their own sector where they perform the best, and depending on the specific uses, one can win over another. So, keeping this in mind, let's take a brief look at the comparison.
Hikvision DarkFighter 2.0
Perfect for large-scale, high-security scenes like airports, railways, and industrial areas.
Dahua WizColor
Perfect for urban surveillance, retail spaces, and traffic monitoring where color details are critical.
After discussing the application of these technologies, the next aspect we shall compare is the frame rate provided by these technologies now, although both Dahua technology WizColor and Hikvison do have some differences. They are different in that what distinguishes them from each other is as follows:
Hikvision DarkFighter 2.0: Allows high-frame rate recording, such as 60 fps, for smoothly and clearly viewing fast-moving targets, especially in low light.
Dahua WizColor: Provides standard frame rates optimized for Full-Colour imaging; not necessarily high frame rates across all models in the same way DarkFighter 2.0 does.
The final feature we shall make a comparison with is the WDR. This is featured to deal with the complicated lighting condition, especially ones with huge differences in brightness; this aims at clear details of both dark and bright regions. The good thing here for you is that WizColor and DarkFighter do possess this feature, although each with its specific features. Some of the differences include:
Hikvision DarkFighter 2.0:
This section features ultra-wide dynamic range, up to 140 dB, to handle the extremely differentiated backlight and shade areas in a variety of scenes.
Dahua WizColor:
Provides excellent WDR performance but generally falls within 120 dB, making it less effective in handling severe lighting disparities.
At this point, we have reached the end of the comparison. But just to make it even more clear, the following is the tabular representation of the differences.
