Dahua Technology Review and Features
Dahua is the second-largest producer of CCTV security solutions in the world with an estimated 5.6% market share.
Dahua cameras are popular for their cutting-edge smart features, easy-to-use systems, high-definition footage and excellent price-to-quality ratio. Today, we’re going to explore some of Dahua’s most popular models to find out if they warrant the popularity they’ve achieved.
Dahua DB11 Reviews
The Dahua DB11 is a doorbell camera similar to Amazon’s infamous Ring camera. As far as doorbell cameras are concerned, the Dahua DB11 is a good choice.
With 2MP resolution, the footage produced by the Dahua DB11 is clear, although sharper images are possible with other doorbell cameras. Viewing angles are 140 degrees, which is probably fine for most homes, but may not be ideal for all business environments.
Some customers have reported that they found setup difficult or annoying because the serial numbers on the parts were incorrectly labeled. However, if you’re lucky enough to have found the right numbered kit, setup is fairly simple.
The camera is wireless and can be connected to your mobile device. Both footage and audio are accessible through the Dahua app once the camera is connected to your mobile device. You can then view and communicate with anyone at your door using your phone, tablet or laptop. As far as we’ve seen and heard, once the software is properly installed and the camera is set up correctly, the connection is stable. Giving you constant protection and control.
Like most doorbell cameras, the Dahua DB11 uses passive infrared to detect motion. The camera starts recording immediately when motion is detected.
Dahua Starlight camera review
Dahua Starlight is a powerful low-illumination technology developed by Dahua for its IP camera range. Starlight comes in three performance grades, each suited for different types of low-light conditions: Basic Starlight, Advanced Starlight and Starlight.
Unlike traditional analog CCTV security systems, modern IP CCTV can collect all kinds of data which is carried over Ethernet to a Digital Video Recorder (DVR) where it can be read and processed. The additional data collected by IP cameras makes possible a range of smart features and improvements to the quality of footage collected by IP cameras. This means that IP cameras are capable of performing tasks and producing footage that are beyond the capabilities of the hardware alone.

Starlight by Dahua is a great example of this. Starlight cameras combine sophisticated sensors and lenses with state-of-the-art image signal processing. The combination of a powerful sensor and lens, supported by digital signal processing and advanced algorithms, achieves excellent video quality even in very low-light environments.
Cameras equipped with Starlight low light capability will automatically adjust in response to changing lighting conditions. As the light gets lower, the Starlight camera will begin to slow down the shutter speed to let in more light, thereby increasing photosensitivity and providing color images.
Despite being equipped with infrared (IR) capabilities, Starlight cameras can be manually adjusted to deal with extremely low-light settings without using IR. This means you can avoid the whiteout effect, which is a common problem with standard IR CCTV cameras.
In addition, Starlight cameras come with Smart Scene Adaptive technology that allows them to adapt to changing scenes. The camera automatically adjusts with dynamic range, compensates for backlight and highlights, and reacts to low light. This is useful for areas where lighting changes rapidly and frequently, such as a warehouse entrance, where opening and closing shutter doors can cause dramatic changes in lighting.
If you’re looking for even more light and color, Dahau’s latest low-light technology is Night Color, and a new version, called Night Color 2.0 Fusion, is coming soon.
Dahua LM28-F420 4K Monitor Review
For professional CCTV security operations, a high-resolution monitor is an important part of the setup. It doesn’t matter how impressive your camera’s video quality is, if your monitor can’t match them then you have a problem.
If you commit to Dahua camera systems then you are in luck because Dahua technology extends beyond cameras to monitors as well. The Dahou LM28-F420 4K Monitor delivers high-definition security footage at a great price. It is a good choice for security control panel.
This 28-inch monitor has a response time of 5ms, so it’s unlikely that you’ll notice any latency issues when monitoring your security system. It is ideal for real-time monitoring where constant vigilance is required.
Since the LM28-F420 is capable of handling high-definition footage at up to 4K, it is compatible with most Dahua cameras. Footage is clear and vibrant and easy to watch over long periods of time.
Dahua’s Discriminatory Facial Recognition Technology
Dahua’s security cameras, monitors and DVRs are technologically advanced and of good quality. However, Dahua’s operations extend to areas that violate human rights and as a result, the company has been banned by the United States.
Perhaps the most disturbing of the revelations about Dahua’s role in the persecution of Uighurs in China was the racist facial recognition technology the company developed.
Dahua initially attempted to deny the existence of the discriminatory software but investigative reporting uncovered details, many of which were found to be openly published on Dahua’s website in Chinese. The documents discussed how their software could identify so-called Uyghur-looking people caught on Dahua security cameras. Once identified, the software will send a notification directly to the local police, giving them the location where the person was last tracked.
Many of the products listed on the Chinese version of Dahou’s website come with a “real-time Uighur alert” function. This shows that Dahua is actively promoting and profiting from its discriminatory facial recognition software.
As we mentioned in this review, UNV offers Dahua’s comprehensive range of comparable IP cameras and related products. And this is without all the issues surrounding Dahua’s involvement in human rights abuses.
