Full Color 4K Resolution Even in Dark Scenes with Dahua Cameras
, by Armia Ghali, 4 min reading time
Low light. Yes, we've all encountered this situation. It's a common challenge for installers and end users. Low-light (or nighttime) footage from traditional security cameras is often black and white, blurry, or heavily pixelated, which isn't ideal for retrieval in the event of an incident.
When choosing the right camera for low-light scenarios, consider 4K cameras—the latest industry trend that is gradually becoming a standard surveillance solution. According to a recent report, the 4K video surveillance market size is expected to grow annually, primarily due to the increasing demand for public safety, the rapid development of 4K technologies, and the introduction of more affordable cameras.
4K in a nutshell
4K cameras have a resolution of 3840 x 2160 pixels, which amounts to a whopping 8 million-plus pixels. For comparison, a 4K security camera has four times the number of pixels of a 1080P camera (see image below), allowing it to produce clearer images with significantly higher resolution. If you compare the image quality of 4K cameras with that of traditional non-HD security cameras, you'll immediately realize that the significant increase in resolution makes the difference between "blurry" and "clear" details in the image.
Dahua Full-color 4K Cameras
The Dahua Full-color 4K camera utilizes Dahua's proprietary Full-color technology and delivers enhanced images and surveillance footage 24/7. The 1/1.2" image sensor (currently Dahua's best low-light IP camera sensor) provides 110% more pixels than a conventional 8MP sensor. Furthermore, the large F1.0 aperture allows more available light to pass through, doubling the amount of light the sensor can receive!
AI Features
Dahua's full-color 4K cameras are packed with AI features that meet various user surveillance needs. Perimeter Protection accurately detects people and vehicles in the scene. SMD 3.0 reduces false alarms and increases the detection distance. AI scheduling allows users to flexibly set various AI functions based on their preferred time. Other AI features include People Counting (8 lines) and Queue Management (4 lines).
Conclusion
Gone are the days of black-and-white surveillance video footage of scenes in the dark. Darkness or night shouldn't be an obstacle to capturing razor-sharp color images of the scene. Thanks to rapid technological development and innovation, intelligent devices like Dahua Full-color 4K cameras can effectively solve this problem, delivering clear and color-accurate images of the scene, useful for accurate video analysis.
