Get realistic image quality even in dark environments with Dahua Full-color 4K cameras

Get realistic image quality even in dark environments with Dahua Full-color 4K cameras
The Dahua Full-color 4K camera utilizes Dahua’s very own Full-color technology, delivering enhanced images and surveillance footages 24/7.
Low-light condition. Yes, we’ve all experienced such environment. It has been a prevailing monitoring challenge for installers and end users. Images taken from scenarios with dark lighting (or during nighttime) using traditional surveillance cameras are often black and white, fuzzy or heavily pixelated, which is not ideal for backtracking in case of an event.
 
When choosing the right camera for scenarios with low illumination, you can consider 4K cameras – the latest craze in the industry that is gradually becoming a mainstream monitoring solution nowadays. In fact, according to a latest report, the 4K video surveillance market size is expected to grow at 9 percent CAGR (compound annual growth rate), which is primarily driven by the increasing demand for public safety and security services, as well as the speedy advancements in 4K technologies and more affordable cameras on the market.
 

4K in a nutshell

 
4K cameras have resolution of 3840 x 2160 pixels, which results to a whopping 8 million plus pixels. In comparison, 4K surveillance camera has 4 times the number of pixels of 1080P camera (see illustration below), allowing it to produce clearer images with significantly higher resolution. In fact, if you try to compare the image output of 4K cameras to traditional non-HD surveillance cameras, you’ll immediately realize that the significant increase in resolution reflects the difference between “ambiguous” and “clear” details in the image.
 

Dahua Full-color 4K cameras

 
The Dahua Full-color 4K camera utilizes Dahua’s very own Full-color technology, delivering enhanced images and surveillance footages 24/7. It adopts 1/1.2” image sensor (currently Dahua's best low-light IPC sensor) that provides 110 percent pixel size increase compared to conventional 8MP sensor. What’s more, its F1.0 large aperture can capture more available light and the maximum light energy that the sensor can receive is increased by 2 times!
 

AI functions

 
The Dahua Full-color 4K cameras are packed with AI functions that can accommodate various monitoring needs of users. Perimeter Protection accurately detects targets in the scene. SMD 3.0 reduces false alarms and increases the detection distance. AI Schedule allows users to flexibly set different AI functions based on their preferred time. Other AI functions include people counting (8 rules) and queue management (4 rules).
 

Takeaways

 
Gone are the days of potato-quality black and white surveillance video footages of scenarios under dark environments. Darkness or nighttime should not be a hindrance in capturing clear color images of the scene. With rapid technological development and innovation, intelligent devices like the Dahua Full-color 4K cameras can effectively solve this issue, providing clear and vivid image of the scene that is beneficial for accurate video analysis.
