what is 4K Security Camera

Since 1080P full HD technology has been widely used in video surveillance, television broadcasting, smartphone, HD technology becomes common in our daily life. People are eager to pursue much higher resolution, many television manufacturers launched 4K ultra HD TV into market, meanwhile a few IP camera manufacturers released 4K ultra HD IP camera + video recording resolution in security exhibition, 4K ultra HD becomes next trend for HD video surveillance application. What's 4K? How does 4K technology use in video surveillance application? What's current problem for 4K ultra HD technology?

4K comes from earlier DCI (Digital Cinama Initiative), it's a defined digital cinema resolution DCI 4K (4096x2160 pixels, 24fps). Until 23 August 2012, ITU (International Telecom Union) released the ultra HDTV standard: ITU-R BT.2020, which is a landmark to UHD era. In reality, 4K and UHD are ultra high definition (UHD, or Ultra HD). ITU-R BT.2020 has defined the standard for ultra HD's resolution, fps, color range, UHD has 4K and 8K two phrases, 4K has 3840x2160 pixels resolution, total approximate 8.3 megapixel; while 8K has 7680x4320 pixels, approximate 33.20 megapixels. 4K support frame rate from 24fps to 120fps. In BT.2020 standard, has already cancelled interlaced scan, only contain progressive scan, which greatly improved the image quality. On color depth aspect, from BT.709 standard's 8bit increased to 10bit or 12bit. This improvement has play a key role to enhance the image's color depth and transition.

4K UHD IP Camera

comparing common resolutions in megapixels, and image size in pixels:

  • 4K = 8.3 megapixels, 3840x2160 pixels
  • 1080p = 2 megapixels, 1920x1080 pixels
  • 720p= 1 megapixel, 1280x720 pixels
  • D1 = 0.4 megapixel, 704x480 pixels

Currently, 4K is under rapid developing stage, 4K products become a hot topic, although there are many 4K products in the market, but mass production hasn't been achieved. Because the core component for 4K camera is still expensive including progressive image sensor and image signal processor. 4K's ultra high definition and large data also bring some problems including increased data storage space, high power consumption. Additionally, security manufacturers are still competing in low-end market, the demands for 4K ultra resolution are still low.Undoubtedly, 4K ultra HD is coming. Currently,CCTV-MALL Supply DAHUA 4K Ultra HD IP Camera.

4K ultra HD IP camera's main feature is its ultra high definition, and color image, hence utilizing ePTZ technology can provide wide video surveillance coverage. This can be useful in some outdoor surveillance places such as plaza, gymnasium, airport, bus station, beach...and more.

Furthermore, compared with 1080p full HD, 4K ultra HD can provide much higher resolution, this can provide users much more details from image/video footage. For example, ultra HD video streaming, facial recognition, plate license recognition and other smart video analysis result will be more accurate. The development and application of 4K will promote the entire video security industry toward high definition, meanwhile high definition brings new economic growth point to security manufacturers.


This higher level of detail in the picture afforded by a higher pixel count makes 4K security systems ideal for high-traffic areas where detail is crucial in indentifying the difference in someone dancing and fighting. Too often, lower resolution security cameras leave ambiguity lingering as to what really occurred in a surveillance video clip. 4K cameras clear up this ever so present uncertainty in video footage. Athletic fields, Schools, universities, big box retail, train/bus stations and government facilities are just a few of the industries that could benefit from these 4K security cameras.
