H.265 4K NVR (Network Video Recorder) Knowledge Introduction

Since 2015, many famous China network video recorder manufacturers have released their H.265 4K NVR(Video Network Recorder), that indicates  surveillance market will enter H.265 4K extra high definition new generation.

What is H.265 and its benefits

H.265 is a new generation of video coding standard that can transmit higher quality video in limited bandwidth network, only half of the original bandwidth, you can play the same quality video.
H.265 standard around the existing video coding standard H.264, some retain the original technology, but to improve on a number of related technologies. The new technology uses advanced technology to improve relations stream, encoding quality, and delay between algorithm complexity, optimize settings.

In the same resolution, H.265 standard only need the half  of  H.264 bandwidth. At the same picture quality as compared to H.264, H.265 encoded video by reducing the size of approximately 39-44%. Due to the different measurement methods of quality control, this data will be a corresponding change. Obtained by subjective visual test data show that the rate reduction in 51-74% of cases, the quality of video coding H.265 to H.264 encoded video also similar or even better. H.265 will analyze whether there is movement in each frame of the picture, then there is no change in the partially compressed. If the frame is still more higher the compression ratio, since most videos are part of 90% does not change, so that the compression efficiency of the compression ensures increased without lowering the picture quality.

What is 4K resolution?
4K resolution is  4096 × 2160 pixel resolution, which is four times the resolution of 1080P high-definition , are ultra-HD resolution. In the monitoring system, if amazing 4096 × 2160 pixels, the user can see the monitor screen in every detail.
In the field of digital technology, usually binary, but with the pixels of the image to describe the size of the digital image. Due to the large number of pixels constituting a digital image, K is usually expressed. 2 of 10 power of 1024, therefore: 1K = 2 ^ 10 = 1024,2K = 2 ^ 11 = 2048,4K = 2 ^ 12 = 4096.

In the digital cinema applications, typically 2K image by 2048 × 1080 pixels constituted, wherein 2048 indicates the number of pixels in the horizontal direction, 1080 indicates the number of pixels in the vertical direction; 4K image is 4096 × 2160 pixels constituted, wherein 4096 represents the number of pixels in the horizontal direction, 2160 represents the number of pixels in the vertical direction.

What are the benefits of 4K resolution?

With the development of image processing technology and image clarity people have become increasingly demanding, video surveillance systems increasingly high resolution. From the traditional standard definition resolution, to the network after megapixels, millions of pixels are now moving in the direction of development. 4K resolution can provide bigger monitoring range and more details,  to help solve the case, the accuracy rate of intelligence analysis.
4K cameras can provide greater monitoring range, a 4K camera can replace several conventional SD cameras, it is possible to reduce the number of surveillance cameras, reducing the monitoring system

H.265 and 4K relationship
With the improvement of the resolution, the amount of image data is also growing, if it continues to use the traditional method of video compression, will bring huge challenges of network bandwidth and data storage, can provide more than H.264 and H.265 high nearly double the compression ratio, under the same image quality, only half of the bandwidth, H.265 is ideal for ultra-high resolution video transmission and storage.


Which Chinese suppliers can provide H.265 4K NVR?
Currently, only a few of China DVR / NVR manufacturers can offer H.265 4K network video recorder, For example Hikvision, Dahua, Sysvideo.

Sysvideo Released 2016 New Catalog & Price List, Launched H.265 IP Camera & H.265 4K NVR

Jan 10, 2016, in Shenzhen, China. As the China's leading professional HD IP cameras and NVR/DVR manufacturer, developer in China, Sysvideo released 2016 new version catalog and price list, it launched a lot of new products:
1. SC6000 professional series: Launched  H.265 4MP/3MP 25fps real time cameras, 4 megapixel 25fps cameras market is rapid growth;

2. SC5000 low cost series: Launched  Sony IMX238 sensor 1.4MP (1280*1024) low light series cameras, H.265 full series 3MP/4MP/5MP products, although the price is higher, but the quality is  beter much;

3. SN7000 series NVR: Launched  16 ports PoE 16ch/32ch NVR, launched AHD,TVI DVR and  hybrid DVR, stop some old models, reduce some model prices, customer can update current analog CCTV system to HD with low cost.

4. Enterprise NVR series: Launched H.265 4K NVR RAID product line, H.265 & 4K is  hot topic now, it  will is the trend on the future. H.265 can save around 50% bandwidth and storage space. SN-S intelligent NVR series added RAID5 function (software RAID, don't add cost). New H.265 NVR can support 4K/8MP/5MP/4MP/3MP/1080P H.265/H.264 IP cameras, support 4K resolution output, it will greatly improve picture quality.

5. Added others some new products: 1080P HD mobile NVR, laser PTZ IP camera, all-in-one mini PTZ IR bullet IP cameras.

we think H.265 products will be popular in 2016, global IP surveillance will keep the fast growth, although AHD is hot in 2015, but it only can provide 720P and 1080P resolution, it is only suitable home & small business low end market. IP still is security system mainstream.
In addition, the total solution is  very important for IP system, we will not only produce single products, we will also continue to improve the product line and provide  a variety of solutions according to the customer's project requirement. We hope the customers can find all HD surveillance solutions from Sysvideo!
