The development of smart things has become commonplace, and smart hardware in daily life is everywhere. From smart TVs to smart wearable devices, smart hardware seems to have been with people's lives. As the most commonly used intelligent hardware devices in the home, smart cameras are beginning to enter the homes of ordinary people. The smart camera transforms from a simple monitoring role to a home-grown housekeeping expert. However, for people who are already using or wanting to buy smart cameras, the same problem often exists in the market for a wide range of smart camera products, that is, blurred image quality.
The main function point of a smart camera is to be able to "see" everything! Recently, in order to provide users with a high-definition picture quality, optimize their user experience. Lenovo introduced a brand new brand: Lenovo's Lecoo, and released three new products, one of which is a smart home video camera equipped with H.265 video encoding technology - Lenovo's Lecoo Watchdog (hereinafter referred to as the Homebest), as a Lenovo smart object One of the first batch of empowerment products, the Watchdog can effectively solve some problems in the use of the user.
So, let me briefly introduce the H.265 video coding technology. H.265 full-rate video coding (HEVC) is a video compression standard and is considered as ITU-T H.264/. The successor to the MPEG-4 AVC standard. HEVC can not only improve the video quality, but also can achieve H.264/MPEG-4 AVC twice the compression rate (equivalent to the same picture quality, the bit rate is reduced to 50%), can support 4K resolution and even to Ultra HD TV (UHDTV), the highest resolution can reach 8192×4320 (8 K resolution). In terms of popular terms, H.265 is a new video compression standard. The core value is to transmit higher quality network video under limited bandwidth. Only about half of the original bandwidth is required to play video of the same quality. This means that users can enjoy higher quality audio and video services at the same bandwidth cost.
From the video application perspective, H.265 application technology has two main advantages. First: High-definition quality. With the same transmission speed of the network speed, the picture with the same volume of video files and equipped with H.265 technology has higher definition. If equipped with ordinary technology, if users need to remotely watch a 3 megapixel high-definition picture, 6M uplink network bandwidth is required, which means that 4M network remote can not see 3 million HD effects. And equipped with new H.265 technology, 4M bandwidth can see a 3 million high-definition picture, 2 2 million high-definition picture, 10M bandwidth, can see 3 3 million high-definition picture, 5 2 million high-definition picture! Explain that, supposing that H.265 technology is installed on a smart camera and uses the same volume of stored files, users will experience a video quality experience with a high color code rate and a high frame rate. Not only will each frame be clearly visible. In front of eyes, the color will also be greatly improved.
Second: low storage. With the same transmission speed of the network speed, the video files with the same definition and the storage capacity of the H.265 technology are smaller. Assume that the storage capacity of a 2 megapixel ordinary camera is 40 Gigabytes per day. Then, the 2 million cameras equipped with H.265 technology have a storage capacity of only 20 Gigabytes per day! Users can greatly save equipment costs and achieve efficient storage.
