How often do you have to wait for a video image to load on your screen? You don’t have to accept this anymore. A breakthrough has been made to overcome bandwidth and storage challenges that the security and surveillance industry has been facing for years. The industry has entered a new era with the highly anticipated new generation of IP cameras that have inbuilt the state-of-the-art video image compression technology complying with the new H.265 international standard.
On September 12, 2014, Shenzhen ZNV Technology (ZNV) launched the world’s first H.265 high-definition IP camera (7200 series) at its 2014 Channel Partner Summit and New Product Launch Conference in Nanjing, China.
At the conference, Robert Zhu, executive chairman of ZNV, explained the technologies of this new IP camera series and the benefits for customers.
“All of us like to use high-definition cameras for security monitoring, remote machine operation, or other applications, because the sharp images will help us to identify security treats or control a machine remotely. The current challenges are the cost of transmission and storage of large-sized data over the network and cloud. The new IP cameras that we are launching today overcome these challenges by using the latest data compression technology inside the cameras. For the same high-definition videos, this technology can reduce the data size by three times in dynamic scenes like a busy street and up to 10 times in static scenes like a guarded warehouse,” he said.
Cost savings
“The benefits of this breakthrough are simple. For some high-definition videos, they will require much lower bandwidth and use much less storage. This will not only make a tremendous saving in system cost for our customers, but also make high-definition video possible in the areas that the existing network infrastructure simply can’t support,” Zhu added.
The team from ZNV demonstrated all the key features during the conference. The 400-plus audience were impressed by the new products and the first batch of products was all sold out at the conference.
The company predicts H.265 IP cameras will quickly be adopted by some retrofit projects where end-users expect to upgrade their video surveillance systems, such as the education sector. Other target customers are end-users that have demand for high-capacity storage devices, such as a smart city project.
“ZNV is focused on developing our own technologies around H.265 compression. We have been developing H.265 technology for two years and acquired many patents in decoding and encoding technologies, and system design. H.265 algorithm is more complex compared to H.264. It has to be flexible and accurate and follow many international standards.
An example is, we owned a patent in motion encoding technologies in order to largely reduce the bandwidth in the static scenes, which is useful for end-users who want to save the bandwidth and also cost of storage. A major issue of H.265 cameras is the overheating problem. We have solved this problem from the hardware design to the internal design for heat dissipation. We now are working on the application for this patent,” said Zhu.
The company further predicts that in a year, H.265 will be ready to grow in double digits.
Two success stories
ZNV used the new cameras in a smart city project in China. As part of this project, the police department requires that video must be stored for 12 months in order to check the recording history during police investigations. Due to the cost constraints, they only have limited storage space available which could only support 30 to 90 days video storage previously. As a result, earlier videos had to be deleted and overwritten, among which some important information was lost for criminal cases. With the H.265 technology, the police department can save up to 10 times of storage space, which translates into tens of millions in savings for the whole projects.
A school used a video surveillance system for years, but it gradually grew out-of-date and could not meet its increasing surveillance demands. This school wanted to use state-of-the-art high-definition cameras for video surveillance; however, normal high-definition cameras needed to be built on high bandwidth infrastructures, eg, a costly fibre network. Due to insufficient network bandwidth and financial pressure, the school had not found an optimal solution until recently. By taking advantage of the low-bandwidth requirement feature of ZNV’s 7200-series IP cameras, the school achieved a real-time, high-definition 1080p surveillance system under the existing network infrastructure. This saved tens of thousands of dollars and minimised the interruptions to school education programmes.
