Video Surveillance Linux

Video surveillance as an important basis for verification, in the banking, judicial, safe City application is very wide, and with the development of technology and the needs of the times, many places are installed high-definition cameras. The data in these places need to be stored for 1-3 months or even more than half a year. 　　The advent of the era of high-definition, not only requires the High-definition camera, its storage screen also has the requirements of HD, which is the storage technology has put forward a great challenge. HD Monitoring storage Requirements According to the modern security monitoring of storage requirements can be summed up as a simple "five high": ...

The NSA's "massive surveillance" data center in the Utah State Desert can screen and analyze most of the world's network traffic, from geographical locations, audio and video files, e-mail, instant messaging, social networks and other digital documents. Of course, it's not just the NSA that can track our digital footprint, but in this time of personal privacy, all kinds of government and business companies can master our words and every move. 　　As a common netizen, is there a reliable way to protect themselves? Earlier, the Washington Post had given five individuals to avoid NSA surveillance ...

We've all been talking about cloud computing, but there's always a question: what exactly is the cloud domain, and isn't it changing now? Many cloud computing systems are becoming more sophisticated, but not dramatically improved, and that is often a good thing. But there are indeed innovations in cloud computing, and many innovative technologies (including the 6 technologies discussed below) are likely to affect your business this year. Gene sequencing currently, the use of powerful supercomputers to help cancer research is not new, ...

Cloud storage is a completely new concept that extends from the concept of cloud computing. It refers to a large number of different types of storage in the network through functions such as cluster application, grid technology or distributed file system Equipment through the application of software together to work together to provide external data storage and business access functions of a system. When the core of cloud computing system computing and processing is the storage and management of a large amount of data, a large amount of storage devices need to be configured in the cloud computing system, and then the cloud computing system is transformed into a cloud storage system.

Cloud computing Concept Cloud is actually a metaphor for the network, the Internet. In the past, the cloud was used to represent the telecommunications network, which was later used to represent the abstraction of the Internet and underlying infrastructure. Cloud computing is divided into narrow cloud computing and broad cloud computing. Narrow cloud computing refers to the delivery and usage patterns of IT infrastructure, which means acquiring the required resources through the network on an as-needed and extensible basis; broad cloud computing refers to the delivery and usage patterns of services, which means that the required services are obtained through the network in an on-demand, extensible manner. If only the next definition, people still can't understand what is cloud computing, we give a very simple example ...

Chinese hackers designed the world's first source of hardware Open-source notebooks Xinguo, an American-renowned Chinese hardware hacker (Andrew Huang, nicknamed Bunnie), partnered with people to create a laptop computer using open source hardware. All parameters of the notebook's main hardware are public. You might ask, is hardware necessary to open source? Do you really think your laptop is safe in a time when surveillance is ubiquitous in the U.S. National Security Service and other agencies or organizations? Is every part of it safe and airtight? At first blush, these questions seem to be a bit of a delusion of persecution ...
