preview to reduce the code rate, and do not affect the local video proposed dual-stream technology, that is, one video into the DVR, DVR can encode to provide two kinds of code stream, main stream and sub- The main stream resolution is higher than the sub-code stream, the main stream is used for video recording, the sub-stream is used for network transmission, the default client access using the main code

Black more than 70 surveillance cameras are so simple Recently, a security researcher found that surveillance cameras sold by more than 70 vendors are vulnerable to Remote Code Execution (RCE) attacks. According to the Rotem Kemer study by security researcher, surveillance cameras sold by more than 70 vendors are vulnerable to Remote Code Execution (RCE) attacks. The researchers noted that the products being sold by the supplier use the same firmware that is vulnerable to RCE attacks. In the "

First, the actual use of peanut rods wiring method:1. Connect the peanut wand and the router's LAN port with a network cable first2. Power the peanut wand with an external USB power supplyPeanut Rod-USB power supply (optional):Peanut sticks do not have their own power supply, but we picked out the quality of the better USB power.Note: Be sure to use a stable external USB power supply to ensure proper use of the peanut stickSecond, peanut stick set use method:1.

The DVR is configured with a m clock speed of arm11 and M memory, half of which are allocated to the video decoder. The kernel and other processes also occupy a lot of memory, leaving less memory for Qt to run. Later, we transplanted QT browser and QT WebKit to the DVR for map display. Although some functions have been cropped out, the running is still very card, and the QT interface process is easy to ente

These days, we have been working on dynamic library testing. H has written a written dynamic library-the library of the preprocessing module. The video processing project must be connected to the actual situation for testing. Requirements: 1. Connect the actual camera, read the real-time data stream, and save it to the dual-loop linked list; 2. Test the functional effects of Background Modeling; 3. Pre-processing the four data (image) display results; 4. Test the real-time processing of mul

, such as Sif, CIF, 4cif, and D1, are often used in video capture cards, compression cards, and DVR products. In fact, due to the lack of industry standards and standards in the security industry, many terms in the industry come from standards in other industries. Therefore, CIF, Sif, D1, and other words are not only from different sources, even nouns have been confused and confused. If we look back at the source, the video surveillance industry for s

, expansion, and disaster recovery are implemented.At the beginning of the network and digital era, different storage solutions were adopted based on the project scale. For example, in small-scale video surveillance systems, low-cost DVR storage has become the mainstream, while SAN storage is the mainstream in multi-level networking centralized video surveillance systems. These two solutions solve the digitization problem and overcome the disadvantage

China since the 1980s S. With the rapid increase in security demand, it has been developing rapidly. At the technical level, it has gone through the following stages of development. The first generation of fully simulated monitoring, also called closed-circuit television monitoring, has dominated the security market for more than a decade from the 1980s s to the 90 s, and a large number of applications in public security, banking, military, transportation, hotels and other important units and d
