, you only need to log on to the video server over the network to view the monitoring images. Because of the TCP/IP architecture, the video server is very convenient to use. Any monitoring site only needs an IP address and can be configured with a fixed IP address to install the video server. A standard video server also requires RS232, rs422, or RS485 control interfaces and level input/output interfaces. The serial port can be used to conveniently implement remote control of cameras, cloud plat

I received several ZDI vulnerability bulletins that day, one of which is MS11-092. Due to the recent interest in file format vulnerabilities, PatchDiff2 compares the patch files. After comparison, the thief did not want to check whether there is a ready-made POC. GOOGLE has found some of hellok students in the snow hair "MS11-092 patch comparison analysis" this post. Oh! The enthusiasm of the brokers is so high that it is terrible! Hellok analyzed that this could be a heap overflow vulnerability

demand for a large amount of data, DVD forum in the Development of DVD-R specifications, take the following four points as the basis:1. DVD-R is a new type of record system with the same CD-R. 2. After recording the DVD-R optical disc, It is interchangeable with 100% of the general DVD dial-on. 3. Supports multi session recording 4. DVD-R optical discs have extremely high cost/performance values. DVD-R is led by pioneer company development can write a DVD specification, the earliest development

the Intranet DVR host; disadvantage is that the DVR host directly mapped to the Internet, the DVR is directly exposed to the public network, which is particularly vulnerable to attacks and viruses. 2. port ing: This method is relatively safe. Only valid ports are opened to effectively shield attacks from the Internet. Port 80 is required for remote monitoring th

-speed processing and storage of video stream information returned by multiple IP video front-end devices. The network monitoring terminal can be located in the same location as the network video recorder (such as the Network Monitoring Center), or remotely log on to the network video recorder through a secure network connection (such as VPN, implement remote monitoring management. Network video recorders can have a variety of different models based on different application and capacity requirem

The problem of data storage is very important, but in practical application it is wrong. Often appear out of disk, Volume lock Deng Many problems, seriously affecting the overall system of normal use, so the data dedicated storage has become the market's most concerned about security products. Traditional data storage mode In the current digital world, the most common is the following four types of storage: hard disk, DAS, NAS, SAN. 1. Hard Drive Whether the

A vro serves as the egress for communication between the entire network and the outside world and serves as a bridge connecting internal subnets. In the process of establishing a network, the purchase of a router is extremely important. Among all network devices, the price of routers is also very expensive, and it is the first scene of network equipment. Not like some Nic and hub functions and features 　　 Similar performance, and the price is basically the same, users do not have to worry about

packet, the middle through the N routes, The unicast packet enters the R1 smoothly; 2. When R1 detects that the packet port number is 9, the destination IP and port number of the packet is modified to 192.168.1.255:168 according to the port mapping entry, at which point the packet is R1 recognized as a directed broadcast packet because R1 has been set to allow subnet directed broadcasts, so the packet was not discarded; 3.R1 the broadcast packet to 4-port broadcast, S1,S2,S3,S4 all the ports

enterprise that set up a public server for external users to access. However, the popularization of information so that small and medium-sized enterprises may also set up different public servers to external users. For example, figure File Exchange, technical update information, report payment, etc. can be achieved by setting up a public server. To provide an open service, an enterprise must have a fixed address for Internet users to establish in the server address bar. The general approach is

higher the price. Therefore, you should make a targeted purchase, try to avoid idle functions that are purchased at a high price. Commonly used functions include packet filtering, including port filtering, IP address filtering, MAC address filtering, and keyword filtering. This allows you to flexibly set router analysis and determine whether incoming and outgoing packets pass or are rejected; A virtual server that allows Internet users to access WWW and FTP servers and other specific servers in

. The current Broadband Router has many rich functions, such as DDNS, NAT, and VPN. For some different users, these terms are just confusing. All the features of the Broadband Router must be clear before you can purchase them clearly. Otherwise, the purchased vro cannot meet the needs of the network, or the vro purchased at a high price has unnecessary high performance and functions. Therefore, it is enough to make the purchase. Of course, you need to

different IP users into different groups and name them. Through group management, all-round control functions can be achieved at one time. You can also avoid security vulnerabilities due to missing configurations. 3. Build an internal public server In the past, only a large enterprise may have set up a public server for external users to access. However, the popularization of information technology makes it possible for small and medium-sized enterprises to set up different public servers for e
