surveillance systems were called CCTV, the closed-circuit television monitoring system, which was the first generation. The equipment mainly consisted of analog cameras, video splitters, video cables, matrices, keyboards, and video equipment VCR. The CCTV system has nothing to do with computers and networks. Even if the computer can be used for GUI operations and the matrix networking function is added later, the core technology is analog switching. The emergence of the second generation of DVR

1. Get the R value and the P value between the dataset:R_fta_pts,p_value = Pearsonr (nba_stats["pts"],nba_stats["FTA"])R_stl_pf,p_value = Pearsonr (nba_stats["STL"],nba_stats["PF"]) # It'll return R value and P value.2. The function of getting convariance form the data set, the Convariance is the value of this measure how much both variables correlated with all other. If one changes to bigger, the other changes to bigger. Which said these, variables i

It should be said that the current routing technology is very mature, and there are also a variety of routing, evdo router is one of them. I am not very familiar with the evdo router. After reading the next article, I learned that the evdo router can do this. The arrival of 3G poses a challenge to many technologies. So, let's catch up. We can use limited network resources to make wireless business. System Background: With the official issuance of 3G licenses, the 3G war between operators will al

The Linux Shell (ShellShock) vulnerability is causing a global information security crisis. hackers have developed a worm that automatically spreads through the shell (ShellShock) vulnerability. According to an analysis from Kingsoft drug overlord's Security Center, the main purpose of the worm virus is to intrude a DVR (hard drive video recorder) device in China, hackers use these devices to dig for litecoin (a digital currency similar to Bitcoin), a

learned some long-term lessons: 1. When the pointer is used as a parameter, the ref or out keyword must be used in C #, especially the struct pointer. It is not appropriate to report memory read errors even if no error data is reported.

EPG is an indispensable software for PVR/DVR. It provides programs to users in advance, and users place orders through reservation ", PVR/DVRs Enable Automatic Recording of programs based on the user's reservation. At present,

1. If you have more than one screen of data, you can use keywords to find the relevant records and then locate them. The procedure is as follows: Traverse all rows, compare the values of a cell with the keywords, clear all selected rows, and set the current row as the selection, then, set the currentcell of the grid to a visible cell of the current row, and the result will automatically jump to the located row. Example Code : String Inputstr = Txtfindsp. text; Foreach (Datagridviewro

Route reallocation-long journey The solutions listed above have actually taken time from failure to recovery. In simple application scenarios, restoring a certain number of routes to a new node is not slow. But imagine that if there are thousands of routes, it will take several hours to complete the re-allocation and configuration process. People need fast fault recovery! Distributed Virtual Rout
