Because of project requirements, Dahua Video Surveillance needs to be moved to the web page. After searching a lot of information on the Internet, I finally found the plug-in package linked below. I debugged it myself, and it can run normally, and there are detailed secondary development materials in the package, which is very convenient. The test browser uses 360 Safe Browser, and it can be used normally in compatibility mode and speed mode.
Plug-in download: http://download.csdn.net/download/zhwzju/9447859

(The poster's literary talent is not good, please forgive me if the semantics are not smooth). Empty_Sky_xp children's boots in the Q&A area asked why the noright phenomenon occurs when the plug-in package is used to preview. Here are a few troubleshooting points.
1. Login error.
Solution: When you log in incorrectly, when you click on the real-time preview, there will be a noright problem. Therefore, please check the correctness of the account password, IP port and other information. But Empty_Sky_xp children's boots is not the problem
2. Version problem.
Solution: The version of the plug-in product in the development kit provided above is 3.1.0.233417, and the NVR remote terminal version used by the host is as shown in the screenshot below
The landlord debugged normally during the development process. But the NVR version of Empty_Sky_xp children's boots is different from mine, his is as follows
But the plug-in version he uses is the same as mine, but there will be noright problems. Later, in the continuous investigation of Empty_Sky_xp children's boots and I found that it turned out to be a problem with the plug-in version. Later, after Empty_Sky_xp children's boots updated the plug-in to the plug-in product version 3.1.0.341188, the noright problem was solved, and the function debugging was normal. Here is the download address of the plug-in version. Click to download the 3.1.0.341188 version of the plug-in .
Summary: Encountering this kind of plug-in version problem is the most pitiful. Just like the article by the host Haikang said, plug-in problems are the most difficult to troubleshoot. The ghost knows whether it is a problem with your own code or a problem with the hard drive. Hahaha, but in the end the problem is solved and I have accumulated experience for myself.

Due to update the download address above: replace the download address above
The version of the appeal, in fact, the landlord encountered a very serious problem, that is, he could not obtain the channel information of the hard disk drive, no matter how he tried, he could not obtain it. Later, I found a new version of the plug-in from a blogger and clicked to jump to the [Drunk Dream] blog . The plug-in provided by this blogger can normally call the interface for obtaining channel information, but although the host can call normally, the data returned by the interface is empty. After contacting the blogger later, the blogger said that he could do it there, and suspected that it was a problem with the configuration of the hard disk drive on my side (for details, please refer to the comments under the blogger’s article). Later, after trying N times, I gave up the investigation. So if you need to, you can click on the blog address given above.
