How to recover the accidental deletion of surveillance video?

How to recover the accidental deletion of surveillance footage generally requires the help of data recovery software, as long as the data is not overwritten, it can be recovered.

How to recover the surveillance video after it is initialized and deleted? Now in the era of surveillance video everywhere, there are monitors everywhere you go. What should I do if the surveillance video is initialized and deleted by mistake? Use data recovery software to recover accidentally deleted **.

Next, select the disk you want to scan and select the disk where the surveillance footage is stored.

Click Next to select the data type you want to scan.

Click Next to enter the state of scanning data, try not to operate the computer while scanning, and wait patiently for the scan to end.

At the end of the scan, click on the monitoring**to preview, and the ** that can be previewed normally means that it can be recovered, and then select the one you want to recover**, click the recovery button below, and the surveillance video** can be successfully recovered.

files, USB flash drives, portable hard drives.

and other data.

Problem description: When DSS7016S2-D is used with a decoder, the client may encounter no decoding permission when the client runs on the wall, as shown in the following figure

Solution: 1. Ensure that the role corresponding to the user is configured with decoding channel permissions.

2. When organizing logically, you need to check the decoder and decoding channel at the same time, as shown in the following figure

Decoder 0612 has been added, but the decoding channel is not checked and added to the logical organization.

02 Function Module: Client - Preview.

Symptom: Error** or 13 in DSS Platform Preview

Solution: 1. There is no extranet

The platform uses multiple access mode and uses multiple NICs.

1. Ensure that in multiple access mode, each NIC is in a different network segment;

2. In the configuration system, add the extension address.

Second, there is an extranet situation:

1. The platform needs to be equipped with a fixed external network IP;

2. Whether the port mapping is successful, test the 9000 9100 9200 and 9320 ports through telnet.

For example: telnet 9100

If it shows that it is connecting or flashing, it means that it is not working, as shown in the following figure:

You can add mapped addresses in the configuration system.

Next, attach the computer to enable the telnet service method:

Step 1: In the start menu of your computer, find the Control Panel.

Step 2: Select "Programs";

Step 3: Select 'Turn Windows Features On/Off';

Step 4: Enable "Telnet Client" and click OK.

03 Functional module: client - electronic map.

Problem symptom: DSS7016-D is configured with an electronic map, and the login prompt on the client prompts "Sorry, your operation has timed out or the username and password are wrong, please log out of the client and log in again!" As shown below

04 Function module: Client - Video playback.

Problem symptom: When the DSS7016S2-D client plays back the video, when the device video is queried, there is a green bar on the timeline, click a certain point in time to play back the video, and the recording time always jumps forward or backward for several hours.

For example, if you play back a video at 12 o'clock, you will skip to 8 o'clock.

Solution: 1. Check whether the local playback of the video recorder is normal, verify whether the system time of the video recorder and camera is consistent with the current time, and verify whether the time zone is Greenwich Mean Time +8.

2. Check whether the current computer system time is consistent with the current time, and verify whether the time zone of the computer is Greenwich Mean Time +8.

3. Uninstall the client and reinstall it or try to change the computer.

05 Functional module: web terminal - device management.

Solution: Go to the NVR menu in order --- Security Center--- System Services ---Private Protocol Authentication Mode--- and select "Compatibility Mode". The interface diagram is as follows:

Although my creation in Toutiao was really bad, and there was no special attention from anyone, the income was even smaller, and I even wanted to give up at one point. But over and over again, I still feel that I should persevere, and if I still can't make a breakthrough after a while, then it's never too late for me to give up.

Of course, a large part of this kind of thing depends on luck. If I'm unlucky every time and can't catch the taste of the masses every time, then I'm really bad.

If I think about it carefully, I should start with the taste of the public, the current hot topic, and a more systematic topic. Now my focus is on health, and most of the audience is middle-aged and elderly.

I thought that this topic should be more attractive to everyone, but it didn't feel like it was as expected, as if the middle-aged and elderly people don't pay much attention to it now, and the young people don't pay much attention to it.

However, it may also be because the content I wrote is too boring, like a middle school essay, and there is no timely attraction point, so that everyone has no desire to read it as soon as they click on this article.

If it were me, I probably wouldn't like to read this kind of article either. I remember others said that people nowadays are ninety-nine-six every day, and they are physically and mentally exhausted, and when they come home from work, they click on their mobile phones just to watch some funny and interesting things and relax their body and mind.

If you open the health article, you may make your mood even heavier. I probably need to change my area of focus. Otherwise, I don't feel like a big breakthrough.

Today, I took a look at the income of yesterday's article, and it was only four cents, which is super super small, but the unit price of this article is higher than the previous articles. So although the snow reading volume of this article is not high, the final income is still good, at least a little higher than the previous penny.

I haven't conceived today's article yet.,I plan to continue to focus on health.,And then change it to something else.,There's already a topic I want to change.,I don't know if there's a new breakthrough.。

Although I also create ** in today's headlines, and almost every ** creation is two to three minutes, but it feels a bit long, because there are very few people who really see **the end.

But if you don't have a minute, the income will not be particularly high, so in the future, I can control the ** within one minute to two minutes, the best is one minute to one and a half minutes is better, of course, it doesn't have to be so strict, it's almost fine.

It takes me more effort to understand myself, and giving up is a very simple thing, so I can't just do simple things without trying hard.

If you can connect the monitored hard disk or memory to the computer, you can try, install 360 security guard on the computer, enter the function encyclopedia, find the file recovery tool, and scan the hard disk or memory.

After the monitoring route is deleted, if you want to restore it, you can only take it to the local data recovery center to try to recover, if it is deleted and overwritten by the new monitoring content, it is still difficult to recover.

In addition, you can also find a professional data recovery person or organization to help you recover the data, but the cost will be higher.

Hello, hello, dear customer, I'm here.

After the surveillance video is deleted, if you want to recover it, you can only go to some professional data recovery centers to try to scan and recover, and if they can scan it, you can also recover it.

If the video recording is particularly important, you should find a professional data recovery technician, and do not try to recover it yourself, otherwise it will increase the difficulty of the geometric multiple of the hard disk.

First of all, I can tell you clearly here that after the surveillance video is deleted, in fact, the content inside can still be recovered, but under normal circumstances, most people don't know how to recover, because the recovery procedure is still more troublesome, and the most important thing is that most people don't actually know this kind of technology, so most people think that as long as the content is deleted, there is no way to recover the content. First, what is the deletion mode? Under normal circumstances, the content in the hard disk, especially the surveillance video, in fact, there are several ways to delete, the first is the more common overwrite, because the surveillance video is continuous work, under normal circumstances, in order to ensure that it does not occupy too much content and space, so it will choose to delete and cover the new content at a certain time node, in this way, you can repeat the cycle, there is only one hard disk, but this also has a disadvantage, that is, it can only store the surveillance video for a certain period of time.

In addition to this mode, there are also human deletions and some hardware issues. Second, which deletion mode is best to recover? Among all the deletion modes, the easiest thing to be repaired is manual deletion, because under normal circumstances, there is no way to repeatedly operate the hard disk after manual deletion, that is to say, at this time, the format inside the hard disk has only changed once, and if you want to recover, you only need to follow specific rules to restore the magnetic inside the hard disk to the previous state.

In this case, it will be possible to read out some of the contents previously stored on the hard drive again, although there may be some flaws. Third, there is no way to solve the problem of hardware equipment. If the hardware equipment in the surveillance video is damaged, that is, it is physically damaged, there is no way to repair it, such as throwing it into a strong magnetic environment and being modified for a long time.

Or directly incinerate at high temperatures, which can directly destroy the disk.

Once deleted, it cannot be restored, and the deletion method is as follows:

Device: iPhone 12 ProMax

System: iOS

Software: Mi Home.

The first step is to click on the camera first, as shown in the figure below

Step 2: Click below to look back, as shown in the figure below:

Fourth, click on the icon at the top right, as shown in the figure below

Fifth, click OK on the pop-up page, as shown in the following figure:

It should be recoverable, if it is the monitoring content of the computer, in order to be able to understand the work status of employees, its data can be encrypted and protected by file encryption, such as using Domain Shield for screenshot audit and screen recording, if we delete the video stored on the computer by ourselves, these files will be automatically backed up, and the operation is carried out by the automatic backup of the document, and then we can restore the data through the automatic backup of the document.

First of all, it is possible to partially repair or restore the original data (**). After the video content is deleted, the disk still retains the corresponding data traces, and with the help of data repair software, a part of the content can be recovered, and the same is true for formatted disks.

On the whole, the repair is a certain probability, there is no 100% recovery, and there is a possibility that the repaired data is garbled.

After the surveillance video is generally deleted, it cannot be directly recovered, and it can be achieved with the help of third-party software, effective formatting and recovery effect, so we must pay attention to the proper preservation of relevant information when using it, so as to achieve a more ideal, safe and effective application effect.

After the CCTV footage is deleted. How can it be recovered? Monitor formatting. Roar. Can it still be recovered? I think. After the surveillance footage is deleted. Most of them can't be recovered. Monitoring format. It won't be restored after that.

If the surveillance footage is deleted, it can be recovered by technical means, but if it is formatted, then the file cannot be recovered.

As long as it is formatted in the video recorder, it is okay, if you remove the hard disk and perform a low-level format on the computer, there is no way to recover it. Restoring party....

"Ordinary people can't do recovery operations. It is difficult to recover the monitoring data is overwritten, and it is necessary to turn to scientific and technological professionals to rely on high-tech means to complete it, but the success rate of data recovery is small, and ordinary people cannot complete it. At present, the mastered monitoring data recovery technology is also effective for some of the data that is considered to have been covered, most of the information that is covered by the new content cycle can be recovered by the technology, in view of different situations, the amount of information that can be recovered is also different, according to the analysis, you can understand the information that exists after the monitoring is covered by the cycle, and estimate the success rate of data recovery.

can be recovered. However, there is no guarantee of 100% recovery. You can use Data Recovery Master, Lei Feng recovery software. easyrecover and other software;

If it is manually deleted**, there is still a high chance of recovery after the scan of the data recovery software, or it has just been overwritten for a long time**, you can also try to scan it with the software, but if it has been repeatedly overwritten several times, the recovery chance is naturally very slim.

To be clear, it is possible to recover if you don't have a new data overwrite, but this software is a paid software.
