 Hello everybody! In today's video, I'm going to show you how to recover data from the hard disk of a network video recorder hack vision the S7-1104. In our channel and blog, you will find solutions to any problem, from installing an operating system or configuring it, to fixing possible bugs and errors or optimizing mobile gadgets. Our specialists will answer any questions you ask in your comments under the videos or articles. These days, video surveillance systems are becoming a standard not only for offices and shops, but also for home-based systems when people want to have more control over what's happening inside their apartment or industry. While previously such systems were based on computers, now the most popular choice are autonomous DVR systems, which don't need any PC at all. Errors, failures or accidental removal of a video from the hard disk of the video recorder may become a very painful experience if that specific video file was very important. Recorders keep their videos in a special format, so extracting the data is not so easy, as it seems. You will need specialized software provided by the device manufacturer and if the file is deleted, a special program capable of finding the lost data and displaying it. Let's start by analyzing the reasons causing data loss for video recorders and then find out how to recover data from a hard disk. Here are the most frequent reasons why information is lost. Hardware and software failures of the video recorder Accidental or unintended deleting or damaging video files Hard disk formatting or initialization Hard disk failures and so on. If your hard disk failed, it is hardly possible to restore the lost information on your own, so it's better to contact a company specializing in data recovery. If the video recorder breaks down, there is nothing to be recovered because all the data is still there, on the hard disk inside the device. However, if you connect the disk to the computer, don't expect to see anything. What is more, the disk management will suggest initializing it. For cases like this, what you need is a special software tool provided by the recorder manufacturer, which can help you see the video files. But what if you don't have such software? Try finding another video recorder of the same model, or use a data recovery tool. This recorder model supports third-party cameras as well, and lets you connect as many as four IP cameras. An effective video compression system helps the device to use less space for storing videos. In the back panel, there are two video output channels – HDMI and VGA, a 100-megabit Ethernet port, two USB ports and four independent power-over-ethernet connectors, and of course a power connector. Inside, there is a slot for one hard disk and a connector supporting disks up to 6-terabyte. If you need to recover an old video, you should remember that any video recorder has to work with a limited memory capacity. Depending on the quality of the picture and the number of cameras, it can record video files for a certain period of time, and then it will overwrite all the data with new files. If a new record cycle has already begun, it's unlikely that all the videos can be recovered. In general, before doing anything to the information which you think is important – formatting, deleting, partitioning, and so on – always remember to backup your stuff. Most recorder models let you configure the backup process so you can manage the schedule, select cameras, videotype, and many other things. If there are no video backup files, then use Hetman Partition Recovery – an effective data recovery tool. To recover data from the hard disk of a video recorder, connect the disk to a Windows computer. Take all the screws and open the cover of the recorder, take out the hard disk, disconnect it from the recorder, and connect the disk to the computer. When connected, the disk is not displayed in the Windows Explorer, and the operating system suggests to initialize it. But it's not necessary now, so just hit cancel. As we know, initialization will erase all the data which is still on the disk, and any recovery operations you conduct later can hardly be successful. Run Hetman Partition Recovery. The program can recognize the disk and it detects its file system as HicVision. Right-click on the disk and open it. Select Fast Scan and wait. If the fast scan result is unsatisfactory, try a deeper scan instead. As you can see, the program managed to find the remaining data easily. As a rule, video recorder files have similar names of the same type. If you need to recover a certain video, you can find it by using the Preview function. Select the files you need to extract from the disk and click Recovery. Specify where to save the data and click Recovery again. When the process is over, you will find the recovered files in the folder you have chosen for saving them. Also, there are video recorders with rate support that give you ample opportunities to secure your data. If you need to recover information from this kind of recorder, use Hetman Rate Recovery. It will identify its properties automatically and rebuild the damaged rate system so that you can copy the important data to a safer location. That is all for now. Hopefully, this video was useful.
