📡 How to recover a Video File from Non-Operational Video Recorder (Hikvision DS-7104NI-Q1/4P) 📡

00:53 - 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 in the street.

01:04 - 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.

01:13 - 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.

01:24 - Recorders keep their videos in a special format so extracting the data is not so easy as it seems.

01:30 - 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.

01:39 - 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.

01:46 - Why video recorders suffer from data loss Here are the most frequent reasons why information is lost: • Hardware and software failures of the video recorder; • Accidental or unintended deleting or damaging of video files; • Hard disk formatting or initialization; • Hard disk failures and so on.

02:03 - 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.

02:11 - What if the video recorder broke down? 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.

02:20 - 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.

02:29 - 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.

02:36 - But what if you don’t have such software? Try finding another video recorder of the same model - or use a data recovery tool.

02:44 - Video recorder specifications This recorder model supports third-party cameras as well and lets you connect as many as four IP cameras.

02:53 - An effective video compression system helps the device to use less space for storing videos.

03:01 - In the back panel, there are two video output channels – HDMI and VGA, a 100 Mbit Ethernet port, two USB ports, and 4 independent Power over Ethernet (PoE), and of course, a power connector.

03:16 - Inside, there is a slot for one hard disk and a connector supporting disks up to 6 TB.

03:23 - Backup settings If you need to recover an old video, you should remember that any video recorder has to work with a limited memory capacity.

03:32 - 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 older data with new files.

03:42 - If a new record cycle has already begun, it’s unlikely that older videos can be recovered.

03:48 - In general, before doing anything to the information which you think is important - formatting, deleting, partitioning and so on - always remember to back up your stuff.

03:58 - Most recorder models let you configure the backup process, so you can manage the schedule, select cameras, video type and many other things.

04:05 - If there are no video backup files, then use Hetman Partition Recovery, an effective data recovery tool.

04:12 - How to recover data with Hetman Partition Recovery To recover data from the hard disk of a video recorder, connect the disk to a Windows computer.

04:19 - Take out 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.

04:30 - 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.

04:41 - 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.

04:52 - Run Hetman Partition Recovery. The program can recognize the disk, and it detect its file system as hikvision.

05:14 - Right-click on the disk and open it. Select Fast scan and wait.

05:22 - If the Fast scan result is unsatisfactory, try a deeper scan instead.

05:50 - As you can see, the program managed to find the remaining data easily.

05:55 - As a rule, video recorder files have similar names of the same type.

05:59 - If you need to recover a certain video you can find it by using the preview function.

06:27 - Select the files you need to extract from the disk and click “Recovery,” specify where to save the data and click “Recovery” again.

06:46 - When the process is over, you will find the recovered files in the folder you have chosen for saving them.

07:02 - Also, there are video recorders with RAID support that give you ample opportunities to secure your data.

07:13 - If you need to recover information from this kind of recorder, use Hetman RAID Recovery.

07:18 - It will identify its properties automatically and rebuild the damaged RAID system, so that you can copy the important data to a safer location.
