Step-by-Step Guide to DVR Video Recovery Software

Step 1. Download the trial version of DVR Recovery™ from the DiskInternals website. After the software is downloaded, you can move on to installation. The recovery wizard will ask you to select a drive partition so it can scan for deleted files.

DVR Recovery™ doesn't change anything in your CCTV DVR system during the recovery process, so you can safely scan the entire volume.

Step 2. Connect drivers from the DVR recorder to the Windows 11, 10, 8.1, 8,7 or XP computer. To provide this connection, you need to take out the drivers and attach them as external storage devices.

DVR Recovery - select the disk.

You can also mount the image of a drive without actually connecting it, or create a new virtual partition by clicking on Map Virtual Partitions. For example, if you use NAS storage, you can attach it with the “Mount Wizard” option.

Step 3. Scanning. The software searches for videos and images in h264/h265 format and provides search by signatures, also known as Carving.

DVR Recovery™ shows the progress of the scanning. If you’re not good at waiting, you can make a nice big mug of tea or coffee and have a nice time. This is an automatic DVR data recovery process and here the CCTV DVR data recovery will begin.

Step 4. Preview. The search is done; you can preview all the restorable files in the Explorer-like window.

DVR Recovery - preview the video.

Just select the file (image or video) -> right-click and choose “Preview”. DiskInternals DVR HDD recovery software supports all the usual features of the Explorer, including file search, tree, and folder view; going backward and forward, and show file details. This CCTV footage recovery software will help you browse through all files easily and efficiently.

Step 4. Save the results. To recover files and folders, highlight them and click on the red cross "Recover" from the toolbar or the context menu. In the following window, select the destination and check the box to save the directory structure.

The trial version will allow you to check if the lost files can be recovered or not. To save found videos, you will need to purchase a license for DVR Recovery™ and enter the license key. The registration will allow high-quality export of CCTV data recovery and DVR recovery results.

If the right tool is applied, DVR data recovery becomes easy as one-two-three. The easy-to-follow wizard will put all the advantages of CCTV Camera Data Recovery software under your belt.

Why CCTV fails

Power-related issues

  1. 1. Energy supply line or supply voltage isn't always appropriate;
  1. 2. Electricity isn't sufficient (or there is an excessive amount of voltage attenuation on the cable);
  1. 3. Power supply machine transmission line brief circuit, open circuit, instant overvoltage and so on.

It must be stated that power supply error or instant overvoltage will cause device damage. Therefore, you need to test carefully before looking at energy-related causes.

Connection errors

As there are numerous cable connections at some stage in a surveillance system, flawed connections among primary equipment can be due to an open circuit, quick circuit, and poor line insulation.

In this example, there is a need to examine and troubleshoot to decide which line connection problems are to blame. Similarly, it should be noted that mechanical equipment needs to operate according to longtime running requirements.

CCTV hacker attacks

Cameras can also be hacked into. Often, unprotected cameras can be accessed through their IP address and disabled or moved. Unfortunately, this is a relatively simple process and anyone with the proper hacking experience can do this.

CCTV admin negligence

CCTV cameras can also fail due to administrator negligence. Sometimes, data can be accidentally deleted or hard drives can be overwritten if there are space constraints. That’s why it’s important to have CCTV camera data recovery software in these cases for DVR data recovery needs.

Hard drive failure

Sometimes, CCTVs don’t fail; it’s the hardware behind them that fails. In many cases, there is a hard drive failure, which either causes the video files to get deleted or corrupted. This case is very common and needs urgent DVR data recovery. With DiskInternals DVR hard disk data recovery software, you can get your files back.

Secure Data Recovery
