Where Are CCTV/DVR Videos Stored?
Depending on the camera model, there are different methods for storing CCTV footage. Some models utilize hard disk drives or solid-state drives that continuously record throughout the day. Others come with built-in storage that can be expanded by adding SD cards to accommodate more recordings.
Many modern models also offer cloud storage options that save surveillance files online. Lastly, there are external devices such as digital video recorders (DVRs) and network video recorders (NVRs) that store the footage from CCTV cameras.
Worth Noting: CCTV May Delete Videos Automatically Under Several Factors
CCTV footage saved on physical storage devices such as HDDs, SSDs, and memory cards typically does not get deleted automatically. However, as these storage devices have a limited capacity, they will eventually fill up. Once they reach this limit, older footage will start to be replaced by newer recordings.
Several factors can influence the speed at which footage is overwritten:
- The capacity of the storage device: When it hits its maximum limit, your security cameras will begin to overwrite the older recordings with new ones.
- The number of CCTV cameras in your system: Each camera in your surveillance setup requires storage for its footage. Therefore, having more cameras will increase the required storage space, leading to more frequent overwriting if storage is limited.
- The resolution of the security cameras you have installed: CCTV cameras with higher resolutions generate larger video files, which can consume storage space more quickly and result in shorter retention of footage.
Why Are the DVR/CCTV Videos Lost?
There are a variety of situations that can lead to the loss of CCTV/DVR footage, including:
- Unintentional deletion of recordings.
- Failure of the hard drive firmware.
- Insufficient storage.
- Corruption or formatting of the disk.
- Loss of power.
- Mechanical failure of the recorder’s hard drive.
- Problems with the recorder hardware.
- Software errors.
- File system errors.
Is It Possible to Recover CCTV or DVR Footage?
Definitely! It is possible to recover deleted videos from CCTV, but there are specific criteria that must be met.
- You should utilize a robust and professional data recovery tool capable of retrieving deleted CCTV footage, like MiniTool Photo Recovery or MiniTool Power Data Recovery.
- Ensure that the footage hasn’t been overwritten multiple times, as that complicates the recovery process.
Problem: What if Windows Cannot Read the CCTV/DVR Hard Drive?
“How can I make my DVR HDD readable in a Windows 10 PC? It asks to reinitialize the HDD when I connect to the PC. I do not want to reinitialize the HDD and lose all the data on it. Any help would be appreciated.”quora.com
Some of you may encounter the problem that Windows cannot read your hard drive once you connect it to your PC and asks to format it. Moreover, the disk is not displayed in Windows Explorer or Disk Management.
In this situation, you need to click the Cancel button to deny formatting your hard drive. As we all know, formatting will delete all the files stored on the disk and make the CCCTV or DVR video recovery more difficult.
To access your DVR/CCTV HDD on a Windows 10 PC without formatting, you might consider the following steps. However, it’s important to remember that DVRs frequently utilize proprietary file systems that Windows may not support. Here are some approaches you can try:
Solution 1. Verify File System Compatibility
DVRs generally operate using file systems such as EXT3, EXT4, or proprietary formats. Windows doesn’t support these file systems out of the box. To read the HDD without wiping it, you will require third-party applications, like Linux Live USB, DiskInternals Linux Reader, or Explore2fs.
Solution 2. Use Data Recovery Applications
If the above options fail to assist you in accessing your data, you might want to consider data recovery software compatible with your CCTV/DVR’s file system. MiniTool Power Data Recovery can be your best choice.
Solution 3. Transfer Data to Another Drive
If you have a second DVR or another compatible device, you could reconnect the HDD to the original DVR and transfer recordings to another storage device (such as an external HDD) that can then be linked to your PC.
Key Considerations
- Avoid Reformatting: Do not opt to reformat the HDD if prompted by Windows, as this will delete all data.
- Back Up Your Data: After gaining access to your data, consider backing it up to avert potential future losses.

Step 3. Double-click each video to preview it for confirmation. Afterwards, click the Save button in the lower right corner. Then you will be asked to select a directory to store the recovered files. Select one separate from the original location to avoid data overwriting, and click OK.

Case 2. Recover Lost Videos from CCTV/DVR’s SD Card
Step 1. Connect your SD card to the PC with a card reader. Open MiniTool Power Data Recovery to enter its main interface. In the Logical Drives section, your SD card will be marked with a USB icon. Select your SD card’s partition and click Scan.

Step 2. Once the scan is completed, you can start finding the pictures you want to recover. The MiniTool data recovery software offers two file view methods: Path and Type.
- Under Path, expand folders to view your files according to the original folder structure.
- Under Type, browse your files based on file type and format. To recover videos, you can navigate to All File Types > Audio & Video.

Moreover, the Search feature can also help you find your files faster. Input keywords of your file name in the search box and press Enter to search for it.
Once you find a target file, double-click it to preview its content.
Step 3. Make sure all the files you want to recover are checked. Then, click the Save button in the lower right corner. In the new window, select a safe location and click OK to save them.
