Unequaled data recovery form CCTV units
The program allows achieving outstanding results of video recovery from most surveillance devices that may employ general-purpose file systems, like XFS, EXT, FAT32, or vendor-specific types, like WFS, DHFS, HIK, Mirage, Pinetron, BKFL, etc. Also, the software works with various stream and video compression formats that are usually not supported by regular data recovery utilities.
Maximum recovered output from driving recorders
The software enables highly efficient recovery of footages from numerous vehicle DVRs, including the latest models. Even in cases when the video was partially overwritten or the process of its recording was interrupted due to an accident, it is still possible to obtain an intact video file thanks to a mechanism that uses "tails" or "holes" of previously allocated files and a special video transmuxing technique.

Key features

Smart scanning procedure Smart scanning procedure
The software automatically recognizes the supported CCTV/EDR formats (file system, video stream, video/audio codecs, vendor-specific metadata, etc.) and restores the lost recordings without the need for any special configurations. No prior analysis of the data is required – all the necessary algorithms are already embedded into the program.
Extensive toolset covering almost any data loss challenge Extensive toolset covering almost any data loss challenge
The application offers an exceedingly broad functionality which mostly overlaps with the one available in the Professional edition of UFS Explorer. It contains tools for work with different storage technologies, complex RAID-based devices, encrypted volumes, virtual disks of popular virtual machines, disks with non-standard sector sizes, defective drives and enables efficient analysis of raw binary data and its convenient editing.
Support of forensic disk images Support of forensic disk images
Aside from conventional disk images, UFS Explorer Video Recovery is capable of processing ones created with professional forensic tools – EnCase Imager and FTK Disk Imager. The utility allows opening and exploring the content of a forensic disk image created for a particular drive, volume or file and makes it possible to scan it for lost data like any ordinary physical storage device.
Special technique for video transmuxing Special technique for video transmuxing
The obtained footages can be repacked by the software into the universal file format supported by most standard media players. In contrast to transcoding, no changes are made to the actual video or audio content – the original data and codecs remain fully preserved which is of critical importance for the tasks related to the retrieval of digital evidence in the context of forensics and cyber security.
Analysis of the video data Analysis of the video data
The program is able to analyze the allocation of video data on the disk and can provide a report on the location of frames the video consists of. Moreover, it allows establishing control over the content of files by calculating their checksums – a change of at least one byte can be easily spotted due to the difference of the file’s checksums in several reports.
Advanced methods of data reconstruction Advanced methods of data reconstruction
The application is able to reconstruct damaged file systems and recover lost data even in cases of serious storage corruption. When a logical issue leads to the loss of information about the allocation of fragmented files, the program is capable of restoring footages through finding and matching their segments, providing a fully functional video file as a recovery result.
Multiple scanning options Multiple scanning options
Along with the direct access to the available content, the utility offers several possibilities of the search for deleted and lost information: a scan for CCTV video data with a set of optional filters, recovery of RIFF/QTFF videos recorded EDR systems and a traditional configurable scan to recover files of all types.
Useful supplementary features Useful supplementary features
The program makes it easy to restore footages recorded on a particular date or by a certain surveillance camera. All recovered videos can be sorted by diverse criteria and previewed directly in the software. Moreover, the software allows extracting each video frame from the recording and converting them into a series of still images. Also, the obtained scan result can be effortlessly saved for further references.
