Many new data recovery engineer may think it is very easy to recover deleted videos from HDDs or SD cards within the DVR/NVR/HVR/CCTV devices. Users may simply download some data recovery software to scan the lost deleted videos and recover them back, but this is not the truth!
Please note: DVR CCTV data recovery software is different from traditional data recovery software. The common file systems we see are FAT32, NTFS, exFAT, HFS+, EXT3, EXT4, etc but for DVR HDDs or SD cards, they have their own unique file systems and these file systems cannot be decoded by the common data recovery software and users must use special DVR CCTV data recovery software to access the DVR HDDs or SD cards.
For most DVR CCTV data recovery software in the market, they can just simply access to the DVR HDDs or SD cards and list the cameras and videos, but if the surveillance videos are deleted, these software cannot recover at all or the recovered videos cannot be played properly with blurred screens.
Dolphin DVR Pro. Business version offers two modes to access and recover lost deleted videos from DVR NVR HVR CCTV HDDs or SD cards: Fast mode by analyzing the index structure and contents and Deep mode for recovering deleted DVR videos.
So with Dolphin DVR Pro. Business version, it is easy for users to recover deleted videos at high speed.
