Short Description

Real-time voice translation across 49 languages. Dual-lane transcription shows both speakers simultaneously.

Long Description

DuoVox translates conversations in real time. It uses dual-lane technology to show both sides of a dialogue simultaneously — each language gets its own panel. With 43 languages on Professional, 33 on Standard and 30 offline, DuoVox works for travellers, professionals, and teams. Features include subtitle export, file translation, a translation glossary, and a Private Mode for sensitive conversations. In normal use the processing provider may retain limited operational logs; turning on Private Mode keeps those conversations out of those logs.

Short Description

Opens the CCTV footage no ordinary player will touch. Converts proprietary Chinese DVR recordings to standard MP4, on your own PC, for free.

Long Description

Most Chinese DVRs write footage in proprietary formats that VLC and Windows Media Player refuse to open. CCTV Converter identifies the format from each file's signature bytes — Xiongmai/HiSilicon .ps, Dahua .dav, Hikvision streams, raw H.264/H.265 and more than twenty extensions in all — and converts to MP4 in parallel for large batches, optionally burning a date and time clock into the video for evidence use. Version 2.1 adds automatic face redaction with area tracking, one-tap look presets with live gamma, motion detection inside a clip, a continuous whole-day timeline that plays a day of recordings as one video, and evidence reports carrying SHA-256 checksums for chain of custody. All processing runs on the user's own machine; footage is never uploaded.

Key Facts

• Pricing: free, with no accounts, no ads and no tracking
