DVR-F40 is industry's very first DVR specially designed for the interrogation/interview process of all law enforcement agencies. Taking advantadge of the latest H.264E video compression technology, DVR-F40 can record long hours (days) of interviewing process (synchronized video and audio) onto the high capacity SATA harddrives with the easy one touch start/stop operation. Case Number, titles or other text info can be added and overlayed onto the video. Video/Audio files are backuped directly to CD/DVD disks while recording to the harddrive, thus no more additional waiting for takeaway backups. Combo Unit: Built-in high resolution 5" LCD and replay of backup CD/DVD using the built-in twin DVD players make it portable to be carried into the fields. Easy Operation: single key to start/stop, pause/resume recording. Direct backup of video/audio recordings to CD/DVDs - the CD/DVD backups are ready to be marked and filed away as soon as the interrogation ends, no more additional backup procedures and the long waiting. Text Overlay: allows special information (such as Case #, File #, interviewee name, date, time, or location) to be overlayed on to the video recording for identification or/and video protection. Picture-in-Picture: allows for PIP viewing and recording. Dual DVD Burners: double backup CD/DVDs can be generated simultaneously. Two burners can also be setup in circular mode to support hot CD-swappable. Two Way Audio: Microphone and intercom interface. Watermark Technology: proprietary watermark technology prevents video data modification.
