Viperfish Nitro

Designed for top-side applications, the Viperfish Nitro is a high performance shock and vibration proof digital recorder that converts analog video to digital format. It records high resolution video (720×486), full speed 30 frames per second. The high performance digital platform, Optophore 1 combines a 1GHz processor board with wavelet compression. Wavelet compression searches the entire field or each frame at once resulting in no blocking of artifacts. The result is clear, crisp, non-jerky and non-multiplexed video.

Reliability and Clarity

The new Optophore 1 digital platform combines Linux real time operating system with a wavelet compression resulting in clear non-fuzzy video. That’s because unlike other compression schemes Wavelet performs a detailed mathematical analysis of the entire field or each frame at once – unlike MPEG which only records the changes in each field. The performance comparison between Wavelet and MPEG compression is most noticeable when there is motion detected – which is over 98% of the time in all applications.

Features such as adjustable frame rate and adjustable picture quality allow you to choose the quality of the image you wish to record. You can record and view video simultaneously. Overlay audio on disk to record important thoughts you have at critical times during your project. The Alarm Verification feature allows you to mark on all disk important incidents. All alarms can be grouped quickly and easily through the LCD menu. You can group video by alarms, clip to clip, date and time or manual fast forward or rewind. The text overlay feature allows you to overlay up to 20 characters which are viewed on screen during recording and playback – ideal for job management.

Downloading and Viewing Video

The Viperfish Nitro gives you several options to view recorded video. The hard drive trade named COMRAD is a combination reader and hard drive. COMRAD can be removed and connected to a desktop PC for viewing or emailing video clips. The Viperfish viewer makes viewing the videos easy. If you prefer to download video from Viperfish Land to a separate hard drive, it can be done fast through the USB 2.0 port. On the job you can connect a laptop or analog TV directly to a Viperfish Land for viewing high resolution video while you record.
