Page 6: Important Precautions
Important Precautions To ensure continual high performance from the camcorder take the following precautions into consideration: Avoid very damp places. If the environment is wet or damp a rain cover must be used to protect the unit. Do not subject the unit to severe shocks or vibration. Do not expose the camera to extremes of temperature.
Page 7 Warning If the camera is in a wet or damp environment, a rain cover must be used to protect it for personal safety reasons (EN60065). The optional rain cover protects the camera according to safety specification EN60529 up to level IPX2 (spraying water). FCC Class A Statement This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instructions,...

Page 9 Section 1 Introduction This section describes the FilmStream mode of operation and outlines the technology used in the Viper. The access and security features of the camera are also explained. Contents Selecting operational mode ............. 1-2 Streaming modes ................1-3 Technology ..................
Page 10: Selecting Operational Mode
Selecting operational mode To operate in the FilmStream mode you must ensure that the camera is switched to this mode. The output signals and the control functions that are available depend on the mode you select. The factory default for the mode setting is the FilmStream mode, so normally you do not have to switch modes to operate the camera as a digital film camera.
Page 11: Streaming Modes
Streaming modes FilmStream mode The FilmStream mode differs from the HD video mode in that it captures all information in a scene and stores it digitally without altering any parameters. By avoiding video processing in the raw RGB data, the output signal is a true and faithful representation of the light from the scene.
Page 12: Technology
Technology CCD sensor technology The Viper FilmStream Camera uses three unique 9.2 Megapixel HD- DPM+ CCD sensors that allow the camera to work in several formats; 1080 lines at 24/25/30 frames per second or 720 lines at 24/25/30/50/ 60 frames per second. This CCD sensor is based on the Frame-Transfer principle which is best suited for progressive images.
Page 13 • 1080i When eight vertical sub-pixels are combined, the total line count becomes 540 lines. The second field is shifted four pixels to give an interlaced picture. • 720P When six vertical sub-pixels are combined, then the total line count becomes 720 lines.
Page 14: Access And Security
Access and Security Camera cards Three camera cards are delivered with each camera; one owner’s card and two user cards. An owner’s card is linked to the serial number of the camera and is unique to that camera. It cannot be used as an owner’s card for another camera.
Page 15 Access control The owner’s card or the PIN code is used to access special set-up and security features of the camera. Inserting the owner’s card into the camera gives direct access to the Security menu. If you select the Security menu without this card inserted, you must enter the correct PIN code to gain access to this menu.
