1INTRODUCTION
DVC Company, based in Austin, Texas, is a manufacturer of cost-effective, high performance digital video
cameras. We thank you for purchasing from the DVC-1412 product series.
This series of cameras is based on the premise that precise image processing applications demand mega-
pixel cameras that are optimized for the performance available from today’s leading-edge CCDs, while
maintaining an acceptable price to performance ratio.
The 2/3” interline Sony ICX285 CCD imager used in the DVC-1412 cameras has a 1392(H) x 1040(V)
progressively-scanned image format and has a pixel size of 6.45µm x 6.45µm. The CCD sensor has a
particularly high QE in the blue-green region of the spectrum resulting in higher sensitivity for most
applications.
The DVC-1412 series of cameras includes non-cooled, cooled, intensified, and multi-spectral versions.
Furthermore, a choice of I/O options is available: LVDS, CameraLink, or FireWire. Standard camera
features include high-speed shuttering, long-term integration, pulse driven integration, and gain/offset
control. All DVC cameras come with a standard 2-year warranty and use industry-standard “C-mount”
lenses.
This camera series also includes Intensicam II, which utilizes a gated, Gen III image intensifier, fiber-
optically coupled to the CCD.
With the LVDS version, the 10 frames/s video data is provided in a 12 bit parallel, differential LVDS
format, which is "plug-and-play" compatible with industry-standard image processors. The digital data,
pixel clock, enable line, and enable frame signals are accessible via the DB-44 connector.
The CameraLink version transmits 10 frames/s, 12-bit data over an industry standard MDR-26 interface to
any CameraLink compatible frame grabber.
In the FireWire version of the camera, the LVDS output is replaced by an industry standard 1394A
interface. The camera provides 12-bit data at 10 frames/s when used with any OHCI-compliant FireWire
interface card.
Computer-based control of gain offset is provided to "tune" the dynamic range of the camera to the
application. This provides an optimum match between the dynamic range and sensitivity of the camera and
the requirements of the application.
The CCD is physically mounted in the cavity of a high-precision opto-mechanical plate for excellent
mechanical stability. vibration applications. An adjustable C-mount coupling allows critical system
focusing adjustments. In-camera digitization using the stable CCD pixel clock eliminates pixel jitter,
improves repeatability, and enables sub-pixel accuracy in image processing applications.
DVCView, a Windows GUI software package is supplied with the camera, allowing image viewing and
control of all camera operations. Five user programmable, single-click software “buttons” allow the user
to customize the camera to the imaging application.
This manual applies to all of the DVC-1412 cameras.

2INITIAL INSPECTION
2.1 UNPACKING AND RECEIVING
These items were thoroughly tested and carefully packed in the factory. Upon acceptance by the
carrier, they assume responsibility for its safe arrival. Should you receive your DVC shipment in a
damaged condition, apparent or concealed, a claim for damage must be made to the carrier. To
return the product to the factory for service, please contact the DVC Customer Service Department
at (512)-301-9564 for a Return Material Authorization (RMA) Number. Returns are not accepted
without an RMA number.
If visual inspection shows damage upon receipt of this shipment, it must be noted on the freight bill
or express receipt, and the notation signed by the carrier's agent. Failure to do this can result in the
carrier refusing to honor the claim.
When the damage is not apparent until the unit is unpacked, a claim for concealed damage must be
made to the carrier immediately. Keep all cartons and packing materials. Since shipping damage is
the carrier's responsibility, the carrier will instruct you on filing the concealed-damage claim.
