1 Description and operation
1.1 Function of the product
Stereo video camera "the BlackBird" (further in the text "camera" or "product") allows to get threedimensional image.
By using two identical parts, the camera generates a signal in interlaced 3d format.
Video image in this format can be transmited through analog video transmitter, capable of recording
video with help of capture devices, to display through 3D video glasses, through 3D-TV set or 3Dprojector (hereinafter «the video receiver»).
Camera is designed for installation on the radio-controlled models and toys. You can also use it in
the surveillance system.

Indication of giving of supply is made by the light-emitting diode 3 located on the face of the main
board 6.
Interface connector 9 provides voltage to power the camera and get video images. Numbering of
contacts of the socket is made from right to left (see figure 1b). First contact plus 12V, second pin GND
(it is common for power and video), the third contact - video output.
Connection to the power supply and the receiver of video signal is made by the interface cable
shown in figure 1c. Default cable length is 200mm. Interface cable supplied, does not have video and
power connectors. The cable is purchased separately.
1.5 Device and operation
The basis of video camera is made by two sensors and their optical system. Signal from a sensor
switched alternately, thus, signal is generated in the format interlaced 3D. Then the signal is amplified
and transmitted to the interface connector.
1.6 Measurement tools, instruments and materials
The main tool that you require to use for the camera is Phillips screwdriver. It is used for setting the
vertical offset and focusing lenses. It Is used for loosening the screws securing the lenses and their
holders.
Additional materials:
The interface cable with previously installed connectors. The cable has three connectors.
Interface MU-3F to connect to the camera, slot DJK-A for power supply and RCA Jack for
connection to a display, or video transmitter. Cable length is 200mm.
Pencil lens-cleaning. It is used for cleaning the lens from dirt (see figure 2B). The flat side of
the pencil is used to clean the lens from dirt. The brush is used to clean the lens from dust.
Cable for connection cards camera together. Cable length is 200 mm. You can order cable of any
length, but not more than 2m.
As a means of measurement resolution it is used a special table. For example, EIA1956 or another
for resolution of at least 600 TVL (see figure 2a).

2 Intended use
2.1 Operating limits
Operating temperature of the camera is in the range from -20 to +70 degrees Celsius. If you want to
use at other temperatures, it is needed to organize additional cooling or heating to ensure an
acceptable temperature.

The camera is made in case less form and is not protected from moisture. Protection class sensors
IP50, class of protection, other components IP00. For use in humid environment it`s needed to protect
from moisture.
2.2 Preparing to use
Before work it is necessary to connect the camera to the video signal receiver and then to the power
supply.
Connecting of the video output to the receiver signal is realized directly. Output of the camera is
connected to the composite video input of the receiver signal. Often it is the yellow RCA Jack. Central
contact RCA connector connects to the third contact interface connector (yellow wire), and side contact
RCA connector to the second contact interface connector (black wire).
Do not connect the video output to the audio input Jack. Usually it is Jack to RCA of red or white
color. It doesn`t cause damage, but the image on the receiver of the signal will not be.
For supply of the camera it is acceptable to use external power supply DC voltage from 5 to 12V. As
the power supply, you can use:
1. From 4 to 7 batteries (1.5 V), which connected in series
2. From 5 to 9 accumulators NiMH, NiCd (1.2V), which connected in series;
3. From 2 to 3 accumulators LiIon, LiPo (3.6V), which connected in series;
4. 1 lead acid accumulator with voltage from 6V to 12 V;
5. The stabilized power supply of direct current with voltage from 5 to 12 V and with current more
than 150 mA.
Positive power source contact connects to the red wire interface cable (first contact of the
connector), negative connected to the black wire interface cable (second pin connector).
Note! Observe the polarity and accuracy of connection to the power source. Connection of the
supply voltage to the output or wrong polarity will lead to damage the
camera.

2.3 Product use
Camera that is configured and correctly connected starts immediately after power-up. LED (see
figure 1a, item 3) indicates that power is supplied.
Before long use of the camera, you have to verify the absence of vertical offsets. For this purpose it
is enough to disable the 3D mode on the video receiver and visually to appraise the offset of the left and
right image relative to each other. If there is noticeable offsets to configure according to 3.2.
3 Product maintenance
3.1 Setting focus lenses
To adjust the focus you need to do the following actions::
Loosen the fastening screw of one lens (see figure 1a, item 8);
Rotate the lens until the image is clear for the desired distance;
Fix the lens with screw;
Repeat for the second lens.
3.2 Adjusting the vertical offset images
Vertical offset of the image is poorly perceived by human. If there is offset, it`s possible rapid eye
fatigue and incorrect perception of the volume.
To perform the setting you need to prepare the camera for use (see p.2.2), disable 3D mode on the
receiver of the signal and visually appraise the offset of the left and right image relative to each other.
Figure 4a shows the image from the adjusted camera, without vertical offset. There is only
horizontal offset caused with the mixing of the optical axis of the lens (convergence).
Figure 4b shows the image which is not properly configured camera. There is only the vertical offset.
For correction of offset loosen the screws of the holders of the lens (see figure 1b, item 7), move
them to reduce offset images and fix it again. After fixing to appraise the offset of the image again. If it is
necessary, adjust the focusing of the lens.
When you spread cards of camera using the extension cable also need to remove the vertical offset
by turning and safe fixing the cards.

3.3 Configuring convergence
Convergence is the angle between the optical axis of the lens and the left and right camera.
If the optical axis of the lens intersect on a monitored object, in this place will be missing the
horizontal offset of the image. The object will be visible on the screen plane.
If the optical axis of the lens intersect behind the object, it will be visible in front of the screen, and if
before the object - behind the screen.

To configure the convergence it is necessary to tilt the lens to each other or apart. There are no
special instruments of fixation of convergence on the product. For fixing it is necessary to firmly secure
the cards of camera during installation.
