Description
The EDUCAM MULTIMEDIA video camera is especially designed to meet the various requirements in the edu-
cational eld. When it is connected to a professional monitor or simply to a TV set, EDUCAM is able to carry out
many different functions. It can be used in the following ways:
- as an episcope, for the reproduction of texts, documents, photographs, etc.
- as an enlarger, to enlarge small objects, insects, minerals, etc.
- for video-microscopy, connectable both to biological or stereo microscopes using the adapters included.
- as a overhead projector, for the projection of tracings
- as a camera for teleconferences, that can be connected to a computer and to the Internet
- as a camera for video-conferences, used in conferences, assemblies, meetings, etc.
- as a camera for lming, with the help of a video recorder.
This video camera enables you to record clearly even when there is little light available, thanks to its extremely
sensitive electronic circuits. The special lens enables you to focus from 0,76 mm, up to an innite distance.
At the camera base, there is an extremely sensitive microphone that, via the TV itself, or via a separate amplifying system, enables you to reproduce for example the teacher’s voice during the lesson, or to record sounds and
noises from the surrounding area.
The special exible arm and the heavy weight of the base, gives the EDUCAM its versatile, sturdy and stabile
characteristics. The micro-video camera placed on the end of the exible arm can be placed in any position,
even projecting from the base, without jeopardising the system’s stability. A special joint allows the head to rotate
avoiding connector breakages inside the exible arm.

Assembly
Power supply
The Educam Multimedia video camera requires 15 V DC working voltage and comes with an external power
pack. This power pack needs to be plugged directly into a 220 V mains sockets and its output cable should then
be plugged directly into the video camera power supply socket.
Video and audio signals
The analog video signal from the Educam video camera is transmitted to a TV monitor and the audio signal to
an amplifier or an amplified monitor. The small video/audio output signal cable, that can be found on the back of
the camera base, should be connected as follows:
Red plug (video signal):
into the video input of your monitor/colour TV directly or via the SCART adapter provided (in the yellow video
socket).
Black plug (audio signal):
into the audio input of your amplier system or into the audio input of your monitor/colour TV or via the SCART
adapter provided (in the white audio mono socket).
Using the SCART adapter, it has to be inserted into the SCART socket at the back of the TV set. See the TV
manufacturer’s instruction manual for details of how to switch on the TV and use its SCART circuit.

Operation
Switching on the video camera
The Educam video camera has a 3-position switch at the rear of its base. Each position corresponds to a specic function:
Central position “0” -> TV camera off.
Position “I” -> the yellow LED is lit and the Educam is operating with video signal only.
Position “II” -> both the yellow and green LEDs are lit and the Educam is operating with both video and audio
signals.
Using the video camera
Position the camera head with the lens and the electronic sensor directly in front of the object that you wish
to observe using its exible arm. The lens provided with the camera has a manual focusing and must therefore be adjusted every time the distance between the object and the camera is changed. This can be done by
simply turning the lens on the camera head. The object must be at least 0.76 mm away from the lens. There
are no limits to the maximum distance. To use the microphone to capture audio, put the camera base with the
microscope close to the audio source. It could happen that you hear a whistling noise while using the microphone. This whistle is not a defect of the Educam camera, but a normal audio effect (“Larsen effect”) that occurs when the microscope is to close to the loudspeakers and the microphone is receiving the audio from the
loudspeakers. The intensity also depends on the dimension and size of the room. The best solution to avoid
this effect is to place the Educam video camera far from the loudspeakers, to use a separated amplier system and place it in a room without reverb. The “Larsen effect” will decrease in a room with many people and
many pieces of furniture.
Capturing video from a microscope
The Educam video camera has been designed for effective use with microscopes.
The following special adapters (provided) are required for this application:
Adapter for biological microscopes: To be used directly in the optical tube of the microscope after having extracted the eyepiece. This adapter contains a WF10x eyepiece that needs to be replaced with the one belong-
ing to the microscope.
Adapter for stereo microscopes: To be used directly on one of the optical cylinders on a stereo microscope after having extracted the eyepiece. The biological microscope adapter needs to be inserted inside this adapter.

Descrizione
La telecamera EDUCAM è uno strumento espressamente progettato per soddisfare molteplici esigenze in ambito didattico. La telecamera EDUCAM MULTIMEDIA è uno strumento espressamente progettato per soddisfare
molteplici esigenze in ambito didattico. Collegata ad un monitor professionale o semplicemente ad un apparecchio televisivo, EDUCAM svolge il lavoro di molteplici apparecchi. Essa può essere utilizzata per le seguenti
applicazioni:
- come episcopio, per la riproduzione di testi, documenti, fotograe, ecc.;
- come ingranditore, per l’ingrandimento di piccoli oggetti, insetti, minerali, ecc.;
- come sistema di video-microscopia, collegabile sia a microscopi biologici che a stereomicroscopi grazie agli
adattatori forniti in dotazione;
- come lavagna luminosa, per la proiezione di lucidi;
- come telecamera per teleconferenze, per collegamento a computer e a internet;
- come telecamera per videoconferenze, per conferenze, assemblee, congressi, ecc.;
- come telecamera per la creazione di lmati, con l’ausilio di un videoregistratore.
Questa telecamera consente riprese nitide anche in condizioni di scarsa illuminazione, grazie all’elevata sensibilità dei suoi circuiti elettronici. Lo speciale obiettivo consente una messa a fuoco a partire da 0,76 mm no a
distanza innita.
Alla base è posto un microfono ad alta sensibilità che, attraverso il televisore stesso o un apposito impianto di
amplicazione, permette di riprodurre la voce dell’insegnante durante la lezione oppure di registrare i suoni e i
rumori dell’ambiente circostante.
Lo speciale braccio essibile e il notevole peso della base conferiscono a EDUCAM caratteristiche di versatilità,
robustezza e stabilità. La micro-telecamera posta all’estremità del braccio essibile può essere ruotata in qualsiasi posizione, anche a sbalzo rispetto alla base, senza compromettere la stabilità del sistema. Uno speciale
snodo permette la rotazione della testata evitando rotture dei connettori posti all’interno del braccio essibile.
