A document camera (also known as a visualiser) is a video camera which can be used to display much more than just documents. It can be used to project and enlarge any fixed or moving object onto a big screen.
There are a few different brands and models of document cameras across our teaching spaces. The newer models have a richer feature set but all of our document cameras have the same basic capabilities.
They can be used in both local and videoconference teaching spaces.
Document cameras are a great presentation technology for visual learners and usage is only limited by your imagination.
You can show
Additionally students can learn by watching you write whilst also listening or contributing. Example scenarios include
If you are teaching by videoconference to students in another location you can step them through sharing their work with your room by using their document camera. They need to turn their document camera on, wait for it to run through its startup process, put their document on it, tap the touchscreen to bring it out of standby, press the Videoconference button, Transmit button then select Doc Camera from the Image to Send menu. The image from their document camera will be projected onto the wall screen in both rooms.
In the photo to the right the red light indicates that this particular document camera is in standby mode (off). When the button is pressed the light turns green to indicate the document camera is turned on and ready to use.
It will take two minutes after turning it on to project at its optimum brightness.
Best practice is to turn the document camera on, wait for it run through its boot up sequence and perform an automatic white balance (aka colour adjustment). After this process the document camera is ready for you to place your document or object on the document plate.
Videoconference to another site or single point recording of a local class
If delivering to another site by videoconference or recording a local class in a videoconference teaching space you must use the aqua button to display the image from the document camera to your remote site students or to have it recorded by CSU Replay.
If a blue screen is shown after selecting the document camera from the touch screen it is turned off. Press the power button to turn it on and wait a few seconds for it to start up and display the image.
The document camera shown in the photo above is a Samsung SDP 900 DXA. This model is installed in many teaching spaces. The instructions below are also based on this model.
This button is an image sharpness control. TXT Mode optimises material which is mostly words. IMG Mode optimises material with many pictures or colours.
Use the AWC button to correct any strange image colour issues.
The document camera does not reach optimum brightness until 2 minutes after it is turned on. For best results do not use the AWC button until then.
Use the Lamp button to select the lighting you wish to use
After freezing the image, you can remove your document or object while leaving its image displayed on the screen. Place your next document or object under the camera lens and press the Freeze button again. Your presentation continues without interruption.
