Projectors
(a.k.a. LCD Projector, Video Projector, Digital Projector, Laser Projector)
A data projector is a projector which transmits an image from a source and projects it on to a screen.
- Projectors are located in all lecture halls and classrooms containing AV equipment either mounted from the ceiling or the back of the room
- They can only be turned on and off by using the Crestron touch panel on the podium, control buttons inside the AV box or cabinet, or the supplied remote control as all physical projector buttons have been disabled
- Projectors are able to display images from the on board computer, document cameras and DVD/ Blu Ray players. You may also connect your own device using our BYOD connections.
Control Panels
A Crestron touch screen control panel is the main source for users to control the AV system and to switch sources.
Use this panel to access the following:
- Log in to the AV system with code provided by CCT
- Turn the AV system on and off
- Electronic lock to open the podium to access Wireless Microphones and Blu Ray Player
- Lower the screen and turn on projector
- Display various sources - Compter, Laptop, Blu Ray player, and Document Camera
- Adjust audio volume for selected Sources and Microphone(s)
- Hide or show projector image without turning the AV system off
Computers
- Log into the computer using your Mac ID and password
- All computers are using the Windows 10 OS
- Computers have multiple USB ports for Thumb Drive and Wireless Presenter (iClicker) connections
- Wi-Fi for playing YouTube videos and Internet access
- Display your infomation on the projector screen with installed Presentation software such as Microsoft Office, VLC Media Player and iClicker
- Access Avenue to Learn for displaying online courses
- Sign out when finished to avoid access to your personal information!
Microphones
Lavalier Microphone
This syle of microphone allows you speak from anywhere in the room without having to hold a microphone and your voicewill still be heard by everyone in the room. You can effectively speak to students during a lecture while being able to keep your hands free. This allows you to communicate more expressively and approach any audience member for a more personal interaction when needed.
For optimal sound quality, we reccommend clipping the microphone to your shirt, below your chin.The microphone cable plugs into another device, a transceiver, which clips to another piece of the speakers clothing, usually a belt, pocket or waistband. The transceiver is battery operated and must be turned on before use.
Podium Microphone
A permanent microphone that sits atop a podium which transmits your voice to the students by way of the speaker system. The lecturer needs to be in close proximity to the podium for effective transmission of their voice.
Handheld Microphone
Similar to the lavalier mic, a handheld allows you to walk around the room while holding a microphone. The lecturer can easily adjust how close they are to the micrphone for the best sound quality.
Document Cameras
A document camera is a real-time image capture device for displaying an object to a large audience.
How you can use this technology:
- Document cameras are connected to in-room data projectors so that instructors can project objects such as handwritten documents, books, objects and transparencies
- Features an overhead light and an optinal zoom lens, allowing you to zero in on small print or illustrations.
- New sheets can be quickly swapped in by first removing the old set.
Overhead Projectors
An overhead projector is a variant of the slide projector that is used to display images to an audience, usually on a large screen.
How you can use this technology:
- You can project hand drawn images, equations and other content which you have created on transparent sheets, onto a surface, commonly a projection screen at the front of the room.
- In addition, you can also use multiple sheets, in a layering affect, which allows you to add and remove certain content for visual affect.
- Since there is no need to secure the transparent sheets to the overhead projector, new sheets can be quickly swapped in by first removing the old sheet
DVD & Blu-ray Players
DVD’s and Blu-ray Discs are an optical disc storage medium, and allow you to play video programs using DVD and Blu-ray players.
- Blu Ray players are located in all Lecture Halls and some classrooms. DVD players are located in the rest of classrooms containing AV equipment
- You can access the players by opening the Podium or Black Box containing the AV equipment, using the code supplied by CCT
- There are 3 ways to control the players. You can use the front panel controls, the remote control or the Crestron touch panel controls located on podiums,.
- Not all DVD'S or Blu Ray discs may play on every player due to specific regions or "homemade" discs. You may want to do a trial run before your class to make sure the presentation is operational.

Digital Annotation
Allows instructors to label and mark up text, images, songs, websites, videos, and more.
How you can use this technology:
- Classrooms equipped with the SMART Podium interactive pen display lets instructors and professionals present while writing notes or illlustrations. Some of the newer displays offer a cordless pen on the 24" touch screen.
- SMART Ink lets presenters write over websites, videos and into PDFs and Microsoft Office files, and save notes in almost any file type. And these annotations are displayed on the projector screen.
- The display features 4 pre-set buttons for writing (black, blue, red and SMART ink), plus highlighter colours and pen widths so presenters have almost unlimited ways to illustrate key concepts.
