Visualiser Buying Guide
Capturing, saving and sharing images and video of physical objects, texts, live experiments or even animations are easy with a visualiser.
No longer are educators limited to huddling around a table or needing to use up valuable time converting physical objects to digital images to use within a lesson. Due to the variety of benefits each visualiser has, choosing the one for you can be a drawn-out task.
That’s why our guide aims to break down these benefits to help you find your new classroom best friend.
Key features to look out for:
Simplicity to Revolutionise the Way You Teach
Visualisers are meant to make the life of an educator easier. If its pure simplicity you are looking for in order to capture and share images within your class, then USB visualisers are a great option with their plug-n-play convenience. Simply connect your visualiser (also known as a document camera) to any interactive whiteboard or projector to instantly give students a learning experience based on collaboration.
For those using a visualiser where precise positioning of the visualiser’s camera is essential, then a visualiser with a focus on its flexible arm may be a good choice. As they are designed to make precise camera movements incredibly straightforward with their ability to flex and bend.
To combine absolute flexibility and mobility Consortium are pleased to bring to market the AVer F70W, which supports both wired and wireless transmission. Allowing educators and students to interact at levels never experienced before with the ability to present live images or video from anywhere, indoor and outdoor, all you need is a device to display the captured content.
Maximum shooting area & image quality
The most important influence when choosing a visualiser is the image quality, this is determined by the resolution. Higher resolutions mean that there are more pixels per inch, creating a high-quality, crisp image.
When determining the image quality you need, you will want to assess the size of the screen you intend to display on. The bigger the screen, the higher the resolution you will need.
Here are the common resolutions and their native aspect ratios:
1024 x 768
Pixels – 4:3
WXGA or HD Ready
1280 x 800
Pixels – 16:10
Full HD 1080p
1920 x 1080
Pixels – 16:9
Pixels – 16:10
3840 x 2160
Pixels – 16:9
Smooth Video Performance
The way a visualiser handles motion is called frame rate and describes how often a device captures images. In our catalogue and on our website visualisers will highlight frame rate in frames per second (fps). The higher the fps the higher the number of images that can be captured.
You want a powerful engine within your visualiser to eliminate lag and ensure there is no jerky motion in order to create a free-flowing video. Consortium’s range of visualisers can shoot up to 60fps at Full HD resolution and 30fps at 4K UHD to support your teaching.
Closer Than Close
The zooming capability of a visualiser opens up a whole new world as you are able to display the smallest objects with incredible detail often not visible to the human eye. The capability can be determined both by its optical and digital zooming function.
A digital zoom takes just the centre portion of an image picked up on the cameras image sensor and scales it up capturing fewer pixels. In contrast, an optical zoom magnifies the image to fill the entire image sensor capturing a zoomed image at the maximum number of pixels.
Capture it, Save it
The videos and photographs you create can be captured and saved for future use. Save either to the on-board memory or to an SD card, or simply transfer them to a PC using a USB cable.
