I had issues with uploading videos, and so have included images to show visual fidelity of my £40 visualiser (which records in 60fps), the visualiser's height is such that you need to move the page to show a full A4 sheet - this is possibly undermining to my use case, but in reality allows for live demonstrations to support the delivery of the lecturer further.

For phones such as Androids, you can also connect to your computer and such using a wire, and then use your settings to find the setting allocated. (I would recommend researching your individual devices).

IOS allows you to connect your iPhone to your Mac and use a feature called continuity camera, which means you can use your iPhone as a visualiser if need be! I would recommend a stabiliser or tripod in that case though!

Another way to have a similar POV as a visualiser, you can use your phone as a webcam to be able to create a similar effect to a visualiser.

The teacher connects a graphics tablet (like a Wacom) or iPad to a computer. Then they place the device under the visualiser camera so students can see both the screen and the teacher’s hand movements on the tablet—this helps students understand how stylus pressure and gestures affect the digital outcome.

Student Work Feedback:
A student’s artwork can be placed under the visualiser for peer review or live critique, allowing the whole class to learn from each other's work.

Step-by-Step Breakdown:
The teacher pauses to show stages of the drawing, annotates directly on the paper, or uses overlay sheets to show changes step by step.

# data[].attributes.body
Close-Up Details:
The camera zooms in on fine details—like how to blend with a stump or layer graphite for smooth gradients. This helps students observe subtleties that are usually hard to catch from the back of a classroom.

# data[].attributes.body
Live Demonstration:
The teacher places a piece of paper under the visualiser and starts drawing in real time. The image is projected onto a screen or interactive whiteboard so the whole class can clearly see detailed hand movements, pressure control, and pencil strokes.

Visualisers, used over teams/zoom, are considerably less engaging to students than live delivery in person. This is the downside of online delivery in general - it's harder to engage students.

# data[].attributes.body
Visualisers are a common tool within essay subjects - a teacher can live-model writing as is required for any activity involving their live modelling - use of visualisers can be very interactive for students!

# data[].attributes.body
Visualisers are absolutely useful in an online delivery context. Visualisers, or tablets which you can write upon, are necessary for any teacher-delivered aspect of a lesson. A teacher can write and explain working live, using the visualiser. This allows for a normal lesson to be delivered, except online.

Visualisers are used for live maths delivery in any larger rooms (i.e. lecture theatres) as chalkboards, smartboards are too small for legibility

A generic article on 'using visualisers in the classroom', the selling points, what the look for in a visualiser model etc.

Visualisers are electronic devices with a height and tilt-adjustable camera on an arm that's connected to an external display like a TV or monitor. The camera lets you display a video feed on the display in real-time for interactive lessons and learning.

Visualisers have been in the classroom for over a decade however the technology has improved considerably over time. Modern visualisers have a small footprint and the latest connectivity solutions like Wi-Fi. By moving deskwork to 'the big screen' visualisers are one of the most powerful learning tools for all kinds of lessons.

Visualisers can also replace document projectors so long as you have an external display. Visualisers are cheaper and smaller than projectors and can be moved between classrooms easily. This makes them a better solution in small spaces.
How visualisers are used
When used for learning, visualisers are used to display items on a monitor. When used for document recording, they are used to take photos of student work. There are several ways to use visualisers, with these being the most common:
Live marking
Live marking is when a teacher shares a student's work with the class and marks it in real-time to show what's right and what's wrong. This helps students understand how they can improve on their own answers.
Live activities
Visualisers show a live feed on a monitor which can be used to show students how to do things. This could be a painting technique or an easy way to do arithmetic. Most students love to see how things are done rather than being told.
Demonstrations
Visualisers enable live demonstrations of all kinds of things, from circuit boards in DT to paintings in art and design and chemical powders in chemistry. This ensures students all see the same thing and learn together.
Document casting
Visualisers have replaced bulky document projectors in most classrooms because they are smaller and perform the same task. You can place a document under your visualiser's camera and display the feed on any connected display.
Document recording
Teachers can use visualisers outside of classroom hours to record documents and student work. Visualisers can capture photographs and record video. This is a sound way to record and protect student work from potential loss.
The best visualisers you can buy
Visualisers for classrooms are relatively inexpensive - a visualiser can cost as little as £140 including VAT. With visualisers, you pay more for a better camera sensor and optical zoom. The quality of the hardware is the key cost-driver.

If you intend to only use a visualiser for live marking, live activities, demonstrations and document casting and recording, and you do not need lots of zoom, you might like to check out the cheap as chips V500s Visualiser (£109 ex VAT).

The V500 Visualiser (£199 ex VAT) is an upgrade over the V500s, with a better camera sensor, one-touch autofocus and an impressive 100x digital zoom.

If you need lots of optical zoom, perhaps for scientific use, the Lumens PS 752 Visualiser (£817 ex VAT) is one of the best on the market with 20x optical zoom.

A cheaper alternative to the Lumens option is the Epson ELPDC21 Visualiser (£359 ex VAT) which makes do with 12x optical zoom.

Suffice to say, there's a visualiser for every budget. The best visualiser for you depends on what you'll be using it for. If you want a document camera, anything with digital zoom will be fine. If you want a scientific camera, you need optical zoom.

Still not sure about which visualiser to buy? We've got an expert article covering this very topic. You can find it here - how to buy the right visualiser.

Visualisers can allow for teachers to 'scan' a classroom more consistently than if they had their back turned, writing on a whiteboard. So, visualisers support behaviour management.

Visualisers, in comparison to smartboards/whiteboards, can cause a more complacent attitude in a teacher's delivery.

Visualisers require for teachers to be skilled with technology, and can be an additional technological 'point of failure' within the classroom.

Digital Innovation within Art - Using a Visualiser

Visualisers cost, and cost alot if you want one with high visual fidelity.

# data[].attributes.body
Visualisers allow for a teacher to show anything they please, particular to a maths context is that this can be used to show what a teacher’s work/working looks like on a page - hence allowing the teacher to model presentation of work on a vertical piece of paper, which is very necessary to do, in order to get the whole class on board with expectations surrounding presentation of work. The teacher could do an activity like this: “Please spend 30 minutes doing work, you have a test on friday and consider this revision time. I expect to see 30 minutes worth of work.” Then, do 20 minutes of maths questions on pieces of paper (you as a teacher should be alot quicker than them), spend the last 10 minutes watching the learners work (how quick do they work, how do they get distracted etc.). After the 30 minutes, show your work on the visualiser. Tell the students about how “30 minutes doing work” and “30 minutes worth of work” are different - you expect 30 minutes worth of work daily for revision (or whatever your expectations are), not 30 minutes ‘doing work’. This models two things for the learners: 1) Expectations about productivity. 2) How presenting maths work on an A4 sheet should go, presentation of work in an exam content is an enduring educational issue, and this is a great activity to support with this.

Visualisers allow for a teacher to model the appearance of maths working on a vertical piece of paper. Sounds silly, but it's essential for modelling expectations around presentation of work, and of productivity. The teacher could do an activity like this: “Please spend 30 minutes doing work, you have a test on friday and consider this revision time. I expect to see 30 minutes worth of work.” Then, do 20 minutes of maths questions on pieces of paper (you as a teacher should be alot quicker than them), spend the last 10 minutes watching the learners work (how quick do they work, how do they get distracted etc.).

Visualisers enable real-time demonstration of practical tasks, allowing students to observe detailed processes up-close. This is particularly valuable in subjects like art, science, and mathematics where intricate demonstrations are crucial for learning.
