4K Ultra HD Imaging for Classroom Presentations

13-Megapixel CMOS Image Sensor

The TT-12S incorporates a 13-megapixel CMOS image sensor capable of capturing detailed documents and physical objects. Its effective resolution supports high-definition presentations where fine lines, printed text, and small visual details must remain distinguishable.

The camera delivers 3840 x 2160 video at 30 fps through its HDMI and USB outputs. For applications requiring smoother motion, it supports 1920 x 1080 resolution at 60 fps.

This flexibility allows educators to select a suitable resolution for displaying textbooks, artwork, handwritten notes, scientific demonstrations, and moving objects.

192x Total Zoom with 12x Optical Magnification

The integrated zoom system combines 12x optical zoom with 16x digital magnification for a maximum combined zoom factor of 192x.

Optical zoom adjusts the camera's lens to magnify subjects while retaining the detail available from the image sensor. Digital zoom provides additional electronic magnification when closer inspection is required.

The camera supports a maximum shooting area of approximately 18.5" x 10.2" in 16:9 format and 16.9" x 12.6" in 4:3 format.

This coverage accommodates documents, worksheets, books, diagrams, and larger presentation materials, while the zoom system allows the presenter to focus on specific areas.

Automatic and Manual Focus Controls

The TT-12S supports one-touch autofocus, zoom-synchronized focusing, and manual focus adjustment.

One-touch autofocus provides a convenient way to sharpen the image after repositioning a subject or changing the camera angle.

Manual focus offers additional control when displaying objects with different depths or when automatic focusing is unsuitable for a particular demonstration.

HDMI and USB-C Document Camera Connectivity

4K HDMI Output for Displays and Projectors

The ELMO TT-12S includes a standard HDMI Type-A output for connection to compatible projectors, interactive displays, monitors, and presentation equipment.

HDMI supports resolutions up to 4K Ultra HD at 30 fps or Full HD at 60 fps, allowing presenters to select the appropriate output for their display system.

This connection provides a direct video path for classroom demonstrations without requiring a computer.

USB-C Output for Computer-Based Presentations

A USB 2.0 Type-C device connection supports video and audio transmission to compatible computers.

The interface uses USB Video Class and USB Audio Class standards, supporting integration with compatible software applications.

This allows the TT-12S to function as a video source for computer-based presentations, instructional recordings, and supported video conferencing applications.

Simultaneous HDMI and USB Output

The TT-12S supports simultaneous output through HDMI and USB, allowing the camera image to be displayed on a connected monitor while also being transmitted to a computer.

This capability is particularly useful in hybrid classrooms where an instructor must display material locally while sharing the same visual content with remote participants.

HDMI Input Passthrough

An additional HDMI Type-A input accommodates a compatible external video source, such as a laptop or presentation computer.

The passthrough function allows users to switch between the document camera image and the connected external source through the camera's presentation system.

This arrangement simplifies installations that require both computer presentations and live document imaging.

Interactive Teaching and Presentation Functions

Highlight and Mask Tools

The TT-12S includes classroom presentation functions designed to direct attention toward specific visual information.

Highlight mode emphasizes selected portions of an image, while masking obscures areas that are not immediately relevant to the presentation.

These functions can help teachers guide students through reading exercises, worksheets, diagrams, and detailed instructional material. Certain functions require a compatible USB mouse.

Picture-in-Picture and Image Comparison

Picture-in-picture functionality allows presenters to display additional visual information within the presentation image.

The image comparison function supports side-by-side evaluation of visual content, making it useful for comparing documents, illustrations, and demonstration results.

These capabilities help educators organize visual information and demonstrate differences between subjects.

Microscope Mode

The integrated microscope function supports specialized close-up observation when the camera is configured with suitable microscope equipment.

This capability can be useful for science classrooms, laboratory demonstrations, and educational presentations involving small specimens.

Physical microscope attachment accessories are available separately.

Image Rotation and Freeze

The camera supports image rotation in 90-degree increments, allowing presenters to adjust image orientation without repositioning the entire unit.

The freeze function temporarily holds the displayed image, allowing users to change documents or prepare the next demonstration without immediately displaying those movements.

Flexible Camera Positioning and LED Illumination

Adjustable Arm and Rotating Camera Head

The TT-12S features an adjustable camera arm and movable camera head that accommodate different presentation angles.

The camera can be positioned above flat documents or adjusted to capture three-dimensional objects from alternative perspectives.

This flexibility supports demonstrations involving books, mechanical components, artwork, scientific equipment, and other physical teaching materials.

Integrated White LED Lighting

A built-in white LED illumination system provides additional light for subjects positioned beneath the camera.

This feature helps improve visibility when presenting documents or objects in classrooms with limited or uneven ambient lighting.

Foldable Design for Storage

The camera's adjustable structure can be folded into a compact configuration when not in use.

In its folded position, the TT-12S measures approximately 11.6" long, 7.7" wide, and 18.7" high.

The folding design supports storage in classrooms, AV equipment rooms, and shared presentation spaces.

Integrated Image and Video Recording

Capture Photographs and Videos

The TT-12S supports direct image and video recording to compatible USB flash drives and internal storage.

Still images are saved in JPEG format, while video recordings use MP4 format.

Video recording supports resolutions up to 4K, allowing teachers and presenters to preserve demonstrations and instructional materials for future use.

Built-In Microphone

An integrated microphone allows the camera to capture accompanying audio during supported video recording operations.

This feature is useful for recording narrated demonstrations and instructional content without connecting a separate microphone.

Direct video recording is unavailable while the camera is actively providing USB image output.
