Specification-based configuration

Four-camera visual-inertial capture

System overview

Built around
your research.

Expand the view of complex manipulation. Two camera modules share hardware synchronization for multi-view capture, with flexible mounting and an external battery.

30 FPS per camera: 4 x 1080P
IMU sampling: 300 Hz
Nominal system weight: Approx. 500 g

Configuration, lead time and delivery scope confirmed with your inquiry.

Design & capability

Designed for the task.

Modular visual-inertial capture

2 modules + 1 synchronization board. Field of view depends on lens choice, mounting angle and calibration, not camera count alone.

Calibration travels with the data

Factory camera and IMU calibration supports online and offline VIO workflows. Preserve calibration versions alongside the original recordings.

Designed for collection sessions

Combine local SD recording, USB output and Wi-Fi preview, with configurable alerts for storage, dropped frames and hands leaving the frame.

Specifications

Configuration details and measurement conditions.

Standard configuration
Cameras	4 x 1080P
Modules	2 modules + 1 synchronization board
Power	Approx. 5 W
Weight	Approx. 500 g
Nominal runtime	6 hours; test conditions to be confirmed

Horizontal / vertical field of view	60-210 degrees; configurable
TV distortion	2-20%; software correction supported
Image controls	Brightness, contrast, grayscale and switchable 3D noise reduction via Web UI / API
Anti-flicker	50 / 60 Hz, automatic or manual
Exposure / bit depth	Automatic exposure up to 15 ms / 8 bit
Stereo baseline	60 mm standard; mechanical customization available
Encoding	Motion JPEG / H.264 / H.265
Bitrate	Automatic or user-adjustable 14-28 Mbps

Inertial sensing and calibration
IMU	300 Hz
IMU-to-frame signal alignment	3 us
Factory calibration	Optical axes, camera intrinsics and extrinsics, IMU temperature and orientation

Status alerts	Missing card, full card and dropped frames; configurable lights, buzzer, USB and Wi-Fi notifications
Audio	Dual microphones, 48 kHz, basic AEC / ANS / AGC
Capture assistance	Configurable hand-out-of-frame alerts, automatic face masking and static-scene detection

Connectivity and maintenance
Interfaces	USB 2.0 High Speed / 5.8 GHz Wi-Fi
Preview / configuration	Live Wi-Fi preview and browser configuration; some changes require restart
Clients	iOS / Android / Windows / macOS
Updates	USB / Wi-Fi / SD OTA with power-loss recovery
Identity / clock	Unique serial number; RTC synchronization via Wi-Fi / USB
Minimum input	USB 5 V at 1 A; confirm the selected system power requirements
Battery	Replaceable lithium battery; hot-swap and operation while charging supported

Customization
Camera expansion	8 / 10 / 12 cameras using 4 / 5 / 6 modules and one synchronization board; project options
Optics	Wide-angle, fisheye or narrow-field lenses; recalibration required
ISP tuning	AE / AWB / gamma / sharpening / noise reduction; estimated adaptation 3-7 business days, not a delivery commitment
Mounting	Headband, chest, pole, helmet, wrist or distributed camera arrays
Cabling	Flexible coaxial MIPI, internal USB expansion and remote Ethernet camera heads with cables up to 1 m

2 / 4 / 6 cameras are standard configurations. Expanded arrays require confirmation of synchronization, weight, power, runtime and delivery scope.

Delivery and validation

Agree on the complete configuration.

Nominal specifications from the September 2026 v1.1 product documentation. Runtime, power, weight and synchronization depend on the confirmed configuration and test conditions. The 3 us IMU-to-frame figure is internal device alignment, not end-to-end synchronization with other devices.

Select camera count, lens field of view, mounting and target tasks.
Confirm firmware, serial numbers, calibration files and interface documentation.
Check exposure alignment, dropped frames, runtime and cross-device timing in the actual collection environment.
Retain raw video and inertial streams; store VIO, segmentation and annotations as traceable derived data.
