HVS Camera Quick Start

Applies to: all USB-interface event cameras (e.g. CF-NRS1 Lingguang No.1). A USB camera can be connected directly to an X86 host (Windows / Ubuntu) or an ARM host. For each model's parameters see the product page.

1. Preparation

  • Interface and cable: you must use a USB3.0 interface and a USB3.0 cable that supports data transfer. USB3.0 ports are usually blue or marked "SS"; ordinary charging cables do not support data transfer and will cause the device to be unrecognized or drop frames.
  • Host: Windows 10/11, Ubuntu (22.04 recommended), or an ARM host.

Warning

Insufficient USB2.0 bandwidth causes event-data frame drops and abnormal replay speed. For how to confirm USB3.0 mode, Type-C cable orientation, and other common issues, see FAQ.

2. Connection and driver

Windows

  1. Connect the camera to the host via USB3.0; a USB Function Filesystem device should appear in Device Manager.
  2. Install the USB Function Filesystem driver; if the driver does not install automatically, restart into "disable driver signature enforcement" mode and install it. Detailed steps at MultiVision Studio — Driver installation.

Ubuntu / ARM Linux

The device has no USB access permissions by default; configure udev rules or grant temporary authorization:

sudo chmod -R 777 /dev/bus/usb/

For permanent permission configuration, see the troubleshooting section of Hybrid Vision Toolkit.

3. First run: MultiVision Studio

Once the driver is installed, run MultiVision Studio to open the device and preview the event stream and image stream in real time, record, and replay.

No camera?

Grab a .raw from Downloads — Sample recordings and play it back in MultiVision Studio to experience preview, EVT2→CSV export, and all other features.

4. Secondary development

All USB cameras are built on the same software and SDK (supporting X86 and ARM):

5. Networking and multi-device

USB cameras themselves have networking capabilities (common to all USB-camera models):
