• 🖥️ IP cameras with USB adapter - some models (Xiaomi Mi Home Security Camera) support connection via an adapter.

Important: DSLR cameras And mirrorless cameras They often do not transmit video via USB in real time without additional software. For example, Canon And Nikon offer official streaming utilities, and Sony may require use Imaging Edge Webcam.

Cable and ports: what do you need to connect?

A mistake many users make is using the wrong cable. Even if the connector is physically suitable, the camera may not work due to insufficient data transfer speed or lack of support UVC (USB Video Class).

Here's what to consider:

• 🔌 USB port type:
  • USB 2.0 — sufficient for most webcams (max. resolution 1080p).
  • USB 3.0/3.1 - needed for 4K cameras or DSLR in video mode (for example, Canon EOS R5).
  • USB-C - modern laptops (MacBook Pro, Dell XPS) may require an adapter.
• 🔗 Cable type:
  • For GoPro - cable USB-C → USB-A (usually a short one is included in the kit).
  • For Canon/Nikon - original cable (for example, Canon IFC-600PCU).
  • For old cameras - 可能需要 Mini-USB or Micro-USB.

Camera type	Recommended cable	Max. USB resolution	Is software required?
Webcam (Logitech C922)	USB-A → USB-A (included)	1080p/30fps	No
DSLR (Canon EOS 90D)	USB-C → USB-A (original)	1080p/60fps	Yes (EOS Webcam Utility)
Action camera (GoPro Hero 10)	USB-C → USB-C (length <1m)	1080p/60fps	Yes (mode Webcam)
Video camera (Sony HDR-CX405)	Micro-USB → USB-A	720p/30fps	Yes (setting USB Stream)

Critical detail: The cable length should not exceed 1.5–2 meters for USB 2.0 and 3 meters for USB 3.0. Longer cables may cause signal delays or dropouts.

⚠️ Attention: Some cameras (eg Sony A7 III) block video transmission via USB without activated mode «USB Streaming» on the menu. Check your camera settings before connecting!
