Connect iVCam via USB
Get the most stable, lowest-latency connection by using a USB cable. No WiFi required — just plug in and stream in seconds.
Why Choose USB Over WiFi?
USB connection eliminates network variables entirely — giving you rock-solid stability ideal for live streaming, recording, and professional video calls.
Zero-Lag Streaming
USB transmission bypasses your WiFi network completely, delivering the lowest possible latency. No buffering, no dropped frames — just smooth, real-time video every time.
No WiFi Required
USB works even without a network. If your router is unreliable, your WiFi is shared with many devices, or you simply don't have internet access — USB keeps you connected.
Charges Your Phone
While streaming via USB, your phone stays plugged in and charging. No more worrying about battery drain during long streaming sessions or video calls.
What You Need for USB Connection
Gather these essentials before starting. The setup process differs slightly between iOS and Android devices.
Windows PC + iVCam Client
Download and install the iVCam Windows PC client (v7.3.9). Supports Windows 7/8/10/11 (64-bit recommended). The client creates a virtual webcam driver recognized by all video apps.
iVCam Mobile App
Install the iVCam app on your iPhone (iOS 13+) or Android phone (Android 5.0+). The mobile app captures video from your phone's camera and transmits it to the PC.
USB Cable
For iOS: use an Apple Lightning or USB-C cable (MFi-certified recommended). For Android: any USB cable that supports data transfer — not just charging. iPhone 15 Pro+ supports USB 3.0 for faster speeds.
How USB Connection Works
iVCam uses the USB connection to tunnel video data directly from your phone to the PC, bypassing the network entirely. The process is automatic once your device is properly configured.
Prepare Your Device
iOS: Install iTunes (desktop version). Android: Enable USB Debugging in Developer Options and install the correct USB driver for your phone brand.
Connect via USB Cable
Plug your phone into your Windows PC using a data-capable USB cable. Make sure to select 'Transfer files' (Android) or trust the computer (iOS) when prompted.
Launch iVCam PC Client
Open the iVCam PC client on your Windows computer. It automatically detects your phone connected via USB and switches to wired transmission mode.
Stream via USB
Your phone's camera feed streams to the PC instantly over USB. Select 'e2eSoft iVCam' in Zoom, Teams, OBS, or any video app to start using it as your webcam.
iOS USB Setup Guide
Setting up USB for iPhone or iPad requires iTunes to establish the Apple USB device service. Follow these steps carefully.
Install iTunes (Desktop Version)
iTunes must be installed on your Windows PC to establish the Apple Mobile Device USB Driver — which iVCam uses to communicate with your iPhone over USB. You must install the desktop version from Apple's website, NOT from the Microsoft Store.
- Download iTunes directly from apple.com/itunes or the Apple support page
- Do NOT install iTunes from the Microsoft Store — it won't install the required driver
- If you previously used software like iMazing, iTools, or 3uTools, they may have installed a conflicting libusb-win32 driver
- After installing iTunes, restart your PC before connecting your iPhone
Connect iPhone and Trust the Computer
Connect your iPhone to the PC using a Lightning or USB-C cable. When you see the 'Trust This Computer?' prompt on your iPhone, tap 'Trust' and enter your passcode. Your iPhone should now appear in iTunes.
- Use an Apple-original or MFi-certified cable for best compatibility
- If the Trust prompt doesn't appear, try a different USB port (prefer back-panel ports over hubs)
- iPhone 15 Pro and later support USB 3.0 — use a USB 3.0 port and cable for higher bandwidth
- Check apple.com/HT204095 if your phone doesn't appear in iTunes
Verify in Windows Device Manager
Open Windows Device Manager (Win+X > Device Manager) and confirm your iPhone appears correctly. You should see 'Apple iPhone/iPad' under 'Portable Devices' AND 'Apple Mobile Device USB Driver' under 'Universal Serial Bus controllers'.
- If you see 'iPhone (Composite Parent)' under 'libusb-win32 devices', a conflicting driver is installed
- To fix: right-click the conflicting device > Uninstall device > check 'Delete the driver software' > OK > reconnect phone
- After uninstalling the conflicting driver, open iTunes and let it reinstall the correct Apple driver
- Make sure the 'Apple Mobile Device Service' is running in Windows Services (services.msc)
Open iVCam and Connect
With your iPhone connected via USB and recognized in iTunes, open the iVCam PC client. It will automatically detect the USB connection and prioritize it over WiFi. The connection is established within a few seconds.
- iVCam automatically prefers USB over WiFi when a USB connection is detected
- If it connects via WiFi instead, disconnect your phone from the WiFi network or move out of range
- The PC client status bar will indicate 'USB' next to the connection status when using wired mode
- You can also verify by disconnecting the WiFi on your phone — USB should remain active
Android USB Setup Guide
Android USB connection requires enabling Developer Options and USB Debugging. This unlocks the ADB (Android Debug Bridge) access that iVCam uses for USB streaming.
Install USB Driver for Your Phone
Windows needs the correct USB driver for your Android phone brand before it can recognize the device. Most manufacturers provide official drivers through their mobile assistant software.
- Samsung: Install Samsung Smart Switch or download the driver from samsung.com
- Google Pixel: Install the Google USB Driver from developer.android.com
- Other brands: Search '[brand] USB driver Windows' or check developer.android.com/studio/run/oem-usb
- After installing the driver, your phone should appear in Device Manager as 'USB storage' or 'Media device'
Enable Developer Options
Developer Options is hidden by default on Android 4.2 and later. You need to unlock it before USB Debugging becomes available. This is a one-time process.
- Go to Settings > About phone (or About device)
- Tap 'Build number' exactly 7 times until you see 'You are now a developer!'
- Enter your phone PIN if prompted
- Developer Options will now appear in Settings (sometimes under Settings > System > Developer options)
Enable USB Debugging
USB Debugging allows iVCam to establish an ADB connection with your phone over USB. Without this, the app cannot stream video via cable.
- Go to Settings > Developer options and toggle 'USB Debugging' to ON
- Also consider enabling 'Stay awake' to prevent your phone from sleeping while plugged in
- If you can't find Developer options, try Settings > System > Advanced > Developer options
- USB Debugging is safe — it only allows ADB commands from trusted connected computers
Connect and Set USB Mode
Plug your Android phone into the PC via USB cable. When the notification appears asking for USB connection type, select 'Transfer files (MTP)' or 'Transfer photos (PTP)' — NOT 'Charging only'.
- Swipe down to see the USB notification; tap it to change the connection type
- Select 'Transfer files (MTP)' for most Android phones
- Some phones show this as 'File transfer' or 'Media device'
- If you don't see any notification, check your phone's Developer options to enable USB connection prompts
Allow USB Debugging from This Computer
When you open the iVCam PC client for the first time with USB Debugging enabled, your phone will show a prompt asking you to allow USB debugging from this computer. You must approve this for iVCam to connect.
- Tap 'OK' (or 'Allow') when prompted — check 'Always allow from this computer' to skip this step next time
- If the prompt doesn't appear, try: revoke USB debugging authorizations in Developer options, then reconnect
- If it still doesn't appear: toggle USB Debugging off and on, or reboot your phone
- Once approved, iVCam will automatically connect and stream video via USB
USB vs WiFi Connection
Both methods work with iVCam. USB is the gold standard for stability; WiFi is more convenient. Choose based on your use case.
USB (Wired)
Most Stable- Zero-latency, rock-solid connection
- No dependency on WiFi quality or router
- Best for live streaming and recording with OBS
- Charges your phone while streaming
- Requires a USB cable connected at all times
- Limited mobility due to cable length
WiFi (Wireless)
Most Convenient- No cables — move freely while streaming
- Quick setup with automatic device discovery
- Works across rooms with strong WiFi signal
- Perfect for video calls and meetings
- Depends on your local network quality
- May experience lag on congested networks
Optimize USB Streaming Quality
USB already delivers excellent performance — these tips will help you squeeze out every last bit of quality and stability.
Use a USB 3.0 Port
For iPhone 15 Pro and later (which support USB 3.0), connecting to a USB 3.0 port on your PC provides significantly faster data transfer and supports higher bitrates. Use the blue-colored ports or check your PC specs.
Use Quality Cables
Use Apple-original or MFi-certified cables for iPhone. For Android, use the cable that came with your phone or a quality data cable. Cheap cables can cause frequent disconnections and bandwidth issues.
Enable HEVC Encoder
Select HEVC (H.265) in the iVCam app settings if your phone supports it. HEVC provides better compression — same quality at lower bandwidth — which helps with USB 2.0 connections that top out at 1080p/60fps.
Connect to Motherboard Ports
Plug directly into USB ports on the back of your PC's motherboard rather than front-panel ports or USB hubs. Back ports have dedicated USB controllers and offer more stable connections.
Match Bitrate to USB Version
USB 2.0 reliably supports up to 1080p/60fps. If you experience lag or disconnections at higher settings, lower the resolution to 720p/30fps to reduce bandwidth demand. USB 3.0 supports higher resolutions and frame rates.
Enable Stay Awake (Android)
In Android Developer Options, enable 'Stay awake' to prevent your phone from sleeping while plugged into USB. This avoids connection interruptions during long streaming or recording sessions.
