### Wireless
|
||||
|
||||
_Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a
|
||||
device over TCP/IP:
|
||||
|
||||
1. Connect the device to the same Wi-Fi as your computer.
|
||||
2. Get your device IP address (in Settings → About phone → Status).
|
||||
3. Enable adb over TCP/IP on your device: `adb tcpip 5555`.
|
||||
4. Unplug your device.
|
||||
5. Connect to your device: `adb connect DEVICE_IP:5555` _(replace `DEVICE_IP`)_.
|
||||
6. Run `scrcpy` as usual.
|
||||
|
||||
It may be useful to decrease the bit-rate and the definition:

||||
