+# Kamera Sony alfa 5000
+
+wlan-SSID: ```DIRECT-kxE0:ILCE-5000```
+
+Passwort: variabel
+
+Wahrscheinlich wird das Passwort nach eineiger Zeit ohne Strom zufällig neu gesetzt.
+
+Die sicherste Methode ist daher, nach dem Einschalten der Kamera ein Bild vom HDMI-Stream zu machen und den QR-Code auszulesen.
+
+## Bild aufnehmen
+
+Mit ffmpeg:
+
+```
+ffmpeg -i rtmp://192.168.1.168/live/0 -vframes 1 -f image2 -y img.jpg
+```
+
+## QR-Code auslesen
+
+Mit zbar-tools:
+
+```
+sudo apt-get install zbar-tools
+zbarimg img.jpg
+```
+
+Ausgabe:
+
+```
+QR-Code:W01:S:kxE0;P:nEfVEq6X;C:ILCE-5000;M:B272BF3F42B1;
+scanned 1 barcode symbols from 1 images in 0.1 seconds
+```
+
+Daraus ergibt sich der SSID-Name: `DIRECT-kxE0:ILCE-5000`
+
+und das Passwort: `nEfVEq6X`

+sudo apt upgrade
+```
+
+Konfiguration anpassen:
+
+```
+sudo raspi-config
