Verdict

Pros & cons

Das eufy Babyphone E21 ist ein Hybrid aus Video-Babyphone mit 5-Zoll-Monitor und App und liefert ein sehr scharfes 4K-Bild, auch nachts. Die Funkverbindung läuft per WLAN-Schalter ganz ohne Internet und warnt bei schwachem Signal. Der Haken: Der VOX-Modus meldet Weinen verzögert, und in Altbauten über mehrere Etagen reißt der Funk ab. Für dich passt es, wenn du dein Kind vor allem sehen willst.

Pros

  • Sehr scharfes 4K-Bild, Nachtsicht fast so klar wie am Tag
  • WLAN-Schalter trennt Kamera von Internet und Cloud, Monitor läuft weiter
  • Verbindungswarnung am Monitor bei schwachem Signal
  • Funk im Haus rund 53 m durch acht Wände
  • Kamera schwenkt 330° und neigt 60°, zweite Kamera koppelbar
  • Niedrige Strahlung: 0,85 V/m knapp 1 m vor der Kamera

Cons

  • VOX-Modus meldet Weinen oft erst nach 10 bis 30 Sekunden
  • Funklöcher in Altbauten und über mehrere Etagen
  • Monitor zeigt nur 720p und hält mit Dauerbild knapp 9 h
  • Monitor geht bei leerem Akku ohne Warnton aus
  • Monitor schaltet sich auf der Ladestation ungewollt ein

Das Momcozy BM04 ist ein solider Hybrid mit starkem Bild: Die 5-Zoll-Elterneinheit läuft per Funk ohne Internet, die App zeigt das Kinderzimmer auch von unterwegs. Die Funkstrecke reicht über zwei Stockwerke bis in den Garten. Der Haken liegt bei der Kamera: Sie wird teils sehr heiß und braucht nach Aussetzern einen Neustart von Hand. Wenn du nachts ohne jeden Zweifel geweckt werden willst, prüfe sie in den ersten Wochen genau.

Pros

  • Scharfes 1080p-Bild mit Infrarot-Nachtsicht auf 5-Zoll-Display
  • Elterneinheit läuft per FHSS-Funk ohne WLAN, Konto oder Server
  • Signal reicht über zwei Stockwerke und bis in den Garten
  • Kamera schwenkt 350° und neigt 110° per Tasten der Elterneinheit
  • Bis zu 4 Kameras koppelbar, Anzeige im Split-Screen
  • Akku hält 20 h im VOX-Modus, 10 h mit Dauerbild

Cons

  • Kamera wird in mehreren Fällen sehr heiß, einmal schon nach 2 h
  • Etwa alle acht Wochen Neustart nötig, sonst bleibt der Weckruf aus
  • Mehrere Erstgeräte mit Verbindungsproblemen oder Defekten getauscht
  • Kamera ohne Akku, Wandhalterung nur zum Bohren
  • Bewegungsalarm nur per App, Display in direkter Sonne kaum lesbar
