Verdict

Pros & cons

Das Babysense Prisma ist ein Video-Babyphone mit 5-Zoll-Elterneinheit, das ohne WLAN, App und Abo direkt funkt. Die Verbindung hält auch durch Betondecken, und mit zwei Kameras siehst du zwei Kinderzimmer im Split Screen. Der Haken ist der Akku: Mit Dauerbild reicht er oft nur knapp eine Nacht. Hängst du die Elterneinheit nachts ans Netzteil, fällt das kaum ins Gewicht.

Pros

  • Verbindung hält stabil, auch durch eine dicke Betondecke ein Stockwerk höher
  • Läuft ohne WLAN, Konto, Cloud und Abo
  • Signalton bei Verbindungsabbruch, schwachem Akku und falscher Raumtemperatur
  • Split Screen zeigt zwei Zimmer, bis zu 4 Kameras koppelbar
  • Klares Bild auch bei Nacht, Kamera per Fernbedienung schwenk- und zoombar
  • Beide Kameras ab Werk gekoppelt, Einrichtung ohne Aufwand

Cons

  • Akku schafft mit Dauerbild die versprochenen 12 h selten, oft kaum eine Nacht
  • Akku fest eingebaut, nicht selbst tauschbar
  • Ton klingt flacher als bei manchen Marken-Babyphones
  • Im Split Screen ist nur eine Kamera zu hören
  • Leises Surren der Elterneinheit in stillen Nächten hörbar

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
