Bin sehr zufrieden, leicht zu montieren. Guter Winkel so schlüpft keiner rein, der nicht gehört wird. Verschiedene Melodien und Lautstärken.

This product is very good, I use this product in my house and I like that I can hear anyone that comes through the door, the bell is very loud and there is many options for sound. The battery life is also very long and it’s very cheap. If you need a reliable bell buy this product!

Conforme à la description et de fabrication et conception correctes, ce détecteur de mouvement à carillons est vraiment simple à installer et à faire fonctionner 👍Polyvalent, on pourra aussi bien l'utiliser à la maison, notamment en été comme système d'avertissement lorsque l'on laisse porte ou fenêtre ouverte, mais également pour des locaux professionnels comme un magasin pour avertir de l'arrivé d'un client.Pour 32.99€ au moment de mon commentaire, on a un rapport qualité prix correct.Merci de m'avoir lu 😉

Amazing range on this, over a hundred feet down my driveway and it activates the alarm inside an hidden spot in my house... I expected to have to keep the alarm in my window, but I can put it anywhere, and that's a good thing because it can be powered by micro-USB instead of having to keep AA batteries in it and charged up. I've just tucked it inside my entertainment unit and bingo, done... Hassle free.Lots of different alarms, from real long to real short musical tunes, or Hello Welcome in English and a few other languages. You can also set it to vibrate. You can adjust volume from loud to kinda quiet (not super quiet though)The sensor also has the micro-USB option but for me it's not feasible, it uses 3 AAA batteries instead.They all can be deactivated, so animals don't keep you up at night... or if you have a very windy storm.I'll note that you see from my pictures that I've set this up outside (the sensor) I have to protect it from the weather otherwise it won't hold up... this is intended for indoor/sheltered use.In cold weather the sensor's detection range is quite large.. maybe exceeding the claimed 8m.Over all, this product is great, and it exceeded my expectations.If there is a downfall, it's that is no way to program the sensitivity levels, nor to put a delay or repeated activations. Though I'm pretty sure such features would jack up the price considerably, so I can't really fault it for the lack thereof.

Delivery drivers often knock/ring bell and immediately decide no-one is in. This will be useful to detect someone arriving before they arrive. One PIR and two chimes. All needing batteries. But you can also power from USB. As the items are rated for 'indoor use only' I have installed a cover over the top of the PIR to keep rain away and also block sunshine. The chimes are loud enough and there are a few to choose from.
