TECKNET Door Alarm Sensor, Window Alarms Sensors, 2-in-1 Alarm & Chime, 3-level Volume Control, Door Sensor for Home Security, Wireless Burglar Alarms for House, Shop, Office, Garage (3 PCS)

After noticing damage to my door someone’s done trying to break into my flat last night, I ordered this. Very easy to set up and as it’s adhesive, no damage will be done to the door which is great to know as I rent. You can turn it off which is great so you know you can have full control over when it is on. It’s more than loud enough to alert you and to scare off anyone if they were to break in even on the lowest setting which is what I have mine on in this video. It comes in a pack of 3 which is nice incase one breaks or the adhesive strips lose their stickiness. Whether you’re in a flat like me or a house and want to feel that extra bit of security for whatever reason, these seem like a good and cheap choice.

Brought for my companies new office for the front entrance. Works great with loud tone. Easy installation with the sticky back application, equally easy to remove with a firm pull and reapply. But equally sturdy, staying on in the door in a busy entry way without issue. Have not used the security function but was extremely loud when accidentally switched on. Pack of 3 worked great, cheaper than other options

These are brilliant. Easy to install and gives me peace of mind at night. I've recommended to friends too

These are great door alarms. Easy to fit on normal doors. I had to be a bit inventive on mine getting the sensors to match up due to the door and architrave design but I managed it. Highly recommend them.

These window alarms work well and are very easy to set up. For anyone looking for extra security these are a good buy.

This was recommended to me as well. Easy to install and easy to set. It sticks well and last long time. The volume is high enough to be heard even outside the house. It comes in 3 set, very handy, no need for wifi.

Excellent value. Comes ready to install, no faffing around with apps and batteries. I do recommend planning first how you’re going to place the parts on the window as I ended up having to put my sensor “sideways” rather than using the strip placement intended at the back. Very loud, plenty loud enough to put off any potential burglar.

Great alarms, easy to install and great value for money. Alarm/chime volume is perfect and can be easily adjusted. Forgot I'd put them on the doors last night and nearly deafened myself this morning when trying to leave for work so they definitely work!

Tenía uno de Leroy y este es mejor, te vienen 3 , he probado uno y es una locura, suena súper fuerte aún en el nivel bajo de sonido estoy enamorada por el precio una ganga y tiene botón de apagado para en casa apagar y al salir de viaje por ejemplo encender , encantada, quizás compré de nuevo si me hace falta alguno más.

Abschließen allein reicht ja im Ernstfall nicht. Eine komplexere Lösung, mehr Sicherheit zu erreichen, scheidet bei mir im Mehrfamilienhaus aus. Dieser kleine Türalarm, noch dazu für kleines Geld, ist hier die perfekte Lösung. Gong oder auch Sirene sind in beiden Lautstärken gut zu hören. Die Sirene hat auf jeden Fall eine Abschreckendere Wirkung. Es gibt für alle Türen und Fenster eine Möglichkeit, diesen Sensor zu verwenden, wenn man bei der Anbringung etwas mitdenkt.

Producto bastante bueno, facilísimo de instalar y con un funcionamiento bastante bueno, buen sonido

Finora i tre allarmi funzionano perfettamente. Il suono è potente anzi potentissimo, anche il più basso volume. Li ho posizionati sulla porta d'ingresso e sulle porte di due armadi differenti. Un allarme l'ho dovuto capovolgere a causa del tipo della porta diversa nell'interno. Seguendo le istruzioni è facilissimo da installarli. L'allarme e il magnete devono essere molto ravvicinati: la distanza deve essere di 4-5 mm, altrimenti aprendo la porta non suona. Quindi l'indicazione vaga di installarli entro 2 cm non è sufficiente. Dalla distanza di 9 mm ho dovuto ravvicinarli: la loro distanza è di 4 mm, così funzionano perfettamente. Installati su dislivelli non funzionano se non viene risolta la differenza dell'livello della superficie delle ante. Sono soddisfatta d'aver scelto questo prodotto con poca spesa per il set di 3 allarmi. Spero che questi allarmi durino a lungo. Il prodotto è arrivato subito il giorno successivo di quello dell'ordine effettuato. Grazie.

Perfekt für ein kleines Sicherheitsgefühl im Erdgeschoss. Funktioniert einwandfrei und ist sehr laut
