Mengshen Wireless Door and Window Alarm, 105dB Motion Sensor with Remote Control, Battery Powered, 15m Range, 2 Pack (Includes 2 Alarm and 1 Remote Control)

The product is completely amazing and it took only 5 to 10 minutes to fix. You can fix it in any surface by means of double side tape. Previous I thought it Contains both vibration and magnetic sensors but it contains only magnetic sensor. During the time of checking the products itself I got a little bit of ear pain and the sound is awesome and it's having 108 decibel. Normal human should hear only less than 85db. Surely it'll make fear to third or mischief. Even unarm the siron we'll have some beep sound and I liked it the most. Overall it is the best.

I would have given 5 stars ... 1 star less only because its made in china... else product is good sound is really loud for its small size. Go for it ... why cant we make such products in India

Easy to Install, Works like central locking, Alarm Volume is also very good and two modes (Alarm or Bell) with remote control.

Product working as described. All items received as mentioned. Remote has good range,siren volume is loud enough. Good purchase,solved my purpose. 5 star from me.

Noise level is less may be approx 88 db while 105 dB is mentioned in description and batteries not included in package. It is very easy to remove for and will not serve purpose of high noise alarm.

Getting hang, not reliable, In starting work fine as expected but after two days started getting hang and producing, weared sound. Not able to return as i have thrown the box.

Items aren't waterproof. We can't install outdoors...Better to improve!!! For indoors, product is suitable and great.

Product is good, but the sound is a bit less compared to other products available at Amazon.

Soluzione pratica ed economica come antifurto per casa senza fili. Questi piccoli antifurti vengono applicati nei due battenti di porte o finestre, cin modi che quando vengono allontanati a causa dell’apertura della finestra o della porta, interrompono il campo magnetico creato. L’attrazione tra le due lamelle è tale da creare un campo magnetico che, al momento dell’apertura di porte e finestre, viene interrotto in un cortocircuito. Sarà questo a determinare l’allarme. Il loro compito, una volta rilevata l’apertura, sarà quello di inviare un segnale sonoro molto forte, che lo si attiva e disabilita con il telecomando. Si applicano con degli adesivi che escono nella confezione (vedere foto) molto forti, quindi non dovrete utilizzare colla o fare buchi. A livello estetico sono minimal e non invasivi, mimetizzandosi bene una volta applicati. Non necessitano di collegamento alla rete elettrica in quanto utilizzano batterie alcaline di tipo AAA. Ovviamente non sono da intendere come un antifurto definitivo ma io l'ho scelto come una opzione aggiuntiva altre a telecamere e antifurti già installati. Efficaci e importanti nel sistema di allarme per rilevare le intrusioni, i contatti magnetici per antifurto sono anche economici. Nella componentistica dei sistemi di allarme per al casa o l’ufficio, i contatti costano poco, ne servono solamente un paio. Consigliati.

Gute Qualität zum günstigen Preis. Macht was es soll...die Alarmgeräte werden mit AAA-Batterien betrieben - die Fernbedienung mit 12V 27A wie früher bei Kameras. Wenn ein Alarm auslöst wird der zweite Alarm auch ausgelöst und es gibt so richtig Radau...so muss es sein ...so ist es gut. Habe die beiliegende Batterien AAA durch Lithium ersetzt, weil keine Lust habe alle 3 Monate die Batterien zu kontrollieren und Lithium läuft eben auch nicht aus....bei der Fernbedienung habe ich mir eine entsprechende Dura Cell gekauft...sind alle alkalisch mit einer Lagerfähigkeit von 3 Jahren. Die Batterie wird nur belastet wenn ich die Alarmgeräte aktiviere oder deaktiviere, somit hält die Batterie ewig. 12V 27A in Lithium ist leider nicht zu bekommen. ganz klare Kaufempfehlung für Indoor wie auch Outdoor hier in einem regengeschützten Bereich ist logisch.....

Productazo! Práctico, sencillo y funcional.

As you can see in the picture , I put it up high at the top of the door. Well at least children can't reach it. But anyway, I live in a high rise apartment building. Alot of traffic walking back and forth all the time. Wanted something that I can activate when I'm out. Wanted something to activate especially when I'm in bed sleeping. If someone picks the lock and that door opens, it immediately triggers a super loud alarm! I'm confident it will scare away intruders. Scared the crap out of me when i first triggered it by mistake! I think I paid 9 bucks. It comes with the remote control fob. I don't have small children anymore but I would recommend this item to family's. It was really easy to stick to the door. Comes with a couple strips of double faced tape. It'll take you 5 minutes to set up. Anyway, it's perfect for me. Just a little bit of peace of mind I guess.

Ich benutze die Alarmanlage zur Überwachung einer Haustür. Das zuerst notwendige Pairing (Remote Control mit Alarmanlage) wird beiliegend gut erklärt. Der Alarm ist sehr laut und abschreckend. Wenn die Tür oder das Fenster nach Auslösung des Alarms wieder geschlossen wird, bleibt der Alarm an und kann erst wieder mit der FB ausgeschaltet werden, also genügend Reaktionszeit. Scharf- und Unscharf- Schalten ist mit der FB anhand akustischer Rückmeldungen ganz einfach. Das Preis- Leistungs- Verhältnis ist sehr gut. Ich würde es jederzeit wieder kaufen, zumal auch der Support exzellent ist.
