The photos on Amazon show the transmitter in various locations including a sheltered outdoor location but the instruction sheet clearly states that the device is for indoor use only.I’ve set the device up in doorbell mode and the signal range is excellent and there have been no false alarms so far. There are a wide range of tones and around 35 melodies but the simple ding-dong and very bright flashing LED light is the best option in my opinion.There are a small number of videos on YouTube that demonstrate the device setup and melodies so it may be worth checking them out before purchase saving you some time and inconvenience of returning the product if unsuitable.Purchased from Lanke Direct vía Amazon with free shipping.Recommended. ### ⭐⭐ Almost a good device, but in reality RUBBISH *by M***N on Reviewed in the United Kingdom on 12 December 2021* Has worked for about 2 months, now it only chimes when turned on, the mode button is no longer working and intruder alarm chimes also not working, a little disappointed that the product is not really long lasting or reliable. Have let the seller a message asking for a replacement unit under the warranty, will update if one arrives. But don’t hold your breath.SELLER UPDATE. I GOT A MESSAGE FROM THE SELLER ASKING ME TO CHANGE THE BATTERIES EVEN THE EXISTING ONE WERE NEW, SO I DID WITH MORE NEW BATTERIES, THE UNIT DEVICE IS TOTALLY DYSFUCTIONAL. DO NOT BUY. SORRY BUT CANNOT BE POSITIVE ABOUT JUNK. ### ⭐⭐⭐⭐⭐ Una alarma de calidad para detectar movimiento. *by A***O on Reviewed in Spain on 19 March 2019* Hola. Compré esta alarma con sensor de movimiento para controlar por las noches cuándo se levantaba un familiar con demencia senil. Como muchos enfermos de demencia, se levantaba a altas horas de la madrugada sin orientación y sin saber a dónde ir. Por ello, saber cuándo se levantaba mientras nosotros dormíamos era de crucial importancia.Esta alarma fue de las pocas ayudas que encontré para dicho cometido. Colocando el sensor de movimiento en una pared estratégica, nada más detectar su brazo en movimiento -destapando la cama- hacía sonar la alarma. Nunca falló, pues tiene buena sensibilidad si se sabe colocar y orientar bien.En cuanto a la alarma en sí, es de lo más completo del mercado: diferentes sonidos, diferentes melodías -incluidas varias locuciones en chino- y opción para que únicamente se ilumine el LED, sin sonido. Porque además de altavoz, esta alarma lleva un LED blanco y de varios colores .En cuanto al sonido de la alarma, sí, es fuerte. Nosotros lo poníamos al mínimo y aún así en medio de la madrugada sonaba bastante fuerte, por eso dejábamos la locución en chino: al ser una voz, no se oye tanto como una mediodía.El conjunto se empareja rápida y fácilmente. En nuestro caso, con paredes muy finas y una distancia no mayor a 20 metros no tuvimos ningún problema, pero quizás si la distancia es mayor o las paredes muy gruesas esto pueda cambiar. No lo sé.Si necesitas una alarma para vigilar el movimiento de una persona mayor por la noche, de un niño en su cuna, o para saber si entra alguien por la puerta, esta para el precio que tiene esta muy muy bien, se nota calidad y funciona de manera efectiva. ## Frequently Bought Together - Mengshen Motion Sensor Alarm, Wireless Doorbell Alert for Front Door/Door Entry/Driveway/Mailbox, Home Security System Kit with 1 Sensor and 2 Receiver - YBQ041 - Driveway Alarm- 1/2 Mile Long Range Wireless Driveway Alarm Outdoor Weather Resistant Motion Sensor&Detector-DIY Security Alert-Monitor&Protect Outdoor/Indoor Property - 1 Receiver and 2 Sensors - Blink Outdoor 4 (newest model), Wireless smart security camera, two-year battery, 1080p HD day and infrared night live view, two-way talk – 2 camera system --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/257529198-mengshen-motion-sensor-alarm-wireless-doorbell-alert-for-front-door](https://www.desertcart.vu/products/257529198-mengshen-motion-sensor-alarm-wireless-doorbell-alert-for-front-door) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
