We have lots of deliveries coming in nearly every day and I wanted this device for greetings and giving instructions to the drivers. The best feature for me in this device is the ability to record my own message or messages. I can customise my message based on the circumstances. The sound is loud and clear and the voice alarm turns on every time without fault or delay. The volume is adjustable i don't have it set to the max as our street is not very noisy. I have it installed just above the door in the covered porch so it is protected from rain. The fitting was included as well as quite a long USB cable which I have permanently connected through the small hole I drilled in the frame. We already had some positive comments from our postman. Can't wait for Halloween and Christmas for some fun customised messages. I'm very happy with this motion alarm. Review: Funciona muy bien - Funciona muy bien y estupenda calidad. Como mejoras, me hubiera gustado que el soporte estuviera abajo y no atrás. El altavoz de 2 w es suficiente, aunque suena a lo que es ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JR5LQRQ | | Antenna Location | Indoor | | Battery Description | Lithium | | Brand | Waytronic | | Customer Reviews | 3.6 out of 5 stars 127 Reviews | | Manufacturer | Waytronic | | Maximum Range | 4 metres | | Mfr Part Number | Smartsound V2 | | Model Number | WT-S11 | | Number of Batteries | 1 Lithium Polymer batteries required.

Como mejoras, me hubiera gustado que el soporte estuviera abajo y no atrás. El altavoz de 2 w es suficiente, aunque suena a lo que es ### ⭐⭐⭐⭐⭐ Excellent product *by B***T on 13 March 2026* Excellent product. I needed a product that could take a recording but also be able to be turned on and off on a timer. There is a microSD card that is removable and will allow you to place recorded audio files from your computer onto it (make sure you format the SD card first). I carefully took the cover off and unplugged the lithium battery so that the unit was only powered through the supplied USB cable, then connected to an Alexa outlet so that it would only trigger on motion since at certain times of the day. Volume is pretty good too. ## Frequently Bought Together - Lithium Battery Powered PIR Infrared Human Body Detector Motion Activated Sound Player Loudspeaker Voice Reminder with 128M SD Card for Sales advertising Door Greeter Welcome Alarm Entry Alert - Amazon Basics 12-Pack AAA Alkaline High-Performance Batteries, 1.5 Volt, 10-Year Shelf Life - Amazon Basics 48 Pack AA High-Performance Alkaline Batteries, 10-Year Shelf Life, Easy to Open Value Pack --- ## 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.pt/products/560212367-lithium-battery-powered-pir-infrared-human-body-detector-motion-activated](https://www.desertcart.pt/products/560212367-lithium-battery-powered-pir-infrared-human-body-detector-motion-activated) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-11-14*
