Review: I fit this motion alarm for the entrance door at our house. 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 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

Questo particolare sensore di movimento (PIR) è frutto di un'idea geniale, ad ogni rilievo di movimento riproduce un file mp3. Ha molteplici campi di applicazione, è utile sia in ambito domestico che lavorativo. Può essere usato come allarme per segnalare un accesso non autorizzato in un'area privata; come campanello automatico all'ingresso di un ufficio; come jingle player per pubblicizzare un prodotto in un negozio, per accogliere ospiti in casa con una musichetta di benvenuto e per la mia gioia, può essere usato come repellente per animali randagi. IL MIO VOTO COMPLESSIVO: 7/10. CONTENUTO DELLA CONFEZIONE: - sensore PIR alimentato con batteria ricaricabile integrata; - caricatore per rete elettrica; - cavetto lungo USB/Micro USB per la ricarica; - memory card trans flash da 128 Mb. - supporto snodato per installazione a parete. ESTETICA DEL PRODOTTO E MATERIALI: Il dispositivo è realizzato in plastica, è ben rifinito ed è molto solido. Non è adatto per installazioni all'aperto, non è progettato per essere esposto alle intemperie. FUNZIONAMENTO: Per prima cosa bisogna caricare dei file mp3 sulla memory card in dotazione. Online ci sono tanti siti che offrono suoni, effetti speciali e jingle in formato mp3 gratis. Dopo aver inserito la memory card nello slot dedicato sul dispositivo, regoliamo il volume al 50% ed accendiamo il sensore. In automatico sarà eseguito il primo file audio e il sensore rimarrà attivo in attesa di rilevare un movimento. Sul frontale del sensore sono presenti due tasti (A e B) che consentono di selezionare il modo di esecuzione dell'audio. Premendo a lungo il tasto "A" il sensore riproduce ad ogni attivazione un suono dalla playlist, a fine playlist riparte da capo. Facendo una lunga pressione sul tasto "B" si passa alla riproduzione sistematica di un solo file, per selezionare il file da eseguire basta premere tante volte su "B" finché quello di nostro gradimento viene riprodotto. Premendo contemporaneamente “A” e “B”, si attiverà la riproduzione casuale dei file. Sul laterale sinistro del sensore, oltre allo slot della memory card e il connettore microusb è presente un connettore Jack femmina che consente di collegare un impianto audio di amplificazione. PECULIARITÀ: - alimentazione con batteria ricaricabile integrata di lunga durata (difficile stabilire l'autonomia, perché è in funzione del numero di attivazioni giornaliere); - ingombro ridotto; - installazione facile e veloce, non bisogna predisporre cavi e grazie al sistema di fissaggio speciale, il sensore può essere velocemente sganciato dalla parete per essere ricaricato. - il volume ha una discreta potenza e la possibilità di collegarci una cassa ausiliare è un punto di forza. CRITICITÀ/DIFETTI: - Manuale d'uso minimalista e non in italiano, si incontra qualche difficoltà inizialmente per capire come funziona il tutto, ho dovuto fare delle ricerche online per capire come usarlo. - è un peccato che non sia adatto per l’esterno; - la scheda tecnica lascia intendere che si possa registrare audio direttamente dal dispositivo, ma non c’è stato modo di capire come farlo. Ho il dubbio che ci sia stato un errore nella descrizione delle funzioni. RAPPORTO QUALITÀ/PREZZO: Il costo di questo dispositivo è importante, ma correttamente rapportato alle peculiarità del prodotto.
