J'ai acheté ce capteur en complément pour améliorer la sécurité de ma maison, et je suis très satisfait. L'installation est très simple, il suffit de fixer les capteurs sur la porte ou la fenêtre et tout fonctionne parfaitement. Le système 433 MHz assure une connexion stable avec mon alarme. Le bouton d'urgence est un plus en cas de besoin, et l'interrupteur d'alimentation permet de l'éteindre facilement si nécessaire. Très réactif et efficace, ce capteur est un excellent ajout à mon système de sécurité. Je recommande vivement.

Es compatible con muchas estaciones de alarma. Pero recomiendo ver las indicaciones del fabricante. A mi me están funcionado bien para una eray 3000.
