eufy Motion Sensor White-T8910021

Review: El sensor se puede integrar fácilmente en los productos de seguridad Eufy y funciona tal y como se anuncia. Hay instrucciones claras sobre cómo y dónde colocar el producto. La batería dura aproximadamente dos años. Eso es algo que tendré que comprobar. El sensor se puede montar con tornillos o con cinta adhesiva de doble cara.
Review: Very good
