Posted .Hi LourdesM.
Thank you for taking the time to share your experience with us. We understand the importance of having all relevant product information prior to purchasing. The features and technology provided by the Ring Ring Alarm Contact Sensor (2nd Gen) are incredibly valuable and help provide you with peace of mind about your home security. We can definitely provide you with more information regarding the concern mentioned in your review.
It seems like there is some confusion regarding the product requirements. The Ring Alarm Contact Sensor (2nd Gen) is designed as part of the Ring Alarm security system and requires either a Ring Alarm Base Station or Ring Alarm Pro to function. This requirement is mentioned on the product page, which notes that Ring Alarm or Ring Alarm Pro is necessary for the Contact Sensor to work. It communicates with the Base Station using Z-Wave technology with a range of approximately 250 feet in open air, line of sight. The Base Station acts as the central hub that receives signals from the Contact Sensor when doors or windows are opened or closed, processes these events, and triggers alerts or alarms based on your system's armed status.
