Ring Motion Detector
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love the Ring Security System! I have a motion sensor on my main level and lower level walk out. You can set them separately so when I’m home the lower level is protected and when I’m away both are set to on.

Posted .Hi Juan.
Thank you for taking the time to share your experience with us. We understand how important it is for your Ring Ring Alarm Contact Sensor (2nd Gen) to function consistently and reliably, so you can effectively monitor your home. 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 want to ensure your device is working as intended by providing you with solutions to resolve the concern you mentioned in your review.
It sounds like the device is not performing as expected. There are some troubleshooting steps that you can take if your Ring Alarm Contact Sensor (2nd Gen) is disconnecting easily when opening and closing windows and doors:
1. Check the positioning of the sensor and magnet - they should be properly aligned and no more than 1 inch apart when in the "closed" position.
2. Move the Contact Sensor closer to the Ring Alarm Base Station to improve connectivity.
3. Add a Range Extender between the Contact Sensor and Base Station to improve signal strength and range.
4. Test the connection by pressing the button on the front of the device: - Three green blinks means it's ready to connect to the Base Station - Single green blink means it's connected and communicating properly - Single red blink indicates it cannot communicate with the Base Station
5. Check the battery power - cold temperatures may drain batteries faster. The sensor uses two CR2032 batteries which should last up to 3 years depending on usage.
If the above steps do not resolve the issue, we recommend to perform a factory reset on the device. You can reset your Contact Sensor by following these steps:
* Slide to remove the Contact Sensor from its base.
* Use a pin or paperclip to press and hold the pinhole reset button on the back. After the LED light turns off, release the reset button.
For more information on your Ring Ring Alarm Contact Sensor (2nd Gen), we invite you to reach out to our community. Ring Community is our first peer-to-peer community forum, giving our customers the ability to help one another and share their personal feedback and experiences with Ring. We look forward to hearing from you if we can be of any further assistance!

Contact Sensors
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I thought I had the Ring products I needed in order for these contact sensors to be installed. However, when Total Tech came to my house to install them, we discovered that I need to purchase a hub. Looking into buying this device when Black Friday rolls around, and hopefully it won't be too expensive.

The Ring Alarm Contact Sensor needs to connect to a Ring Alarm Base Station or Ring Alarm Pro to function.The Ring Alarm Base Station serves as the central communication hub connecting sensors to the Ring app. It also triggers alarms and sends notifications to your phone when sensors are activated, and it acts as the control center for arming/disarming the system, adjusting settings, and managing the overall Ring Alarm system.

Please increase detection range
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The motion detection is not very long range. Will only detect maybe 7 ft radius if that. So you have to be crafty in where you install this unit. Despite the above mention the overall new ring units + cameras works really well together. I feel it’s all synchronized to help protect and secure your home or business.

Good product
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Works well. Bought this to add additional sensors that didn't come with the ring home alarm system. The only issue is the 1 door sensor goes offline for some reason but that came with the home alarm system.
