Style: 1-Pack Contact Sensor
Ring products are absolutely phenomenal. Their contact sensors and all their products work amazingly well, and are extremely easy to install. I highly recommend the entire Ring security system!

Style: 1-Pack Contact Sensor
The Ring Alarm Contact Sensor (2nd Gen) is an excellent addition to my home security setup! Installation was a breezeโI simply attached the sensors to my doors and windows, and they immediately synced with my Ring Alarm system. The setup process was simple, and the app made it incredibly easy to monitor and control. What I really love about these sensors is how responsive they are. I get instant notifications on my phone if a door or window is opened, which is exactly what I need to stay alert when I'm not home. The sensors are small, discreet, and blend in well with my homeโs decor without drawing too much attention. The battery life has been great so far, and I appreciate that theyโre designed to last. I also feel more secure knowing I can integrate the sensors with my entire Ring system, giving me full control over my homeโs security. Whether Iโm inside or away from home, I always know when the system is triggered. If you're looking for an easy-to-use, effective contact sensor for your Ring system, I highly recommend the Ring Alarm Contact Sensor (2nd Gen). Itโs a great way to enhance your home security.

Style: 2-Pack Contact Sensor
Z-wave is wonderfully reliable, having a base station and an extender ensures that all instances of change are tracked, even if the Wi-Fi goes down, and that the base alarm will activate with or without it. Z-wave is why I go with Ring for my exterior alarming, rather than Wi-Fi. Zigbee would probably work plenty well enough, when I can eventually figure out how to set up an MQTT server to take it offline and self-reliant, but the Ring station is prebuilt and already accomplishes the task out-of-the-box, so yay. Of course, still need Wi-Fi to check the logs, but arming/disarming can be done from the keypad even without Wi-Fi, and if Wi-Fi's online, it can be done from the phone app. Robust and convenient. The developer's mindfulness to allow for backwards-compatibility with prior versions is commendable, too. I like complicated setups, but I like simple setups, too.

I set up my home security system about 4 years ago (2020) using Ring. The sensors at the time were Gen1. They were pretty large and don't particularly blend in due to their size. The new gen 2 sensors are half the size. Setting up was quick and easy. Open the app, select add new device, then follow the prompts. You don't need to type anything in, unless you want a custom name for the device. Just click a button to confirm the action you are being directed to take, such as scanning the QR code for setup. You don't need to open another app, just click the button to scan the code and your camera opens. The QR code is provided on the device and on a separate slip of paper for convenience. Complete the prompts and the device is ready to put in place. The sensor has double sided tape. Just peel off the backing and stick in place. If you need a more permanent mounting (which I have never needed, even with the gen1 devices which are much larger), the back panel pops off and there are screw holes. Easy peasy.
