Review on YoLink Smart Motion Sensors, 1/4 Mile Range Wireless Indoor Motion Detector, Alexa IFTTT Compatible, App Alerts & Remote Monitoring, 2 Pack with YoLink Hub by Roy Bush

I have a hotel that has been closed for almost a year due to Covid. Trying to keep unauthorized people off the hotel premises was a difficult task. The YoLink line of products has been a great tool for my staff to notice when someone enters the premises. I have many motion sensors throughout the house, as well as a few sirens. When the sensor is triggered I look at the notification in the app and then at the camera where the activation happened to see if I have a security issue. Now staff don't have to monitor the cameras - no one can bypass the building without the knowledge of the staff. They are easy to set up and install and I have never had to change the battery in the last 6 months. They work great with YoLink's siren alarm. The range is fantastic with the necessary hub. It was difficult for me to get a good connection at the other end of my building as there is a lot of concrete and steel between me and the farthest sensors. I just added another hub at the other end of the building and the range problem was solved. I've had Wi-Fi sensors that don't compare at all to the YoLink line of sensors. This is an indoor product that I use outdoors (out of weather) so there are a few issues I have to deal with that are not the product's fault. I get a decent amount of false positives due to changing lights, reflections, and shadows. This is a great product!
