I’ve set up a new ST integration with my Hikvision NVR. I have some IP cameras that have a feature that detects an object crossing a virtual line. I’ve created a driveway entry line and configured the NVR to close one of its dry contact closures when something crosses this line. This gives me a virtual driveway entrance event. I connected an ecolink contact sensor (which has dry contact inputs) to the NVR closure output, and linked the sensor to ST. I’m now using notify me when to send a push notification when someone enters the driveway, and Smart Lighting to turn on some floodlights when someone enters the driveway at night after I’ve gone to sleep.
Hope this gets the wheels turning for anyone else with these NVRs!
