Wireless Train Track and Zone Sensing
No need to wire sensors under the track. Just let your webcam watch for the trains.
I'm NOT doing it anymore!
Everytime I change my layout, I have to change the sensors under the track to perform automated functions. Well Not anymore. I found a program called Webcam Zone Trigger that solves the problem. I can simply place a web camera above the layout and easily place adjustable zones that are actuated when the train motion is sensed. The number of possible zone actions is impressive.
I have tried 10 zones and haven't found the limit yet.
I tried the free trial version and then spent the $45.00 to get the standard version with some great options. If I ever need to use more than one camera, I will simply go pro for $96.00. I save more than that in circuitry and time with the old system of magnets and sensors. What could be easier than an app for that.
My first test is with my n-scale layout to play different sounds in different locations. By using two zones next to each other you can easily sense the speed, direction, or length of the train.
Sensing zones to detect train position and sound whistle and bells. Each zone has a different response.
Webcam Zone Trigger has a good selection of responses to motion detection at each zone, including sound and signal to port or device.
The blue color in the zone indicates motion detection.
