Some even have IR beams for safety.[MEDIA=youtube]r4GFNGvZ8sg[/MEDIA]IF you do go with loops and loop detectors, please remember to twist the leads back to the loop detector before burial to null the signal from the loop to the detector.  Some have magnetic vehicle sensors you bury close to the driveway if you don't want to hassle with loops.[URL unfurl="true"]https://allsecurityequipment.com/products/linear-fm139?currency=USD&variant=38006121103533&utm_medium=cpc&utm_source=google&utm_campaign=Google%20Shopping&stkn=040f6b0fac7e&gclid=CjwKCAjwu4WoBhBkEiwAojNdXprHs1Hi9PrrBzdbxvN2_uvtfVBXim_RDHIxVns_GvybvWiPbJQtyBoCZDMQAvD_BwE[/URL]At the airports, I had to configure gates to open only about 3 feet upon card read for pedestrians unless there was a vehicle present then it would open completely.  Just some of the stuff I used to do.  It was kinda of fun having to configure stuff like that.</blockquote>
