Proximity Sensors and Camera Triggers

Well, it is time for RING to make metal sensors that can be placed along people driveways so when a car, bike, bicycle, etc pass by they will trigger any camera/s of choice. As it is now the camera at the end of the 300 foot driveway has a 62 but it will not pick up a car going thru the zone no matter what time of the day it is. This is extremely sad and makes the early warning aspect of these cameras a joke and worthless. We need positive triggers that can sense coins in ones pocket, their watch, guns, cars, motorcycles or as far as I’m concerned the filling in their teeth to start the recordings and to capture the invaders / trespassers. It is my hope you will make such a device very soon and make it battery, solar or 115 VAC
