Hardwired Driveway Entry Alerts

About

Mier Products is a leading manufacturer of hardwired driveway entry alerts. Unlike motion based driveway entry alerts, Mier uses a buried probe near the driveway that detects an interruption of it's magnetic field when a metallic object like a car passes near it. This is much more reliable than motion based / ir type sensors and means no false alerts from animals or blowing leaves and such. Hardwired driveway alerts make for a very reliable option to get notified when a car is going up or down your driveway. While they do tend to be more reliable, it does come at the cost of a more intensive installation process. Mier Products line of driveway alerts is very flexible. They are robust enough to be used for commercial applications, but are also great for residential installations. They can be used as a self-contained system or connected to an alarm system. Mier’s Drive-Alert can be even be used to add some home automation capabilities to your property. The Drive-Alert probes work by detecting distortions in the Earth’s magnetic field that is caused by large metal objects (that contain iron) making them very good at avoiding false alarms. Whether you are a home owner that just wants to know when they have a visitor or a business owner that wants to know when someone pulls into their drive-through or a farmer protecting his valuable equipment or anything in between, the Drive-Alert can provide you all the features you need and more. Because the probe is looking for sudden changes to the magnetic field near it, there are three factors that affect the system’s performance: size, speed, and distance. The probes can detect a larger iron object from further away than a smaller iron object since they will make a larger distortion. Faster moving objects produce more sudden changes than slower moving objects. And the closer a metal object is the easier it is to detect. A truck that is going 65 miles per hour can be detected up to 50 feet away. A car moving slowly down a drivewa
