DESC: The Watchport/P Proximity Sensor is the first Plug-and-Play USB device for proximity monitoring. The Watchport/P detects the presence of objects within a user-selectable range of 0.5 to 1.5 meters (1.64 to 4.9 feet) of the device. Watchport Manager software provides centralized device status and historical data logging, and allows easy integration of multiple Watchport devices without additional software development. The software allows users to receive email, beeper or phone alerts when an event is triggered, making it ideal for remote monitoring.
