XP21 Stop Bar Detector
The XP21 is a first-of-its-kind stop bar detector capable of detecting traffic in an entire small intersection by itself. Accompanied with an Arc and the Expanse software, you can see and configure all your detection zones from your computer.
Description
The XP21 Stop Bar Detector:
- Uses radar to get the most accurate stop bar data for an entire intersection
- Part of the Expanse system: connect it to an Arc and use the Expanse software to take advantage of all the great features of the system
- Native IP device: put it on your network and use the software to interact with sensors on your system
- Field-replaceable surge card means you can easily replace the surge protection in the field after a surge event
- Employs Wavetronix’ industry leading radar technology for the highest quality high-definition detection
- Features a GPS receiver for georeferencing the sensor
- All-weather, all-condition performance
- Built-in heater prevents snow from blinding the sensor
