Application notes
Thermal camera cores for reconnaissance robots Customer Success Story - XTM thermal OEM core installed on reconnaissance robot
Dual-Band Monitoring Keeps Trains Running in Winter Keeping critical parts of the railroad infrastructure free of snow, sleet, hail and ice – and even detecting unauthorized persons walking the rails – is essential for a safe and uninterrupted transportation service. Dual-band monitoring of critical rail elements with a PTZ (pan, tilt and zoom) camera platform in the visible and thermal infrared ranges can remotely inspect installed switch heaters at a range of up to 2000 ft.
