A great many companies keep major assets outside ... out in the field. Equipment can be stolen, vandalised or just be in the wrong place. Tracking, monitoring and protecting all the equipment used outdoors is manpower intensive, time-consuming, complex and expensive. Portable, battery-powered GPS trackers are prohibitively expensive because sooner or later, their batteries need to be manually recharged. Passive Eye has developed and patented, a self-sustaining, energy harvesting and power management technology for our tag used to track, monitor and protect land and marine-based assets companies use or keep outdoors. Our USP is that it NEVER needs manual battery recharging. Check out our website (passive-eye.com) and feel free to contact us for further information.
