Nando autonomous drone -based platform turns the archaic model of site security upside down. Instead of guards making the rounds and patrolling a perimeter to detect intrusions into the secured site, with a response team on call , our eye in the sky hovers above your site for up to 70 minutes at a time, capable of detecting both movement and the human form at a range of up to 250 meters. Given the superior field of vision of a drone together with exceptional flight time means that a single eye in the sky is capable of replacing perimeter patrol – and for a fraction of the cost.
