Piggybacking is a real threat in todays world
because most doors or access control systems
cannot prevent it from happening proactively.
They can sound an alarm or record the event,
but it is up to the security staff to respond
quickly. StereoVision has been proven through
rigorous testing to be extremely accurate, and
when paired with a security revolving door or
portal and access control system, can
prevent unauthorised entry without the need
for manned supervision. The technology is available as a Level Up in security option on our Circlelock Combi or Solo portals, and our Tourlock 180 security revolving door. StereoVision combines optical and near-infrared sensor technologies for an exceptionally reliable solution that is not impaired by lighting or reflections.
