The GJD D-TECT Laser 5 m x 5 m (GJD505) is a laser-based security detector that creates virtual curtains and surveillance zones using laser scanner time-of-flight measurement. It is programmable to within 10 cm and has two relay outputs. Typical applications include monitoring pedestrian and vehicle access points, perimeter protection, securing open sites and safeguarding works of art.
Key features
