In this paper we given an overview of the design and predicted performance of a passive video-rate THz camera intended for stand-off and walk-by concealed weapons and explosives detection. The system is based on previously reported work, and it utilizes a linear array of superconducting antenna-coupled microbolometers. Our present efforts have focussed on improving the performance, stability, set-up time and cost of production of the camera. The system is designed to acquire near video frame rate (~10 Hz) passive THz imagery of objects at ~5 meters from the system, with a field-of-view of 2 m x 1 m and a spatial resolution of 1 cm. The system will be readily integrated to other security systems as it provides encrypted stream of THz imagery over conventional LAN interface that also allows for remote operation.
