Crisma Security, an Italian company that specialises in designing security systems for highly critical sites, announces the integration of Navtech Radar with the Ulisse Thermal Radical range of PTZ thermal cameras made by Videotec.
This combination is for management of large-scale critical infrastructures, the two firms say.
The Navtech Radar is a radar device that uses millimetre waves, as an automated way to help protect against intrusion. The Navtech Radar is able to detect a person in a radius of up to 1000m automatically, it is claimed, by day and at night, and in all weather conditions including rain, fog and snow according to the makers. Each radar sensor performs one 360 degree scan cycle of the monitored area every second. This means that the device is able to map any target objects in the scene that it’s surveilling (such as vehicles, and people), their speed and their direction. The sensors can define several parameters with regards the sub-division of the areas to be monitored, with alarm rules for abnormal situations that are customised according to set criteria.
The radar detection is accompanied by the visual surveillance capability of the Ulisse Thermal Radical, a PTZ thermal camera that offers high functional and mechanical performance and, with a wide field of vision, is capable of capturing images of people and objects even in the dark or during adverse environmental conditions.
The integrated system means that the radar automatically guides the thermal PTZ, and uses software to send the coordinates of the target that needs to be followed rapidly and continuously. This provides real-time visual feedback of the detected event.
The interaction between the radar and the PTZ thermal imaging camera is synchronised. The coordinates given by the radar guide the PTZ, following the target in a sequence. The pan and tilt camera’s autofocus allows the camera to achieve focus levels.
The integrated system brought together by Crisma Security and Videotec has been tested at an Italian airport.
