The DINION IP thermal 9000 RM camera kit from Bosch is a system for contactless measurement of surface temperature at short range in indoor application scenarios. The total system includes a microbolometer-based DINION thermal camera (NBT-9000-F19QSM), a temperature reference device (IBB-5000-35), a VIDEOJET decoder 7000 (VJD-7513) with embedded thermal analytics, and a keyboard (KBD-UXF) for ease of use.
The system combines the capabilities of the camera to detect thermal temperature with the software algorithm, from Bosch, for temperature detection. The algorithm is embedded in the decoder. Quick, on-site calibration and temperature threshold setup enables the system for alarming in cases where human skin is warmer than the configured threshold.
The system derives its alarm threshold automatically from the histogram of cached temperature data, and will then update the new threshold in order to mitigate the environmental influences. The analytics combine face detection and tracing with a multi-point temperature measurement, which allows to detect the most hottest attainable temperature of a tracked person.
The system includes a temperature reference device (blackbody) that generates a stable temperature for the thermal camera to use as a reference. The camera then uses the data to compensate for possible temperature drift. Different regions have different privacy requirements. To comply with these requirements, and to respect the privacy of the people being scanned, users can select the suitable mode where face temperature and absolute temperature information can be hidden, without reducing either the system accuracy or its effectiveness.
The system has the necessary features and functions for users to create either a stand-alone temperature measurement system or an integrated system with multiple cameras.
Stand-alone system
The total system is designed with ease of use in mind. The camera is pre-configured for indoor operation, and has an intuitive user interface via the decoder system for local control and monitoring. Operators can access information such as temperature alarms, temperature histograms, quick video replay, and threshold configuration with a USB keyboard, without the need for an additional computer or software.
Integrated System
The system supports the following operation modes: A. One Camera to One decoder system This mode is most suitable for sites where a standalone system for spot monitoring is desired. The camera can be interfaced directly to the VIDEOJET decoder 7000 for local single camera display on a monitor. A maximum of two monitors can be connected to a single decoder for spot monitoring of any user-selected camera. The operator can use the keyboard interface to view local playback from decoder memory and temperature alarm.
B. Multi-camera to one decoder This mode is suitable for buildings where multiple cameras are required and need to be monitored from one monitoring station (for example, dual entry at the building entrance). A maximum of two monitors can be connected to a single decoder for spot monitoring of any user-selected camera or for simultaneous viewing of all associated cameras. The operator can use the keyboard interface to switch between the cameras or select different views, playback from decoder memory and temperature alarm.
C. Multi-camera system distributed system This mode is suitable for buildings where multiple cameras are required and need to be monitored from multiple stations. The system can be installed using the IP infrastructure, and cameras can be analyzed and displayed using multiple VIDEOJET decoder 7000 units. For long-term storage of video and metadata information, users can add DIVAR IP 5000 series of Bosch recorders to the system.
