Video-based fire detection

　　A new version of Bosch Building Technologies' video-based fire detection system AVIOTEC IP starlight 8000 now enables the early detection of fires with cameras even in low light, the manufacturer says.

　　Flames and smoke are detected down to an ambient lighting level of 2 lux, Bosch says. For this purpose, the firm has extended its video analytics in the camera by artificial intelligence, which processes the results of more than 20 algorithms and makes an alarm decision on this basis. This leads the developer says to improved sensitivity without compromising against false alarms.

　　With the new firmware version 7.61, AVIOTEC IP starlight 8000 is suitable it抯 claimed for application in areas with very low light such as warehouses and production plants at night. In case of changing site conditions, the sensitivity can be adapted by using programmable schedules. Thus, for example, it is possible to optimise robustness against false alarms during busy daytime operation; while deserted buildings, where quickest detection is required, can use the high sensitivity at night.

　　Since the new solution also works with minimal ambient light, it saves on planning, installation and operation of the lighting, the makers say. Also reduced are the risks for applications with high fire load in low light; for example, multi-storey car parks where risk is typically quite high. Here AVIOTEC IP starlight 8000 offers detection to protect vehicles and electrical charging stations. In historic buildings, the solution can now also be installed in little used side rooms with minimal lighting, for example through tiny windows. The installed cameras can be used at the same time for fire detection and video surveillance.

　　The video-based fire detection AVIOTEC IP starlight 8000 comes with the new firmware. Existing installations can be upgraded by a free firmware update. 

　　

　　基于视频的火灾探测

　　新版的Bosch建筑技术的基于视频的火灾探测系统的AVIOTEC IP starlight 8000摄像机现在即使在弱光环境下也可以对火情进行早期探测。

　　Bosch表示，在低至2 lux的环境照明水平下该摄像机都可以检测到火焰和烟雾。为此，该公司通过人工智能扩展了其在摄像机中的视频分析功能，该功能可处理20多种算法的结果并在此基础上做出警报决策，且在不影响误报的情况下还提高了其灵敏度。

　　凭借新的固件版本7.61，AVIOTEC IP starlight 8000可适用于光线非常暗的区域（例如晚上的仓库和生产工厂）中使用的产品。在现场条件不断变化的情况下，也可以通过使用可编程时间表来调整灵敏度。因此，例如，可以优化在繁忙的白天操作期间针对虚假警报的鲁棒性；而摄像机在需要快速检测的空旷建筑物中使用时，则可以开启高灵敏度功能。

　　制造商表示，由于新解决方案还可以在最低的环境光下工作，因此可以节省照明的规划，安装和操作。在低光照条件下高火灾负荷应用的风险也得到了降低。例如，通常风险很高的多层停车场。AVIOTEC IP starlight 8000在此处提供检测功能，以保护车辆和充电站。现在，在历史悠久的建筑中，该解决方案也可以安装在很少使用的侧室中，并且只需很低的照明，例如通过小窗户的光线。因而，这款摄像机可以同时用于火灾探测和视频监控。
