Why do smoke detector alarms go off even when there's no smoke? The most likely reason smoke detectors go off unexpectedly is that people aren't changing the batteries in them often enough. In most sensors you might think of, the strength of the signal goes up when they detect what they...
If you love the smell of scented candles or incense sticks, you may be concerned about the potential for setting off the smoke detector. ...Non-smokingcollege dorm rooms also tend to have hyper-sensitive smoke alarms, which could be triggered by burning incense or blowing out a candle. Can...
Yet, the reason might lie not in a real threat but in common household triggers. Let’s dive into what could be causing your smoke alarm’s false alarms and how to fix them. Smoke alarms are essential for home safety, tirelessly standing guard to alert you at the first hint of a fir...

(2024). Sensor-based systems, while offering automated surveillance, are prone to false alarms from non-fire sources like dust or fog and require proximity to the fire Wang et al. (2020b), often resulting in late detections. Satellite imaging provides a broader coverage but is limited by ...
- Feature enhancement: The status bar is now visible from all tabs - Features added: The status bar is now used to also show some important events, in addition to chat room counts and news alerts...the new events show are: Buddy on/off, Buddy away/back, PM 'buzzes' and mail alerts...
Priorities include quick time-to-detection, high recall to avoid missing potential fires, high precision to avoid frequent alarms that undermine trust in the system [2], and efficient performance to operate in real time on edge devices. However, the task proves challenging in real-world scenarios...
Their result showed a dramatic decrease of false alarms in different forest fire scenarios [10]. Another work [16] used Faster R-CNN with feature pyramid networks [39] and RetinaNet [41] to detect small distant wildfire smoke in an average of 6.3 min from the first observation of the fire...
