What is a "Audio Video Detector"? The Most Authoritative Explanation.
How does audio detection work?
In the first instance, audio detection generally senses changes in typical ambient sound levels, such as sudden increases in volume. These can work well within certain environments. For example, an office which handles customers or clients may generally have a low level of ambient noise.Is audio detection the future of surveillance?
Audio detection and the classification of sounds have become realistic and affordable options in surveillance applications. The technology has been driven by advances in specific audio-based analytics algorithms, coupled with the shift to GPU-based hardware.What is volume-based sound detection?
Volume-based systems are simply looking for a spike in sound intensity rather than a specific type of noise. In the case of sound classification, a more complex and accurate layer of analytics is added. It is still possible to trigger an event following unexpected noises and volume increases, but these can be filtered by the type of sound.Does your site need basic audio detection or sound classification?
While some audio detection options have specialist applications, such as gun shot detection, others enable a wide range of sounds to be used as full or partial triggers for both alarms and automation. The challenge is determining whether a site requires basic audio detection or sound classification, as the two are very different.Related Articles
