Due to the traditional video surveillance system, limited by the camera lens and installation angle, it is difficult to achieve no dead angle coverage in the surveillance area. Even if the camera is installed by multiple angles, full coverage cannot be guaranteed, because camera image acquisition is subject to many environmental factors (eg, on-site illumination). , strong light source interference, etc.) can not effectively collect the live image. The audio monitoring technology, due to the technical characteristics of the audio itself, basically does not have a monitoring dead angle, and can more effectively control the real-time situation on the scene. Therefore, audio monitoring technology can better compensate for the shortcomings of video surveillance technology.
At the same time, the sound has a series of unique features, such as not affected by day and night, not easy to block, directional and so on. The pickup is placed on the dome to position the direction of the sound, and when the abnormal sound is detected, the dome is controlled to the corresponding position, so that the real-time video of the position where the abnormal sound is located can be seen to a certain extent at a certain time. A variety of information is provided for determining the state of affairs.
In the era of artificial intelligence, voice technology and applications related to voice technology, image technology and related applications have become particularly important today. The data generated by voice, image and other sensors, as well as the production, analysis, organization and consumption of these data, are destined to become the most important development direction in the field of intelligence for a long time. We expect smart audio to bring great changes to security.
Fire Hydrant
Fire hydrant is a device that provides a water supply for firefighters to use in extinguishing fires. It is typically a metal pipe with a valve and a connection point for a fire hose. Fire hydrants are usually located along streets and are connected to an underground water main. When a fire occurs, firefighters can open the valve on the hydrant to release a high-pressure water supply. The water can then be directed onto the fire to help control and extinguish it. Fire hydrants are an essential part of firefighting infrastructure in cities and towns.
