In the security monitoring system, dead space is undoubtedly the biggest weakness in video surveillance. We have learned from past cases that there have been many cases of loss due to video surveillance dead ends. Because of the problem of video surveillance dead angles, safer supplements are also born in the surveillance system. Audio monitoring complements this flaw.
We all know that the principle of sound propagation is very different from light. The sound is based on the vibration of the sound source and requires media (gas, solids, liquids, etc.) to be extruded. It is a circular waveform that spreads in all directions. Therefore, monitoring microphones designed for omnidirectionality come in handy. As long as there is a certain loudness in the monitoring area. Pickups can be picked up and transmitted to the output or stored.
Most monitor pickups are designed to be highly sensitive and omnidirectional. This is all to meet the needs of the monitoring area. As an omnidirectional monitoring device. The monitoring pickup can supplement the defects of video surveillance in the monitoring system to achieve the “no dead angle†monitoring effect.
Monitor the pickups for no dead ends
Monitoring dead spots is where monitoring video cannot be observed. We all know that no matter how many 360 degrees the camera monitors, there is no guarantee that there will be no dead angle problem within the monitoring range. Because of the principle of camera lens work, 360 degrees cannot be seen at all (because the light is transmitted in a straight line or there is a corner of the screen in front of the screen).
