Is there a recording of the video of the underground garage in the community?

The monitoring of the community is generally not video, but mostly screen monitoring. Generally, there is no recording, only video recording.

As we all know, when the car starts and stops in the garage, it will produce a lot of gases harmful to human health, such as nitrogen oxides, carbon monoxide, lead particles, sulfides and so on. Among them, carbon monoxide has the highest gas concentration and the greatest harm. Moreover, compared with the above-ground buildings, the underground buildings are highly airtight and indoor pollutants are not easy to spread. Therefore, it is particularly important to ensure that the concentration of harmful gases is controlled within the scope stipulated by relevant health standards for the ventilation design of basement garages, and it is also an important content to measure the effect of mechanical ventilation.
