Residential property monitoring system adopts elevator dynamic monitoring mode in advance, that is, when someone enters and exits the elevator, the system automatically starts and videos. How to set it? Your dynamics can only judge the dynamics of getting in and out of the elevator for a period of time. If people don't move after entering the elevator, they can't be detected. If I remember correctly, some dynamic videos can be set to a longer duration. Having dynamic video again is not ideal for me. The hard disk really doesn't have to be so big.
