1) Buying multiple cloud recording packages can superimpose the cloud recording space capacity, and there is no upper limit

  2) The use period of each package is calculated independently, and the cloud recording space will be reduced by the corresponding capacity after the package expires

  3) If the cloud recording has multiple packages service and multiple devices are bound, if one of the packages expires, the total remaining capacity of the cloud recording cannot satisfy the binding of several devices, it will start from the last one in the binding list unbind, until the number of currently bound devices meets the capacity limit number binding, the corresponding stored cloud videos are cleared in a first-in-first-out manner, until the maximum storage capacity of cloud video is met
