Surveillance cameras are usually kept for a few days.

The monitoring of residential areas can basically be kept for about seven days, cinemas and hotels generally keep it for fifteen days, and banks can keep it for three months to six months.

In theory, surveillance cameras can be kept indefinitely, but in practice, they will only be kept for one week to three months. More careful financial companies will extend the monitoring and storage time to one year. This phenomenon is mainly due to the consideration of cost and full use of resources.

Influencing factors of storage time of surveillance camera

Generally, the storage time of a camera is linked to the application memory, 32G can be stored for 90 days, and 64G can be stored for more than 180 days. At present, the longest storage time should be 16G storage of Kidka72, and the storage time is about 70 days. General surveillance cameras will be kept for a week to a month, and long ones will be kept for 3 months.

The storage time of general household cameras is related to the capacity of their hard disks. Generally speaking, the larger the capacity, the longer the storage time. If you don't set it, once your hard disk is full, the new information will overwrite the old information. Secondly, if the number of cameras connected to the hard disk increases, the storage time of the hard disk will also decrease accordingly.
