How long does it take for Le Orange backup monitoring?
The surveillance video converts the image signal into digital information and then stores it in various memories. These storage devices are usually hard disks, and can also be recorded as optical disks or stored in cyberspace. So theoretically, as long as there is enough storage space, or the digital information is continuously transferred to other storage devices, the surveillance video can be stored indefinitely.
Of course, in fact, for cost reasons or considering various factors, the stored information is generally kept for a period of time, and it is basically meaningless to continue to save it. Then the original information will be overwritten by new information, which can save limited storage space and reduce storage costs. So in general, the video of the monitor will be saved according to the requirements of different industries and different places. If it is common monitoring information such as community monitoring, it will generally be kept for about a week; If it is the monitoring information of hotels, entertainment places and other public places, it is generally kept for about half a month; If it is in banks, finance or other important and key places, it will be preserved for more than a month or even a year or even longer.
