A Brief Account of the CCTV Camera Storage Requirements



All visual or audio data these days are stored in digital format. With every passing day, surveillance requires transmission of terabytes of storage for multiple cameras that are operational in a given property. Thus, the need for storage of data is growing by leaps and bounds every day.

And when we speak about the storage requirements, the chapter is divided into two categories - short term and long term storage.

Short Term Storage

Short term storage can be defined as the recycling of available storage space by using the FIFO (First-In-First-Out) Principle. Put in the other way, if your drive has a storage capacity recording for say, 15 days, an incident that has taken place 17 days back cannot be retrieved.

The images will be overridden by the proceedings of the last 15 days. Therefore, it is up to you to increase the storage capacity of your CCTV cameras. This is referred to as the short term storage retention of the security cameras in Perth or in other parts of the city.

Therefore, it is essential you for as a user, to know what storage retention is. You can increase the storage capacity of these security cameras by simply adding a couple of more drives when you have them installed. The number of drives will determine the storage capacity. Some users would ask the installer to make the storage capacity large to preserve even 2 years of data.

However, you need to see if there are any restrictions in place so far as increasing CCTV camera storage capacity is concerned.

Long Term Storage

The term, 'long term storage' defines the drive capacity of storing information for an indefinite period. This typically is possible by backing up the incidents from the short term storage to another domain or media form, and storing them for a longer period and making arrangements so that they are not erased or overwritten. This technique is at times, referred to as archived storage.

The media for long time storage is more or less identical to that of the short term storage. The technology that is used these days for storage still revolves around magnetic HD drives, though there are other technologies in place, like solid-state electronic storage that can be done in flash drives, Solid State Drives (SSD) and SD cards. Optical drives like CD ROMs and DVDs and Blue Ray Disks are getting obsolete.

Long term storage of these CCTV cameras in Perth like in any other place, are not theoretically indefinite, as eventually, the domain will lose data when new feeds get into its memory. Besides, hard drives may lose the magnetic particle polarisation capacity after a prolonged period and may lose the stored data as well.

However, they can retain the data for so long a period that the storage will come in handy to meet your needs.
