For a CCTV system to work properly, you need to keep in mind a few basic concepts, involving since how it works, as well as what type of Storage used for data storage optimization of CFTC and above all, how it scales.
Learn what is CCTV and how to set up this system, using it throughout your ability and potential.
Defined by growtheology, CCTV or closed-circuit television is also the term behind the popular acronym, CCTV from the term closed-circuit television, CCTV.
The function of a CCTV is through video cameras, register/shoot certain points of an environment, sending so the signal to one or multiple monitors. This system is used as a security mechanism and monitoring.
In the current context, the CCTV data storage is of utmost necessity, because it allows the images taken can be used at any time, in several cases, either as evidence of a crime, people recognition, investigations, etc.
Storage and scaling: essential to CCTV data storage
When we refer to the Storage, we mean exactly the hardware that’s goal, exactly the function of storing safely and effectively, data companies. In these cases, data from closed circuit TV.
For it to work the way in the direction of CCTV data storage, you need to essentially that it is sized correctly, otherwise, the system will be subject both to failure as various bugs, generating waste in the it industry of company with several losses.
To guide the choice of best design in Storage, it is necessary to bear in mind the following question: what is the recording time will be used and what the storage capacity will be needed?
To answer these questions above, let’s first understand how does CCTV data storage?
Understanding CCTV data storage
As we know, a CCTV camera will produce videos. These videos can be created in different types of formats, and subsequently sent to the recorder (DVR or NVR). Following the procedures of the demand by the coach responsible for the installation of the TV circuit, the videos and pictures are then stored.
As a rule, is customary, when the system is not yet active, but still in the “paper”, we make estimates of the recording time. 30 days? 90 days? Less? More? The more days of shooting continues, more space required in Storage.
It is therefore important to know the size required space on disks properly, according to the needs of each project, for this way to choose the most appropriate Storage.
Some tips for the Storage size
To proceed in the best possible way the scaling of Storage, we should follow some factors of paramount importance. See some of them below:
STORAGE CAPACITY IMPLIES PLANNING
As in everything in life, it is always necessary to plan. Therefore, when you start a project of CCTV data storage, search have set the amount of Terabytes of Storage.
FACTORS THAT INFLUENCE THE AMOUNT OF TERABYTES
To have defined the amount of Terabytes in Storage required, some factors directly influence the calculation. Among them we have the resolution, the frame rates, codec, and the type of recording, if is continuous or event.
In the case of the resolution, if the recording is made in FullHD, the space required for storage must be larger than files with 4CIF resolution or VGA.
In the same way as if the frame rate pro seconds (frame rate) is 30 FPS, the space required is double than usual, which is 15 FPS.
THE PROJECT VALUE OF STORAGE SET
Another determining factor is to determine the value of the information to be stored in the Storage. To reach such a conclusion, seek to have first of all, at least a sense of how much these data will be stored. It is also necessary to measure the loss of access to these data and finally, how your company can invest in a project of this size.
An option in the case of acquisition costs being higher than the budget of the company, for example, is renting the equipment, for example.
TYPES OF BACKUP
For the correct sizing of Storage, and that has not suffered the loss of data, we must also invest in a Backup policy. The Backup should be set according to the type of security present in the Storage.
NUMBER OF USERS AND SERVERS
Which connection will be used on Storage? To answer this question you need to know on average, the amount of hits. Therefore, knowing the number of users and how many servers Storage will behave, will define whether the connection should be SAN, NAS, iSCSIx, FC or Ethernet, for example. There are cases which indicate that the hybrid solution is the best way.
Always remember that both connections as RAID levels must be defined according to the types of applications that run on the data storage system. That is, in this particular case we are referring to execution of a CCTV system.
HAVE A PLAN B
For more efficient, planned and well prepared is the your data storage system in the digital world it’s common, now and again, we have some setbacks and problems with access to information. In addition to outlining plans to prevent these problems from occurring, if still they arise, you need to know exactly how to proceed.
Snapshots and Backups are a few solutions that you obligatorily must enter in your system, to minimize possible losses.
As we have seen, the CCTV data storage implies a number of details that must be evaluated, studied and calculated, after planned to run.
Thus, minimizes the chances of the system result in errors and failures, allowing the company, greater security on data protection, as well as the internal circuit optimization.
