WD increases line of special hard drives for surveillance

Not every user thinks about it, but there are differences in hard drives, thought about the use you are going to make of them. For example, keeping a surveillance camera recording 24/XNUMX is quite demanding on a storage unit. To serve this market, the WD has a series of HDs created specifically for surveillance systems, and is expanding the product range with a new model.

In 2013, the WD created the line Purple, aimed at DVR (digital video recorder, or digital video recording). Unlike traditional hard drives used in computers, these were prepared for the continuous use of surveillance systems, with lower consumption, lower temperatures and emitting less noise. The technology IntelliSeek developed by WD calculates the speed of access to the media according to the user's need, and with that it manages to reduce the power of the HD by up to 3 times.

But the most important part of the line firmware Purple is AllFrame, which prevents crashing in live recordings. When one HD writes something to disk with an error, it tries to correct the error, which doesn't work for surveillance cameras that no longer have the original image and keep trying to record new images, which can cause the system to freeze with a few seconds or even stop completely. As AllFrame, the system will accept the loss of some pixels but continue recording without losing anything.

O WD Purple have sizes of 1TB, 2TB, 3TB, 4TB, 5TB e 6 TB, and is made for installations of up to 32 channels, with up to 8 hard drives. how is it done for DVRs, the cameras need to be installed and connected directly to the recording system.

The novelty of the line is the new WD Purple NV, made for IP-connected camera systems. The appliances of NVR (network video recorder, or network video recorder) has more recording freedom than DVR, and therefore can have more than 32 channels at once. The NV has a 4 TB and a 6 TB version, and allows up to 64 cameras, aimed at medium businesses.

Another surveillance product is the WD Re, made for large enterprise and mission critical servers. Unlike the others, the Re has no channel limitation, being able to control numerous cameras at once and is designed for high-volume work. O Re has versions between 250 GB and 6 TB.

In addition to storage systems, the WD Red, to back up the Purple HDs. According to WD, consumers and businesses are not used to performing backups of surveillance systems. Unlike expected, the greatest need to use the Red is not loss of information, but cases of theft of the DVR ou NVR. With network storage, even if the hard drive is taken, there will still be a copy of the recorded footage.

A WD believes that the surveillance market will have high growth in the coming years, reaching up to 10 billions of dollars worldwide in 2018. Brazil stands out in Latin America, currently having a market estimated at 279.2 million U.S. $, and which will accompany global growth.

executives of WD recognize, however, that the Brazilian market suffers from the use of non-specialized HDs for surveillance in devices of this type. On the one hand, they attribute this to a lack of knowledge, on the other hand, to the higher cost that the product may have. despite the WD having a plant in Brazil, surveillance HDs are imported. When they arrive here individually, due to taxes, they can be 15% to 20% more expensive than other models. But if you buy the HD integrated into a surveillance system, it will enter as an input, and pay less fees, being very close to the value of other hard drives here in Brazil. Among the partner companies of WD that send the HDs Purple factory, is the Brazilian intelbras.
