The surveillance industry has started to update their storage technology to improve performance.
Here are two senarios:
1) During the nighttime, there has been a break-in at a company location and the perpetrator has been caught on tape. The recording is stored and reviewed at a later time, only to find that due to compression, the images of the perpetrator is obscured. And also, some frames have been dropped because of unstable data recording. This makes identification much harder.
2) During the nighttime, a person is picked up by the surveillance cameras. With fast-working data analytics, the system notices that there is someone in the restricted area and simultaneously notifies the appropriate personnel. The infiltrator is caught on the property, and the high quality of the recording helps correctly identify the person.
Which senario would you rather deal with?
The thing is that most surveillance systems use today hard disk drives (HDDs) for storage purposes. While this works perfectly well for basic setups, it can be a obstruction for implementing modern surveillance features.
The use of solid state drives (SSDs) for data recording is a solid step forward towards fixing this, as it gives the user access to data analytics that enables advanced features such as facial recognition and automated traffic control systems.
What is the reason HDDs are still so commonly used in surveillance? As technology advances, SSDs can now provide a cost-efficient alternative to many traditional surveillance setups.
Flash memory based solid state storage devices (SSD) are used in the applications mentioned above. EarthTron is a distributor of Micron Flash Memory and other electronic components. Click the button below to see our Micron Part Offers:
Another even more clear advantage for the SSD is speed, which has also been the main selling point ever since this form of storage entered the market. Modern surveillance setups don't just record and store data, but they are also seeing increasing requirements for data analytics. This means handling on-the-spot operations like facial recognition and then taking immediate action once a hit is made. The system is able to handle demanding simultaneous read and write operations, which HDD technology is poorly equipped to handle.
Capacity and price
But even with the two elements discussed above working in favor of the SSD, there are two projections where the HDD still stands strong: namely price and capacity. For those just looking for a simple and affordable system, an HDD-based solution can be a perfectly good fit.
This holds true for low-performance HDDs, but once you reach the 10K-15K RPM drives, it's a different story. These drives have platters that spin up to twice as fast as normal drives and have significantly increased performance. However, prices increase and capacities drop dramatically, even being surpassed by higher-end SSDs.
So, if your application needs to perform above that of a basic surveillance setup, the easier solution is to just opt for an SSD. By also calculating in a higher overall reliability, the total cost of ownership will be in favor of the SSD solution.
- The Innodisk 2.5" SATA SSD 3MV2-P offers up to 2TB capacity coupled with high speed and stable performance. Through the smart integration of firmware and hardware, the speed and performance required by modern surveillance solutions are fully met.
- 2.5" SATA SSD 3MV2-P products provide high capacity flash memory (SSD) that electrically complies with Serial ATA (SATA) standard.
Another aspect to consider is the technology. Although referred to as drives, SSDs don't actually have any moving parts. This means that they are naturally more adept at taking a beating both in terms of shock and temperature; it also means less heat created during operation. By comparison, an HDD has a head that flies on a thin layer of air above the platter. Any strong enough vibration or shock will lead to a head crash and data being lost. For any recording performed onboard vehicles or in hostile environments, an SSD should be the primary choice for storage.
A combination of the two storage systems may offer the best solution, where HDDs handle data archiving while SSDs take care of any operations requiring high-speed or high-quality recordings for data-analytics. A solid state device might also be worth considering as an addition to already existing setups as it can drastically increase system performance.
Theres a price gap between the two solutions, SSDs are already more than qualified to enter the market. SSD technology has already done away with many of its earlier issues, it can now fulfill the stricter requirements of modern surveillance, and it will expand on what is possible with a well implemented surveillance system.
