The right tool for the job
Once upon a time, users could hook up their surveillance camera apparatus to their desktop hard drive, and hope for the best. With time, it became apparent that a specialised storage device, built-for-purpose for a demanding surveillance environment, would serve the task much better.
For clarity sake, the average desktop drive can still store surveillance feed, and a lot of people still employ them for this purpose, but such devices will not give you nearly the performance and stability a surveillance drive will.
According to IHS Markit, the video surveillance industry is having to accommodate a rising tide of data storage requirements. The proportion of higher resolution surveillance cameras shipped is increasing. As are data retention times and the use of video surveillance footage in applications other than just security. These factors and more are stimulating growing demand for scalable, flexible data storage products which can cope with the challenging requirements of modern video surveillance systems.
A security system in say, a shopping centre, could be recording footage from hundreds of cameras in HD 24 hours a day. Such extreme environment requires a storage system to boot.
For truly effective surveillance storage, you need a drive that can process large volumes of video feed, has the capabilities to manage and capture multiple streams of HD foot- age, is designed for efficient power consumption for 24/ 7 read/write recording and the assurance that your footage will be there when you need it. That is, a system that can record accurately with no loss in quality.
More specifically, an effective security surveillance system requires the ability to constantly write multiple streams of HD footage to the disk as efficiently and as accurately as possible. A failed drive, or even just a few seconds when a hard drive drops frames, could mean the loss of critical information when needed most.
The demanding workloads of video and surveillance applications require hard drives with specialised features to accommodate high-write workloads, always- on demands and considerable amounts of video content from multiple camera streams.
A normal hard drive, in contrast, is designed to operate for a period of say 8 hours daily for a 5- or 6- day week, thus these are built with a lower performance threshold. Any longer than that and the chances of failure multiply.
Surveillance cameras are an expensive investment. It thus makes no sense to splash on expensive camera network only to be let down by a constantly failing storage drive. Though a surveillance HDD will be slightly expensive at the outset, it will be cheaper to operate in the long run as it does not need regular maintenance or upgrade due to multiple failures.
Another important aspect is that a surveillance drive enables long-term retention of important video archives—a key need for many video security environments. In fact, across the GCC, government regulations mandate up to 180 days surveillance storage.
The Toshiba S300 surveillance HDD is such a drive.
The Toshiba 3.5-inch S300 Surveillance Hard Drive is designed and tested for 24/ 7 reliable surveillance, built for capacity, and longer content retention.
With up to 10 TB of storage capacity and support for up to 64 video cameras, the S300 ensures missioncritical surveillance continually records. Real-time drive performance allows higher-resolution video recording and streaming and longer content retention.
A 256 MB buffer and high transfer rates meet the demands of surveillance data from higher-resolution camera streams. Improved realtime drive performance is achieved through Toshiba’s Dynamic Cache Technology optimising read and write cycle cache allocation through an on-board cache algorithm and buffer management.
Regular hard disk drives without RV sensors can affect the performance of a multi-bay system by generating ‘knock- on’ vibration.
The S300 ensures high reliability by minimising vibration effects through control and sensing technology. Multiple sensors detect the slightest shock and built-in RV sensors also compensate for rotational vibration - eliminating the possibility of ‘ knock- on’ vibration in multibay surveillance systems.
