All big and small surveillance systems require a dependable HDD storage mechanism. A good quality centrally located HDD is important to securely and reliably record feeds from different cameras and this can later be used for greater goods like improvement of traffic system, better security and much more.
Surveillance market will rapidly grow in near future with analysts predicting a growth to over $4200 million by 2017 only. Clients demand Reliable, write-optimized drives designed for a 24 x 7 environments, multi camera support and HD video streaming. To deliver on these parameters, it’s important to choose the right HDD.
Factors to be considered while choosing an SDD
Depending on your system workload, there are several factors you should consider like:
- How often will cameras be running and recording?
- How long do you need to keep your footage? – You are recording for personal or professional needs?
- Where will you be storing and streaming your data? – will you have a centralized location for storing and streaming all data?
- The level of performance you expect from the drive? – you have to consider what kind of analysis you wish to do with the recorded data.
- How many drives does your system support?
Seagate Video 3.5 HDD and Seagate Video 2.5 HDD
Both these HDDs are meant for low cost, personal use simple to install systems. As the name indicates, these drives are available in 3.5 Inch and 2.5 Inch form factors.
Seagate Video 3.5 HDD shows sustained data rate of 180 MB/ second and users can choose storage capacity ranging from 250 GB to 4 TB (480 hours of video recording). Annualized failure rate (AFR) is just 0.55 percent which makes it quite reliable.
These drives supports 18 simultaneous streams of HD content and are designed for 24×7 operation suited to always-on demands DVR devices.
These drives are suitable for home surveillance systems, consumer DVRs, Home cinema PCs and servers and Cable, satellite and IPTV set-top boxes.
Seagate Video 2.5 HDD with max sustained data rate of 100 MB/ second can support up to 12 HD streams at a time. The major advantage of using these drives is their compact form factor. For the same capacity, Video 2.5 HDD takes one sixth space of Video 3.5 HDDs and consumes 50 percent less power.
Seagate Video 2.5 HDDs are suitable for small scale applications like In-camera or surveillance systems, Home cinema PCs, Karaoke and audio jukeboxes, Cable, satellite and IPTV set-top boxes.
Seagate SV35 HDD
Seagate SV35 HDD support data rates of up to 210 MB per second well suited for Network Video Recorder (NVR) system designers and developers. This high performance drive, with 64MB of cache, has been optimized for high write load for 24 x 7 video surveillance systems.
These drives support up to 32 camera streams at one time. AcuTrack technology helps in improving reliability even in tough operating environments. 1TB-per-disc technology provides costeffective1TB, 2TB and 3TB capacities.
Enterprise Capacity 3.5 HDD
Enterprise Capacity 3.5 HDDs are meant for ultra high capacity surveillance solutions which demand HD streaming, video analysis and ample storage space. They can easily handle more than 100 Camera’s simultaneously or even 10+ bay systems.
Users get the option for Up to 6TB per drive for maximum density server and storage solutions. Enterprise Capacity 3.5 HDDs are fit for high scale 24 x 7 surveillance. Seagate PowerChoice technology offers customizable power savings thus allowing for 90 percent energy saving. You can extract 6Gb/s performance in both SAS and SATA interfaces.
For enhanced security, you can choose from self-encrypting Drive and SED FIPS 140-2 options from the ES.3, ES.2 and ES drive generations. If you are looking for large scale surveillance, you will need the highest capacity possible and will need to save money by power efficiency – something Enterprise Capacity 3.5 HDDs can deliver.
Seagate Surveillance HDD
Seagate Surveillance HDDs have been designed to operate in 24 x7 multi-drive surveillance solutions. Precision tuned for surveillance workloads, these drives can support 32 cameras per drive and 16 drives per system simultaneously.
Improved Time-To-Ready makes them suitable for motion sensing cameras. RAID and Idle 3 support is present for multiple drive support and Rotational Vibration (R/V) sensors further enhance performance. These drives are best suited for Multi drive systems. One Million hours of MTBF (Mean time between failures) in itself demonstrates high reliability.
So as you can see, there are different types of HDDs which you can choose from according to your needs. Most people care about effective recording and efficient playback. But depending on how sensitive the subject of surveillance is, a few frame drops can mean a lot.
