Storage Solutions
Quality video surveillance can be vital to the security of your
business; advancements in video technology have
spurred a dramatic
increase in the adoption of IP technology cameras which offer high
resolution digital images that
are far superior to those of their
analogue counterparts. The resolution provided by IP cameras enables
clear view of
objects of interest, such as facial details and license
plate numbers, to be digitally zoomed and viewed clearly.
There is always a trade-off between the quality of the image, video
recorder performance, and the cost of storing
and maintaining hours of
footage. Megapixel cameras are the clear choice when you need
uncompromising video
quality and easy installation. Taking full
advantage of megapixel cameras requires pairing with a storage solution
that
delivers performance, flexibility and scalability to meet camera
demands and retention objectives.
Network Attached Storage
MOBOTIX Cameras are known for their high quality megapixel
Imaging IP Cameras.
Their versatile line of high
resolution
cameras brings video surveillance to a higher level, providing
megapixel resolution (1024 x 768, 1280 x 960,
2048 x 1536)
video streams with audio and scalable frame rates.
Their
cameras store these high resolution images more efficiently
than other cameras, thereby requiring less network
bandwidth and placing a lower demand on the network
storage device.
Recent testing of Snap Servers in the MOBOTIX
Camera Lab has shown Overland Storage Snap
Servers to be an ideal network storage solution for handling
the
demands from multiple high resolution camera streams,
while offering reliability, scalability, and ease of use.
The
Snap
Server is easier to maintain and requires much less expertise
to manage than a standard PC.
Built on the Guardian Linux-based Operating System,
Overland Storage Snap Servers provide NAS storage for file
storage and sharing, or as part of a backup to disk solution –
whether at a single site, or across multiple remote sites.
Snap Servers are available in a variety of sizes, from 160GB
desktop units to 19-inch rack mount systems that scale
from
1TB to 66TB of raw storage capacity to fit a variety of video
surveillance storage needs. Most Snap Servers also
support
multiple RAID data protection schemes, so critical video files
remain safe and are available when they are
needed.
Each Snap Server can support
multiple cameras to simplify the installation and ongoing
management of the video
system. And the modular
expandability of the Snap Server 520 and 650 systems enable
the flexibility for future growth,
as well easily facilitating an
archiving solution, should that be desired.
Snap Servers provide cross-platform support, including NFS
and CIFS, and easily integrate into existing networks and
security infrastructures on a single device, providing a safe
and secure video archiving solution.
SD Card
SD memory cards are an innovative, always evolving bridge media powering the future of the digital world. SD
memory
cards deliver high-performance products that allow consumers to
quickly capture video, photos, and sound in a
reliable, easy-to-use
format
SD technology is the de-facto industry standard for mobile phones, digital cameras, MP3 music players, personal
computers, printers, car navigation systems, electronic books, and other consumer electronic devices. SD
technology is used in some 400 products across dozens of product categories and in more than 8,000 models.
SD memory cards are available in standard and high-capacity formats along with a variety of speed classes. A next-
generation SD memory card specification, SDXC (extended Capacity), will soon be released to SD Association members
who will create cards and devices that support its greater memory capacity and faster performance speeds. The
cards have the broad interoperability and compatibility needed to ensure that its applications will continue to expand
far into the future.
Universal Serial Bus
A USB flash drive consists of a NAND-type flash memory data storage
device integrated with a USB (universal serial bus)
interface. USB flash
drives are typically removable and rewritable, much smaller than a
floppy disk (1 to 4 inches or
2.5 to 10 cm), and most USB flash drives
weigh less than an ounce [1]. Storage capacities typically range from 64
MB
to 64 GB with steady improvements in size and price per gigabyte. Some allow 1 million write or erase cycles and have
10-year data retention, connected by USB 1.1 or USB 2.0.
USB flash drives offer potential advantages over other portable storage
devices, particularly the floppy disk. They
have a more compact shape, operate faster, hold
much more data, have a more durable design, and operate more
reliably
due to their lack of moving parts. Additionally, it has become
increasingly common for computers to be sold
without floppy disk drives.
USB ports, on the other hand, appear on almost every current
mainstream PC and laptop.
These types of drives use the
USB mass storage standard, supported natively by modern operating
systems such as Windows, Mac OS X, Linux,
and other Unix-like systems. USB drives with USB 2.0 support can also operate
faster than
an optical disc drive, while storing a larger amount of data in a much
smaller space.
Nothing actually moves in a flash drive: the term drive persists
because computers read and write flash-drive data
using the same system
commands as for a mechanical disk drive, with the storage appearing to the computer
operating system and user interface as just another drive.
A flash drive consists of a small printed circuit board protected inside a plastic, metal, or
rubberised case, robust
enough for carrying with no additional
protection—in a pocket or on a key chain, for example. The USB connector
is
protected by a removable cap or by retracting into the body of the
drive, although it is not liable to be damaged if
exposed. Most flash
drives use a standard type-A USB connection allowing plugging into a port on a personal
computer.
Local PC Storage
It is possible to utilise the client pc for storage of clips, this is
done by requesting the recording device (i.e. Camera)
to record in to a
shared folder on the PC. This system does have some security drawbacks
and also could restrict
alternative clients' access to historic clips.
In addition to this the client pc would also have to be continually
switched
on and connected to the network.
This option for storage could be an viable in some systems but if a
network is available NAS storage may be a more
fault tolerant option and
would also provide a more future proof solution.
