Remote DVR surveillance provides you with many unique
features and options that you just simply cannot get with
standard surveillance methods. With remote DVR security
systems, you not only have access to view and monitor video
feeds remotely, you also have the ability to perform many
administrative functions remotely as well.
The purpose of this article is to look behind the scenes
to learn more about how this remarkable technology works. We
will also briefly review a product line that incorporates
this technology and provide information for you to view one
of their security DVR demos online.
When it comes to remote DVR systems, there is more going
on behind the scenes then you may realize. The basic concept
behind remote video surveillance is to provide access to
video images and camera configuration information through an
IP network. In order to facilitate this process, most DVR
recording devices incorporate a web server, which provides
the ability to host digital images and other camera control
functions on its own web page. With a web server in place to
host the necessary digital information, any authorized user
can log in through a standard web browser and gain access to
the web page and corresponding data through standard HTTP
protocol.
When you set up your remote DVR system, there are several
important things to consider that will ensure you get the
most optimal benefits from your system. These include:
- A static IP address -- Utilizing a remote DVR
device and corresponding web server will require you to
have a static IP address assigned to the device.
- Carefully consider compression rate and
transmission format -- The compression rate and
transmission format of the captured video data will have
a big impact on the quality of the image displayed. In
general, the better the image quality, the more disk
space required to store the image, and the longer it
takes to transmit it remotely. Compression rates and
image resolutions do vary by camera, but you can
configure file transfer settings from your DVR device as
well.
There is a wide variety of remote DVR devices available
on the market. You can find many quality offerings from a
number of companies that specialize in these devices. A
company called
OptiView is just one example. They offer a wide
selection of remote DVR units that can support from four all
the way up to 48 surveillance cameras. Their DVRs are
designed to facilitate remote video access as well as remote
camera control abilities. They offer 704X480 display
resolution and H.264 real time rate of compression. This
functionality ensures you will have access to quality
playback images without the skipping that often occurs
during remote video playback.
Incorporating a DVR device that offers remote
functionality will add a tremendous amount of versatility to
your surveillance system. You will gain access to view live
and recorded video feeds, search stored video archives, set
and change user settings, change camera settings and
positions, and manage individual camera recording schedules.
