What is a network DVR?
A Network DVR is a DVR linking CCTV
cameras together, and records all signal to Hard Disk, but at
the same time, provide remotely access from Internet or computer
network to download, replays record, being controlled by remote
user but without affecting normal daily operations.
Our DVR is TCP/IP based, that means:
Flexibility and Compatibility:
When every computer connects to the Internet, a unique IP
address is allocated to the computer, IP addresses are used to
locate computer locations in the world of Internet. When user's
computer and the DVR are IP-based, they can communicate with
each other and share information or resources.
DVR and Network DVR
In dealing with situation of small to
mid-large businesses, for instance, retail stores, chain stores,
offices and showrooms, this is not desirable to deploy DVR
operator at the site. Stores got limited space, security cost
would be unacceptable to small-mid businesses that actually do
more harm than good. The only solution is to reduce man power in
the area of security.
Using VCR-based technology, records are bounded
in tapes. But with Network DVR, records are digitalized, system
links and distributes all the capturing images and records
together by computer network or Internet. Record can be
transmitted automatically that user can monitor every site whom
wants, at home, or at anywhere.
This revolutionary function is particularly useful to small-mid
businesses owners, they can monitor their property while on
traveling or at home.
The concept of Network DVR behind the scenes illustrated as
1. With dedicated cameras deployment on targeted site, and all
capturing images transmitted to VisonNet's Network DVR.
2. Network DVR handled all the things basically. Digitalized the
image and record to "Storage Buffer", that is a device for
storing records in the Network DVR. By Internet or computer
network access, all the records and capturing images are
distributed to authorized computers and users.
ps: "Storage buffer" is a device inside the Network DVR of which
is used to store records. Generally, when system running 24-hour
a day non-stop recording with 12.5 Frame/sec video quality,
records would be stored at the "Storage buffer" for one month
without being erased.
3. If necessary, monitor can be installed and connected to the
Network DVR, just like VCR-TV, all the images would be
displayed, and system allow users to change surveillance
settings with authorization password.
4. With the help of Internet, user can access to the Network DVR
to download or replay record, monitor or record real-time by
generic desktop/notebooks computers.
Network DVR (Digital Video Recorder) is a self-contained
surveillance system that stores high quality video records longer
than any other conventional DVR solution. As all the records are
being controlled by Advanced Data Preservation and Circulation
Mechanism, system will recognize all important data, such as
data generated by Motion Detection, it will preserve them in
storage buffer and never destroy or erase unless authorized user
do it manually. Other unimportant data would be erased for
records replacements. System comprises all the
necessary components for recording and viewing over the network:
CPU, Ethernet interface, memory controllers, device interfaces,
video compressor, and Hard disk storage device.
With the power of Network accessing capability, VisionNets'
Network DVR surpasses other generic DVR in the market.
