On the other hand, the network camera itself is intelligent, it can be a different time, activities, events
or images from the line to determine the video stream sent over the
network frame rate used by
And resolution. Therefore, in
most cases, the camera will use only 10% of the time to send those who
should be recorded and archived video information, while the remaining
90% of the time, no data will be passed.
Misunderstanding # 8: an important video information network is not secure
Through the IP network transmission of video information is important unsafe.
Facts: While Internet is mainly used to pass on public information, but
as long as the correct use of network security measures (such as
firewall, VPN and password protection, etc.), it can also be
Some security requirements for high-sensitive business. As we all know,
many banks and financial institutions around the world via the Internet
are often carried out within the scope of various types of financial
business, then for
Relatively low security requirements in
terms of video surveillance applications, Internet apparently also can
be a reliable bearing media. This corresponds to the analog surveillance
system can not use Renhe An
Full encryption or
authentication mechanism, anyone can take the line by way of easy access
to transmission lines of video information, and even their own fake
error video information sent to the monitoring center
Monitor, so that the video surveillance system complete failure (just as
many movies as the plot). This situation the use of effective security
measures in the IP surveillance system is unlikely to occur Of.
Misunderstanding # 9: No other technology high reliability
Ip Video surveillance technology, high reliability, no other technology, for example, the
network goes down, the system will not be able to continue working.
Facts: Early in the 1960s and 1970s, IP network infrastructure to be
developed first, how to ensure that the network has redundancy built
into the IP network must be considered when the primary
Factors. IP network technology of today, the network used in the
transmission links, application servers, storage devices, and switching
and routing equipment, spare resources can be configured, or the main
link in the main set
Equipment failure, the standby link and
equipment can still maintain the normal operation of the system. In the
IP-based network systems, storage devices can be deployed in a remote
secure location, the server can
A spare power supply, the
system can be used to support hot-swappable RAID drives, memory and
dual-card self-recovery and other measures to ensure reliability.
Although the terms for a small network system Can not use all these
security measures, but based on components of high quality IT solutions
in any case than the traditional CCTV or DVR solution is more reliable.
In addition, the use of standard Servers and network equipment, IP
surveillance system for the replacement of failed equipment, time and
cost required for the DVR system than the closed lower.
Misconception # 10: IP monitor universal needs at least five years.
Facts: This is undoubtedly one of the biggest misconceptions! Since the
Axis in 1996 launched the world's first network camera since it has
been sold around the world, more than 50 million units of these
so-called
"Future" products, while the market for IP
surveillance systems are still growing concerns and needs. Either from
the system's overall cost, overall performance, reliability, or other
aspects of Standards, IP surveillance systems have been proven are now a
mature solution. With IP surveillance technology continues to improve
and spread, IP surveillance systems will also in future security market.
