TRENDnet TVIP252P User Manual

PREFACE

Thank you for purchasing the TV-IP252 SecurView PoE Dome
Internet Camera, a standalone system that can be connected
directly to an Ethernet or Fast Ethernet network.

The camera features the latest Motion JPEG and MPEG-4 image
technology, advanced management functionality, and GPIO
connectors (e.g. connecting to the door sensors or alarm bells),
allowing you to record streaming video (Motion JPEG or MPEG­4 ), enable motion detection, and setup automated FTP/Email/
Network Storage service for security.

The audio function (connected external microphone and audio-out
device like the active speaker) of the camera allows you to
deliver/receive sound to/from the camera. In addition, the superior
lens and hardware design enable the camera to capture high
quality images even in the low-lux condition.

Compared to the conventional PC Camera, the camera features a
built-in CPU and Web-based solutions that can provide a cost­effective solution to transmit the real-time high-quality video
images and sounds synchronously for monitoring. The camera
can be managed remotely, so that you can use a Web browser to
access and control it from any desktop/notebook computer over
the Intranet or Internet.

The simple and versatile installation allows you to integrate it into
your network environment easily. With comprehensive
applications supported, the camera is your best solution for
demanding surveillance and remote monitoring applications.

The camera supports RTSP (Real Time Streaming

Protocol), which is a technology that allows you to view
streaming media via the network. You can view the real­time video with the Quick Time player or RealPlayer. To
view the real-time streaming image on your computer, open
the Web browser and enter the RTSP link:

rtsp://(IP address of the camera)/mpeg4.

 Remote Control Supported
By using a standard Web browser or the bundled Ultra

View software application, the administrator can easily
change the configuration of the camera via Intranet or
Internet. In addition, the camera can be upgraded remotely
when a new firmware is available. The users are also
allowed to monitor the image and take snapshots via the
network.

 I/O Connectors Supported
The I/O connectors (2-in/1-out) of the camera provide the

physical interface to send and receive digital signals to a
variety of external alarm devices. You can configure the
settings and control the device from the GPIO Trigger
setting of Web Configuration.

 Multiple Platforms Supported
The camera supports multiple network protocols, including

TCP/IP, SMTP e-mail, HTTP, and other Internet related
protocols. Therefore, you can use the camera in a mixed
operating system environment, such as Windows 2000,
Windows XP and Windows Vista.

 Multiple Profiles Supported
The camera supports multiple profiles simultaneously, so

that you can separately set up different image settings
(such as image quality and frame rate) for the three video
types of the camera: MPEG4, MJPEG, and 3GPP.

 Multiple Applications Supported

Through the remote access technology, you can use the
cameras to monitor various objects and places for your own
purposes. For example, babies at home, patients in the
hospital, offices and banks, and more. The camera can
capture both still images and video clips, so that you can
keep the archives and restore them at any time.

multiple ranges for the camera.

For example, when you enter 192.168.10.50 in Start
IP Address and 192.168.10.80 in End IP Address, the
user whose IP address located within 192.168.10.50
~ 192.168.0.80 will not be allowed to access the
camera.

- Deny IP List: The list displays the range setting(s) of

IP addresses that are blocked to access the camera.

workstation to give its own IP address.

Communication has four components: sender,
receiver, message, and medium. In networks, devices
and application tasks and processes communicate
messages to each other over media. They represent
the sender and receivers. The data they send is the
message. The cabling or transmission method they
use is the medium.

In networking, two devices establish a connection to
communicate with each other.

Developed by Microsoft, DHCP (Dynamic Host
Configuration Protocol) is a protocol for assigning
dynamic IP addresses to devices on a network. With
dynamic addressing, a device can have a different IP

systems, the device's IP address can even change
while it is still connected. It also supports a mix of
static and dynamic IP addresses. This simplifies the
task for network administrators because the software
keeps track of IP addresses rather than requiring an
administrator to manage the task. A new computer
can be added to a network without the hassle of
manually assigning it a unique IP address. DHCP
allows the specification for the service provided by a
router, gateway, or other network device that
automatically assigns an IP address to any device that
requests one.

The most popular LAN communication technology.
There are a variety of types of Ethernet, including
10Mbps (traditional Ethernet), 100Mbps (Fast
Ethernet), and 1,000Mbps (Gigabit Ethernet). Most
Ethernet networks use Category 5 cabling to carry
information, in the form of electrical signals, between
devices. Ethernet is an implementation of CSMA/CD
that operates in a bus or star topology.

Fast Ethernet, also called 100BASE-T, operates at 10
or 100Mbps per second over UTP, STP, or fiber-optic
media.

Firewall is considered the first line of defense in
protecting private information. For better security, data
can be encrypted. A system designed to prevent
unauthorized access to or from a private network.
Firewalls are frequently used to prevent unauthorized
Internet users from accessing private networks
connected to the Internet, especially Intranets all
messages entering or leaving the intranet pass
through the firewall, which examines each message
and blocks those that do not meet the specified
security criteria.

Short for hexadecimal refers to the base-16 number
system, which consists of 16 unique symbols: the
numbers 0 to 9 and the letters A to F. For example,
the decimal number 15 is represented as F in the
hexadecimal numbering system. The hexadecimal
system is useful because it can represent every byte
(8 bits) as two consecutive hexadecimal digits. It is
easier for humans to read hexadecimal numbers than
binary numbers.

This is a private network, inside an organization or
company that uses the same software you will find on
the public Internet. The only difference is that an
Intranet is used for internal usage only.

The Internet is a globally linked system of computers
that are logically connected based on the Internet
Protocol (IP). The Internet provides different ways to
access private and public information worldwide.

To participate in Internet communications and on

Network Address Translator generally applied by a
router that makes many different IP addresses on an
internal network appear to the Internet as a single
address. For routing messages properly within your
network, each device requires a unique IP address.
But the addresses may not be valid outside your
network. NAT solves the problem. When devices
within your network request information from the
Internet, the requests are forwarded to the Internet
under the router's IP address. NAT distributes the
responses to the proper IP addresses within your
network.

A network consists of a collection of two or more
devices, people, or components that communicate
with each other over physical or virtual media. The
most common types of network are:

LAN – (local area network): Computers are in close
distance to one another. They are usually in the same
office space, room, or building.

WAN – (wide area network): The computers are in
different geographic locations and are connected by
telephone lines or radio waves.

A network protocol that can automatically negotiate
the highest possible transmission speed between two
devices.
