VPort 251 User’s Manual Introduction
Overview
The VPort 251 is a high performance, 1-channel video encoder with compact form factor that is suitable for installation in a variety of locations, including outdoor camera cabinets. To make installation easier, the VPort 251 supports both panel mounting and DIN-Rail mounting (with DK-35A accessory), and 1 loop-through power output for powering an analog camera. In addition, the VPort 251 provides up to full D1, full frame rate video performance (NTSC: 720 x 480 up to 30 FPS; PAL: 720 x 576 up to 25 FPS) and supports both MPEG4 or MJPEG, making it especially well suited for use with distributed video surveillance systems. A 2-way audio function is also provided for the convenience of real-time communication between system administrators located at the central site, and engineers in the field.
High Performance MJPEG/MPEG4 compression
Video input can be efficiently compressed into MJPEG/MPEG4 video stream packets without delay. This is all done without sacrificing remote monitoring capability or storage. Five levels of compression quality and five different image resolutions are provided to provide greater versatility.
2-way audio supported for a complete surveillance solution
The VPort 251 supports both audio input and audio output for voice over IP communication between a field site and central site. The 2-way audio function not only saves time, but also saves the cost of needing to add additional communication devices (such as a phone).
Compact design and loop-through power output for camera housing installation
The VPort 251 is compact enough to meet a variety of installation requirements, especially as far as the camera housing is concerned. In general, video cameras used in outdoor environments will rely on the camera housing to protect the camera from rain, dust, temperature, and other environmental factors. In addition, the VPort 251 provides a loop-through power output to power an analog camera. This means that the VPort 251 can be installed with analog cameras in an outdoor camera housing.
RTSP streaming for easy integration
RTSP (Real-time Streaming Protocol) is a client-server multimedia presentation control protocol, which enables the interoperability of video devices and software. Hardware or software that supports RTSP streaming can easily identify and decode the video stream without the hassle of codec installation. For example, users can view video images from the VPort 251 directly with Quick Time and VLC, both of which support RTSP streaming.

VPort 251 User’s Manual Introduction
Multicast (IGMP) transmission for network efficiency
Transmitting digital video images via an IP network requires a dozen times the bandwidth required for transmitting general data. For this reason, the efficiency of network bandwidth management is one of the most important issues that determines the performance of a video over IP surveillance system. The VPort 251 supports multicast transmission with IGMP protocol, which can reduce the bandwidth requirements when multiple clients access the same video stream, and greatly increases the efficiency of network bandwidth management.
Easy web access using standard browsers
There is no need to install new software to access the video encoder, since the embedded web server allows users to use any popular web browser to access the video encoder from anywhere over the Internet. As long as you are connected to the network, you will be able to view the same images seen by your cameras.
Support for SNMP V1, V2c, and V3 for easy network management
More and more IP devices are networked for use on one TCP/IP network. To make management and maintenance easier, SNMP (Simple Network Management Protocol) can be used to monitor all of these IP devices.
Built-in 3 area-selectable Video Motion Detection (VMD)
External sensors are not required, since the video channel can be configured to detect motion in 3 areas, making it easy to set up a security system in either your office or the field. And the customizable settings allow you to tune the system for both object size and sensitivity, making the video encoder adaptable to different environments.
Weekly schedule for automated surveillance
The user-defined time period will check security settings on a weekly basis, and send notifications or drive external devices, making the VPort 251 suitable for more versatile applications.
Flexible I/O control for external devices
1 opto-isolated sensor inputs and 1 relay outputs are provided to control external devices, giving system integrators the option of turning an analog system into an advanced security system.
Moxa SoftDVR Lite IP Surveillance Software
To extend the video encoder’s capabilities, Moxa SoftDVRTM Lite IP Surveillance Software, which supports a maximum of 4 cameras in quad, is included free of charge, allowing users to turn their PC into a digital video recorder. Scheduling or one-click recording saves important images on your local hard disk, and the reliable motion detection and instant warning features make you ready for any situation. A quick and easy to use search and playback function lets you easily find the image you’re looking for, so that you can inspect the images more carefully, and also save the output to an AVI file.

To enable PTZ control, users should configure the PTZ control protocol in the web console.
NOTE
The PTZ control protocol is not standardized. To use a particular PTZ control protocol, the video encoder must support the driver for that protocol. Currently, the VPort 251 supports PTZ control protocol drivers for:
1. Pelco D
2. Pelco P
3. Dynacolor DynaDome
In addition, there is an item named “Transparent PTZ Control” in the camera driver list, which is to transmit the PTZ control signal via TCP/IP network to the VPort D251 video decoder or PC (additional Real COM driver required), and the PTZ control panel or keyboard can directly control the PTZ camera or device. In this way, there is no need for PTZ camera driver and better than that, you don’t have the protocol limitation for using PTZ camera with VPort encoders.
In addition, to use a protocol that is not on the list, you will need to contact the manufacturer of the camera to get the PTZ control commands, and then use the VPort 251’s custom camera function to program the PTZ control.
NOTE
The VPort 251 comes with a PTZ driver upload function for implementing new PTZ drivers. Please contact a Moxa sales representative if you need assistance from Moxa’s R&D department to create a new PTZ driver.

Wiring Requirements
ATTENTION
Be sure to disconnect the power cord before installing and/or wiring your Moxa VPort 251.
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.
You should also pay attention to the following:
y Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point. NOTE: Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.
y You can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
y Keep input wiring and output wiring separated. y It is strongly advised that you label wiring to all devices in the system when necessary.
Grounding the VPort 251
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.
Wiring the Relay Output
In this section, we will explain the meaning of the two contacts used to connect the Relay Contact.
The VPort 251 has one set of relay outputs, labeled RELAY 3 contacts on the 5-pin terminal block on the VPort’s top panel are used for the relay output.
The relay output can be configured for:
1. System alarm: such as for network disconnected.
2. Event alarm: such as for VMD (Video Motion Detection), video loss, and Digital Inputs.
2-14
VPort 251 User’s Manual Getting Started
ATTENTION
The maximum current and power capacity of the relay output is 24 VDC @ 1A. Please be careful not to exceed this power specification.
ATTENTION
Before connecting the VPort to the DC/AC power inputs, make sure the DC power source voltage is stable.
Wiring the Digital Inputs
The VPort 251 has one digital input channel, labeled DI. Two contacts on the 5-pin terminal block on the VPort’s top panel are used to connect to this DI.
STEP 1: Insert the negative (ground)/positive DI wires into the /I1 terminals.
STEP 2: To keep the DI wires from pulling
loose, use a small flat-blade screwdriver to tighten the connector.
STEP 3: Insert the plastic terminal block
connector prongs into the terminal block receptor, which is located on VPort 251’s top panel.
RS-232 Connection
The VPort 251 has one RS-232 (10-pin RJ45) console port, located on the top panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable (see the cable following wiring diagrams) to connect the VPort 251’s console port to your PC’s COM port. You may then use a console terminal program, such as Moxa PComm Terminal Emulator, to access the VPort 251’s console configuration utility.

The homepage of the VPort’s web console shows information specific to that VPort, the camera image, and configurations for client and server.
NOTE
The VPort’s web homepage is best viewed using a 1280 x 1024 screen size. This is because the camera image can be viewed at a resolution up to Full D1 (NTSC: 720 x 480; 720 x 576). We strongly recommend using IE 6.0 (Microsoft Internet Explorer) or above to avoid incompatibility with the ActiveX Plug-in.

Server Name
A server name can be assigned to each server. Administrators can change the name in System Configuration/System/General. The maximum length of the sever name is 40 bytes.
Camera Image View
The assigned image description and system date/time will be displayed in the caption above the image window. You may disable the caption or change the location of the image information from
the System Configuration/Video/Image Setting. Note that if the VPort’s motion detection
function is active, some windows in the video picture might be framed in red.
Audio Control
The VPort 251 provides both audio input and audio output for voice over IP communication. Client users can directly enable and disable the audio input (a microphone, for example) by clicking the microphone button, and audio output (a speaker, for example) by clicking the speaker
button from the VPort’s web homepage. You may also use the Client Setting to disable the audio
transmission.
Client Setting
Users can configure the following functions in Client Settings.
1. Media Options: Enable or disable the video or audio transmission.
2. Protocol Options: Choose one of four protocols to optimize your usage—UDP, TCP, HTTP,
or Multicast.
y UDP protocol can be used to produce audio and video streams that are more real-time. However,
some packets may be lost due to network burst traffic, and images may become blurred.
y TCP protocol can be used to prevent packet loss, which results in a more accurate video display.
The downside of using TCP is that the real-time effect is worse than with UDP protocol.
y HTTP protocol can be used to prevent being blocked by a routers firewall. The downside of
using HTTP is that the real-time effect is worse than with UDP protocol.
y Multicast protocol can be used to send a single video stream to multiple clients. In this case, a
lot of bandwidth can be saved since only one video stream is transmitted over the network. However, the network gateway (e.g., a switch) must support multicast protocol (e.g., IGMP snooping). Otherwise, the multicast video transmission will not be successful.
Once the video encoder is connected successfully, Protocol Options will indicate the selected protocol. The selected protocol will be recorded on the user’s PC, and will be used for the next connection.

RTSP Streaming
The VPort 251 supports standard RTSP (Real Time Streaming Protocol) streaming, which means that all devices and software that support RTSP can directly acquire and view the video images sent from VPort 251 without any proprietary codec or SDK installations. This makes network
system integration much more convenient. For different connection types, the access name is different. For UDP and TCP streams, the access name is udpStream. For HTTP streams, the access name is moxa-cgi/udpStream. For multicast streams, the access name is multicastStream. You can access the media through the following URL: rtsp://<IP address>:<RTSP
port>/<Access name> for software that supports RTSP.
Setting Description Default
RTSP Port
An RTSP port is similar to an HTTP port, which can enable the connection of video/audio streams by RTSP.

VPort 251 User’s Manual System Configuration
NOTE
The video performance of the VPort 251 in other media players may not always be the same. For example, you will notice a greater delay when viewing the VPort 251’s video from QuickTime player compared to viewing it directly from the VPort 251’s built-in web server. In addition, viewing the VPort 251’s video from Quicktime player through a router or Internet gateway could result in a broken connection.
NOTE
For the time being, the VPort 251’s RTSP video/audio stream can be identified and viewed by Apple QuickTime Ver. 6.5 and above, and VLC media player. System integrators can use these 2 media players to view the VPort 251’s video directly, without needing to use the VPort’s SDK to create customized software.
SMTP Server and Email Account Settings
The VPort not only plays the role of server, but can also connect to outside servers to send alarm messages and snapshots. If the administrator has set up some applications in either system information or alarm, the VPort will send out messages or snapshots once these conditions occur.

The system log will be sent to the Sender email address if the SMTP server settings are correct. To send the system log via FTP, the SMTP server should be erased since the E-mail system is used by default to transmit the system log.
NOTE
For either e-mail or FTP, the information of the 1st server should be entered first. If the 1st server is not set, the related FTP or email will be cancelled. Note that it may take time to connect to the 2nd server after the first server fails, and it may affect some applications when adverse conditions occur too often.
Dynamic DNS
DDNS (Dynamic Domain Name System) is a combination of DHCP, DNS, and client
registration. DDNS allows administrators to alias VPort’s dynamic IP address to a static hostname in any of the domains provided by the DDNS service providers listed on VPort’s Network/DDNS configuration page. DDNS makes it easier to access VPort from various locations on the Internet.

Multicast
The VPort 251 supports the advanced Multicast network protocol IGMP, which can greatly improve the efficiency of network traffic. In this section, we explain multicasts, multicast filtering, and how multicast can be implemented on your VPort.
What is Multicast?
A multicast is a packet that is intended for “one-to-many” and “many-to-many” communication. Users explicitly request to participate in the communication by joining an end-station to a specific multicast group. If the network is set up correctly, a multicast can only be sent to an end-station or a subset of end-stations on a LAN or VLAN that belong to the relevant multicast group. Multicast group members can be distributed across multiple subnetworks. Therefore, multicast transmissions can occur within a campus LAN or over a WAN. In addition, networks that support IP multicast send only one copy of the desired information across the network. The packets are only replicated if they reach a network node that links to two or more members of the multicast network. Transmitting packets in this way makes more efficient use of network bandwidth. A multicast packet is identified by the presence of a multicast group address in the destination address field of the packet’s IP header.
Benefits of Multicast
The benefits of using IP multicast are that it:
y Enables the simultaneous delivery of information to many receivers in the most efficient,
logical way.
y Reduces the load on the source (for example, a server) because it does not need to produce
multiple copies of the same data.
y Makes efficient use of network bandwidth and scales well as the number of participants or
collaborators expands.
y Works with other IP protocols and services, such as Quality of Service (QoS). y There are situations where a multicast approach is more logical and efficient than a unicast
approach. A typical use of multicasts is in video-conferencing, in which high volumes of traffic need to be sent to several end-stations simultaneously, but for which broadcasting that traffic to all end-stations would seriously reduce network performance. Besides, several industrial automation protocols, such as Allen-Bradley, EtherNet/IP, Siemens Profibus, and Foundation Fieldbus HSE (High Speed Ethernet), use the multicast approach. These industrial Ethernet protocols use publisher/subscriber communications models by multicasting packets that could flood a network with heavy traffic. IGMP provides the ability to prune multicast traffic so that it travels only to those end destinations that require the traffic, thus reducing the amount of traffic on the Ethernet LAN.

Accessible IP List
The VPort 251 uses an IP address-based filtering method to control access to the VPort.
Accessible IP Settings allow you to add or remove “Legal” remote host IP addresses to prevent unauthorized access. Access to the VPort is controlled by IP address. That is, if a host’s IP address is in the accessible IP table, then the host will be allowed access to the VPort. Administrators can allow one of the following cases by setting this parameter:
y Only one host with a specific IP address can access the VPort. Enter “IP
address/255.255.255.255” (e.g., 192.168.1.1/255.255.255.255)
y Hosts on a specific subnet can access the VPort. y Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”) y Any host can access the VPort. Disable this function.

SNMP
VPort supports three SNMP protocols. The available protocols are SNMP V1, SNMP V2c, and SNMP V3. SNMP V1 and SNMP V2c use a community string match for authentication, which means that SNMP servers access all objects with read-only or read/write permissions using the community string public/private (default value). SNMP V3, which requires you to select an authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to enhance data security. SNMP security modes and security levels supported by VPort are shown in the following table. Select one of these options to communicate between the SNMP agent and manager.

functions, which are also shown on the PTZ Control Panel . Administrators can click on Setup Custom Commands to configure the commands, and refer to the manual enclosed with the attached PTZ camera to set up frequently-used functions. The Command should be entered in
ASCII format. The VPort will translate the commands into binary code and then send the data out through the serial port. For instance, the text string 81 01ABCDEF will be translated into five bytes of hexadecimal: 81, 01, AB, CD, and EF. The maximum length of a command string is 60,
which is equivalent to 30 hexadecimal bytes. The Display string is for the text on the command buttons and should be less than 8 characters. If Custom Camera is selected, there will be more
commands for PTZF that relate to custom camera.

Step 2: Check on VMD1~3 to enable the VMD window. Left click the title bar of this window
to move the location of the VMD window, or drag the border to change the window size so that it fits the desired VMD area.
Step 3: Assign a name to the VMD window in the Window Name column. Step 4: Set up the Percentage parameters for individual VMD windows and the Sensitivity for
all VMD windows.
Step 5: Click on the Save button to save the settings. Step 6: To test the VMD condition, check the action of the graphics bar on the left side of the
save button. Wave your hand in front of the camera, in the VMD area, and then note which color shows up in the graphics bar. Green means VMD is not triggered. Red means VMD is triggered.
Step 7: Set up the Trigger Conditions and Actions of each VMD, and then click on the Save
button to save these configurations.
NOTE
Video Motion detection is provided as a reference because it is environment-dependent. When the settings are configured to be very sensitive to motion, some triggered events might actually be false alarms, since in fact there is only a tiny difference between sequential images. False alarms can be triggered by the flashing of florescent lights, shifting of shadows, etc.

Appendix A Frequently Asked Questions
Q: What if I forget my password?
A: Every access to the video encoder needs authentication, unless the admin password is set up as blank. If you are one of the managed users, you will need to ask the administrator for the password. If you are the administrator, there is no way to recover the admin password. The
only way to regain access to video encoder is to utilize the RESET button on the top panel
to restore the factory settings (see Chapter 1 for details).
Q: Why can’t I see video from the video encoder after it has been authenticated?
A: There are many possible scenarios:
1. If you have just installed the video encoder and are unable to see the video, check the
video modulation on the System Configuration\Video\Camera Modulation page.
2. If the video encoder is installed correctly and you are accessing the video encoder for
the first time using Internet Explorer, adjust the security level of Internet Explorer to allow installation of plug-ins.
3. If the problem still exists, the number of users accessing the video encoder at the same
time may exceed the maximum that the system allows.
Q: What is the plug-in for?
A: The plug-in provided by video encoder is used to display motion pictures. The plug-in is needed because Internet Explorer does not support streaming technology. If your system does not allow installation of plug-in software, the security level of the web browser may need to be lowered. It is recommended that you consult the network supervisor in your office before adjusting the security level.
Q: Why is the timestamp different from the system time of my PC or notebook?
A: The timestamp is based on the system time of the video encoder. It is maintained by an internal real-time clock, and automatically synchronizes with the time server if the video encoder is connected to the Internet and the function is enabled. Differences of several hours may result from the time zone setting.
Q: Why doesn’t the image refresh regularly?
A: This may be due to the time it takes to store recorded video and snapshots into memory, or the time it takes to send the images to the SMTP and FTP server when events occur.
VPort 251 User’s Manual Frequently Asked Questions
A-2
Q: How many users are allowed to access the video encoder at the same time?
A: Basically, there is no limitation. However the video quality also depends on the network bandwidth. To achieve the best effect, the video encoder will allow 10 users for udp/tcp/http connections and 10 users for multicast to be connected. We recommend using an additional web server that retrieves images from the video encoder periodically if you need to host a large number of users.
Q: What is the video encoder’s video rate?
A: The codecs can process 30 frames per second internally. However the total performance is subject to many coefficients, as listed below:
1. Network throughput.
2. Bandwidth share.
3. Number of users.
4. More complicated objects result in larger image files.
5. The level of your PC or notebook that is responsible for displaying images.
In general, the transfer rate for a general local network environment can achieve over 800 kilobytes per second and approximately 10 to 20 pictures of a normal environment per second.
Q: How can I keep the video encoder as private as possible?
A: The video encoder is designed for surveillance purposes and has many flexible interfaces. The user authentication and special confirmation when installing can keep the video encoder from unauthorized access. You may also change the HTTP port to a non-public number. Check the system log to examine any abnormal activities and trace the origins.
Q: I have a PTZ camera that is not on the support list. How can I control it?
A: The video encoder provides a custom camera command interface to control cameras that are not supported. The details are described in this manual. Be sure that the PTZ port settings are applied to the camera specifications. The general PTZ command is composed of one start command and one stop command. When editing both commands in the edit box of the configuration page, use comma(s) to separate commands. Each comma represents 200 milliseconds. In addition, the VPort has a PTZ driver upload function. Users can also seek help from Moxa to create a new PTZ driver.
Q: How fast will the video encoder check the status of digital inputs?
A: The video encoder will check the input status in less than half a second.
Q: Why can’t I access the video encoder when I set up some options in the application?
A: When the video encoder is triggered by events, video and snapshots will take more time to write to memory. If the events occur too often, the system will always be busy storing video and images. We recommend using sequential mode or an external recorder program to record motion pictures if the event is frequent. If you prefer to retrieve images by FTP, the value could be smaller since an FTP server responds more quickly than a web server. Once the system is too busy to configure, use the restore factory default and reset button to save the system.
Q: The image is not clear enough. Is anything broken?
A: The lens can be focused by rotating the outer ring. Rotate it clockwise or counter-clockwise to focus near or far.
