CHAPTER 1 Introduction

For the first time, VIP realizes live video transmission via existing computer networks. Efficient compression, according to the ITU-T standard H.261, enables video communication over virtually any TCP/IP connection: local area networks as well as the Internet (wide area network).

Simply configure an IP address using a standard terminal program or any Internet Browser and connect required.

VIP to the Ethernet. That’s all the installation

This chapter will familiarize you with the underlying concept of the timedia gateway, will provide an overview of the features and will give examples of typical applications. After an introduction to the front and back panel connectors, you are in a good positi on to follow the ins tallation and configuration details given in the succeeding chapters.

Multimedia Gateway Concept

Continuous media such as video and audio are meant to be transported over dedicated lines, for example coaxial cables. With computer networks becoming ubiquitous and unde r the umbrella of the Internet, there is a trend to integrate all sorts of data types into computer networks. This trend is driven by the request for a single network, yielding significant savings in reduced costs and simpler installation and management of a single network.

The VIP multimedia gateway was designed, to integrate multimedia data streams into computer networks based on Ethernet and the TCP/IP protocol suite. of-use, enabling you to transmit full color live video with accompanying full-duplex audio and data over standard Ethernet-type networks.

VIP combines state-of-the art compression technology with ease-

VIP comes in two flavors, as a VIP - VTx sender or as a VIP - VRx receiver.

The sender will connect any PAL or NTSC video source to the computer network. Conversely, the receiver will display the video on any standard PAL or NTSC monitor. Alternatively, video is received via the software decoder (see separate datasheet) on any PC in the network. Remote control of peripheral components like pan/tilt/zoom cameras is facilitated by the bidirectional serial interface. Transmission of full duplex audio is an option.

From the user’s perspective, video sources such as cameras, are identified by IP addresses, just like any other equipment connected to a computer network. As shown in Figure 1, there are 3 choices for display of remote video streams:

• Web Br owser using any PC on the network

•

VIP -SW1 or VIP -SW1 software application

•

VIP - VRx hardware receiver and attached moni tor

VIP -SW1 or VIP -SW1

Typical Applications

VIP provides a s et of advanced feat ur es for r emot e video surv eill ance and

security: the integrated motion video sensor will setup a connection autonomously when motion in the scene is detected. Pre-alarm history is stored in a video ring buffer for alarm verification:

• Video surveillance of rooms and buildings

• Remote maintenance of machinery

• Facility managem ent and facility security

Features and Benefits

VIP is a flexible, high- pe rformance, eas y -to-use device that provides a

Step 4: Selecting an IP Address for Your Network

VIP comes with the default IP address of 192.168.0.1. Before operating

the system inside your own network, a valid IP address needs to be set. offers 3 convenient ways for configuring IP addresses:

1. Using command line tools, e.g. in a DOS box.

2. Using a terminal program attached at the RS -232 control terminal port.

3. Using a Web Browser.

In the following, IP ad d res s co n f ig ur ati o n us in g comm and line tools is described in detail. For a description of IP address configuration using a terminal program or a Web Browser refer to chapter 4.

The command line procedure for configuration of an IP address requires the

VIP to be located in the same subnet as the configuring PC. Two steps

are required:

1. Add MAC-address to the PC’s ARP routing table:

You first have to make the VIP known to the ARP routing table of the PC, which you are using for the configuration. The ARP routing table links the hardware or so-ca lled MAC address to the IP address to be configured. The MAC address of the unit can be found on the bottom label of the unit. At the command line, in a DOS box, type the following:

VIP

C:\>arp -s "IP address" "MAC address"

For example, the command line

C:\>arp -s 192.168.0.5 00-60-54-04-F5-94

will link the IP address 192.168.0.5, which is the one to be configured, to the unit’s MAC address 00-60-54-04-F5-94. The command will add an entry into your PC's ARP table. Check the new entry by typing:

C:\>arp -a

The entry should appear in the displayed list. It is possible, however , that the PC will not add a new entry into an otherwise empty table. In this case, just ’ping’ any other PC or network device and try again.

2. Assign the IP address using the ’ping’ command:

Step 1 above was required in order to reach the VIP unit to be configured. The actual configuration of the unit is carried out using the ’ping’ command. By typing

C:\>ping "IP address"

the PC system will send a message (ICMP) to the the attached IP address and will con figu re itsel f acco rd in gl y. At lea s t one positive reply should appear on the PC screen. If there are no replies, the

VIP unit is not connected properly or is not located in the same subnet as

your PC. In this case you either have to use another way to configure the IP address or reconfigure the network arrangement.

Connecting Video Sources or Displays

For connecting a camera to the VIP - VTx transmitter, use a standard

coaxial cable and plug it into the BNC connector at the front panel of the

VIP - VTx. Any camera or other video source, e.g. a VCR with a composite

PAL or NTSC output can be connected. The input accepts color or B&W

sources and automatically detects the standard (PAL or NTSC). When using

VCRs as input source the video quality can be improved by setting the

Input Source in the Video Configuration Page (see chapter 4) to VCR. The

video input is equipped with an internal termination with 75 Ohms.

Figure 8. Pin Assignment of the Handset RJ-11 receptable

A handset can be connected to the RJ11 receptacle labelled Handset at the front panel of the radio button labelled Handset in the Audio Configuration Page.

The input and output level ranging from 0...100% can also be set in this configuration menu. Moreover, the coding mode at the sending side can be set using the menu item Coding mode between two different modes or switched off.

The audio decoder will a utomatically follow the selected audio coding of the transmitter. In cases where the receiver is not capable of decoding the selected mode, e.g . sof tw a re de co d er, an automatic so-called fall-back to the next available audio mode occurs.

The second audio channel is available at the two cinch receptacles labelled Audio In and Audio Out at the front panel of the this channel the radio button Line In/Out in the Audio Co n f ig ur ati on Page has to be selected. The level and coding mode settings apply to this channel in the same manner as describ ed above for the first channel.

Connecting Data Terminals

VIP features two serial interfaces, at the front and the back pane l respec-

tively. They serve different purposes and cannot be used interchangeably,

as is explained in the fol lo win g :

Terminal Port

For local control and configuration of the VIP unit a data terminal (e.g. a

PC running a standard terminal program) can be connected to the serial

interface labelled Control Terminal on the rear panel. The 9-pin DSUB con-

nector feature s a stand ard RS -232 int erface that can be connecte d to any

PC’s COM-port.

A standard terminal program may be used to communicate with the

The default parameters are set to 19200 baud with 8 bits of data, one stop

bit and no parity bit (8N1).

An online help function can be evoked by typing ’?’ in the terminal win-

dow. For more information on the command set refer to chapter 4.

VIP.

Tra n sparent Data Port

The second serial interface on the front panel of the VIP offers a transpa-

rent serial data channel between the receiver (e.g. COM-port of a PC)

and the

channel are remote control of peripheral equipment, e.g. pan/tilt/zoom

facilities of selected cameras. In addition this channel can be used for

remote control of any external device with a serial interface. The serial

data is transferred in parallel to the video and audio data.

Note that transmission of transparent data is enabled only after a video

connection has been established. Also note that the RS-232 interface for

the transparent data port does not support hardware flow control.

Connecting External Sensors and Controlling Peripheral Devices

VIP is equipped with an alarm input to be used for external signalling

devices, like door contacts or motion detectors. Switches or contacts can be connected directly without a separate power supply. The signalling input is located on the two left pins of the detachable screw terminal (see Figure 9).

1 3

Key: 1 = Alarm Input, positive terminal 2 = Alarm Input, ground terminal 3 = Relay Output, Y 4 = Relay Output, Z

Figure 9. Pin Assignment of the I/ O Con n ector

The input is activated by connecting pin1 to pin 2. Triggering of an alarm may be configured to occur upon closing (=active high) or openi ng (=active low) the contact between pin 1 and pin 2. Also, alarm action, e.g. connecting to an alarm IP address or sending an alarm email, can be configured. Refer to chapter 4 for a discussion of the p o ssibilities.

The relay output may be operated interactively, during an active connection, or automatically to coincide with certain events. Again, configuration items include comprehensive settings of the switching behavior of the relay (chapter 4).

Typical applications of the relay output are the activation of electric door openers or the switching of lights and othe r electrical devices. Do not exceed the maximum rating of 24V/0.5A.

CHAPTER 4 Configuration

Two possibilities exist for configuration:

• Most basic control and configuration is obtained by connecting a terminal to the RS-232 terminal port.

• Most comfortable configuration and display of video is fac ilitated by the built-in HTTP server, which connects to any standard Web Browser.

Configuration using a Terminal

Using a terminal program connected to the RS-232 terminal port at the rear panel of the bilities. Ensure that the COM port of the used PC is set up properly (default parameters are 19200 ba ud, 8N1) and that the local terminal echo is disabled.

All commands consists of single characters, which are typed inside the terminal window. The following section shows a typical terminal session:

VIP unit will allow for limited configuration and control capa-

Typical Session

Typing a question mark ’?’ will prompt the VIP unit to output the help screen on the terminal window:

******************************************* Help menu '?' this site 'i' set the IP address 's' set the subnet mask 'g' set the gateway IP address 'a' set the alarm IP 'c' connect to alarm IP 'd' disconnect 'm' display MAC address 'v' display version information 't' toggle DCHP On/Off

disable 'local echo' for a better display ! *******************************************

If you are using the terminal to set up the unit's IP address, just type 'i' and you are prompted to enter a new IP address:

->Enter new IP address (old:192.168.0.1): 192.168.0.5

[Enter]

->IP address set to 192.168.0.5

Note: There are no backspaces allowed during a terminal session; if you have mistyped a character, just terminate your entry by pressing [Enter] and try again. If you see duplicate characters on entry, the 'loca l ech o' feature of your PC's terminal program is not disabled.

If you want to establish a live video connection to a remote

VIP or VIP -

SW1, you have to specify the remote IP address by typing 'a' and entering

the remote IP address in the same manner as the unit IP above.

Configuration 25

In order to establish a connection type 'c', to disconnect 'd'. Be sure not to connect two units of the same type, e.g. receiver to receiver. Likewise, a connection between a

VIP - VRx receiver and a VIP -SW1 software

decoder does not make sense.

camera name may be stamped into the video frame. There is a choice of upper or lower left hand corner for display of the name information inside the video frame.

Time stamping off T S imilar to the name stamping, date

and time information may be stamped into the live video frame at either the upper or lower right hand corner. Note that the stamping takes place at the transmitter before the actual coding takes place. Therefore the name and the date/time information are an integral part of the coded and transmitted data stream.

detection feature. The video scene is constantly monitored for relevant motion.

The sensitivity needs to be adapted to the respective environment and the acceptable false alarm rate: for a lower false alarm rate select a lower sensitivity and vice versa. Some experimentation is required to find the best setting. The use of the motion detection feature is only recommended indoors and under controlled lighting conditions.

For advance settings, for example masking regions of interest inside the video frame, interworking with a software decoder such as

Alarm input pin off If external sensors or simple contacts or

switches are to be used in combination with

VIP, the alarm input needs to be

selected. In addition the polarity of the signal may be changed from active high to active low. For example, depending on the configuration, an alarm may be triggered when a contact opens or closes.

VIP -SW1 is required.

Alarm status off Current alarm activation status can be

displayed via on-screen display, similar to the name, date and time stamping, discussed above.

If configured to be on, the status of the activated alarms, namely video, motion and input, is depicted in the upper left hand corner of the video frame. Alternatively, the display may be activated as soon as an alarm condition is reached. This way, the video frame corresponding to the alarm condition is clearly marked.

Furthermore there is a choice to keep the status display, once an alarm has been triggered, even when the original cause of the alarm is no longer present, or to have the status display follow the alarm condition.

Alarm message string empty In connection with the alarm status

explained above, a user defined text string may be displayed on screen in the upper right hand corner. The text string is typically used to convey additional alarm related information to the remote viewer, i.e. the guardsman for example.

Once all addresses are configured, the actual connection is established by typing 'c' in the terminal window. Make sure that the alarm IP address in the unit which is used to initiate the connection points to the destination unit. After a few seconds, video transmission commences and the camera scene is displayed on the monitor attached to the receiver .

As an alternative to using a terminal program for connection establishment you may attach a contact to the alarm input. Make sure that the alarm input is enabled. Note: It is not possible to initiate a connection betwee n

VIP units by using a Web Browser.

You may use a Web Browser to connect to any one of the two units, even during an active hardware-to-hardware connection. This way you can make changes to the configuration and immediately watch the result of the setting, for example when changing video quality. If you are connected to the transmitter, the camera picture is transmitted to the receiver and to the Web Browser simultaneously. You will experience a short break in the display of the video on the receiver monitor, whenever the Web

For

VIP units equipped with the audio option, full duplex audio may be

transmitted in parallel to the video transmission. To this end audio needs to be enabled on the audio settings page, using the Web Browser.

Transparent data is always automatically transmitted between the two units as soon as the connection becomes active. Data bytes entering the interface are transparently transported to the other end. Note that no flow control mechanism is in effect for the data channel. Overflowing the serial interface will lead to data loss.

The connection may be disconnected from either end by typing 'd' in the respective terminal window.

Up to four audiovisual data str eams, stemming from four different sending units, which may even be communicated across different networks, may be simultaneously decoded and displayed in real-time. The achieved picture quality and frame rate will satisfy even the highest demands. The graphical user interface adopts the popular Internet Browser style, yielding intuitive operation.

VIP -SW1 is fully compliant to the international ITU-T

VIP -SW1 communicates across wide area networks (WAN) like ISDN (Inte-

grated Services Digital Network), analog telephone lines (via modem) and wireless GSM networks as well as local area networks (LAN). LAN connection of remote video sending units is especially attractive for cost efficient realization of facility management systems, based on existing structured cabling.

In addition to the display of live video, audio is played-back over the optional sound card of the PC system. Received media streams, comprising video, still pictures and audio, may be recorded to harddisk. Archived data can be retrieved at any time for display, analysis, reporting and printout.

VIP -SW1 provides full remote control of these systems including attached

peripheral components as pan/tilt/zoom-cameras, for example. Wherever

CHAPTER 6 Advanced Features

Apart from the superb video quality and the ease-of-us e VIP does also sport some advanced fea tures described in the following.

Automatic Connection Feature

The advantage of conventional dedicated cabling lies in performance guarantee and availability. The auto-connect feature has been designed especially in order to provide the same level of guaranteed connectivity we come to expect from analog coaxial video cables.

It is not uncommon for IT-networks to experience short breakdowns or congestions. The protocols employed for computer communication, for example TCP/IP, have been designed to cope with missing data and interruptions. For video stream would normally terminate gracefully when a network connector is pulled or the network is otherwise disrupted.

VIP, once a video connection has been established, the

In order to guarantee connectivity, cally reconnect. In order to activate this feature, just click the Auto-Connect radio button to On and confirm this choice by clicking the Set button. From this point on, the unit will try to connect to the specified alarm IP address every time. The receiving st ation (alarm IP address) can either be another

VIP - VRx unit or a PC running VIP -SW1.

Video Motion Detection Feature

The VIP - VTx transmitter has the ability to autonomously check the video input for significant motion in the scene and to trigger an alarm in case the detected motion exceeds a preset threshold. Motion detection is switched on by setting Motion Alarm to On in the Alarm Configuration Menu.

The sensitivity of the motio n de tec to r can be sele cte d in the sam e m enu . This parameter needs to be adapted to the requirements of the particular application. The best setting should be determined experimentally. Note that higher sensitivity will result in a lower robustness against noise and spurious motion in the scen e. This may lead to unwanted erroneous detections and consequently increase the rate of fals e al arms.

VIP may be configured to automati-

Motion detection can be restricted to certain areas in the scene. Up to 242 square regions can be i n dividually selected in or der to mask specific parts of the scene. For more detail on that feature refer to the

When using a Web Browser no speci fi c reg io ns can be selected, only the motion alarm can be turned on or off and the sensitivity can be set to different values.

Alarm Notification by Email

The email feature allo w s to send an em ail me ss ag e to a recip ien t o n any alarm event. This could be used to signal an alarm to persons not being attainable by a video based notification. To activate this feature, enable at least one of the alarm inputs, configure a receiver email address and enable the send email button. Don't forget to configure a mail server and gateway IP addresses in the general settings page.

Firmware Upload

From this point on, the

VIP will send an email to the specified recipient on

every alarm event. There will be a timeout for at least 30 seconds before a new mail message is generated on the same alarm event.

The mail will contain the status of the three alarm inputs, so you can determine which event triggered the mail, when more than one alarm input is enabled. A JPEG-encoded video snapshot is attached to every alarm email message. The snapshot is taken precisely at the time of the alarm event, there by documenting the condition.

The VIP units are equipped wi th Fl as h EPR OM s for f irmware upgr ad ability while the units are in the field. Firmware upload is accomplished either directly from the Web Browser or using the standard FTP protocol.

Firmware upload using the Web browser is accomplished as follows:

1. Obtain the latest version of the VIP firmware from the Internet (http://

www.Hirschmann.com).

2. Using the Browser select the page General Settings of your VIP unit.

3. Select the correct new firmware file using the ’Browse’ button.

4. Activate the button ’Upload’.

10. Now VIP is busy uncompress ing the uploaded file and reprogramming

the Flash EPROM. The green LED should blink rapidly to indicate this type of activity.

Do NOT power off now! Interrupting the upload and reprogramming cycle will damage the Flash EPROM. The unit needs to be send in for repair.

Once reprogramming is complete, the green LED will stop blinking.

11. Due to the unit's reprogramming and resetting, the FTP connection to

the PC is no longer active - Press [Ctrl]+break to terminate the FTP session.

Advanced Features 51

Dynamic Allocation of an IP Address using the DHCP Protocol

If an DHCP server is active installed in your network, the VIP DHCP protocol may be used for automatic allocation of an IP address. Every time the is powered up, a valid IP address is assigned by the DHCP server. Using the DHCP protocol is especially useful in larger networks, where tracking down a free IP address may be tedious. Whenever a new IP address has been assigned, a message is output over the terminal port.

Regardless of the method of configuration, either manually or automatically via DHCP protocol, in cases whe re you are unsur e about the assi gned IP address, you may experience difficulties reaching the unit via Web Browser. Use a terminal program to determine the configured IP address.

VIP answer when you

To find ou t if a VIP is reachable in your network, try to ping your unit by typing the following command in a DOS box.

c:\>ping “VideoJet IP address”

If it is reachable there will be a response like the following:

Reply from <IP address>: bytes=32 time=NN ms TTL=xxx

If the LAN path is not functioning correctly, the ping command will time out. In that case you could have one of the following problems:

• Wrong physical connections : Ma ke su re the LA N Link LED is o n . For

more information on this item see the section above.

• Wrong network configuration: Verify that the IP address is entered cor-

• Connect a microphone (via a pre-amplifier) to the Line-In cinch plug and a loudspeaker to the Line-Out cinch connectors, respectively, or a handset to the RJ11 plug on both units.

• Make sure that the correct menu items are set in the Audio Configuration pages of both systems, i.e. select the appropriate interface (line I/O or handset).

• Switch the coding mode to G.711 or G.728.

• Select a non zero volume.

• After establishing the Ethernet connection audio should be transmit-

ted in both ways.

• Be sure to set the level not too low and to have the right interface selected.

• In case no audio is audibl e check the microphone and loudspe aker together with other audio equipment and make sure the microphone is switched on if it is equipped with a power switch.

Restoring the Default Configuration

In case the user wants to restore the factory default configuration, VIP features a special HTML page which has to be opened to execute the configuration reset. For this purpose enter the IP address of the unit in the Web Browser followed by “ /reset“. Opening this page will reset the nonvolatile configuration memory to the factory defaults.

Example:

http://192.168.0.5/reset

Attention: This action will also reset the IP address of the value! This means, that after this command, the Web Browser will lose the connection to the unit. Be careful using this command, because any configuration, like IP address, subnet mask, camer a name and many other settings will be erased and reset to the default value s!
