Product description Preconditions for operation Computer with operating system Windows 95/98/NT and a gateway to the network Microsoft Internet Explorer web browser (from Version 5) or VCS software decoder e.g. PROVILook or Receiver VideoJet and video monitor Overview of functions Network video server The is a network video server. It serves primarily for encoding and decoding video, audio and control data for transfer via an Ethernet LAN. By using existing networks, the VideoJet permits the simple installation and configuration of CCTV systems. The is available in two versions, as a desktop device with separate plug-in power pack and in a control cabinet version with integral power pack. Whereas the desktop device is available as a data server only for transmission of data, transmitting and receiving of data are possible with the control cabinet version. Two VideoJet devices, e.g. a as transmitter and a VideoJet receiver, can form a stand-alone System for data transfer without PC. The system can be extended to include further transmitters and receivers so that video sequences from one transmitter can be received by several receivers simultaneously. Receiver The corresponding VideoJet devices or computers with installed decoding software, for example PROVILook from VCS, or with installed Microsoft Internet Explorer can always be used as receivers. 14
Product description Multicast function The supports the standard H.323 and is thus compatible with all video-conferencing systems. Thanks to efficient encoding, the data transmission rate remains low, even with maximum image quality and 30 images/s; furthermore, it can be adapted over a wide range to meet the local requirements. In appropriately configured networks, the multicast function permits the simultaneous video transmission in real time to several receivers. A precondition for this is the implementation of the UDP (User Datagram Protocol) in the network. Integral multiplexer The is designed for the connection of four freely selectable video sources (PAL or NTSC). With the appropriate software on the receiver side, e.g. PROVILook from VCS or the Microsoft Internet Explorer, four camera images can be viewed simultaneously in this way. Remote control For remote control of external equipment, e.g. pan-and-tilt heads for cameras or motorised zoom lenses, the control data are transmitted via the bidirectional serial interface of the. This interface can also be used for the transmission of transparent data. Configuration The can be configured with a browser via the local network (intranet) or via the internet. Firmware updates and the quick uploading of device configurations are possible in the same way. 15
Product description Summary The offers the following main functions: Video, audio and data transmission via data networks. Multicast function for simultaneous image transmission to several receivers 4 video channels (PAL and NTSC compatible), transmission of the video images as high-resolution individual frames, image sequences or with quad split High colour image resolution with 704 576 pixels and up to 30 images/s One audio input, one audio output Video transmission compatible with international standards H.323, H.261/263 and M-JPEG Integral Ethernet interface (10/100 Base-T) Transparent bidirectional data channel via serial interface RS232/RS422/RS485 Remote control of all internal functions via UDP/IP Password protection to prevent unauthorised access Switching inputs for external sensors (e.g. door contacts) Switching outputs for switching external devices (e.g. lights or sirens) Event-controlled automatic connection setup (e.g. when switching on and at alarms) Integral video sensor for motion alarms Video signal monitoring Automatic transmission of alarm e-mails with attached image Video ring memory for recording of alarm pre-histories Quick and convenient configuration via web browser Firmware update via flash memory 16

Installation 4 Thanks to its compact design, the as desktop device requires a minimum of space. Attention! The server is designed for operation indoors. Choose a site for installation which ensures that the server is exposed to neither extreme temperatures nor extreme moisture or humidity. The ambient temperature must lie between +5 and +40 C, the relative humidity must not exceed 80%. During operation, the server generates a great deal of heat. Therefore ensure sufficient ventilation and an adequate distance to heatsensitive equipment or objects. Please observe the following installation conditions: Do not install the VideoJet in the immediate vicinity of radiators or other sources of heat. Avoid installing the VideoJet where it is exposed to direct sunlight. Ensure sufficient space for laying the cables. Ensure adequate ventilation of the VideoJet. In particular, observe the heat burden when installing several devices in the same control cabinet. For all cable connections, use only the supplied or suitable cables which also prevent any electrical interference, where necessary. Lay and install all cables in such a way that they cannot be damaged and ensure sufficient strain relief. 21
Installation Cabinet installation The control cabinet version of the is designed for installation in standard 19" slots. The device has an integral power pack and is supplied with two mounting brackets on the side for installation. Attention! During control cabinet installation, ensure adequate ventilation of the : There must be a clearance to the left and right of the device of at least 5 cm and at least 10 cm to the rear. The ambient temperature must lie between +5 and +40 C, the relative humidity must not exceed 80%. The VideoJet gives off heat during operation. Therefore ensure adequate ventilation and a sufficient distance from other heatsensitive equipment or objects. When installing other equipment, direct contact with the VideoJet is permitted if the surface temperature of the neighbouring equipment does not exceed +40 C. If necessary, screw both brackets to the housing of the. Place the into the control cabinet and secure it with four screws. Insert the power lead supplied into the mains socket on the rear of the device. 22
Installation Connections Cameras A maximum of four video sources can be connected to the. Suitable devices are all cameras and other video sources which generate a PAL or NTSC standard signal. The control cabinet version of the also has a monitor output which permits the connection of a monitor suitable for PAL or NTSC standard video signals if the device is also to be used as a receiver. Connect the cameras or other video sources to the BNC jacks VIDEO 1 to VIDEO 4 using a video cable (75 Ohm, BNC connector). Set the DIP switches to position 75 OHM ON (down) to terminate the inputs at which the video signal is not lopped through (e.g. with a T-piece). If necessary, connect a video monitor to the BNC jack VIDEO OUT of the control cabinet device using a video cable (75 Ohm, BNC connector). Network connection You can connect the either directly or via a hub to a 10/100 BASE-T network. Use a standard cable UTP Category 5 with RJ45 connectors for this connection. Connect the network cable to the ETHERNET jack. Alarm inputs The four metallically isolated alarm inputs serve for the connection of external alarm triggers, e.g. door contacts or sensors. If configured accordingly, an alarm trigger can, for example, set up an automatic connection between VideoJet and the remote station. Connection INPUT 5 serves as a master alarm. If necessary, this contact allows all the alarm triggers (contacts and video sensors) to be activated or barred, e.g. by means of a key-operated switch. 23
Installation All four alarm inputs are metallically isolated from the other components of the via optocouplers and require a DC voltage of 5 to 12 V for switching. Attention! On no account should the external switching voltage be connected to the housing earth of the. The external switching voltage must not exceed 12 V. If a metallic isolation is not required, the operating voltage of the is alternatively available at the input marked +5V (up to max. 5 ma). If necessary, a floating NO contact or push-button can be connected to this input. If a floating NO contact is used, the contact +5V must be connected to the corresponding INPUT connection. The signal generator is then connected between the other contact of the INPUT connection and the contact GND. Note If possible, use a bounce-free push-button as signal generator. Pull terminal block INPUTS from its plug-in base. Lay the conductors to the terminals and then check that all screws are securely tightened. Push the terminal block onto the plug-in base again. 24
Installation Control outputs The has four relay outputs for switching external devices, e.g. lights or alarm sirens. These control outputs can be used interactively during an active connection with the. Furthermore with appropriate configuration, the control output can activate, for example, an alarm siren in response to an alarm signal. Attention! The relay contacts must not be subjected to a burden of more than 40 V and 0.8 A. Pull terminal block OUTPUTS from its plug-in base. Lay the conductors to the terminals and then check that all screws are securely tightened. Push the terminal block onto the plug-in base again. Audio connection The provides an audio channel via the jacks AUDIO IN and OUT. The audio signals are transmitted bidirectionally and simultaneously with the video signals. This allows, for example, a loudspeaker or door intercom system at the surveillance location to be controlled. Connect the microphone to the jack AUDIO IN. Connect the loudspeaker to the jack AUDIO OUT. Data interface The bidirectional data interface serves to control a device connected to the, e.g. a dome camera with motorised lens. The 9-pin sub-d jack COM is provided for this connection. The range of devices with can be controlled is being constantly expanded. Information on installation and device control can be can be obtained from the supplier of the controlled device. 25
Installation Attention! When installing and operating the device to be controlled, observe the corresponding documentation. It contains important safety notes and information on permissible applications. Note The transmission of transparent data is only possible when a video connection has been made. 26
Installation Switching on / Switching off Mains connection The scope of supply of the in the desktop version includes a plug-in power pack. The control cabinet version of the has an integral power pack. Attention! Use only the plug-in power supply unit supplied for operation of the. Take appropriate measures or install the appropriate equipment to prevent surge voltages, interference voltage peaks or power failures in the mains supply from reaching the server. Connect the to the mains power supply only when all the other connections have been made. The has no mains power switch. When you have connected the plug-in power supply unit to the and inserted the plug of the plug-in power supply unit into a plug socket, the server is ready for operation. Push the plug of the power supply unit cable into the jack POWER until it latches. Plug the plug-in power supply unit into a fused mains power plug socket. The green LED POWER on the front of the VideoJet 400 lights up and the server is ready for operation. When the network connection has been correctly made, the green LED ETHERNET also lights up. The flashing yellow LED signals the transport of data packages via the network. 27
Installation Commissioning with terminal program Data terminal You can connect a data terminal to the for putting the unit into operation and for the local control. The data terminal consists of a computer with a terminal program. For the connection use a serial standard cable. You can use e.g. the Windows application HyperTerminal as terminal program. Note Information on the installation and use of HyperTerminal can be found in the documentation or in the online Help for Windows. First, disconnect the from the network. Connect the sub-d jack COM of the to a free serial port of the computer. Configuring the terminal program The transmission parameters have to match for communication between terminal program and VideoJet. Set the following values for the terminal program: 19,200 bits/s 8 data bits No parity check 1 stop bit Protocol Xon/Xoff 28

Or select On alarm hold if the alarm source is to continue to be displayed even after the end of the alarm status or until it is confirmed. 39
Configuration with web browser Video settings Video configuration Picture quality: You can set the quality of the video reproduction. A compromise has to be found here between optimum image sharpness and a quick reproduction of movements in the image. If you attach importance to a high image refresh rate, the quality of the image (sharpness) deteriorates with increasing movement in the field of view of the camera (unsharp, distortions). If you prefer sharp and clear images, this results in a reduction in the frame rate in the event of movements in the image. If movements are only to be expected in a small area of the image, you can give preference to the sharpness. The intelligent compression process is then able to refresh the areas of the image concerned in the case of spatially limited movements. The unchanged rest of the image will be reproduced with the optimum sharpness. With high bandwidths in the local network (above 200 kbit/s), you can work with maximum picture quality without the refresh rate decreasing noticeably. 40
Configuration with web browser Resolution: You can choose between high (CIF) and low (QCIF) video resolution. The Common Intermediate Format (CIF) supports a local resolution of 288 lines 352 pixels. This is the resolution used in the standard setting. The format Quarter CIF (QCIF) offers the resolution 144 lines 176 pixels. Choice of the lower resolution can be expedient if you give preference to a high frame rate over a high video resolution. Output standard: Here you can select the video standard for the monitor output (PAL or NTSC) for the control cabinet version which is also used as a receiver. Max. transmit bandwith: Here you can define the maximum limit for the transmission rate and the data rate for the ActiveX receivers of your browser on the transmitter side. This value relates only to the video transmission rate (without audio and protocol). The receivers can log into the transmitter with a lower or with the same data rate. In streaming mode, this value indicates the data transmission rate of the streamed video. Select a video transmission rate between 10 kbit/s and 1 Mbit/s. Video on Start Page Enable JPEG or ActiveX: You have the possibility to choose whether live pictures are displayed by JPEG server push (MJPEG) or by the installed ActiveX control (ActiveX live video). Note If the ActiveX control is not installed on your computer, a corresponding message will be displayed when you switch to the live image page. The latest version of the ActiveX control is available from your VCS service centre. 41
Configuration with web browser JPEG settings You can store video images in JPEG format at certain intervals on an FTP server. These images can be called up again later, thus enabling for example alarm events to be reconstructed. JPEG posting time slice: Enter the time interval here at which the single images are to be sent. Enter zero, if no single images are to be sent. FTP server IP address: Enter here the IP address of the FTP server on which the images are to be stored. Login name: Enter your login name for den FTP server here. Password: Enter the password for the access to the FTP server here. Path on server: Enter the exact path here under which the images are to be stored on the FTP server. 42
Configuration with web browser Audio settings Audio level Here you can set the sensitivity of the input and output for audio signals. Match the configuration settings to the interfaced devices in order to avoid overmodulation and the consequent distortions. Information on this can be found in the documentation on the devices used. Input: Enter the sensitivity of the audio input here. Output: Enter the sensitivity of the audio output here. Audio coding Coding mode: You can select the coding mode for audio data. Mode G.711 supports all systems. Select G.711 (3.5 khz, 80 kbit/s) to select the corresponding coding mode or select Off to work without coding. 43
Configuration with web browser Alarm settings On this page you can configure the behaviour of the in the event of an alarm and the alarm triggering events. Alarm Sources You can select and activate the sources for alarms. In the event of an alarm, the symbol corresponding to the alarm source is displayed white in the video image. Video loss alarm: The input signal from the camera is monitored. If no signal is received, the triggers the alarm. Motion alarm: The has an integrated video sensor which is able to record changes in the video signal on the basis of image processing. These changes are mainly initiated by motion in the field of vision of the camera. The sensitivity of the video sensor can be adjusted so that an alarm is only triggered after exceeding a preset threshold. Select On to trigger an alarm in the event of movements. Select Off if you do not wish to permit a motion alarm. 44
Configuration with web browser Motion Detection You can select the image areas to be monitored by the video sensor. The video image is divided into 242 square cells. You can activate or deactivate every one of these cells. For example, if you want to exclude certain areas in the field of vision of a camera from the monitoring because there's continuous motion in that area (trees in the wind), deactivate the corresponding cells. In order for the video sensor to function, the following conditions must be satisfied: The motion detection must be activated. At least one cell must be activated. The sensitivity must be set to a value greater than zero. The master alarm may also have to be activated. Attention! The basis for the video sensor is always the video image displayed on the live image page. You therefore do not need to switch over the image after activating the video sensor (another camera or quad split), as the complete change of the image content would immediately trigger the alarm. Light reflections (e.g. in glass facades) or changes in light due to individual clouds in bright daylight can result in undesirable reactions of the video sensor and thus in false alarms. Carry out sufficient tests to ensure the correct function of the video sensor. For surveillance of indoor areas, ensure a constant lighting of the areas during the day and at night. Click on the button Configuration to open the window for configuration of the video sensor. Click with the left-hand mouse key in the cells you wish to activate.

Alarm input 5 (Master): It is possible to use the alarm input 5 as master alarm, for example if a key switch is used for making the system alert. If this option is activated, the alarm input 5 must be active in order to enable all other alarms. Camera follows alarm input: When an alarm is triggered, the can switch over automatically to the input of the corresponding camera. Select On if the image of the corresponding camera is to be displayed in the event of an alarm, or Off if the current camera selection is to be retained. 46
Configuration with web browser Connections on Alarm You have the possibility of setting the behaviour of the VideoJet in the event of an alarm. For example, in the event of an alarm a connection can be automatically set up to a predetermined IP address (VideoJet receiver or PC with receiver software). Alternatively alarm statuses can also be documented by e-mail. A receiver who does not have a video reception device can thus also be informed. In this case, an e-mail with an attached JPEG image is sent to a predetermined e-mail address. Connect on alarm: Select On to automatically set up a connection to a predetermined IP address. Otherwise select Off. Live video receiver IP address: Enter here the IP address to be notified in the event of an alarm. Remote password: If applicable, enter the password to get access to a transmitter unit. Live video auto-connect: Select On if at each restart, e.g. after a connection breakdown or network failure, an active connection is to be automatically set up to the IP address defined above. Otherwise select Off. Send alarm e-mail: Select On to send an alarm e-mail in the event of an alarm. Alarm e-mail address: Enter the e-mail address for the alarm e-mails. 47
Configuration with web browser Relays settings You can configure the switching behaviour of the relay outputs. You can assign the relays the function of an NC contact (closed at zero current) or an NO contact (open at zero current). Furthermore you can specify for each output whether the output reaction is to be bistable or monostable. In bistable mode, the triggered status of the relay is maintained. In monostable mode, you can set the time after which the relay is to return to its non-activated state. You can select various events for the output which automatically activate the output. It is thus possible, for example, to switch on a floodlight when a motion alarm is triggered and to switch off the floodlight again at the end of the alarm. Relay action Idle state: Select Open if the relay is to function as an NO contact or Closed if the relay is to function as an NC contact. Operating mode: Select an operating mode for the relay. 48
Configuration with web browser If a floodlight activated by an alarm is to remain switched on at the end of the alarm, select Bistable. If a siren triggered by an alarm is to sound for a period of 10 seconds, select Monostable 10s. Relay follows: If necessary, select a particular event which is to trigger the relay. The following events are possible as triggers: Motion alarm: Triggering by motion alarm Input pin: Triggering by external alarm sensor Video loss: Triggering by video signal alarm Connection: Triggering at each connection set-up Remote input pin: Triggering by switching contact of the remote station None: No relay triggering by events Relay name: Assign a relay name to each relay output here. Relay Operation Trigger relay: Use the button Relay to switch the relay by hand (e.g. for test purposes or to actuate a door opener). 49

Subnet mask: Enter the corresponding subnet mask here if the device is to communicate via a subnet. Gateway IP address: Enter the corresponding IP address here if the device is to independently set up a connection from the local network. Otherwise the field can be left blank (0.0.0.0). 52
Configuration with web browser Mail server IP address: Enter the corresponding IP address here if the device is to use the e-mail function. Outgoing e-mails are transmitted via the entered address to the mail server. Otherwise the field can be left blank (0.0.0.0). Mail reply IP address: Enter an e-mail address here if the device is to use the e-mail function. The input informs the receiver of an e-mail about the sender. Otherwise the field can be left blank (0.0.0.0). Multilink Multicast In addition to the 1:1 connection between one transmitter and one receiver (unicast), the offers the possibility of receiving the signals from a transmitter with several receivers simultaneously. This is performed either by duplicating the data stream in the transmitter and subsequent distribution to several receivers (multi-unicast) or by distributing a single data stream in the network proper to several receivers of a defined group (multicast). Note A precondition for multicast mode is a multicast-compatible network using the UDP protocol and the IGMP protocol. Other group management protocols are not supported. The TCP protocol does not support multicast connections. Enable multilink H.323: In multilink mode, the data stream is duplicated in the VideoJet 400 or in the network (group IP). The data are encoded according to the H.323 standard and are thus compatible with other applications (e.g. MS NetMeeting). Benefits of the H.323 coding are a higher data rate with a lower bandwidth in the network and a faster and more stable communication thanks to the robust data protocol. The supports multilink mode with a maximum of 5 simultaneously connected receivers, whereby an audio voice link is only possible to the first receiver (the first connection set up). 53
Configuration with web browser The transparent data link is maintained by the first device as for the audio link, although the data connection is automatically torn down after 15 seconds inactivity and another device can exchange transparent data with the receiver. For the multilink mode, the network does not have to be suitable for multicast operation, as the is also multi-unicast compatible. The duplication of the data in the device requires a high computing power and could under certain circumstances lead to a deterioration in the image quality. In this case, you should reduce the data rate of the transmitter slightly. With the setting Multilink On and Multicast group IP address = 0.0.0.0, the device operates in multi-unicast mode (copying the data streams in the device). With the setting Multilink On and a valid Multicast group IP address, the device operates in multicast mode (duplication of the data streams in the network). Enable multicast streaming: During multicast streaming, the sends a permanent data stream to the specified group IP address. No specific receiver is defined. Each receiver is thus able to receive the data. The transmission rate is determined purely by the transmitter and has to be set there. For this, a valid multicast group IP address must be set. Multicast group IP address: A precondition for the multicast mode in a multicast-compatible network is the establishment of a special IP address (class D address). The network must support the establishment of a group IP address and the Internet Group Management Protocol (IGMP). The address range is from 224.0.1.0 to 238.255.255.255. Multicast video port: The video port does not have to be configured manually and is shown here only for information for special applications. Multicast audio port: The audio port does not have to be configured manually and is shown here only for information for special applications. 54
