4 Installation Installing the unit With its ultra-compact dimensions, the 7700 Series unit is particularly well suited for installation in cabinets. Warning! The unit is intended for use indoors or in a protective enclosure. Select a suitable location for installation where the equipment is not subject to extreme temperatures or humidity. The ambient temperature must lie between 0 and +50 °C. The relative humidity should not exceed 80%. The unit generates heat during operation.
Network You can connect the 7700 Series unit directly to a 10/100 Base-T network or via a hub. Use a standard UTP Category 5 cable with RJ45 connectors. – Connect the unit to the network using the Ethernet jack. Alarm inputs The 7700 Series unit has two alarm inputs on the orange terminal block. The alarm inputs are used to transfer signals from external alarm devices, such as door contacts or sensors.
Warning! Do not connect the 7700 Series unit to a power source until all the other connections have been made. Once the video server is connected to a power source, its status LED light will flash red for a few seconds. The unit is ready for operation as soon as the light turns steady yellow. If the network connection is in order, the yellow "network connection" LED will also light up. The flashing orange "data transmission" LED indicates data traffic on the network.
– Start up a terminal program such as HyperTerminal. – Enter the user name service. The main menu will be displayed. – Enter I to open the IP menu. – Enter i. The current IP address will be displayed, and you will be requested to enter a new IP address. – Enter the desired IP address and press Enter. The new IP address will be displayed and becomes effective following a restart. Additional parameters Using the terminal program, you can check other basic parameters and modify them where necessary.
Configuration using a Web Browser 5 Establishing the connection The integrated HTTP server allows the unit to be configured over a local area network using a Web browser. This option offers considerably more possibilities and is more convenient than configuration using terminal software. It also allows live video images to be displayed. Note Before the computer can decode live video images, the appropriate, special ActiveX Controls must be installed.
If the unit is a transmitter, the home page will be the Video Viewer (which shows the live video image, if a camera is connected to the encoder). The Connection page will be displayed as the home page for a receiver. It shows a snapshot from the video source for the transmitter currently connected, and the unit searches the network automatically for available transmitters. Note If a connection cannot be established, the unit selected may already be communicating with another remote station.
– Enter the user name and password in the appropriate fields. – Click OK. If the password is correct, the 7700 Series unit home page will open. Choosing the configuration mode There are two options for configuring a 7700 Series unit or checking its current setup: • The Installation Wizard • The Configurator All settings are stored in the 7700 Series unit memory, and they are preserved even if the power is interrupted. Use of the Installation Wizard is recommended for initial setup.
General procedure The screens for the Installation Wizard will be shown in sequence, allowing you to work quickly and easily. The upper part of the window always contains information about the settings options. The current settings are shown in the lower part of the window. You can change settings by entering the desired value in a text field or choosing it from a list. The navigation buttons for the Installation Wizard are at the bottom of the window. You can switch between pages of the Wizard at any time.
The basic use of the configuration pages is described below. Separate descriptions of the individual configuration pages and customizable parameters for transmitters and receivers can be found in Kapitel 6 and Kapitel 7 of this user guide. Navigation You can switch to the Configurator from the Settings page. – Click the Configurator link. The initial page will be opened. – Click one of the links on the left of the window. Other subordinate links will be shown. – Click one of the links.
6 Configuring the Transmitter Basics Below is a detailed overview of the various 7700 Series encoder settings that can be configured with the webbased Configurator. Other configuration options are described in chapter 5 of this user guide. The configurations described in this chapter should not be performed if you will be using the 7700 Series units with Latitude NVMS, as it will override them. Use the Latitude AdminCenter instead.
Language selection Use this section to change the interface language. Date and time If a number of 7700 Series units are part of a larger system, it is important that the internal clocks of all units be synchronized. Date format: Choose the desired date format: (Europe: DD.MM.YYYY; USA: MM.DD.YYYY; Japan: YYYY/MM/DD). Unit date: Enter the date in this field. Since the system time is controlled by the internal clock, it is not necessary to enter the day of week.
Camera name The camera name simplifies identification of the remote camera location, for example in the event of an alarm call. It can be shown in the video image if this feature is enabled and configured (see page 21). Display stamping Various overlays and stamps can be added to the video to provide important supplemental information. These overlays can be enabled individually and arranged on the image in a clear manner. Camera name stamping: This field sets the position of the camera name overlay.
MPEG-4 Encoder configuration The 7700 Series transmitter has two MPEG encoders that can be configured separately. This allows for the transmission of two different video streams, which can be used for different applications (e.g. live viewing and recording). There are several pre-programmed profiles, optimized for different application scenarios, available for each MPEG encoder. Individual settings in the profiles can be changed, and modified profiles can be saved under a new name.
• low delay (2CIF) for high bandwidth connections, 704 × 288 pixel resolution • low res. (CIF) for moderate bandwidth connections, resolution 352 × 288 pixels • DSL for DSL connections with 500 kbit/s • ISDN (2B) for ISDN connections via two B channels • ISDN (1B) for ISDN connections via one B channel • MODEM for analog modem connections at 20 kBit/s • GSM for 9600 baud GSM connections Preset parameter name: Enter a name for the current profile.
Video input settings The 75 Ohm termination of the 7700 Series unit can be set here. If the video signal is to be looped through, the termination must be set off. The default setting for the video input termination is On. Video input termination: To loop the video signal through choose Off. Audio configuration In addition to video data, the unit can also transmit audio signals. The transmission of audio takes place at the same time as that of the video data and thus increases the size of the data stream.
Unified picture detection: The 7700 Series unit can trigger an alarm if the camera image shows too little contrast, possibly indicating that the lens has been sprayed with paint or covered in some way. Select On to enable this function. Motion alarm: Select On if the unit is to respond to a motion alarm. Motion detection is configured on a separate page (see page 26). Alarm input 1: Select On if the alarm is to be activated by external alarm sensor 1.
Alarm IP address: Enter the IP address of the device with which a connection is to be established in the event of an alarm. Remote password: Enter the password for the remote device (if it has one) that is to be contacted in response to an alarm. Live video auto-connect: Select On here if an active connection should be established after each reboot, for example following a connection failure or power failure.
Motion detector Select On to activate the video sensor. Select sensor field You can select the areas of the image to be monitored by the video sensor. The video frame is subdivided into 396 square cells. Each of these cells can be activated or deactivated individually. If it is necessary to exclude particular regions of the camera field of view from the monitoring process due to continuous movement (a tree moving in the wind, etc.), the relevant cells can be deactivated.
Motion tracking In some situations you may want an alarm triggered only if the movement detected is in a particular direction. In such cases, enable motion detection and select the direction of movement required to trigger an alarm. – Select On to enable the motion tracking feature of the video sensor. Tracker The Tracker field shows an arrow indicating the current motion vector in the video image. The checkboxes at the corners of the field are used to select the directions to monitor.
• Off No relay triggering by events • Connection Triggering caused bby connection establishment • Video alarm Triggering caused by loss of the video signal • Motion alarm Triggering caused by the motion alarm • Local input 1 Triggering caused by alarm input 1 • Remote input 1 Triggering caused by a relay contact at the target location (only when a connection is established) • Unified picture Triggering caused by a lack of contrast in the picture Relay name: A name can be assigned to the relay in this field.
Baud rate: Select the value for the data communication rate in Bit/s. Data bits: The number of data bits per character cannot be changed. Stop bits: Select the number of stop bits per character. Parity check: Select the type of parity check. Interface mode: Select the desired protocol for the serial interface. Half-duplex mode: Choose the setting appropriate for your application.
Gateway IP address: Enter the corresponding IP address here if the unit is to establish a connection outside the local network independently. Otherwise, this field can remain empty (0.0.0.0). Video/Audio transmission: If the device is used in front of a firewall, TCP (Port 80) should be selected as the transmission protocol. For use in a local network, choose UDP. Warning! Multicast operation is possible only with the UDP protocol. The TCP protocol does not support multicast connections.
Multicast settings In addition to a "one on one" connection (unicast) between a transmitter and a receiver, the 7700 Series unit also supports multiple connections. With multicasting, several decoders receive the video signal from an encoder at the same time. There are two methods for multiple connection: multi-unicast and multicast. In multi-unicast mode, the unit's data stream is duplicated and passed on to multiple receivers.
Multicast audio port: With MPEG-4, video and audio data is transmitted via separate ports. To transmit MPEG-4 with audio you must assign a dedicated audio port. Note Audio data is only transmitted if the corresponding function on the Audio configuration page is enabled (see page 24). Multicast packet TTL: This value determines the "life span" of multicast packets on the network. If multicast is operated via a router, the value must be greater than 1 to ensure that the packets are passed on.
Video Viewer configuration The appearance of the Video Viewer can be set up to suit your requirements. You have the option of displaying various information and operating controls in addition to the video image. Moreover, individual background graphics can be used for the main window and for the upper area of the window (banner). Note Either GIF or JPEG file formats can be used. The file paths must correspond to the access mode (local paths such as C:\Images\Logo.
Video from Encoder on live page: Select whether to use encoder 1 or 2 in the Video Viewer. Panorama (Sony camera only): Selecting this option enables the display of a panoramic image. The panoramic image is shown in the upper part of the browser window. It consists of five single images that can be updated any time (see page 48). Note The panoramic image feature is only available with Sony EVI-D100 or EVI-D30/31 cameras.
This allows a 7700 Series unit unit to be serviced and updated remotely without intervention by a technician to make on-site changes to the unit installation. The latest firmware can be obtained from DVTel Technical Support or downloaded from the Internet at our Web site www.dvtel.com. Warning! Before starting the firmware upload, make sure you have selected the correct upload file! Uploading the wrong file can result in the unit no longer being addressable, requiring it to be replaced.
