GENERAL INFORMATION
1. GENERAL INFORMATION
1.1 Introduction
Thank you for purchasing Digimerge product. The Dialup Video Server (DVS) will enable you to monitor sensitive locations and remote areas over standard phone lines. A key feature of DVS is the ability to not only visually survey a sensitive location, but to also hear what is occurring at the scene as well as speak to anyone at the monitored location. A standalone DVS unit installed on-site with video and audio feed from up to four cameras and connected to a phone line lets you see and hear exactly what is happening and verbally interact with the individuals at the sight. No special hardware is required at the operator's PC, just a modem. Images are transmitted by the remote DVS unit will be decoded by a special client software and displayed on the screen or stored onto a hard disk for later examination. The operator, who can be located several thousand miles away, is in complete control of the DVS and any cameras attached to it. This allows for incredible expandability and flexibility of the security and surveillance network. Important features of DVS-based surveillance system include:
• DVS is low cost, maintenance-free standalone unit.
• High quality Wavelet-compressed video from 4 sources and one channel full duplex
audio can be transmitted simultaneously between DVS and supervisor’s PC through an ordinary phone line (POT line) using internal PSTN modem at a bit rate up to 56Kbps.
• Optional connection types supported: External PSTN modem, ISDN modem, cellular services (GSM, CDMA modem), dedicated line modems and direct cable connections.
• DVS unit and PC client software are specifically designed for extremely low speed connections, giving the user surveillance capability approaching real-time. Maximum achievable video update rate for one camera source with a 28.8 kbps modem connection at a resolution of 170x120 is 5 frames per second.
• Snapshots – high quality/resolution images can be captured into internal DVS memory at operator’s request, while monitoring an area with low quality/resolution but high frame rate.
• Audio user interface provides full control in audio streaming mode.
• Non-volatile internal video memory plus CompactFlash (removable) are used as video
storage.
• Callback mode: DVS unit can be instructed to call a PC back and notify you about suspicious activity in the monitored area or alarm events on sensor’s inputs, and show high quality captured snapshots sequence (user defined) on the screen which can be automatically saved as a JPG or AVI file without any user interaction.
• Motion Detection is provided with adjustable sensitivity levels and camera participation in a motion monitoring cycle for every camera.
• Password protection is available to prevent unauthorized access.
• Internal timer for pictures time stamp.

REMOTE UNIT INSTALLATION
2. REMOTE UNIT INSTALLATION
This chapter describes installation procedure of the remote video surveillance unit that is the essential part of the DVS package. The remote DVS unit is a standalone device that does not need any direct connection to a PC on remote monitoring site. The unit’s exterior is shown in Figure 1.
Figure 1 DVS unit front view
The remote unit should be placed on the site that requires monitoring, anywhere within the reach of a telephone line. It is recommended to place the DVS unit as near to the video cameras as possible to avoid image quality degradation or use of expensive high-grade video cables. Maximum video cable length is 100 meters and may vary depending on cable quality.
• First, you should check DVS unit CONFIGURATION in order to make appropriate DIP- switch SW settings on the back panel of unit (see Figure 2). All possible operation modes are tabulated:
Operation Mode
Internal modem (standard) ON OFF Section 6.1 Direct cable connection (COM-port) OFF ON Section 6.2 Custom configuration (external modem) OFF OFF Section 6.3 Auxiliary (reserved) ON ON -
• Provided that you will use device with internal modem configuration, connect the telephone line (RJ11 plug) to the Line connector on your DVS unit (see Figure 2). If the same line is also to be used for as a regular telephone line or to connect a fax machine, then use the

Phone connector on the DVS. In that case, you may need to adjust (increase) the number of rings after which the DVS will respond to an incoming call in order to avoid conflicts with normal phone and/or fax usage and the associated inconveniences. See section 5.2.1 and Figure 7 on page 23 for more information on DVS configuration options.
Note: The condition of the telephone line could be a reason for low modem connection
rate and poor image transmission performance. We recommend you to avoid connecting DVS through PBX boxes because the reduced voltage may interfere with connection reliability. We also suggest that you use a direct telephone line connection to hook up the DVS unit. Finally, since the DVS system is designed for in-door use, it should not be installed in places with high humidity or extreme temperature variation.
• Next, connect one or more video cameras to any of the 4 BNC connectors on the back panel of the DVS box. DVS is capable of camera auto-detection so you are free to use any of the unit’s video inputs in any order. You may also safely mix color and black & white cameras, as long as they all conform to the same electrical and video standard (NTSC or PAL). However, mixture not recommended because of possible video synchronization problems. Then power on the cameras.
• Finally, after all other connections are completed, connect the power supply cord (DC 12V
1.2A) to the corresponding socket on the DVS unit.
Immediately after the power is supplied to the DVS unit, the board starts the internal self-test. Test progress is always shown on the front LEDs. There are 2 LEDs: POWER (yellow) and ACTIVE (green). The LEDs will behave in the manner as described below during power up sequence:
Test (power-up) behavior of DVS unit.
1. ACTIVE (green) and POWER (yellow) turn on together, then ACTIVE (green) turns
off.
2. POWER (yellow) during the whole test will indicate test progress step by step by
turning off for a short time at the beginning of each step 13 times.
3. When the test successfully passes, POWER (yellow) remains lit and the ACTIVE
(green) starts blinking 2 times per second (status is disconnected).
4. When the DVS detects a connection, the ACTIVE (green) light will blink at double the
rate it blinks in the disconnected state. If these steps do not occur with your system, disconnect and reconnect the power and try again. The detailed layout of DVS connectors are shown in Figure 2. It is very simple and well inscribed.
