Check to be sure that the following components and parts are contained in the package:  
Power conversion cable ...................................................................................................... 1  
Network Video Receiver Instruction Manual ........................................................................ 1  
3. GENERAL DESCRIPTION  
TOA's N-VR2010 Network Video Receiver can convert images transmitted by the digital signals on a LAN  
from a Network Camera or Network Video Transmitter into an analog composite signal and output it. MPEG-4  
allows smooth moving images to be monitored.  
The N-VR2010 can transmit bi-directional sub-band ADPCM or PCM quality voice. Its power supply features  
PoE compatibility in addition to 24V AC or 24V DC operation, permitting simplified wiring work and cable  
savings during construction by supplying power via the network.  
The N-VR2010 has a 12V DC power output which supplies power to the equipment such as remote  
controllers.  
Since the N-VR2010 is equipped with RS-232C and RS-485 connectors, it can remotely operate a Digital  
Video Recorder and Combination Dome Cameras connected to the Network Video Transmitter when used in  
combination with a Remote Controller.  
4. FEATURES  
• After receiving streamed MPEG-4 data, the Network Video Receiver decompresses and converts it into an  
analog signal, and then transmits the analog video signal.  
• The Receiver is equipped with audio input and output (line/microphone input and line output) that enable  
two-way signal transmission.  
• External connected equipment, such as the Digital Video Recorder, Multi-Switcher, and Combination Dome  
Camera can be controlled via the RS-232C/RS-485 interfaces.  
• A built-in web server can be accessed using a web browser.  
• The Receiver can function as a monitor system if the supplied software decoder is also used.  
• Since the hub is compatible with PoE Standards, power can be supplied to the Network Video Receiver  
using a single network cable. This eliminates the necessity for preparing a separate power supply in each  
camera installation location, and greatly improves installation freedom. PoE (Power over Ethernet) (This  
complies with the IEEE802.3af standard and allows simultaneous transmission of both normal data and DC  
power using a 10BASE-T or 100BASE-TX network.)

5. HANDLING PRECAUTIONS  
• Do not give the Receiver a great shock or vibration, as this will damage the Receiver.  
• It is recommended that the Receiver be always used in locations where the ambient temperature ranges  
from -0°C to +50°C and humidity levels of less than 90% to ensure that no condensation is formed.  
• To clean, wipe with a dry soft cloth. Never use benzene, thinner or chemically processed towel as the  
Receiver's plastic or other parts may be deformed or discolored.  
• Installing the camera cables and monitor cables in close proximity to fluorescent lamps or other electrical  
appliances can downgrade the picture quality. In such cases, change the wiring.  
• If there is a strong electric or magnetic field near the Receiver, such as television transmission antennas,  
motors or transformers, this may distort or roll the monitor picture. In such cases, run the entire wiring route  
through metal conduit tubing.  
• Shielded (STP) network cables must be used with this unit to ensure compliance with EMC standards.  
• Secure sufficient space for cable installation.  
• Install the Receiver in well-ventilated locations.  
• Use appropriate cables to prevent electrical failures.  
• Install cables so as to prevent their damage and provide ample cable slack if they need to be stretched taut.  
• The IP address, subnet mask and gateway IP address must be set.  
• When a connection is established between the Transmitter and multiple Receivers, if the data rate requested  
by each Receiver differs, the transmission will be limited to the minimum set data rate.  
• Personal computers running Microsoft Windows XP are required when setting the Network Video Receiver.  
• TOA's software decoder does not support Macintosh or Unix operating systems.
