System Description Survey and Installation Guide The VideoWave Wireless Video Transmission is a professional system designed for sending composite NTSC or PAL video signals using 1.4 GHz wireless technology. Before carrying out installation, it is important to bench test and familiarize yourself with the equipment. This manual will help with antenna choice, transmission performance, achievable distance etc. Note: The longer the radio path the more critical details of installation become.
PAGE 3
Site Survey It is advisable to carry out a survey to establish a good radio path prior to installation. This will help with the positioning of the equipment and choice of antenna. Your distributor should be able to assist with information and may be able to provide a Survey Kit and antennas. Before commencing a survey, measure or estimate from a map, the straight-line distance between the two sites. From the tables on page 9, check which type of antenna would be needed to cover the required distance.
PAGE 4
Receiver Antenna Mounting Installation of the receiver unit is basically a repeat of the transmitter installation. The antenna selection will depend on the distance from the transmitter site and the results of the site survey. When the antenna is in position, before finally tightening the fixings and securing the cable, connect the receiver unit and connect a monitor to the receiver. Check the picture on the monitor. Again adjust the antenna position if required to obtain the best possible picture.

Wireless Telemetry Telemetry for controlling PTZ cameras etc. cannot be transmitted directly over the VideoWave but requires the addition of a Radio Modem to transmit the data. The RM96XX series of modems is designed for use in the license free bands and is approved for all European countries. The modem is compatible with most commercially available video telemetry units ( see table below). 7.

IP67 Weatherproof Enclosures Videowave Survey Kit Standard Enclosure for VideoWave Transmitter or Receiver Model VTX1394SE or VRX1394SE The enclosure is supplied with a Top antenna connector, Bulkhead Plate and internal cables. The top connector is a TNC connector suitable for direct connection of a ANT0002 or ANT2350 antenna. The bulkhead also has cable glands to seal the video and power input leads.

Technical Notes Propagation/Distance For any radio link, the distance that can be achieved between sites depends on a number of factors, the main ones being; the output power, the antenna height (above ground), the type of terrain and ‘line-of-sight’. Line-of-sight means how clear the path is between the two antennas, whether there are any obstructions and how dense these obstructions are. The major effect on distance however, is the height of the antennas above ground.

Interference Because the 1.4GHz frequency band is an unlicensed public access bands, there is no control on other users. It is therefore possible that another user could be operating on the same frequency in your area. If this is suspected, turn off the transmitter and check that the LED on the receiver is RED and does not flicker GREEN. Also check the monitor, which should be clear of any moving patterns, ghosting etc.
