Product Descriptions
Model VT900-3A from Applied Wireless, Inc. is a high quality transmitter
designed to broadcast standard NTSC or PAL composite video signals to
the Applied Wireless model VR900-3 receiver. The VT900-3 conforms to
FCC Part 15 requirements for unlicensed use, and will transmit over
distances up to 750 feet.* The range may be increased substantially
through the use of a directional antenna (such as a flat panel or Yagi) at
the receiver.
* Unobstructed, straight line-of-sight range, when used with the standard antennas
included with the transmitter and receiver.
The VT900-3 transmitter and the VR900-3 receiver provide three user-
selectable channels of operation within the 902 – 928 MHz band to enable
simultaneous operation of up to two transmitters in a common area.
Excellent frequency stability is assured through the use of crystal
references. The products incorporate precise FM modulation and
sophisticated filters to provide stable, interference-free high quality color
or B/W video plus audio reception.
The transmitter and receiver are housed in small yet rugged aluminum
extrusion enclosures. AC power converters (12VDC) are supplied, along
with RCA phono-type video and audio cables.
The VT900-3 transmitter and the VR900-3 receiver are well-suited for
many diverse applications, including distribution of video content
throughout a building, commercial and industrial surveillance, monitoring,
security, access control, etc.
Installation Instructions
Before Beginning the Installation
Plan your installation carefully. The physical location and orientation of
the transmitter itself (and its antenna) relative to the receiver antenna will
have a significant influence on reception quality at the receiver,
particularly at longest ranges. For best results,
the transmitter and its
standard antenna, as well as the receiver antenna, should be
positioned vertically (pointing either up or down).
If necessary, use
double-sided foam tape or hook & loop fasteners (not supplied) to secure
the transmitter to a vertical surface. Also, keep in mind that the RF signal
from the transmitter will travel through most non-metallic building
materials (wood, stucco, brick, etc.), however
maximum stated reception
range is based on unobstructed line of sight conditions.
