System Description
The SDR900H is a professional-quality wireless transmission system designed for
sending digital signals, simplex (one-way), for example, pan/tilt/zoom camera control.
The system employs 900MHz frequency-hopping spread-spectrum technology. The
system will operate interference-free with Trango Falcon or Eagle series wireless video
transmission systems to form a complete wireless solution for PTZ and video
transmission.
Note: The SDR900H is a data transmission system, and is not limited
to PTZ applications.
Installation
Make sure that you have tested your serial data devises, such as PTZ controller and
receiver/driver/dome, using a direct connection (with wires) before attempting to
establish the wireless link. Also, it is recommended that the wireless link be “bench
tested” at short range before deployment.
To obtain the best performance, and transmission distance, the following rules of thumb
should be followed:
1) Mount the transceiver antennas above human and mechanical traffic, the higher
the better. A ten-foot steel mast on top of a building is typical. Make sure that the
mast is well grounded with a wire of 8 AWG or greater.
2) Keep the transmission path as open as possible. Objects such as walls and
metallic objects near the transmission path may reduce the transmission distance.
3) Do not add additional lengths of cable to connect the transceiver to the antenna, as
significant losses in signal and reduced transmission range will occur.
4) Keep the data link (shielded twisted-pair) cables as short as possible to prevent
distortion of the data and possible interference from video running on coaxial
cable nearby.
The SDR900H radios come pre-mounted in a NEMA 4X aluminum enclosure. This
permits the unit to be mounted outdoors.
Important!
The SDR900H enclosures are designed to be mounted on a steel pole with a
maximum diameter of 2 3/8”. The pole must be securely mounted into the ground, or to
a structure to prevent movement of the antenna and camera in windy conditions. This
pole also acts as an earth ground and
must be grounded
, or you will need to run an
external ground wire from the radio to ground.
