Line of sight vs. indirect signal paths
Unblocked signal paths
Avoiding closed metal boxes
Noise in the environment
If mounting the sensor directly on metal can not be avoided, beware of reduced range. E.g. for detecting the opening
and closing of a metal door, the Cloud Connector might need to be placed closer to this sensor than sensors placed on
other materials.
The more complex the geometry of the installation site, the more di$cult it is to predict the signal paths. In some cases
such as concrete shafts, the signal may bounce its way along the channel.
It is always better for the sensor to have as little obstruction between it and the Cloud Connector as possible. In
environments where people and trolleys/crates etc. move around, signal strength may vary signi#cantly depending on
the time of day and activity. Placing Cloud Connectors high in the environment reduces many of these e!ects.
Metal re"ects radio signals. A completely closed metal box will drastically reduce range. Placing sensors in rooms with
the metal "oor, walls and ceilings will need a Cloud Connector inside the room, and in many cases will require the
Cloud Connector to be connected through Ethernet.
Closed fridges and freezers generally have non-metallic openings, such as "exible material around doors and hinges.
The signal can thus escape the metal case, but not without loss.
The Cloud Connector should not be placed in a metal cabinet, such as a power installation cabinet.
