2. SITE PLANNING
2.1. REQUIRED INFRASTRUCTURE
The Sensor requires wired network connectivity in the form of ethernet, preferably 1G-Base-T, but also
100MBase-T, and a routable path for it to reach public IPv4 address space. It can be powered by Power-Over-
Ethernet (PoE) that is compliant to at least the 802.3at specification. Optionally, it can be powered from a DC
power supply that provides 44VDC to 56VDC and a minimum of 26W of power.
2.2. LOCATION
Since the Sensor is a radio receiver the best locations place as little obstruction between the areas to be
protected and the Sensor so that signals arrive by a direct path and as strong as possible to maximize range.
Of greatest concerns are metal and other conductive materials which actively shield signals from reaching the
Sensor. Air handling duct work, glass tinted with a metallic coating, re-enforcing steel in concrete, and large
metal office furniture (such as filing systems) are all common examples of surfaces that will actively prevent
signals from passing through and possibly reflect them in different directions.
Of lesser but still significant concern are non-conductive dense materials such as concrete, stone, masonry or
earth that will strongly attenuate radio signals that pass through them.
The Sensor is constructed from special materials that convey fire resistance without impeding RF signals such
that the Sensor can be located in air handling spaces (or plenums) which are governed by special fire and
building codes. These commonly occur above suspended false ceilings or below raised floors in buildings.
The Sensor whilst durable is not constructed for use in a wet, humid or outdoor environment, and care should
be taken when siting it that it is not subject directly or indirectly to water condensation. It should not be sited
in a health care facility where it will be subject to regular wet cleaning procedures as part of a disinfection and
sterilization program.
The Sensor is not designed to operate in hazardous locations where specific fire or explosion hazards may exist
due to flammable gases, vapors, dusts, fibers etc.
