Mesh could also be used to quickly deploy a multiple node surveillance system around an
area of interest. The NETNode units could be used to contribute Video or IP data such as
stills photography or sensor data.
The NETNode can accept video from a standard composite (PAL/NTSC) camera or an IP
camera can be connected through the MESH Network. To connect a standard composite
video signal into a MESH NETNode the NETNode-AVI-UP option must be fitted into the
NETNode.
The MESH is able to support 3 or 4 full quality video links through the one frequency – if 3
nodes were to contribute video simultaneously then the bit-rate for each link would have to
be adjusted to roughly 700kbps per video service. Full frame rate video can be supported at
700kbps but at reduced resolution – typically ½ resolution or SIF resolution would be
selected. Higher resolutions could also be supported – even up to full resolution but typically
not at full frame rate.
A 4 or 5 Node Mesh network (when configured to operate in 3.5MHz bandwidth mode) can
have up to 3Mbps of data capacity available for transmission of information between the
Nodes IF every Node can see every other Node and the link quality between all the nodes is
good. Note that if information needs to be transmitted through a chain of Nodes or if the link
quality is not good then the useful information rate available in the Mesh reduces.
NOTE: Some Phase 2 Mesh Nodes (4.4 to 5GHz) units and post Sep 2010 delivery (2.17 to
2.50GHz) Mesh NETNodes can support a 5MHz bandwidth that allows up to 5.5Mbps of
useable data in the Mesh Network. To discover if your unit supports 5MHz bandwidth you
can look at the Board Type in the Information Pane of the web browser interface. See
Section 4.12 Information Tab for details on how to discover the Board Type.
