Introduction
The NTCS provides a simple, rugged outdoor deployable method for close observation.
It integrates a DTC NETNode IP mesh radio, a high definition PTZ camera and GPS positioning into a
single IP67 sealed unit.
NETNode IP radios can be combined in a fluid self-forming, self-healing mesh containing up to
sixteen radios.
The NETNode radios within the mesh exchange data on a single frequency, simplifying frequency
management.
The entire mesh occupies just 2.5MHz of bandwidth, 3.0, 3.5, 5.0, 6.0 and 8.0MHz bandwidths are
also selectable. The NETNode radios employ the unique DTC COFDM modulation scheme and
therefore offer excellent RF penetration and performance in the presence of multipath.
The integrated EV7520 HD Sony block camera offers a 30x optical zoom with and a 63.7° wide
angle of view. It supports video resolutions up to 1080p output, along with exceptional low light
sensitivity.
The camera’s video is encoded into an IP stream via an integrated encoder, configuration including
video encoding parameters is supported via a web page interface.
The pan and tilt drive trains are actuated by gearless stepper motors, reducing the operational
noise to a minimum. Pan and tilt speeds are zoom factor corrected, giving fine control over the
entire range of the lens.
It has absolute position feedback and therefore has the ability to self correct its actual position if
external forces act upon it.
Optional on-board recording to SD card is supported, whilst GPS positioning is available via an
optional add on module.
