Introduction
The TMC 3 provides a simple, rugged outdoor deployable method for close observation.
It integrates the Silvus StreamCaster 4200 MIMO Mesh radio, a high definition PTZ camera and GPS
positioning into a single IP67 sealed unit.
The StreamCaster 4200 from Silvus Technologies offers outstanding RF performance in both of the
supported S and C bands. It has excellent range and data bandwidth, with optimum size, weight
and power consumption characteristics.
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, this produces
simultaneous H.264 and MJPEG encoded streams. Configuration of the encoder including video
encoding, trigger settings and network 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. It also offers eight user preset settings that can be saved allowing PTZ
framing and camera racking profiles to be easily recalled.
Two removable antennas connect via TNC connectors, this allows the TMC 3 to be mounted in the
orientation chosen by the user.
The TMC 3 also features a GPS module that provides positioning information which is made
available through the Mesh radio network link.
