Product Description



The world’s most powerful tactical MIMO radio.

SC4400 delivers the power of 4×4 MIMO in a ruggedized package. SC4400 is ideal for use in fixed infrastructure, vehicular, long range, and airborne applications where maximum performance is desired.


  • Up to 8 Watts of output power (up to 32W effective performance thanks to TX beamforming)
  • Rugged outdoor rated housing with optional pole mount and surface mount hardware available
  • Available in 3 form factors to suit a variety of applications:
    • Rugged with straight RF connectors (designed to be mounted horizontally)
    • Rugged with right angle RF connectors (designed to be mounted vertically)
    • Non-rugged OEM (for embedding in custom products and sub-systems


Today’s digital Coded Orthogonal Frequency Division Multiplexing (COFDM) video transmission systems have proven to be a reliable alternative to yesterday’s analog Frequency Modulation (FM) systems. However, traditional COFDM systems are designed to transmit video and audio in only one direction. Any operations requiring a return channel for PTZ camera control or intercom audio would require separate wireless links to handle the signals.

With the recent proliferation of cellular communications, WiFi and network connected cameras, teams tasked with security and safety have found simplicity in the setup and operation of IP video surveillance equipment. Wherever you have a network connection, you can collect or view video in real time.

However, COTS IP transmission solutions come with limitations. WiFi is limited in range, performs poorly outdoors, and is prone to interference. 3G and 4G modems have inadequate upload speeds, recurring monthly usage fees, and cannot be relied upon during large public gatherings such as sports events, parades, or times of crisis.

Using proprietary MN-MIMO technology, Silvus tactical mesh radios provide law enforcement with the performance of COFDM and the ease and flexibility of IP, all within a private and secure network.

When accurate snap judgments are a part of every operation, your teams must be able to share critical video and data that helps your teams operate more quickly, safely and systematically. Silvus StreamCaster radios provide the vital link between all your assets, from in-building, to command post, to mission aircraft, to HQ, and everywhere in-between.


Next-generation tactical mesh radios for operations in complex environments where communications can’t afford to fail.

  • Event security
  • Perimeter surveillance
  • Covert/concealed surveillance
  • SWAT/ quick reaction teams
  • Inter-vehicle networking
  • Air-to-ground
