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, with their excellent range and ability to operate in high multi-path and non-line-of-sight (NLOS) environments. 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, security officials have found newfound simplicity in the setup and operation of IP video surveillance equipment. Wherever you have an internet connection, you can collect or view video in real time.
But 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.
Silvus' StreamCaster™ radios provide law enforcement with the performance of COFDM and the ease and flexibility of IP. Silvus’ revolutionary Mobile Networked MIMO (MN-MIMO) technology utilizes a powerful combination of Coded Orthogonal Frequency Division Multiplexing (COFDM) modulation and Multiple Input Multiple Output (MIMO) antenna techniques to enable unprecedented throughput, range, spectral efficiency, mobility, and robustness.
Unlike WiFi-based technologies, Silvus’ 100% proprietary solution provides robust, bi-directional or mesh communications in a variety of environments from dense urban to sprawling rural plains. The radios combine to form a single frequency network, operating in your choice of licensed and unlicensed bands from 400MHz to 6GHz. And with AES128/256 encryption and IP67 construction, the Silvus radio provides unmatched mission reliability.
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. Silvus ensures your entire team is on the same page when moments count.
