Our own Apollo System

Apollo system

Our Apollo system has multiple headsets in conjunction with a compact interface system housed within a case/backpack, creating a simple drop down or mobile intercom system supporting multiple wireless headsets in full duplex communications. It has the ability to add in a hand portable or transportable radio set and the system allows each operative to hear any radio calls being made, and any one of the party can reply to the call. If any user moves outside of range, a tone will be heard and once the user comes within range again, the system will automatically reconnect. Apollo contains a universal charging system using vehicle supplies to power and charge it. Mains chargers are also supplied, and the intercom interface system comes witha  Lithium Li-ion battery back with over 20 hours use. The headsets all contain Li-ion batteries for over 24 hours use, and just a 3 hour recharge., more than adequate for most uses.

COFDOM VSTx TRANSMITTER AND SRx RECEIVER 

 

The VSTx Ultra compact SD COFDM Transmitter

is an ultra small, low power, SD, COFDM , video/audio/data transmitter with standard selectable modulation bandwidths of 6, 7 and 8 MHz. It features superb H.264 SD encoding and operates in the standard 2k DVB-T COFDM mode.  The first model has standard connectors and can easily be used by agents in the field for body worn video wires and other applications, the second features a small flex ribbon interface cable that is ideal for integration with cameras in small hidden locations.   

 

The VSTx transmitter can be operated in 1.25 MHz or 2.5 MHz narrow bandwidth COFDM modes. This mode uses the RF spectrum more efficiently, permitting more transmitters to be used simultaneously, or permitting their useful range to be extended. Narrow bandwidth also delivers extended usable range with no additional power output required. This  saves battery power and extends runtimes.  

 

 The SRx HD/SD Dual Input diversity COFDM Receiver is a ruggedized dual diversity COFDM receiver offering exceptional RF performance combined with high ease of operation. It features superb H.264. SD and HD decoding and these features are combined in a durable weather resistant package. The SRx features AES decryption capabilities, making it ideal for public security monitoring, covert surveillance, and other secure transmission applications. It supports a broad array of video output signals, including HD, ASI, HD-SDI, and SD-SDE. The unit also has a composite video output, which is dwon converted to SD when receiving HD signals. 

 

In addition, the SRx also features an Ethernet port for streaming video over a LAN to remote software or hardware decoders. This allows many remote viewers to monitor the same video increasing situational awareness.  It uses standardized cables and requires no special adapters.
