Vortex Communications

Since 1987 we’ve gained a deep insight into the requirements of the Law Enforcement community and whilst many of our products may have broadcast beginnings, we develop technology specifically for this market.

 Our Red CentRECORD addition to our Red Centre Hostage Victim Negotiator Kit is a 2-channel evidential recorder controlled by a tablet or workstation running our CAPTURecord GUI & CAPTUReview software. Audio from the RemoteMix-4 is fed directly into the input of an external soundcard, the live negotiations can subsequently be recorded and monitored using the CAPTURecord GUI software. All connections and negotiations still take place from the RemoteMix-4, however, the live audio can be monitored from one of the two independent headphone outputs and our ‘Instant Replay’ functions facilitates the dynamic review of negotiation from up to 3 hours ago. Furthermore, using the outputs on the external soundcard, the live audio can be streamed using our CallMe diRECt capability which sends and receives Live two-way 15kHz encrypted audio without the need for an external hardware codec.

For the back-end we’ll also have with us our Covert Monitoring Equipment which ranges from multi-position, multi-room fixed installations to our Portable CMP Suite, known as CMP Lite, which has been specifically designed to offer the same reliability as fixed Covert Monitoring Posts but is housed in one, two or three portable enclosures. Depending on the external connectivity required, a typical system consists of a CAPTURecord-4 Evidential Recorder, CAPTUReceive PSTN & GSM Diallers for additional mobile connectivity and an Audio Codec, such as a BRIC-Link or CallMe-TR, that can receive audio from remote IP audio devices.

For the front-end our RST, which stands for Record/Stream/Track is a Multi-Streaming Vehicle Audio Codec with Tracking and Cache-&-Upload capability for when the connection is lost. In normal operation the RST streams continuous, high quality 15khz, 2-channel audio, over the public internet whilst its GPS antenna provides live tracking along with a WiFi Bluetooth antenna for local retrieval of any stored audio.  Streaming two channels of high-quality audio allows better processing that can greatly improve intelligibility and remove unwanted background sounds.
