Comstrac - Surveillance, Jamming and Monitoring Systems

Comstrac is a leading supplier of surveillance, monitoring, homeland security and personal protection products. Comstrac are also the exclusive global distributor of Alpha 6 molecular detection systems. A main global provider of both passive and hybrid active GSM/CDMA and TDMA off-air intercept systems, ComsTrac is able to provide comprehensive surveillance and security services, with product ranges covering cellular and broadband jammers, audio and video transmitters.

GSM AND CELLULAR MONITORING SYSTEMS

The GSM intercept system is intended for passive or semi-active monitoring of GSM900 and DCS-1800, and 1900 MHz standard communication systems.

High-dynamical range receivers and special methods of signal procession enable high-quality reception, computation of session key (Kc), speech intelligibility, and the possibility to control the reverse channel at distance from the subscriber.

All forms of encryption including A5/1 can be intercepted, providing speech and SMS intercept of all targeted handsets within the operational area.

IMSI grabbing and locating options are also available where handset information is only required for capture without voice and text messaging. Other forms of intercept including Thuraya and Iridium are also available.

JAMMING SYSTEMS

RF and wide-band jamming systems are designed for paralysing and immobilising links between mobile cellular telephones and the local cellular cells. All devices within the protected area of the activated jammer will not be able to receive or transmit calls. Devices outside the protected area will not be affected.

ULTRA BROADBAND BOMB JAMMERS

Comstrac also offer a range of wltra-broadband bomb jammers that cover 20-3,000Mhz and 20-6,000Mhz using the very latest digital amplifier technology, programmable communication windows and very rapid sweep technology.

The high-power RF jammers are designed for jamming 20MHz to 3,000MHz frequencies. This jammer covers all general communication frequency bands for example walky-talky, cellular (AMPS, GSM, HighGSM, CDMA/TDMA, NEXTEL, PCS, DCS, UMTS), satellite (Thuraya, Iridium), WLAN, GPS and Wi-Fi. Bands and spots can be turned on and off according to threat information and other needs.

A range of cellular jammers for use in all areas of operation with varying ranges are available.

ALPHA 6 EXPLOSIVE AND CONTRABAND DETECTION SYSTEM

The Alpha 6 explosive and contraband detection system is an early warning indicator and direction finder for explosive and contraband detection. Alpha 6 can direct the user to explosives or contraband from up to 300m away.

Using unique molecular attraction technology, the Alpha 6 system is in active operation for both EOD/IEOD and narcotic discovery in five continents with more than 100 countries and more than 300 different departments including Presidential/Prime Minister VIP protection teams in more than 10 countries employing it.

MTRDK - RAPID DEPLOYMENT VIP PROTECTION KIT

The MTRDK has been designed to provide rapidly deployable CCTV and intrusion detection for all types of mobile operations. The MTDRK is a modular system that can be configured according to customer demands and situations.

The standard model includes:

• Fully programmable, portable, ruggedised monitoring case
• Four audio/video receivers
• Four wireless day/night camera units
• Four wireless PIR detector units

The MTDRK can also be configured with a wide range of cameras, encryption modules and sensors.

MTX SILVER REMOTE AUDIO VISUAL TRANSMITTER

The MTX Silver is a video transmitter using Frequency Modulation (FM) for both audio and video. It allows transmission via radio of images and sound from a video camera at distances up to 4km.

The transmitter can be discreetly worn on the body or used in a motor vehicle. With the remote control commander, the transmitter can be left asleep whilst no action is taking place and can be remotely switched on from a range of up to 300m.
