ECM701M Portable Faraday Cage Unit for Forensic Analysis Applications

ECM701M Portable Faraday Cage Unit for Forensic Analysis Applications

The ECM701M is a small portable unit designed to be used for the safe forensic analysis of cellular devices such as phones or tablets. The unit can operate using an internal battery for over 6 hours making it suitable for applications in the field. For longer periods an external 12VDC power source can be used.

There is a special near field antenna (NFA) in the lid to provide a localised non polarised isolation field evenly above the lid area in effect creating a virtual hemispherical Faraday Cage. This allows the analysis of both phones and tablets without the fear of remote interference over cellular networks or nearby WIFI sources. The characteristics of the NFA cause the isolation signals to reduce rapidly with distance so beyond 1metre there is no interference with adjacent devices. The characteristics of each transmitter module is programmed via a special app running on a Windows based PC.

Once the desired the parameters have been set, they are stored within each unit. The user now simply powers up the unit and all transmitters will function according to the options that have been set. The internal log monitors all changes to the configuration. The application software also contains a program which facilitates remote diagnosis of each unit via the internet which obviates the need to return the unit when software updates are required.

Operational modes and functions

The operational parameters for the unit are programmed in using the special Windows application.

The two integral countermeasure units are programmed separately via the USB sockets on the front panel.

The App has a small database of national variations so when the specific country is selected the operators and frequencies allocations are displayed. The database can be enhanced on request.
