Nowadays, people always carry their phones with them. Having intelligence on a particular person's phone equates to managing info on a person. The Piranha system enables an organization to gather phone identity (IMSI, IMEI or MSISDN), while delivering advance tools to utilize the gathered information and to manipulate the phones. Using advanced technology, the Piranha operates in 2G, 3G and 4G (LTE) networks in one hardware, covering all common existing standards. Piranha brings the capability of collecting and storing the gathered info into a dedicated database, which then allows the system to manage a list of targets and alert upon detection of pre-defined suspected mobile phones. Piranha also delivers the first stage of smart situation management and intelligence investigation or tracing. Piranha can be integrated to other system and sensors for producing maximal value of data provided by the Piranha system. For example: surveillance cameras, face recognition, biometric systems, scanners, LPR (license plate recognition) system, border checkpoints and any other system.
