Tamper Proof Container Systems. TPCS UK Ltd has patented technology to detect any and all attempts at intrusion into any confined space, at a resolution of 6mm. The maritime container product has been launched and has been independently tested at the UK's Loss Prevention Certification Board (LPCB). The secure container incorporates GPRS and/or Iridium satellite communications, to enable low latency communication of the alarm event. TPCS can therefore, instantly detect attempts at intrusion, communicate the alarm event in real time and provide back office support, to ensure that the alarm message is efficiently disseminated.
