In the field of perimeter security and protection, we deepen the transformation and application of military（去掉military） special sensor networks. Relying on our developed composite sensors and self-organizing network communication systems, SCIFINE provides IoT system solutions for unattended perimeter security warning and monitoring, which can construct a non-contact, digital and networked all-weather unattended alert system. We also provide IoT system solutions to establish fixed perimeter security systems, mobile perimeter security systems and hybrid perimeter security systems to obtain full-dimensional dynamic on-site information in real time, ensuring accurate and reliable information for headquarters and front-line public security officers.
