KAPIRIS II and III detectors are specially designed for outdoor perimeter detection. Based on the association of two technologies, these products can be used to secure areas in which it is difficult to install infrared barriers (hilly terrain, wiring constraints, etc.). The reliability of the product is guaranteed by the passive infrared sensor and the high-frequency sensor with Dopler effect, which create a real curtain. With a maximum range of 50 m, the KAPIRIS product line is perfectly suited to complex sites, and with its technology there are no dead zones at the edge of the sensor. The sensors can also be associated with some video systems to carry out an effective alarm verification and, thus, reinforce the security level. Two products make up the range of dual-technology detectors: “KAPIRIS II: contact outputs only, can be deployed without software or setting device. “KAPIRIS III: compatible with the MAXIBUS 3000 Hub, configurable via an integrated web server, complementary to the installation of MAXIRIS 3000 3100 barriers.
