It is installed in a ceiling-mounted manner, requiring no calibration, and is capable of detecting fire conditions in a 360° radius. Utilizing surface-mount technology, it can resist interference from EMI and RFI. Once it \"captures\" the \"signal\" of an object burning, it will upload the signal to the cloud platform, ensuring the continuity of data transmission\n\u003cbr\u003e\u003cbr\u003e\nThe HKT SD-300 is compact in size, easy to install, aesthetically pleasing, with all antennas\nbuilt into the device, making it suitable for different types of mounting surfaces, and ideal for use in office areas, living areas, and residential areas\n\u003cbr\u003e\u003cbr\u003e\n\n\u003cbr\u003e\u003cbr\u003e\n \u003cb\u003e\u003ca href=\"https:\/\/www.scopious.co.nz\/\"
