Security sensors and detectors

Sensors extend the protection of homes, offices, warehouses and business premises with early detection of movement, door opening, vibration, smoke, carbon monoxide or water leaks. The range includes standalone detectors with an audible alarm, Wi-Fi models for the Tuya Smart app and wired or 433MHz wireless sensors for compatible PNI SafeHouse control panels. When choosing a device, check the detection type, power supply, communication protocol, compatibility with the panel or app, alarm volume, range and installation environment. Wi-Fi devices generally require a 2.4GHz network. Position a PIR sensor at the recommended height and field of view away from heat sources; install smoke, CO and flood detectors exactly as specified by the manufacturer. Use the test function regularly, check batteries and observe the stated sensor service life. Smart notifications supplement local warning signals and do not replace mandatory fire or security systems.
