You don’t need a key to start your car or unlock the front door. A voice command, fingerprint or a scan of the retina is enough to determine whether access is allowed. Modern security technology usually works only with frequency control components and battery packs.
Intelligent equipment control now comes as standard in a variety of buildings, warehouses, and residences. Smoke detectors, surveillance cameras and automatic access control systems are being used more and more in everyday life and for private applications. It is particularly important that the devices send reliable information and are fail-safe. Jauch quartz crystals with narrow frequency tolerances and lithium ion batteries have a part in ensuring that everything is smartly and securely controlled. The IoT (Internet of Things) poses many new challenges for us.
