Automated building technologies come in many innovative forms, often manufactured by leading specialists, such as Siemens. Although a good deal of these technologies are used in the field of building safety, such as fire prevention and warning products, a number of the latest ones are more focussed ensuring buildings work at their optimum level for the people inside. Some automated technological advances for buildings, for example, deal with light control matters or HVAC air conditioning. Individual room temperature sensors are now installed in a good deal of big office buildings to allow heating and cooling technologies to be automated and delivered just where they are needed, for instance. In the field of building security, automated technological advances include a range of wireless cameras, miniature lenses and PIR motion detectors. In homes, automated building technology is now commonplace just as much as it is in commercial structures. Often retro-fitted to dwellings, products such as radio controlled humidity sensors and smart metering devices are frequently installed. Along with such professionally-fitted building products, some are designed for the mass consumer market and require no special skills to install. Examples of technologies that fall into this category include domestic dimming actuator socket adapters and wireless smoke detectors.
