Types of Surveillance Systems
- 1. Types of SurveillanceSystems Fortunately, surveillance can come in many forms. Know what they are, now. Security surveillance systems are designed to monitor and report on changes or notable changes within an assigned field. Security surveillance systems are commonly installed to monitor public security and health, the weather and the safety of homes or commercial buildings and complexes. Security surveillance systems utilize physical observations, data analysis, video recordings and many other monitoring tools to carry out surveillance work. Most types of security surveillance systems are employed to alert, or prevent, unwanted events from happening. Health Surveillance Systems Many levels in society are equipped with surveillance systems to monitor health and wellness. The World Health Organization (WHO), for instance, manages global health surveillance systems to focus on key diseases and vaccination data. The increase or decrease of such cases is closely monitored through surveillance systems, which collect data from various sources, including hospitals, governments and non-government organizations (NGOs). The collected data are then collated and analyzed in order to understand global disease trends and create recommendations against possible epidemics or outbreaks. In a smaller scale, health surveillance systems are utilized by schools to monitor and warn about the outbreak of childhood diseases such as chicken pox, measles or even the common cold and flu. The governments will collect the data from schools, which they’ll eventually endorse into the WHO databases.
- 2. Home Security Cameras/Security Cameras for Home Security surveillance systems are generally designed to monitor the movement of people in any given area. Home monitoring systems are set up to monitor personal property, such as residences with the use of wireless lighting and a wireless security camera, while other surveillance systems are employed to monitor a building or complex of structures. In a smaller scale, the use of CCTV or wireless camera security systems, motion sensors and alarm systems for security are very common. Far more complex measures are utilized in larger scale security surveillance, similar to that managed for national security. These systems can usually survey the Internet and telephone activity, people getting into the county, movement of suspicious individuals and collect data on suspicious activity. A larger framework of national security surveillance systems will then collect data from public places. Weather Surveillance Systems To predict and forewarn about weather disturbances, weather surveillance systems are utilized to monitor weather patterns, usually on a daily basis, just like newspapers or broadcast reports. This type of surveillance system can also identify global trends, such as the recognition of El Nino and La Nina effects or the Greenhouse effect. High-tech instruments are usually associated with weather surveillance systems, such as radars and satellites, as well as computer modeling software, to collect and key in weather data and develop forecasts of weather disturbances. Weather surveillance systems are also used to assess changes in weather patterns. Simple innovations are also
