What is the tracking equipment?
Supervision is a wide term involving a wide range of devices used to observe what people do, whether apparently or hidden. Although many people consider many people to be monitoring as in the field of spies and espionage, the most common tracking device that appears today is a simple camera with a closed circuit (CCTV). These cameras are seen in banks, football stadiums, many shops or on the streets of countries such as the United Kingdom. Although this term can be used to describe any tracking device, today it is most often used to describe electronic devices, unlike analog devices such as telescope or fingerprints. For example, in the UK, there are more than four million CCTV cameras across the country. In China, surveillance cameras are used with frequency and used in conjunction with advanced software for facial recognition and monitoring systems with a specified goal eventually create a register of each citizen. In the United States is due to concernOn the protection of personal data using CCTV cameras for supervision, but many municipal governments install them under the auspices of operation and later open them to coercive bodies.
More advanced form of supervision is biometric devices. These are equipment that focuses on the specific characteristics of the person who identifies them. For example, fingerprint scanners are an example of a biometric system, as well as retina scanners. More advanced scanners can analyze a person's walking when they walk to identify them or watch their voice when they speak to identify them. Although some of these systems, such as fingerprint scanners, may be obvious, others, such as walking analyzers, can be hidden.
Air supervision is another advanced form of supervision, which has seen a huge boom in the last few years, because miniturization has become more advanced and prices have fallen. SmallAir drones are able to use lasers, infrared scanners and cameras to track subjects on Earth. For example, the MQ-9 Reaper is used by the Ministry of Internal Security in the United States and is able to identify objects slightly larger than a brick of more than 60,000 feet (18,250 m) in the air.
with the growing meaning of the Internet, data mining, snooping and analysis has become an important part of supervision. There are devices that allows you to capture data at different points on the information path. For example, small devices can be connected to a computer using a USB port that captures every keyfish and can either send them to a remote computer or save it for later search. The device can also be added to the network cable to capture packets is that they are sent and accepted, no matter how safe the network can be.
Global positioning devices are another form of supervisory equipment that sees increased use, how they shrink and smaller. GPSThe device can be covertly connected to a vehicle, package, or a person to follow them while moving. RFID brands can also be used in a similar way if they are throughout the area like a city that can follow the brand movement.
Although not always grouped with a supervisory device, many older analog technologies technically falls into this category. For example, binoculars and telescopes are low-technical form of equipment that can be used to view people from long distances and that are widely available to the general public. Tripwires, pressure plates and other mechanical devices can also be used to start quiet alarms to warn someone when the intruder entered the area.
