CCTV (closed circuit television) is a television system in which signals are not publicly distributed but are monitored, mainly for surveillance and security purposes. The CCTV system has a very important role in systems security cameras (CCTV system, access control system, burglar alarm, PA system) nowadays.
It’s been almost 70 years since the first commercial closed-circuit television system became available in 1949, since the CCTV system continues to develop in technology and functions to ensure that our daily life is safer and more comfortable.
CCTV camera system products can do?
Five functions are summarized as follows;
1) watching is available means to see how our eyes, but this type of eyes is a camera that can monitor 24 hours a day and night without stopping for us, whatever the dark night or the adverse climate;
2)Listening is available means like our ears, because we can put the device with the phonetic function;
3)Speaking is available. Some cameras with a microphone and speaker that allow a supervisor and customers to talk to people with a range of speakers associated with the cameras. This incredible function that old generation cameras are not available becomes reality;
4) keep records for us, that is the basic functions in the security system of CCTV cameras, which will be used in forensic analysis and analysis by customers or police officers in the event that probably some days;
5)Alert function – perfect combination of the burglar home alarm system and CCTV system.
When someone enters the work area of the camera, the information detection and PIR detection devices will capture the information and send the message and video to the customer’s smartphone. Probably someone is going to do something wrong, you have two choices to stop it. Both are available. On the one hand you can inform the policemen or your workers to stop it, on the other you can use your mobile to send warnings to the bad guys “get out! The policeman is coming. Because this camera with the microphone so you can talk to the camera from your mobile phone at home or any place with the network.
The siren will sound and the white lights will open that will send the message to the kids: stop, you’re under the monitor, keep in mind your behaviors!
CCTC system applications for a crime prevention system
A 2009 systematic by researchers from the Northeast University and the University of Cambridge used meta-analytical techniques to group the CCTV media in different studies. The results indicated it:
1. Cause a significant reduction in crime by an average of 16%.
2.The greatest effects of CCTV cameras have been found in the parking lot, where the cameras are reduced on average by 51%.
3.CCTV regimes in other public contexts have had small and not statistically significant effects on the reduction of crime by 7% in cities and urban centers and a 23% reduction in public transport facilities.
4. When ordered by country, the CCTV system in the UK accounted for most of the decrease; the decline in other areas was insignificant.
A truth should be mentioned that criminals are usually not the first time they commit illegal acts before being arrested by the police, almost several times before. So why always like this? The criminal psychologist said, they are always thinking, I’ll be fine, no one is watching me, checking me, no proof, that mentality let them commit crime again and again deeply. We should do something to close this fluke mind in order to decline the crime trends. More obviously, CCTV systems are the best choices for us.
Two reasons why the CCTV system is effective in preventing property and violent crimes
One reason:decrease the trend rate before the crime. As we mention above CCTV cameras with monitoring, listening, speaking, recording and alerting functions, so smart and tireless work for us. People will abandon their illegal actions when they realize they are under the monitoring area. An interesting story of my friend who lost his bicycles three times in two months because his bicycles were stolen by thieves. I suggested he install some cameras in his backyard and he did, since then his bikes have never lost again.
Reason two: The CCTV system can provide clues and evidence for the victims and the police, which will allow criminals to escape and accept legal sanctions. This is also the reason for import that will discourage someone from committing a crime.
Monitor employees, standardize employee behavior and improve productivity
Organizations use CCTV to monitor workers’ actions. Each action is recorded as a block of information with subtitles explaining the operation performed. This helps keep track of workers’ actions, especially when they are making critical financial transactions, such as correcting or canceling a sale, withdrawing money or changing personal information. Actions that an employer may wish to monitor could include:
- Scanning of goods, selection of goods, introduction of prices and quantities;
- Input and output of the operators in the system when entering passwords;
- Elimination of operations and modification of existing documents;
- Implementation of certain operations, such as financial statements or cash transactions;
- Moving goods, scrapping and counting of revaluations;
- Control of fast food in the kitchen;
- Change of settings, reports and other official functions.
- Probably lazy employees or some managers are working not following the company rules.
CCTV cameras will bring all the factual information to the customers for control so that things like company, factory, supermarket, farm, minerals, home, etc. can be well organized, the cameras never tell lies to their master, but people somehow!
Industrial monitoring
Industrial processes that take place in conditions dangerous to humans are now often controlled by closed-circuit television cameras. These are mainly processes in the chemical industry, mining engineering in reactors or structures, etc. Industry-specific, waterproof, explosion-proof camera will be used in these areas to satisfy a harsh environment that humans cannot.
Traffic monitoring
Many cities and motorway networks have traffic monitoring systems, using closed-circuit television to detect congestion and report incidents. However, many of these cameras are owned by private companies and transmit data to drivers’ GPS systems.
The CCTV system plays an important role in our daily life, not only in home and public security system, but also to improve productivity for our business, while it is still little used in the USA market. Probably the people there limited in the knowledge of the importance of the CCTV system, so popular propaganda and professional driving technology in practice is necessities.
