Mon, 21 Jun 2010 22:35:48 +0000

Ever wondered what your employees are up to during their break times? Are they chatting and relieving stress or making out with your secretary in a dark corner? Well the only sure shot way you could find out is by installing CCTV cameras within your office promises to catch them red handed in their indulgence. CCTV cameras or closed circuit television cameras are ideal for surveillance at home or in office spaces. There are usually used in department stores to see if any customer gets an itchy palm and stuffs their pockets or clothes with goodies, hoping not to pay for them. They are also used in casinos and gambling centers to monitor each nook and cranny of the floor to identify possible fraudsters or any under the table dealings that might be going on. Military also uses CCTV cameras for various security reasons and so do home owners who install them for added security or for spying on their philandering spouses. The other places where such cameras find uses are at banks and airports where security is a major concern. CCTV cameras capture video images and transmit them over a network. Unlike broadcast television they do not air their feed public access and the feeds can be seen only on select monitors. These cameras also allow for remote monitoring apart from offering security surveillance in such environments where human intrusion might not be possible or which are hazardous to humans like nuclear facilities or highly toxic gaseous environments where such monitoring is necessary for ensuring safety. Some of these cameras come with motion sensors or night vision capabilities which let them start recording or relaying data upon receipt of a motion trigger. The night time operation or infra red operation allows them to view details even zero light environments while maintaining stealth where seeing things otherwise would be impossible. An example would be to watch animal behavior in the dark in controlled environments.*Novel Uses of CCTV cameras among the PublicMany developed countries use CCTV camera systems to monitor the public so as to decrease incidence of traffic violations or prevent crime. Traffic monitoring using such cameras for example, helps direct traffic away from congested segments of the highway so that it does not result in traffic jams. Criminals are often caught on camera doing what they do best, unaware that someone somewhere is watching them or their acts are being recorded as positive evidence to stamp them as guilty and bring them to justice. The largest human to camera ratio is probably in the UK where CCTV cameras are widely used for crime control and prevention. *Possible harmful side effects caused by public availability of such CCTV systemsThe widespread availability and use of CCTV cameras has a draw back in that they may be used by criminals to gather vital data about other innocent victims. Secretly installed cameras around ATM machines can track the pin number of an unsuspecting user and transmit the data wirelessly to the criminal. There is also the possibility that hidden cameras might be used by perverts to pry on their victims remotely or record them in compromising positions and use this data to black mail or extort money.

How Can a Cctv Security System Help?

Sat, 19 Jun 2010 22:38:02 +0000

One of the most frequently asked questions about the CCTV system is that inquiring upon its nature. CCTV, short for Closed Circuit Television, is a surveillance technology which monitors a wide range of activities and environments. The CCTV system is based on a communication link between a camera and a specific monitor. Many towns and cities resort to CCTV security systems, which has led to an unprecedented growth in the amount of money spent on surveillance systems. CCTV security systems are now used in public areas such as city centers, parking lots, public facilities, buses, taxis, phone booths etc. Actually, statistics say that the surveillance industry grows with up to twenty percent every year. CCTV security systems are also installed on private property, not just public places.

Evidence of domestic violence can be collected by means of a CCTV system, installing a camera inside the victims’ homes. A similar type of surveillance is used inside hospitals in cases of supposedly abused children, in order to monitor their parents’ activities and behavior.

In the early stages, CCTV security systems were used to decrease crime rate such as burglaries or car thefts. More recently, CCTV systems pick up on more minor offenses such as urinating in public, drunkenness, traffic violation. Those who evade the meters in a parking lot can also be caught on camera. Underage smoking, sexual or racial harassment, drug use, all of these crimes are the subject of CCTV system monitoring. Public order is now more likely to be kept with the use of CCTV security systems, which have become the solution to the serious problem that is urban dysfunction. But the police are not the only promoters of security through CCTV systems. Politicians also encourage installation of such systems in order to control crime.

The CCTV system also has its opponents, but whenever these critics speak up, people who are frightened by crime consider them to be nothing but enemies of everyone’s best interest.

As far as the technology used in a CCTV system goes, it suffices to say that some of these systems can be very sophisticated. They can be assisted by a computer, can detect motion, can have night vision and images of excellent clarity. Another amazing thing about the cameras on a CCTV security system is that they can focus on a single object from a crowded environment and follow that one object. They provide high definition images from which faces can be recognized. The time needed for a system to identify one face out of several thousands is less than a second. The system is mostly used in airports where terrorists may enter a country.

Since the CCTV cameras have often become targets of attacks, more and more of them now have a casing which is bullet proof, or are covered by other cameras installed nearby.

The question still remains whether CCTV security systems reduce crime. The answer is that they are most likely to prevent it. Those in favor of such surveillance systems have at least one argument. CCTV systems reduce the number of the so-called opportunistic crimes, that is the crimes committed when people decide to take advantage of a certain situation. In the same way, crimes in parking lots have reportedly dropped by almost ninety percent.

The conclusion is that, although CCTV security systems may not be as efficient as their supporters portray them, at least they appeal to common people, who now feel much safer when going shopping, for instance.

CCTV Surveillance May Protect You and Your Property

Wed, 06 Jan 2010 23:20:08 +0000

CCTV or Closed Circuit Television serves as ever vigilant eyes to different homes and business establishments.
A lot of people are setting up their CCTV surveillance system to boost the security of their home or business properties. The surveillance cameras will untiringly “stare” at the property and human traffic twenty four hours a day, seven days a week.
Fear Factor
After the 9/11 terrorist attack in the United States, the whole worls has been living in fear. Life seems to go on as normal but people are more conscious of the potential threats which somehow altered our concept of what normal living is.
Buildings have imposed tighter security measures. Public transport securities are not lax anymore. Security personnel have increased in number but it seems that this is not enough to make the public secure since security forces are only trained to react to something that happens along their line of sight but most crimes and offenses happen beyond their views.
CCTV surveillance cameras are playing a big role in comforting the public that someone is always watching them. Furthermore, the surveillance camera also serves as deterrent to criminal elements.
Making it Safe
CCTV surveillance cameras are place in strategic locations. They can be installed in the hallways, the lobbies, rooms, vaults, doors and all property parameters.
The surveillance cameras record everything that crosses its focus. The system tapes can then be reviewed and analyze in the event of a crime or incident. Sequential events can be recreated as time factor are noted by the system and all angles are viewed.
Security experts recognize the potential of CCTV surveillance systems to prevent terrorist attacks like that of the World Trade Center. The developers are incorporating new technologies to the surveillance system. Some cameras are equipped with motion sensors and some have face recognition program bundled with the system.
A Motion detector will trigger the camera to turn to the direction of the movement. The surveillance system can also follow the motion across a space. The individual camera will work as a team as they are triggered one by one by invaders of a property for example.
Face recognition advantage
Face recognition on the other hand is very helpful for solving crimes. The recordings can be reviewed to check the facial features of individuals and compare it to the database of the authorities. An individual that is identified to have a committed a lighter offense may be banned from entering the premises of the property.
Resolution and Night Vision
Other features that may be incorporated with the CCTV surveillance cameras are the clear resolution recordings and night vision. New systems can record crystal clear pictures with very recognizable faces. Infrared and night vision allows the system to capture the images even at night or at very low lighting.
Some surveillance systems have also incorporated cellphone technology. Homeowners or business owners can “call” a camera that is installed in their stores or home and they can view everything that is happening in real time. This technology allows them to zoom or pan the view of the surveillance camera with the use of their cellphones.
Due to the important role of surveillance systems, some states are requiring business establishments to install them as part of city ordinance.
