Cctv Cameras

Most of all the areas in India are guarded by the CCTV security cameras today. Not only India but also other countries are greatly relying on electronic security systems rather than the manual security guards. When asked the general human beings, they suggested that electronic security systems are more trustworthy, more efficient and better guards the premises. Just few advantages and no one try to think beyond that. By seeing the positive aspects it is really very easy to get dependent on a particular security system but to think about the other side, it is really very difficult.

It is however a bitter truth that every coin has two sides that means, one has to tolerate the negative effects if one wants to enjoy the positive aspects. But having knowledge about the positive as well as the negative effects is important. So that before incorporating the products one should have a clear understanding regarding the material. It is an obvious fact that CCTV cameras are very beneficial in terms of security. It definitely guards the premise better than the earlier security methods but it also has possesses some limitations. Before acquiring the system you should obviously beware of the limitations.

CCTV Security Camera’s Limitations:

There are a number of limitations possessed by the closed circuit television in the premises, which the people should be well aware off. Taking into consideration of the general needs of people the various disadvantages that might result through the usage of CCTV security cameras can be enlisted as follows:

* If your security system provider is claiming that the CCTV cameras can solve crime then you can turn your back to them. This is totally untrue that CCTV cameras can be crime solver as CCTV cameras can only reduce the crime by capturing the on going scene. Then the one who supervises the camera can catch the suspect. Thus, it reduces the crime nothing is related to crime solving through CCTV cameras.

* If you are budget conscious and you want high resolution security cameras, then probably CCTV is not what you are searching for. With the increase of resolution in the image, cost of device increases and there your budget will fluctuate! After all better quality always comes with bigger price isn’t it! You need to readjust your budget for getting the best security devices.

* Complex cabling is just another disadvantage that comes with high resolution security cameras. If you really want to record the scene going on in the premises then you need to take the help of DVR (digital video recorder) systems. Associating DVR systems along with CCTV security cameras is a brilliant idea but cabling complexities and the problem of managing of the cables will always be there.

* How can you forget about the maintenance of the security cameras? It is not based on a single time installation charge factor, if someone is convincing you with the excuse that you need to install it for a single time and you are sorted then, they are misleading you probably. You need to maintain the device sporadically till you uninstall the system from your premise.

* The most important issue that is stated at last only so that you can easily guess the factor is the cost constraint. Entire story speaks everything, about how costly the device would be if you want the best among all. Nothing comes without costs so here come you are! You need to pay a bulk to achieve 100% security in your premises.

Do not get afraid after hearing so many problematic aspects regarding CCTV cameras. You can surely reach a particular security solution by taking the perfect guidance from a responsible firm who thinks about your willingness first. A high resolution security cameras provider company can always guide you through and thereby you can always meet your security expectations. Then, why not to grab the chance!

This article will attempt to reveal some of the more common mistakes to avoid when creating your own CCTV DVR.
Budget: Many DIY’ers simply do not budget enough money for projects like this. When looking at cameras, look at the specs. A $200 security camera and a $50 security camera are going to be very different in terms of image quality and light response. Also look at CCTV DVR features. Places like Costco offer surveillance systems for under $500 but those surveillance systems don’t have anywhere near the features of professional grade systems like Video Insight. Those systems can even be missing basic features like video motion detection. You may want to look for surveillance packages that combine everything you need to put a system together, including the CCTV DVR, security cameras, security camera lens’s, mounts, power supplies, and cable. Packages like that can start at about $2000 and go up to $10,000 depending on the number of security cameras needed. Surveillance Camera Placement: Surveillance camera placement is one of the most important factors in an effective surveillance camera system. Ask yourself the questions professionals do: How is the light coming in? How will this change at night? What am I trying to see? How do people move through the area? What kind of blind spots will there be? What kind of surveillance camera lens do I need to use? Do I need to use multiple surveillance cameras to cover this area? Would a side view be better for this then a straight on view? Selecting the right security cameras: When looking at security cameras, understand what you are trying to do. Are you looking for license plate recognition? If so, then you need to select a camera lens that will allow the plate to be at least 1/3 of the image. This means that a surveillance camera with a wider field of view can not do license plate recognition. The same goes for ****** recognition. If you are trying to cover a parking lot with a narrow entrance, you will have to use two surveillance cameras. Very wide entrances can make this very, very hard. Selecting the right camera lens: Selecting the right camera lens is pretty easy. Note where you are going to place the camera and select the point where you want the best picture. Measure the distance from there to the camera. That is your focal distance. Then measure the width of the picture you want to see. Once you have these numbers you can feed them into a CCTV lens calculator. Looking at the F-stop will give an idea of how well that lens will work at night. Infrared or No?: Infrared cameras are wonderful for covering areas of complete darkness. But many of the all-in-one camera/emitter units are fairly limited in range. This chart can help with deciding if you need to go the infrared route or not. Direct sunlight: 100,000 – 130,000 lux Full daylight, indirect sunlight: 10,000 – 20,000 lux Overcast day: 1,000 lux Indoor office: 200 – 400 lux Very dark day: 100 lux Twilight: 10 lux Deep twilight: 1 lux Full moon: 0.1 lux Quarter moon: 0.01 lux Moonless clear night sky: 0.001 lux Moonless overcast night sky: 0.0001 lux Focusing the video camera: This is a simple and easy trick to help with focusing the video cameras. Use a BNC to RCA plug and a small television set to focus the video camera. The ideal time to focus the video cameras is in twilight because it will give the best compromise between the light and dark settings of the auto-iris lens. Cable types: There are a few types of cable called RG-59. Copper vs. Aluminum sheet and 75% braid vs. 95% braid. For CCTV system work, you should always use copper shielding. Aluminum shielding is meant for modulated signals like cable and allows too much interference for CCTV systems. 75% braid and 95% braid measure how tightly and how much copper is used in the copper sheathing. 95% copper braided cable is more expensive but worth the extra expense. It is much more effective at preventing interference, and much more forgiving of mistakes. We only sell 95% braid copper shielded RG-59 Cable runs and Ground loops: Coax cable should be kept at least 12″ away from any power lines and power conduits. The AC power creates a field of interference that will appear like snow on the screen. This can create havoc with motion detection. Ground loops can be caused by securing cameras to metal structures that have a different electrical ground then the power supply. This will cause bands to move through the screen. Solving this is a matter of eliminating contact between the cameras and the source of the ground. Sony Cameras: Sony has a line of CCTV surveillance cameras, but all of them are clearly marked Sony. You will see a lot of sites offer “Sony” cameras when they don’t say Sony on them. The reason for this is that Sony makes about 75% of the worlds CCD chips, which are used in everything from Camcorders to digital cameras to CCTV security cameras. The CCD is an important part of the security camera and has an impact on the resolution, but the electronics behind the CCD also have a big role in how good your image is. What determines how good my image is?: How good your image is depends on quite a few things. It depends on how good your lens is, how well it is focused, what the resolution is, and how good the S/N (Signal to noise) ratio is. When looking at a camera, you generally want both the highest resolution and the highest S/N ratio you can find. The Signal to noise ratio is a Logarithmic scale so the difference between 46 dB and 48 dB is a rather large difference. If forced to select between a camera with a slightly lower resolution and a high S/N ratio or a camera with a higher resolution and lower S/N ratio, try to select the one with the better S/N ratio if you are doing longer (500 ft+) cable runs. For shorter runs going with the higher resolution is okay. How many FPS do I need?: Many manufacturers and distributors will try to push their highest frame rate DVR’s and Cards on you because those items have the best profit margins. But high frame rates may not be in your best interests from both a storage and budgetary perspective. For most applications 3 to 7 fps is fine. If your goal is to identify theft or vandals then 3 fps is almost always enough. The only time one should consider more then 15 fps is if you have to watch for sleight-of-hand like watching a register. The reason to avoid higher frame rates is that they take up more drive space, reducing the total storage time of the system. It can also divert budget away from selecting the right cameras which is far more important and more likely to generate usable evidence then a higher frame rate. Audio Recording: Don’t do it! In many states it is illegal, period. It does not matter if it is your home or other private property. The law only cares about if the people being recorded are aware that they are being recorded. A number of people tend to think “Well, I’ll put it in anyway, it’s not like someone is going to report me.” The problem with that line of logic is that if you ever submit video as evidence to a court and you are in violation of your state’s laws or federal laws, then you have just given proof to the courts that you also committed a crime. The best possible outcome is that the court throws out the recording and you don’t go to jail. But if you can’t use your recordings to help convict a person that has wronged you then what good was the money you spent? CSI: As a general rule of thumb, anything you’ve seen done on television or in the Movies with video enhancement is simply not possible in the real world. You can’t make data appear where there is none. There is no magic trick to make that work.

As the use of CCTV cameras increases across the United States and globe, so does the debate over their numbers and motives. There are many arguments for video surveillance, including peace of mind, loss prevention, crime deterrence and crime solving, but what about the other side of the story? Thousands of individuals and groups oppose video surveillance, and many of them have extremely valid points. What are the consequences of allowing “Big Brother” access to our entire public life? Will that eventually lead to the invasion of our private going-ons? When does it begin to be too much? The ACLU has an entire Web site, You Are Being Watched, devoted to the “high costs of camera surveillance systems, both in terms of money and civil liberties,” and that is just one example of a group that is taking action.

So, what are some of the main arguments against the use of CCTV surveillance systems? Lets see…

Invasion of Privacy - This is the most common argument against surveillance systems. No one likes the idea of being watched, but yet we are starting to see security cameras on many more street corners and light poles. Cities normally justify these additions by saying they are monitoring and preventing crime, which is valid, but many people, both innocent and not, would rather the cameras not be there. While video surveillance is more commonly accepted in public areas, this sentiment comes into play more so with the use of covert and hidden cameras in private areas. Laws enforce restrictions in this arena, for now, but the main concern is the future of citizen privacy.

Mistrust – The use of security cameras in your home or business can make its occupants feel mistrusted. If your family members or employees are under constant surveillance, there is likely to be hostility and animosity in the air. Feeling like every move you make is monitored and recorded is not only creepy, but downright scary. Even the most trusted employees can become paranoid and nervous when a camera is pointing at their cubicle all day. No more dozing off, checking facebook, text messaging or doodling, you are being watched!

Not Proven Effective - Studies done in California and London have found that security cameras had little to no effect on reducing the crime rate. With an increase in the sheer number of cameras in many large cities, many replacing human security guards, this is a strong argument that will be the main target of many opposing groups. I think we can all agree that there is no replacement for a thinking, acting, problem solving human police officer or security guard, and if we begin to rely on cameras as pure deterrents, how do we plan on stopping crimes as they are happening?

Misuse and Abuse - The footage captured by CCTV cameras becomes susceptible to abuse and misuse by those who have access to it. For instance, the footage can be used to discriminate against people and for voyeurism. In the age of the Internet, this is another huge deal, as can be seen by all of the “hilarious” YouTube videos out there. I doubt the subjects would find most of them as funny. This obviously ties into the invasion of privacy issue, and is one of the primary concerns of activists. All it takes is one “funny guy” security guard to post footage or still images of an individual doing something embarrassing or that they shouldn’t be and reputations are ruined, privacy is obliterated and those that oppose CCTV will have more ammo.

All of these reasons are valid arguments against CCTV surveillance. There are many cities and countries that have massive surveillance systems, and we will likely see a large increase in public monitoring in the near future, so the more the public knows about the industry and their rights, etc, the more everyone can prepare for when it happens in your little corner of the globe.

Do you have any additional arguments against the use of security camera systems? What are your thoughts? Will you fight them or open your “public” life up willingly to being observed? Feel free to leave a comment with your thoughts and opinions.

CCTV surveillance cameras are one of the necessities that a home should have. The crime rates in a lot of cities have reached an alarming level. A lot of robberies have happened which at times includes murder. A surveillance camera has been proven to be quite effective in keeping the safety of one’s family and property. Having a surveillance camera in one’s home can help identify the culprit. Not only that, it can also help stop an ongoing robbery or at times even prevent it.

It has been proven that crime rate have decreased and it is all due to CCTV that are installed in critical areas. This has been quite effective in stopping criminals from targeting some homes that have a surveillance camera. If you are one of those individuals, who values the lives of their families and their properties, then a surveillance camera can be a very wise investment. Criminals would definitely think twice before attempting any robbery at your area. This is due to the fact that police responds quickly upon requests of operators for assistance in your area.

There are a lot of cameras out there but a CCTV system is one of the best. It price does vary upon the needs of a buyer. If one needs only a single camera then one has to expect to pay $100 or more. This will also mean that the more cameras will be installed then the price will have to follow. One can expect to pay a thousand dollars or more for numerous security cameras that will installed in your property.

Huge expenses can be lessened. This can be done by first identifying what part of your property is more prone to possible forced entry. A sufficient lighting and the proper installation of the camera can prove to be more efficient. It is also wise to install CCTV surveillance cameras in areas that do not have sufficient lighting. Since it is a fact, most robbers and thefts look for entry ways that are less conspicuous and quite dark. If one has one of these security cameras, they can sleep more soundly at night and can go on a worry free vacation.

Hidden Cameras are covert camera devices that are used to keep surveillance over a particular area. They are usually installed at hidden places or cleverly disguised in other unsuspicious articles. The camera continuously records images in its field of vision, which can be retrieved and seen on a computer or TV monitor. Both simultaneous as well as recorded telecasts are possible.

The major use of Hidden Cameras is security. Almost all department stores, banks, hospitals, airports, casinos, etc. have Hidden Camera security systems. These cameras are connected to a monitor in the security cabin, which is continuously manned. Several cameras can be hooked onto the same monitor forming a CCTV network. CCTV Hidden Cameras are very popular security devices.

For home use, smaller Hidden Cameras are available, which are also called as spy cams or nanny cams. They are installed at secret places inside the homes so that people can keep a watch over their children’s nannies or caretakers of senior citizens while they are not at home.

Earlier Hidden Cameras used to be big devices which were not easy to conceal. But present-day cameras are so small that they can even be disguised as a shirt button. The most important component of the camera is its lens, which must be kept clear so as not to obtain muddled images. Lenses are available in miniature sizes so that the size of the camera itself can be very small. The beauty of a Hidden Camera is that it can have a clear field of vision without itself being seen.

Hidden Cameras also have many other uses. Such cameras are installed on traffic signals in order to control traffic. People running down signals can be nabbed by viewing them on the screen. Even impending accidents can be avoided.

However, the use of Hidden Cameras is also a controversial issue. Many people think a Hidden Camera is an invasion of privacy. Though Hidden Cameras have managed to book several shoplifters, the very aspect that Hidden Cameras treat everyone as guilty is gaining controversy. Another major controversy is the use of Hidden Cameras in private places such as hotel bedrooms and restrooms, and using the images for pornographic purposes over the internet. The use of Hidden Cameras is bound by several legislations, which differ from state to state. Despite that, Hidden Cameras are being progressively used all over the world for security and crime prevention.

Donald Carmin asked:


With the identification of the spy cams, the hidden cameras the concept of surveillance has totally changed. Today every independent or a collective business or any other organization needs proper care and attention. Protection and analysis of every organization is very important and that has to be done with the help of new and modern hidden cameras and only then the highest peak of success can be obtained and achieved easily. We have to understand the logic advantages of such types of cameras and how far they can help us in most probable ways. If the hidden cameras are installed in the various sectors of the banks, then the process and the transactions can be surveyed and identified in an appropriate manner. They can even be installed in the ATM centers, the hospitals, the shopping malls, the theaters, the highway roadways, the air ports, in the railway stations and many more places.

Surveying the surroundings with the help of these hidden cameras can reduce our work and time to a big level. A quick look can be taken at the video in which the information is gathered with the help of the hidden camera and then we can take action against the problems if they are any. It is a very familiar type of equipment but it is loaded with additional advantages and features. They are available with different sizes, colors and models all with reasonable rates. They vary from size to size. They are small neck tie or wrist watch sizes to big sizes. But we cannot undermine even the tiniest camera. It has its own style of working and giving services. Recognizing the kind of camera is very essential before we buy and make use of it. Nowadays it is not as difficult as earlier to buy anything directly from home. Sometimes we do not get time to go out for shopping and have a look at the new products which are available in the market with whose help we can change our working techniques. We can surf through the internet and gather all the information about all the latest products which are available. We can have fun shopping through the internet. We have to log on to the top websites of the country and place an order for our requirements and relax. Our product will be shipped to us within a few days. This is indeed a sporty way of choosing the product.

In many places people try to break the traffic signals and they also try to create stunts near the railway tracks. There was news in the television describing about how a lady was driving a car and crossing the railway track speedily without waiting for the train to pass. She was trying to create stunts in a dreadful manner. Fortunately she had a narrow escape. The CCTV cameras were on and her actions were captured and she was punished for her behavior. People who try to create such disobedience have to be observed and punished so that they do not create problems again. The uses of the CCTV cameras are truly appreciable.

Estephen Dolano asked:


For a well balanced and leveled function of any work, we require good devices at our aid. If we can manage to collect all the information of the latest devices which cover the market with great enthusiasm then definitely we should and then buy those devices and make the most use of them. The CCTV cameras, the hidden cameras and the spy cameras are some of the latest and innovative devices which are out in the market for us so that we can make use of them as we like. Apparently these cameras are used for surveillance purposes, but we can even use them for our excitement. Nowadays carrying a camera along with us anywhere is not at all a burden, rather it is very easy and it can be a fun using a camera where we can. When we are going out for the parties, picnics or to attend any other occasion, then we can easily carry our own camera along with us because they are available in many small sizes too. If we are on our way to some investigation against someone, then too the small cameras can be easily used for the same purpose. These cameras are so small that they can be fitted easily in the wrist watches, the pens, the sun glasses, the cigarette cases or even the mobiles. Either the camera is small or big, but the functions of all the cameras are extremely advantageous. These types of small cameras need no receivers or wires. They are wireless. The DVR pen spy cameras are geared up with the ability to record simply like any other camera or the camcorder can record anything. This is done efficiently using the 4GB of memory power. After the recording using the pen spy camera is done then we can even view all the information gathered in it with the help of the video by just plugging it into the USB device. Furthermore this 4GB memory camera has to power to store video recordings of about almost 30 hours. The battery of this pen spy camera is easily rechargeable and has the power to record the events for almost 2 hours.

Today in fact everything is available easily for us and all the equipments are loaded with many advantages which can help us to finish our work instantly. It has become relatively simple for us to gather the information of these types of equipments through the internet also. We can simply surf with the website and go through all the information about the various appliances and equipments which can help us in many ways. We can also buy our products online with the help of the internet. We have to select our product, place an order with them and they can easily ship our product to our place. The upgrading of our equipments has becomes indeed very important for all today. If we want to move ahead in our life with challenges, then we have to make use of the equipments like the cameras so that we can easily survey all the whereabouts of the measures which are taking place around us.

John Velazco asked:


The size and nature of business or any other work plays a very important role in making the choice of surveillance. Today there are different types of outlets all over the world such as the departmental stores, multiple shops, speciality shops, general stores, chemists, grocery shops, malls and many more such business establishments where security has to be taken care of man people who visit these outlets all through the day. Large scale business organizations can use large hidden cameras and small business organizations can use small hidden cameras or the spy cams for surveillance. A business man will always prefer the safety of his environment. Today new technologies are been introduced and these technologies enable various functions and integrates the entire system to get the desired results at the places where they have been installed. The manufacturers were in a way to produce various equipments for the comforts of the people. They were working keeping in mind the requirements of the individuals. The emerging equipments needed to be carefully analyzed for the functionality, stability and the value it will bring into a system after implementation. The manufacturers worked up with giving us these fabulous equipments with the name of the hidden cameras or the spy cams. In addition to external challenges, people are also faced by some long lasting internal challenges and these internal challenges or disturbances in the environment created by the staff members. In some firms there can be interruptions and for the surveillance of such interruptions the hidden cameras can be installed to avoid the same. With just a click of a button we can have the integrated system at our aid.

The different types of cameras, tools or the technologies which can be used by the individuals for surveillance are the CCTV cameras, the CID cameras the CMOS cameras the CCD cameras and many more. All these cameras can be easily available in all the leading websites of the country through the internet. All we have to do is to decide about the type of camera we require and we have to place an order for it through the internet. Our product will be shipped to our place within a few days.

These CCTV cameras store all the needed information digitally and retrieve the same digitally more conveniently as compared to hunting for the right tape in CCTV. Many areas where all the leading malls and stores all over the world have caught up with the technological curve is in surveillance through these type of cameras. These are really good equipments which can bring changes in our way of ding the work at our work place or even in our house. If your wife is a working lady and she has to go out the house for the job, then obviously she has to keep her children at home with the baby sitter, so this way you can get the spy cam installed in the house and can easily keep an eye on the movements of the baby sitter at home in your absence.

Camila Machuca asked:


Today we are aware of the superiority of present tools which are intended to give us full assistance whenever and however we use them. Even we cannot deny the fact about the rising crimes all over the world and the administration and the other higher authorities are constantly worried to find the way out to the solutions to all the rising problems. They wanted ways where they could give complete security to the citizens and then they found out revolutionary ways where they could give security to the citizens and protect them from the entire crimes which often take place in all the parts of the world. Yes, they recognized and got familiar with the beneficial hidden cameras, the spy cameras, the nanny cameras, the CCTV cameras, the CMOS cameras, the CCD cameras and several other cameras which can be used for supervision dealings in all the fields of work. Earlier the hidden cameras were used only by the administration in some of the important places where people would likely gather at large, like the airports, the railways stations, the taxi stands, the auditoriums, the universities and so on. But these days almost every individual is opting to buy these hidden or the spy cameras so that they can protect their belongings by themselves and even secure themselves always.

I would personally like to share my distressing experience and how thereafter I regularly carry a Wireless Spy Camera along with me always. I still remember the dreadful date (October 2, 2007) when I completed my work around 10p.m. something not too late by today’s’ standards of life. I thought I’d meet my friend for dinner before heading home. The city had been home for me since a past few years and I didn’t even think to sitting in the edge of a cab enjoying the view of the glittering city with the glass of the cab open least knowing that there was a accident awaiting for me at a traffic signal as soon as the driver pulled light near the signal. Suddenly, there was a blur as a man in white shirt approached. Before I could realize what was happening, he attacked me with a razor-sharp object and slit open my wrist. When I looked down, even my shirt bore a cut near the shoulder. I was shocked. The cab driver pulled up the speed and took me to my friend who was waiting for me just five minutes away from the spot. The wound required four stitches. The next day, I went to the police station to register a complaint. They asked me to draw a rough sketch of the culprit but the incident had occurred so quickly that I could not recollect his face. After this another routine interrogation followed but they could do little without sufficient details about the culprits. It was then I realized that I should thereafter always carry a Wireless Spy Camera along with me so that in future if God forbids I would have to face the same incident then I would easily capture the image of the culprit. This spy camera was the ultimate solution to all my problems.
