CCTV Camera Systems- The Benefits

A CCTV or a Closed Circuit Television has many uses and related benefits. They are widely used in offices and government offices so as to keep theft at bay. It helps the police as it gives them substantial proof and helps to keep a close eye on the employees.

Fact is that having a CCTV is necessary in today’s day and age. If your company, store or business organization is well-known, chances are that your employees are under constant threat. When the situation is dire and stress cannot be avoided, a customer may attack your representative. However, if they are informed about the CCTV camera systems, they will be careful and calm at all times. In addition to that, employees are also protected against such untrue accusations or allegations that can cost them their jobs.

A CCTV camera is mostly used to keep crime at bay. Since the store or building is under constant surveillance, people hardly ever dare to indulge in such activities that will get them into trouble. In case they take a chance, it will be recorded onto the camera and make it easy for the authorities to capture the culprits. Therefore, it helps to prevent as well as catch the crime.

These cameras help to prevent theft which is rampant no matter what the nature of your business is. Apart from customers, sales representatives tend to shop lift as well. When your employees know that they cannot get away with it, they will not take a chance. When proprietors are looking for ways to increase productivity levels by enhancing employee satisfaction, they use a CCTV camera to find out what irks their employees and what gives them incentive to work harder. In this case, it is recommended to keep the CCTV Cameras hidden because if the employees know that they are being watched, they will always be on their best behavior which will negate the entire purpose of installing them.

When seen from an employee’s point of view, a CCTV camera is considered to be unethical because it invades their privacy.  A CCTV camera can help to catch lies. For example- if your restaurant has been accused of poor health standards and your waiters insist that it was not their mistake, you can watch the recorded footage and form your opinion. It will also help you to ensure that safety regulations are being followed.

Hobart CCTV and Canberra CCTV systems are well-equipped and make use of top of the art technology to ensure that your security needs and taken care of. The company representatives are helpful and will answer your queries in great detail. Their respective websites will give you the required information, giving you enough background information regarding the company’s reputation.

Even though CCTV camera systems are beneficial in most cases, a number of limitations have been discovered as well. For example- if one sprays a certain substance onto the surface of the camera, it becomes difficult for the authorities to point out significant details.

How to work out what (37mm) wide angle lens is needed?

I have a Contour HD POV camera which has a FOV of 110 with 1080p and 135 for 720p, etc.
I am able to purchase a step up ring to allow me to use 37mm filters. I am interesting in increasing the FOV with the use of a 37mm wide angle lens to something wider (preferably without vignetting or too much of a fish eye effect)

The angle of view on those cameras is already very wide. If you add the 0.45x adapter to the 110 deg field of view, you will have a field of view of 159.5 degrees. That is extermely wide, and will introduce noticable distortion. At 135 degree field of view, you would be up to 195.75 degrees… well past a fisheye. Massive distortion, and probably a good amount of vignetting.

Vignetting will depend on the adapter itself, along with the adapter lens.

If you are like one of an estimated 75 million owners of a digital camera, at some point in time, your camera will more than likely develop one or more problems and would be in need of digital camera repair. Common problems include cracked LCDs, broken battery doors, jammed lenses or board level problems.

There are a set of digital camera models however, that develop their own unique problems, all stemming back to a batch of defective CCDs that Sony produced and used in these camera models.

To start with, what is a CCD? A CCD is a Charged-Coupled Device, that “enables the transportation of analog signals through successive stages and are used as a form of memory or delaying samples of analog signals”.

Now for that in English: In the digital camera world, CCDs are used by the camera to capture the image that is shown by the lens, translate it into a digital signal and send it along to the image processor to be converted and saved to the memory card.

What’s the big deal with the faulty CCD? Well Sony produced a series of CCDs for various digital cameras between the years of 2003 and 2005, for at least 20 different models. And in higher heat and humidity conditions, the CCDs would begin to fail, producing some crazy looking images or causing a black screen to show on your camera (Before you starting thinking your camera has a bad CCD, PLEASE check and make sure your “display” button is not pressed and just shutting the LCD off).

So what does this mean for the consumer? Simple: If you own a camera that is covered under the Sony CCD recall, and your camera develops a problem as described above, you can generally send your camera to the manufacturer and get the CCD repaired for free. The largest affected manufacturers are Canon, Konica Minolta(now part of Sony) and Sony, but luckily for consumers, these manufacturers are standing behind their products and fixing their faulty CCDs. At one time the manufacturers were just replacing the cameras with new models, but lately it seems, they have gotten the CCDs fixed and are replacing them for you. Same camera, but you get a new, updated CCD and many more years of memories!

As Sony is the original sensor manufacturer for all of the other manufacturers’ products listed (and given the vast array of products that they manufacture themselves) it should come as no great surprise that Sony has by far, the greatest number of affected products. This should not be taken as indicating any inherent deficiency in Sony products beyond the now discontinued sensors.

Don’t throw your digital camera away if it has a bad CCD and it is covered under this recall, get it repaired for free! The best part about having the manufacturer repair your camera under this recall is that they will inspect, test, calibrate and update the camera as well as replacing the CCD with an updated version that will not fail as the first one did!

If your camera takes only solid black photos, or blurry pink/purple photos, call your manufacturer and ask them if the camera is on the CCD recall list today! If your camera is on the CCD recall list and you do not have this problem, YOU WILL in the future, so get it repaired now before the recall ends!

Applications of Vehicle Security Cameras

Vehicle Security surveillance Cameras operate under any ambient lighting condition, ranging from total darkness to direct glare from sunlight and high beam headlights, at speeds of up to 100mph. Nowadays, the technology of surveillance cameras  implies applying all matters and procedures of security to be used in cars and all types of Vehicles.

Regarding the recurrent criminal acts that occurred in public buses and cabs, the need for using a security systems are connected to police stations, where police officers can receive signals or electronic messages in case an incident happened. Now, what are vehicle security cameras? How can we use such security cameras? Where can we install them? What about passengers and transportation customers, should they know that they are monitored each time they get into a bus or a taxi? And what about violating privacy?

Vehicle security cameras are a modern innovation in the world of surveillance industry. USA laws had come up with installing these cameras in all cabs, buses and metros in order to sweep security and surveillance cautions and precautions in all public transportations, and as a result they have more control over the states security systems, thus they eliminate the average rates of assaults, encroachment or other homicidal acts. These cameras should be manufactured with high-quality features. And herein, a list of the most common and important features of vehicle security cameras.

Auto White Balance

AWB allows your camera to remove unrealistic colorcasts so that objects, which appear white to the eye, are rendered white by your camera. An incorrect white balance can cast orange, blue, or green hues onto your image.

Automatic Gain Control

AGC adjusts the video so that a more consistent level of brightness is achieved. The signal is fed back to adjust the gain to a median level for a range of input signal levels. If the brightness is weak, AGC boosts it. If the image is too bright, AGC reduces the brightness.

Back Light Compensation

BLC is useful for adjusting the brightness of an image. It is specifically video gain used to correct the exposure of people or objects in front of a bright light source, which causes the subject to appear as a silhouette. The prime example of when this feature is needed is when a person is entering through a doorway and the light from behind him makes his image dark. With BLC, his image is corrected for proper illumination.

CCD imager

A charge-coupled device is a specialized type of integrated circuit located behind the cameras lens. The lens focuses a small image of the scene onto the CCD imager, which scans the image and, with the help of other electronics, converts it to a video signal for use by a DVR or Monitor.

CS Mount

CS mount is the industry standard lens mount. It differs from a C Mount in that a CS Mount has a flange focal distance (FFD) of 12.5 millimeters while a C mount has a FFD of 17.5 millimeters. An FFD is the distance from the mounting flange (where the lens comes in contact with the camera) to the focal point. A C Mount lens is compatible with a CS Mount camera with the addition of an adapter ring, called a C ring.

Infrared

IR is the spectrum of radiation just beyond red light in the visible range and below microwave radiation. Night-vision cameras come equipped with IR lights, which allow the camera to see without any light source.

Lux

A lux is an International System of Units for illumination equal to one lumen per square meter. It is a measure of apparent intensity of light hitting a surface. A lumen is the measure of perceived power of light.

Wide Dynamic Range

WDR doubles the exposures per frame and controls the length of time that the Automatic Electronic Shutter is open. A short exposure and a long exposure image are taken by the camera. The resulting two images per frame are then combined so dark and bright areas are reproduced clearly, with detail in both bright and dark areas. In this way, the bright areas are not too washed out and the dark areas are not too black.

Vehicle security cameras can be installed either at the inside head of the vehicle or at the back, and wither ways, police can guarantee that the driver and the passengers are fine, and keep track on them if something goes wrong.

Regarding the passengers privacy, I think, according to the state’s security laws, the driver should past a notice on a seen place where all passengers can read and know that there is a security camera, either visible or hidden, in the car, or the bus. Thereupon, by getting in the bus to move to the other station, they approve to be monitored and observed all the journey long, and accredit the agreement to use the recorded videos as a court evidence in case of a criminal act occurred.

My eye side is bad can’t see sharp through my camera . Can I get a camera with a special lense put in?

Does anybody has a solutions and can help me to see sharp through my camera again. I plan to buy a quite expensive professional camera and wonder if it could be prepared specially for my bad eye sight?

All DSLR’s have a dioptre adjustment in the viewfinder, in extreme cases an adjusting lens can be added. Your optician will make you an add on prescription lens should that be necessary. I know that Pentax make eyepiece holders for their cameras that take these lenses.

If matter comes into contact with anti-matter on Earth, it will annihilate and then, what happens to energy?

Will it become electro-magnetic radiation, get absorbed as heat into the universe, form gamma rays?

they will annihilate each other and leave as particles with equivalent energy…

What Is Ccd In A Digital Camera?

The CCD (short for charge coupled device) camera is the optical sensor, which is the component that allows to transform the image from the objective into electricity and then into a video signal.
This is a relatively recent invention (Boyle and Smith in 1970) that revolutionized the world of television cameras, moving from bulky and expensive equipment to ever more compact and economical consumer products.

How does a black and white CCD work?
A camera has a lens that is capable of receiving the external light and recreate an image upside down at its focal point. At this point it is ranked the CCD.

It is composed of hundreds of thousands of microscopic units called pixels arranged on a precise grid gives each a vertical coordinate and a horizontal.
Each pixel is able to react to light which involves storing a certain electric charge.
The charge of the various pixel is read continuously (with a frequency variable adjusted the convenient electronic form) from a signal processing circuit, which is constantly aware of the amount of light that hit different pixels and is capable upon this

How does a color CCD work?
In the case of color CCD camera, the thing is a bit complicated
To achieve a color image is not enough just an indication of how much light strikes the CCD but also that of its color components. The cameras film cameras professional 3 CCD used for this purpose on each of which are projected components of green, red and blue image separated by a prism. This solution is however very expensive and is not for this use in CCTV. Conversely this is replaced by a device to allow a single CCD “understand” the colors of the image.
To make a color CCD camera is placed a grid on the CCD filter, where each pixel represents a filter to allow the passage of only parts green, red and blue.
An example of grid filter can be seen in the picture on the side. It is noted from the drawing that the number of green filter is twice the red and blue filters (25% blue, 25% red, 50% green) because the human eye is more sensitive to this color component.
What in the CCD monochrome er a pixel, it becomes rather an area in the color CCD for detection, said quadrant, consisting of two green pixels, one red and one blue. The circuit of the camera will only mix these components to derive the final color of that quadrant.
As you saw, where the CCD used a black and white pixels, the color CCD camera only uses 4, this explains why the cameras in black and white rule have a much higher resolution cameras in color.
