The new Vivitar DVR can be purchased at the Vivitar company itself or online at sites like Best Buy or Office Depot. You can also check these stores in your area to see what they have available.

White balance is the term used to describe how does the camera balance the temperature of the image. As the name suggests, it's balancing the camera to the right temperature of color so that white is white.

Yes, usually through a USB port. You should check the operating manual of your camera. If you don't have it, try searching the manufacturers web site. When you connect it to the computer most of time your comp will search for software automatically and then you follow the directions given.

The monthly monitoring service is fairly inexpensive. What costs alot is the system itself and the installation of it. Sometimes you can find a special for free installation but the security system itself is expensive what you're paying a lot for.

Photography is always going to be called "photography"

Pictures are photographs that are framed, and therefore properly developed. "Picture" is the more generic term, and includes any kind of visual representation, whether it is drawn, painted, photographed or produced by some other means. You could even call a naturally produced image a "picture". The word picture can even refer to a memory or mental process that is by nature completely immaterial. "Photograph" virtually always refers to a physical image created with chemical or digital imaging technology.

By definition you can't detect them, or at least not without sophisticated electronic devices; and then only if the camera's output is transmitted wirelessly or the device is otherwise emitting detectable electromagnetic radiation.

That's the point of them.

There are devices supposedly able to detect roadside speed-cameras but it's easier, more reliable and safer to stick to the speed-limit!

photography is more than a medium..?

Organizations such as Wiki-how and Wikipedia provide great tips on wireless camera surveillance. The tips are very useful and easy to implement by the surveillance camera buyer. The tips are totally free and can be accessed online.

There are several popular companies that manufacture high quality mini wireless cameras, including Apple, Security Man, Alienware, Altec Lansing, Sony, and Samsung. These products can be purchased at select electronic retailers and online at Amazon.

The light will show on the film if its developed in the light

It depends on the size of the pictures.

If 1 picture is about 1MB, then 1TB= about one million pictures

A small picture may be 100KB, then 1TB= 10 million pictures.

Disk manufacturers make various claims which depend on the size of picture they think is typical.

There are a number of online retailers that sell IP video surveillance cameras. An example of a popular online retailer is amazon. Amazon has a large selection of IP video surveillance cameras, and offers free shipping on most orders as well.

One of the lightest digital camera is Casio EXILIM EX-M1 with its weight 86 g, but heaviest body has Canon EOS-1Ds Mark III - 1385 g.

With Canon body one you need some lens too, so with heaviest lens Canon EF 400mm f/2.8 L IS USM (5375 g), the total weight could be 6 kg and 760 g.

So broadly we can say, that digital camera is 0-7 kilograms.

Yes. I've seen the red light cameras in Maryland flash.

Serial numbers are usually on the bottom of the camera. They may be very, very small. Some less-expensive cameras may not have them. If you can't find it, check the manual in the warranty registration section. There should be instructions there for finding it.

There is no real answer to that, in reality cameras have nothing to do with image quality, lenses do. A higher megapixel camera however will give you better images, as it will let you see greater detail (not always a good thing, higher mpx can mace chromatic aberrations in lenses more noticeable, and thus you will need to buy more expensive lenses to fix that, also at high iso, noise will be more noticeable and in greater quantities)

The flash contains three basic parts.

First is something that produces light. Today that's almost always a flashtube, but there have been bulbs containing little pieces of magnesium foil and pans of a flammable powder called "flash powder." Underwater photographers still use flashbulbs because you can get ones that put out far more light than flashtubes are capable of.

Second is a source of power. Flashes can be powered by batteries or AC power.

And third is a capacitor. This is a component that can store electricity and discharge it all extremely quickly.

Because this needs to be semi-short let's just assume you have a battery-operated flash with a flashtube in it.

When you turn the flash on, you'll hear a little buzzing sound as the flash's power source charges the capacitor. It will store the charge until it is needed.

When your camera tells the flash to work, it will dump all the electricity in the capacitor into the flashtube. A big arc will happen inside the tube, which is filled with Xenon gas. When Xenon is exposed to this arc, it will get excited and give off a lot of light.

After this happens, the flash will recharge the capacitor and wait for you to take another flash picture.

Yes! Anyone can purchase and hook up a security camera kit. Simple instructions and a small amount of computer know how are just about all that is required.

Step 1

Write down the maximum focal length of the lens for which you want to find the magnification. For instance, a 70-250 mm lens will have a maximum focal length of 250mm. A prime lens will have only one value listed, and this value should be considered the maximum focal length.

Multiply this value by 1.6 if you are attaching the lens to a digital camera. Most digital cameras have a 1.6x "crop factor", which means that the outside edges of a scene will be cropped because they do not physically fit on the sensor, making the effective focal length 1.6 times greater than it would be on a film camera. For a 250mm lens, the effective focal length would be 400 (250 times 1.6).

Divide the effective focal length by 100. An easier way to do this is to move the decimal point two spaces to the left. The effective focal length of a 250mm lens on a digital camera is 400mm, so divide 400 by 100 to arrive at four.

Multiply this value by two to find the magnification of the lens in terms of viewfinder magnification used in binoculars or telescopes. So a 250mm lens would have an 8x magnification (400 divided by 100 multiplied by two) on a digital camera.
