Interesting Facts About Camcorders
The portmanteau name of camcorder comes from the two words that describe it the best that is `camera` and `recorder`. It is a device that records audio as well as video images and saves it in its storage device.
Camcorders (filmadora) that initially used analog video tapes were earlier used for broadcasting of television images. They were huge in size, and had to be carried around on trolleys. However, as technology advanced, camcorders that could record digital videos started flooding the market, and soon by the 1990`s they were so small and convenient to use, that almost every home demanded one of these devices.
Camcorders (filmadora) consist mainly of three components: the lens of the camera, the imager and the recorder.
The lens is the `light path` of the camera that consists of a number of adjustments to allow the user to capture pictures and videos exactly as desired. These adjustments include parts like aperture (that allows one to control and adjust the light), the zoom function (that is used to adjust the field-view area covered by the lens), and the shutter speed (that helps capture any form of continuous motion).
The image, that could be called the camcorders `eye`, is used for housing the photosensitive devices. This is where electronic video-signal is developed from the light captured, in quite a complex electronic process.
The last section, that is the recorder, provides a number of signal-processing functions that help in copying the captured and developed video signals on the desired recording mediums (like the magnetic videotapes).
Camcorders (filmadora) operate on electricity and these days, most commonly they depend on rechargeable batteries. Therefore it is a must that you select your camcorder batteries well, and carefully, since they are going to be with you for a long time.
Camcorders (filmadora) come with a variety of features, some of the latest as well as the most popular additions being the flat LCD camcorder screens. Screens that can be rotated about 290 degrees along the vertical line, and horizontally about 90 degrees are also very popular among buyers, since they make video recording a luxury.
These days camcorders (filmadora) can be seen being used almost everywhere. Be it the electronic media that practically depends on this device, or the low budget TV shows that need clarity of images and sounds, in the most reasonable prices, or the political protestors who need to film images to prove things to the world, or the happy parents who wish to capture their newborn`s tantrums and feel proud.Camcorders are just everywhere!
Camcorders (filmadora) come with various price tags (starting form just about a few hundred dollars to over a thousand dollars), depending on the features on the device, the clarity of sound and images provided, the company manufacturing it, etc. Much of it also depends on factors like the format used by them (like the digital format or the analog format that are extremely popular).
However, regardless of the technology these devices may be using or how sophisticated its features may appear to be, camcorders (filmadora) are very user friendly and can be used by anyone. One of the most popular and user friendly applications of camcorder can be found in cell phones where camcorders are incorporated so extensively. However camcorders that are included in cell phones do not provide pictures as clear as the pictures provided by the camcorders.
Needless to say, camcorders (filmadora) have surely come a long way since it was first introduced in the market, and judging by the rate of its growing popularity, it can be safely said that these devices are here to stay for a long time and continue to develop and grow. Camcorders surely have a long way to go!

Everything You Always Wanted to Know About Wireless Hidden Cameras and Maybe More!
You are thinking about purchasing a wireless hidden camera but, like many people, are afraid of electronic products. You keep reading about words like “lux” and “camera resolution” and “line of sight” — do I really have to know what these mean? And, isn’t the wireless hidden camera hard to install?
The answer is NO and I’m going to tell you how easy it is to install and use your wireless hidden camera. I will also explain some of the “difficult” terms in plain, understandable English so you won’t be intimidated any more.
The best thing about a wireless hidden camera is just that — it’s WIRELESS! You won’t have to run any wires through your walls or under your rug.
These wireless cameras are called “hidden” because they are built into an existing everyday object that you see in your home or office. Most of these objects are functioning electrical appliances, e.g. clock radios, cordless phones, and even computer speakers.
Each object contains a wireless camera. The camera will function as long as the object is plugged into the wall outlet. For example, even when you turn your radio off, the camera is still working! These objects look natural when plugged into the wall, so your camera remains hidden and unsuspected.
Don’t forget — the object in which your camera is hidden is usually portable, e.g. clock radio. So even if you disconnect the plug from the wall — perhaps to move the object — you can still use your wireless camera with batteries. The batteries work for about 4-8 hours, so it’s best that you have another set handy or use a battery charger for a fresh supply.
You want to purchase a wireless surveillance camera system that is “Plug and Play.” This means just what it says — plug it in and begin using it! Your wireless hidden camera comes with 2 main components: 1) a camera and a transmitter connected inside an everyday object; and 2) a receiver which is attached to your VCR or TV. That’s all there is to it — you’re now ready to record!
Record what? There are unlimited uses for your wireless hidden camera.
How about as a hidden nanny camera — you can watch your children while they are being cared for by their nanny or baby sitter. What about your mother or father who is getting up in years and needs special care. Wouldn’t it be great to know who’s on your property all the time or even at the door? And how about your children — you can keep an eye on your tots with your hidden nanny camera to make sure they don’t leave the house or property. And, now with your small security camera, you will know the real time your teens return home at night!
By using wireless hidden cameras in the workplace, you will always be aware of what’s going on in your store, office and warehouse. Just set up a hidden camera to view your cash register, entrance and exit doors, loading dock, or just about anywhere.
All this and much more can be viewed from your VCR tape or live on your TV. And, with special software, you can watch what’s going on in your home or business on your computer screen, even when you’re away.
Should you choose a Black and White (B/W) or Color Camera? That is a personal choice that you should make. A Black and White camera does better as a low light wireless camera than a color camera because it has a lower lux. Color Cameras, however, would be more helpful to the police in identifying the burglar, shoplifter, assailant, etc. by giving a better description — for example, “the man with red hair in the green and yellow shirt.”
Finally, I promised to explain some technical camera terms. Here are some of the general questions you might ask about your wireless hidden camera:
• What is a Wireless Camera? A wireless camera consists of a camera with a transmitter attached to it and a receiver which connects to a VCR or a TV.
• What is “Plug and Play”? Plug and Play is the easy way to install your wireless surveillance camera system. Just connect the power supply (either AC for wall power or the battery pack) to your camera. Place the object containing the camera to show what you want to review. Connect the receiver to your TV or VCR using the red and yellow RCA cable from the receiver. You are now set up.
• What is a Transmitter? A transmitter is a device that converts video signals into radio frequency signals and transmits them as radio waves.
• What is a Receiver? A receiver is an electronic device that receives radio signals from a transmitter and decodes the signal for use as pictures on your VCR or TV.
• What is “Lux”? Lux is a method of measuring a camera’s sensitivity to light, i.e. it is the amount of light the camera needs to provide an image. The lower the number, the less light the camera needs to reproduce a clear image. A Black and White camera usually has a lower lux than a color camera. It will hold an image longer than a color camera. For example, a B/W camera with a .05 lux will be better in low light than a color camera with a .5 lux.
• What is the meaning of “camera resolution” for security cameras? Camera resolution is a measure of the clearness of a security camera. It’s determined by the number of horizontal video lines that the camera must have to reproduce the correct image. The higher the resolution number, the sharper the image.
• What is a Monitor? A monitor is what you use to view your camera image. The monitor could be a TV, CCTV (closed circuit TV) or even your computer screen.
• What is “Line of Sight”? Line of Sight means that the video signal travels from the transmitter in your camera to a dedicated receiver (e.g. VCR or TV) placed a certain distance away with no obstructions or interference between the two. The signal can go through walls and floors. Low Power Cameras usually have a line of sight of 700 feet. However, you can upgrade to a High Power Camera which has a line of sight of 3,500 feet.
So there you have it — you don’t have to be a camera buff to install or operate your wireless hidden camera. Just plug and play!
