Improving Home Security With A Personal Computer
In the computer era today, personal computer is more than just a tool to accomplish office tasks or to play games. There is actually a close relationship between information technology and home security, since you can use your PC to help you protect your home. With computer, many security tasks can be done automatically.
In the past few years, the traditional way to record an access violation is to use video security equipment by connecting video cameras to a TV and VCR. The VCR will then record everything captured by the video cameras. As the price of a VCR is quite low today, you can use it for security purposes at a little cost. There are also magnetic media-based recording devices with a time-lapse recording feature. This is useful to extend the time in which the device can perform recording.
You can also perform the job by using your own PC easily. In this case, with the help of surveillance software, the computer can record any events digitally. It differs from VCR, you will be able to save captured videos in a digital format which is easier to archive and edit. Moreover, such system can also be set up to start recording when it detects any movement.
There are many other advantages of using a PC as a security system. Today's modern PCs are designed to be able to get connected to various devices. For instance you can connect spy cameras to your PC and perform covert surveillance. With a video capture card to convert analog to digital signals, this system can be set up very quickly. If you want you can even use the web camera that you usually use for chatting to perform remote monitoring and surveillance.
Using your PC as a surveillance system doesn't mean that you have to stay in front of a computer to get an immediate warning when there is something bad in your home to occur. Some types of webcam security software even provide SMS-alert facilities. This permits you to use your cellphone to get an instant warning if there is an access violation at your home.
Depending on the software you use, there are various types of security tasks that can be accomplished with the help of your PC. For example, you can make your PC sound an audible alarm whenever it detects a motion near the door or window of your house.
However, if you want to use your PC as a home security system you should spend enough time when selecting the software package. Although most brands of software provide similar features, there are some activities that can only performed by a particular brand. Some brands of software are more expensive than others, but they likely provide a higher degree of protection.
An affordable PC based security system like this is especially useful when you are not at home. For instance, when you are at work or are on a vacation. This system allows you to concentrate on your tasks or to enjoy your vacation away from home, because it will send you a notice instantly of something undesirable happen in or around your home.
Best Cell Phone Spying Software – All You Will NeedThe Video Camera Reigns Supreme
The video camera first made its debut in the television industry but has now penetrated the common field. BBC (British Broadcasting Company) used the first ones in the 1930`s.
The video camera is used mainly for two purposes. The primary one is for projection of live shows, like the ones we see on the television as also for immediate spying as used by and for the military and industrial operations. The second purpose is for storage and archiving. Videotapes were at one time in use but now discs have replaced these.
The latest video cameras (filmadora) are a far cry from its first generation models - similarities are difficult to trace. Professional models of video cameras are mobile units and allow fine manual control as required in fieldwork. Camcorders (filmadora) are also video cameras - it is a combination of a camera and a recording device (VCR). These are in great demand for home movies, television production, electronic news conferences etc.
Another type of video camera is the closed circuit variety that is used for security and monitoring. They are tiny so that can be hidden and are often used to monitor the environment in settings where man cannot physically go. These web cams are video cameras used where there is danger from radiation, excessive heat and exposure to poisonous chemicals and inhospitable terrain.
Another model is the digital camera that converts the signal to a digital output and these are even smaller than the security cameras. Often these are incorporated into the body of the computer or mobile pones and laptops. Special types of video cameras are used abroad satellites for probing space or inserted in robots creating artificial intelligence. These come in handy also for medical use.
Video cameras (filmadora) are slowly taking over the film world as video technology improves by the day. Video cameras are now able to create special effects like infinite regression - repetition of a scene.
Video cameras were first meant for broadcasting television pictures. The first ones were large, mounted on trolleys and connected by wires to recorders kept in another room. Technology meant downsizing everything to mini handy proportions.
Simultaneously costs began to go down making it more affordable to the common people. Sales shot up boosting further research in the field. Shoulder operated luggage type video cameras used to sell for US$1500. Today better features are available from a mini model of video camera (filmadora) that can rest on the palm of the hand for US$150! It is a revolution in evolution.
It consists of three parts - the lens, the imager and the recorder. The lens focuses light on the object. The imager converts this into video signal and then finally it is stored or recorded in the recorder. The camera (filmadora) section consists of the optics and the imager. The lens has an aperture to control light, zoom to define the field of vision and shutter-speed to capture motion in continuity. The electronics automatically controls and adjusts these units.
Professionals have the option of choosing from models, which have manual functions as well so that the operator has a say in the matter. The imager is the eye of the set and changes light into video signal electronically. The recorder writes the video signal on to a magnetic videotape or disc. The time and date are also recorded.
From ancient times man has been desperate and keen to capture in time what is fleeting and transitory. He has scratched on stone and papyrus building library after library of life that is as fleeting as the moving river. This urge still remains. With the video camera (filmadora) we capture eternally our personal lives and record history of protests and speeches.
