This article is the first in a series detailing how to transform a webcam, also known as an IP camera, or an Internet camera into a thorough surveillance and protection measure. Add lights, motion detectors, outdoor enclosures, wireless adaptors and even portable Internet cards to an Internet (IP) camera and you produce an ingenious, yet economical electronic security guard. These can be perfect for keeping an eye on vacation homes and RV's, faraway job sites, faraway businesses, such as quarries or power stations, stored equipment, or even as remote outdoor webcams.
A webcam is a video recording camera which sends its images in up to date time to a computer or computer network, frequently via USB, ethernet or Wi-Fi. Their most popular use is the formation of video links, letting computers to perform as videophones or videoconference stations. This popular function as a camera for the web presents the webcam its name. Other popular uses are for security monitoring and computer vision. Webcams commonly have a lens, an image sensor, and some support electronics. Different lenses are readily available, the most popular in consumer-grade webcams is a plastic lens that can be screwed in and out to set the camera's focus. Fixed focus lenses, which have no features for adjustment, are also available. As a camera system's depth of field is greater for small imager formats and is better for lenses with a large f-number (small aperture), the systems used in webcams have sufficiently large depth of field that the application of a fixed focus lens does not impair image sharpness much. Image detectors can be CMOS or CCD, the first being dominant for cheap cameras, but CCD cameras don't necessarily outperform CMOS-based cameras in the economical price range. A lot of consumer webcams have the capability of providing VGA-resolution video at a frame rate of 30 frames per second. Most newer devices can produce videos in megapixel resolutions.

Add an infrared motion detector. A Passive InfraRed sensor (PIR sensor) is an electronic gadget that counts infrared (IR) light shining from things in its field of view. PIR sensors are commonly used in the construction of PIR-based motion detectors. Plain motion is detected when an infrared source with one temperature, such as a human, moves in front of an infrared source with another temperature, such as a wall.
All things above absolute zero give off energy and are in reference to what is acknowledged as black body radiation. It's commonly infrared radiation that's concealed to the human eye but can be perceived by electronic devices constructed for such an intent. The term passive in this case signifies that the PIR device doesn't give out an infrared beam but simply passively takes incoming infrared radiation. "Infra" meaning below our ability to ascertain it visually, and "Red" because this color stands for the smallest energy degree that our eyes can notice before it turns concealed. Thus, infrared means below the energy degree of the color red, and applies to many sources of hidden energy.
The motion detector can be attached to the webcam in such a mode as to act many functions. If an individual or a vehicle comes near the fortified area, the movement can make a light to illuminate the area, deterring malicious mischief or stealing. Recording can automatically set out on a faraway computer on the Internet, so that any action will be captured permanently. A supplemental bonus could cause an alert to be directed to you or to a third-party monitoring service. You could then link your PC directly to the camera and view the action that triggered the alarm, using your personal computer. You can even listen, if the camera has a microphone. You can even link from anywhere in the world thru the Internet. Going on vacation or business trip? Just take your laptop or borrow somebody's computer and connect to your cameras inside a few seconds.
