This article is the first of a collection describing how to switch a webcam, also recognized as an IP camera, or an Internet camera into a versatile surveillance and security system. Add lights, motion detectors, outdoor enclosures, wireless adapters and even movable Internet cards to an Internet (IP) camera and you get a powerful, yet economical electronic watchman. These can be great for keeping an eye on holiday houses and RV's, remote work sites, outdoor businesses, such as quarries or power stations, stored equipment, or even as remote outdoor webcams. A webcam is a video camera which sends its images in real time to a computer or computer network, often via USB, ethernet or Wi-Fi. Their most common use is the formation of video links, letting computers to act as videophones or videoconference stations. This common utilization as a camera for the web gives the webcam its name. Other standard uses to add are security surveillance and computer vision. Webcams typically have a lens, an image sensor, and some support electronics. A lot of lenses can be used, 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 don't have provision for adjustment, are also available. As a camera system's depth of field is better for small imager formats and is good for lenses with a large f-number (small aperture), the systems used in webcams have adequately large depth of field that the utilization of a fixed focus lens doesn't impact image sharpness much. Image sensors can be CMOS or CCD, the first one being prevalent for inexpensive cameras, but CCD cameras don't actually outperform CMOS-based cameras in the economical price range. Numerous consumer webcams are capable of providing VGA-resolution video at a frame rate of 30 frames per sec. A lot of newer devices can create videos in megapixel resolutions.

A Passive InfraRed sensor (PIR sensor) is an electronic device that quantifies infrared (IR) light radiating from objects in its field of sight. PIR sensors are mostly used in the building of PIR-based motion detectors. Plain motion is determined when an infrared source with one temperature, such as a human, goes before an infrared source with another temperature, such as a wall. All things above absolute zero give out energy and are in reference to what is recognized as black body radiation. It is usually infrared radiation that's invisible to the naked eye but can be noticed by electronic devices designed for such an intent. The term passive in this instance signifies that the PIR gadget does not emit an infrared beam but just passively accepts incoming infrared radiation. "Infra" meaning below our ability to detect it visually, and "Red" because this color is the smallest energy degree that our eyes can see before it becomes obscure. Thus, infrared stands for below the energy degree of the color red, and applies to numerous sources of concealed energy. The motion sensor can be linked to the webcam in such a mode as to perform a lot of functions. If an individual or a car approaches the monitored area, the movement can have a light to illuminate the area, preventing malicious mischief or theft. Recording can automatically start on a distant computer on the Internet, so that any activity will be caught for good. An additional option could make an alert to be sent to you or to a third-party supervising service. You could then link your PC directly to the camera and look at the action that activated the alarm, using your own computer. You can even listen, if the camera has a microphone. You can even link from anywhere in the world over the Internet. Going on vacation or business trip? Just bring your laptop or borrow somebody's computer and plug in to your cameras inside a few seconds.
