This writeup is the second in a series depicting how to convert a simple webcam, also known as an IP camera, into a total security and surveillance system. Add lightings, movement detectors, outside enclosures, wireless adapters and other electronic devices to an Internet (IP) camera – and you now have a prestigious, yet cost-effective electronic security guard. Surveillance systems such as these can be ideal for watching over vacation homes and RV’s, distant job locales, faraway businesses, or anything which needs monitoring. First step to achieve this was to connect a PIR sensor to the camera to trigger it to send alerts and to get images or videos of the events which triggered the detector. Next is to attach a floodlight to dissuade would-be wrongdoing or thievery.

A web camera is a video camera which feeds its images in real time to a computer or computer network, via utilizing different transmission devices. Their favorite use is the establishment of video links, granting local or faraway PC’s to act as Digital Video Recorder (DVR), or particularly, Network Video Recorder (NVR) stations. This common use as a camera for the web gives the webcam its nbickname “webcam”. Webcams usually have a lens, photo sensor, and several support devices. Diverse lenses are available, the most common in consumer-grade Internet cameras being a plastic lens that can be jockeyed in and out to set the camera’s default focus. Fixed focus lenses, which have no room for alteration, are also obtainable. As a camera’s astuteness of sphere is broader for little image formats and is grander for lenses having a large f-number (small aperture), the systems used in webcams have sufficiently large deepness of field that the employment of a fixed focus lens does not bear upon image sharpness much. Image detectors can be CCD or CMOS, with CMOS being dominant for affordable cameras, but CCD cameras do not really surpass CMOS-supported cameras in the low-cost price range. Most consumer-type webcams are capable of providing VGA-resolution video at a frame rate of 30 frames per second. Many newer devices can produce video in big pixel resolutions.

Support devices installed within read the photo from the detecting device and convey it to a local host computer via Ethernet cable or other connectivity. If a server is not available, the cameras can be connected to the Internet directly, using the common wireless Internet cards, such as 3G and 4G cards from diverse suppliers. Some more high-end cameras include built-in processors that add multiple features, such as motion sensing transmission, email transmission, scheduled sending of stationary pictures and videos. There are those which can likewise include pictures within emails. Virtually all webcams have built-in microphones.

Connect a powerful floodlight to the web camera. The floodlight can be activated by the PIR sensor. Alternatively, other cameras are already capable of turning on the lights remotely using the remote-viewing application, making them useful for different monitoring functions. Some cameras have the support electronics to turn on lighting to not only illuminate the area under surveillance, but also serve as a thievery determent. Most trespassers like the shadows and will generally take flight when strong lights are turned on in reaction to their movements. One such webcam is available from Offsite Commander Systems.

By awareness the function of megapixel in a digital camera, you will be able to buy the finest option at the cheapest rate. Even beginners will be able to opt a better camera.

Higher the megapixel count, better is photo-quality?

This is one of the most misunderstood impression about rating of digital camera and their photo excellence. Consider a mosaic of tiles, each megapixel is like a tile and a mosaic of these tiles make a picture clearer. That is all right, but it doesn’t mean that picture taken by a 10 or 12 or 50 megapixel camera will be more sharp than a 3 megapixel camera, because for most practical purposes, 3 megapixel quality is good enough. At the most you may require 6 – 8 megapixel for photo-quality as appears in magazines. Anything ahead of that isn’t of much use to a non-professional photographer.
One megapixel is like one tile. When a picture is taken, the CCD or CMOS sensor in the camera receives an array of such tiles to create an image. It then converts it to electrical signals which are processed to deliver a picture. An array of 2048*1536 generates a pixel count of 31,45,728 pixel which is amount to to 3.1 megapixel.

What affects the quality of pictures then?

The quality of the lens, the algorithms used to make the photo from raw data composed by the sensor and the focusing mechanism are some of the other factors that affect the final result.
It should also be considered, how large is the sensor in the camera. Consumer digital cameras have tiny image sensors. They are measured in microns. A micron is a millionth of a meter. Most sensors in consumer cameras are less than 10 microns. It is kept so so as to decrease the size of the camera so you can carry it in your pocket.

DSLR cameras have larger sensors. The main disadvantages of a smaller sensor is that it generate images with more noise than a large sensor. If you have to focus on a small area, it is difficult to do with a small sensor. Further, any shaking in handling the camera is blown up in a small sensor.

That means in right hand, with a appropriate sized sensor, a 6 MP camera is also good enough. In few scenarios a larger megapixel count may be useful, but for general purposes, it is not required.

In what scenario is a higher megapixel beneficial?

If you have to take the photograph of an airplane or a bird flying at a distance and you starting zooming with a digital camera, use digital zoom to reach it, the picture becomes granular. This is a typical defect of the digital zoom. In such a case, if you have a higher megapixel count, you won’t need the digital zoom.

Buy wisely choosing the appropriate megapixel rating you will be able to get a cheapest yet a better digital camera.
