This article is the third in a series keying out how to transform a webcam, also named as an IP camera, or an Internet camera into a thorough surveillance and protection measure. Add lights, motion sensors, outdoor enclosures, wireless adaptors and even portable Internet cards to an Internet (IP) camera and you get an ingenious, yet cost-efficient electronic security guard. These can be perfect for monitoring vacation homes and RV's, distant work sites, outdoor businesses, such as quarries or power stations, stored equipment, or even as remote outdoor webcams. was to add a Passive InfraRed (PIR) detector to the camera to activate it to beam alerts and to upload pictures or videos of the activities that activated the sensor. The 2nd step is to add a floodlight to dissuade would-be mischievousness or thievery. Step 3 involves adding a wireless module so that the cameras can be installed without the need for data or video cabling.

A webcam is a video camera which transmits 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 establishment of video links, permitting computers to act as videophones or videoconference posts. This popular utilization as a camera for the web hands the webcam its name. Other popular uses include security monitoring and computer vision. Webcams typically include a lens, an image sensor, and some support electronics. A lot of lenses are available, the most common in consumer-grade webcams being a plastic lens that can be placed and removed to determine the camera's focus. Fixed focus lenses, which do not have features for adjustment, are also available. As a camera system's depth of field is great for small imager formats and is better for lenses with a large f-number (small aperture), the systems used in webcams have adequately large depth of field that the use of a fixed focus lens doesn't impact image sharpness much. Image sensors can be CMOS or CCD, the first being prevalent for affordable cameras, but CCD cameras do not really 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 make videos in -megapixel resolutions.

Support electronics read the image from the sensor and beam it to a local server computer via Ethernet cable or wireless bridge, letting a wireless connection to the server computer. If a local server computer is not ready, the cameras can be linked to the Internet directly, using the standard wireless Internet cards, such as 3G and 4G cards from suppliers such as Verizon and Sprint. Some more compelling cameras have embedded processors that add several features, such as movement detection transmission, email transmitting, scheduled transmitting of still photos and videos. Some can even add still photographs and video images within email alerts. Most webcams own internal microphones.
Add wireless module (WiFi) to the camera. A wireless network normally is not totally wireless because some part of equipment will most likely be linked to the internet source by wire (cat 5 or cat 6). That link depends on your equipment and the service type. Some internet modems have wireless router ability "built-in" but in that case the modem will still be connected to your wall or where ever the internet gets into the room. You will also be connected to the power socket. What you obtain depends on what type of service you get, who supplies it, and what equipment is provided.
The effective distance between the cameras and the wireless Internet access point changes because of environment and capability of the equipment. Presently the range can be up to three hundred ft for some gadgets without "extra help" but in general many basic systems are rated as up to 150 ft. Closer commonly implies better signal intensity and video quality, but not constantly. Other factors like metal I-beams, cordless phones, wireless remote controllers and other electronic devices, among other things, can affect the quality of a signal. There are wireless extenders/relays accessible that can extend the range of a wireless signal. Some are in the figure of a high-powered antenna, some are similar to wireless adapters and are plugged into a power outlet along the path to a computer distantly located. So the gadget relays the wireless signal to the different computers. Wireless connection can be modified to computer peripherals, such as an IP, or Internet camera. This configuration permits the cameras to be set up hundreds of feet away from the Internet access point. One such camera is supplied by Offsite Commander Systems.
