An Internet Protocol (IP) camera, or IP cam, is a kind of computer-based video camera which receives control information through an IP network and transmits image data to an IP-enabled receiver. As with traditional closed-circuit video cameras, they are widely used for personal surveillance but unlike traditional analog closed-circuit video cameras, they need no local recording unit, just a broadband internet connection. The IP camera is connected to the internet using a USB or parallel cable and then to the receiver through the same cable. The software which controls the IP camera can be downloaded from the manufacturer’s website to the receiver. The software allows the user to view the images on the screen of the IP cam or watch the captured images on another computer that is connected to the internet using a browser.
There are two kinds of IP cameras: wireless and wired
A wireless IP camera uses radio frequencies to transmit the images. Wired IP cameras use an IP network connection as their source of power, though they do not use radio waves. These IP cameras are less expensive than those using radio frequency signals.
Both kinds of IP cameras have several advantages over each other. An IP camera uses a small form of technology called the Video Dome System which transmits the video feed through a large number of individual domes. These domes are referred to as ‘lenses’ because they have a great field of view and because they limit the resolution of the video feed. This means that the IP camera may need to ‘see’ something that a regular eye would not, such as a fence or a wall. The Video Dome System reduces this distortion and also reduces the amount of light which is reflected off any part of the lens or dome. In addition, if a person standing in front of the IP camera can see into the lens, then the entire scene will be clearer and more zoomed in than it would be if the IP camera used a conventional lens.
The main advantages of using IP camera
The major advantage of IP cameras over other security features is that they are almost impossible to jam. It has long been known for malicious hackers to infiltrate office networks. These hackers can use a variety of tools to breach computer systems and then relay their viruses and other harmful programs. Traditional IP cameras are not secured against cameras being jammed. In fact, a wireless camera system is much more secure than one that features wires.
Wireless IP cameras can also be set up anywhere there is an Internet connection. Many companies have discovered that it is cheaper and easier to set up wireless IP cameras at the offices. Security personnel at the locations can then monitor the IP cameras and the Internet activities going on. This makes IP surveillance a valuable tool for many businesses.
Another advantage of IP cams is that they can work well in a small space. A typical desktop IP camera will need a large space in order to work properly. However, an IP camera that is placed in a bag or backpack will easily fit into a standard sized bag and is then compact enough that a worker can carry it around without a problem. This makes it possible to use IP cams even outside the office which is often necessary for monitoring employees from afar. There are some reliable brands like amcrest.com that can be considered for buying IP cameras.
