IP cameras are widely seen as the future of video surveillance. Unlike traditional analog security cameras that require a dedicated cable to connect the camera to video management systems, IP cameras can connect to standard computer networks, allowing dozens of IP cameras to be transmitted over the same cable to any location with Internet access and sufficient bandwidth. As of 2009, though widely promoted, only 1 out of every 5 buyers choose IP cameras. In the next 3 to 7 years, IP cameras are projected to be the dominant camera type selected. However, there are still key challenges for IP cameras and you must understand IP camera advantages and disadvantages before purchasing. If you do choose IP cameras and currently have analog cameras, you will need to determine how to migrate from analog to IP cameras (an often complex and costly process especially because there are no standards for IP cameras).
