IP stands for internet protocol. IP cameras use network cable and provide a good solution for projects that require a large number of cameras. IP cameras have higher resolutions than standard analog cameras and provide sharp images at higher resolutions. IP cameras use Ethernet cable to transmit power, video and data. Some downsides of IP cameras is that they require a complex network infrastructure and are very pricey compared to TVI and AHD cameras. IP cameras are increasingly being used in surveillance circuit electronics, where they are replacing traditional CCTV cameras. They can be either wired or wireless, cutting the cost and maintenance required for regular cameras used in a CCTV surveillance circuit. IP cameras tend to capture better quality images, which is especially helpful in the case of moving targets, as frame rates can be adjusted according to the bandwidth provided. They support two-way communication and hence can send customized alert signals in case of suspicious activity or other predefined occurrences. Hundreds of gigabytes of video and image data can be stored in video servers, which can be retrieved at any time.
