IP camera is a type of digital video camera that receives control data and sends image data via an IP network.They are commonly used for surveillance but unlike analog cameras, they require no local recording device, only a local area network.
Some IP cameras require support of a central network video recorder (NVR) to handle the recording, video and alarm management.Others are able to operate in a decentralized manner with no NVR needed, as the camera is able to record directly to any local or remote storage media.
IP cameras offer resolutions that can range from 1.3MP to 5MP of compressed encoded transmissions.
They also work over twisted-pair, coax cable and with wireless connections and can send digital video 100 metres over twisted-pair Ethernet cable and unlimitted distances over IP networks.
License Plate Recognition
License Plate Recognition can be used to store the images captured by the camera as well as the text from the license plate, with some configurable to store a photograph of the driver.
Systems commonly use infared lighting to allow the camera to take the picture at any time of day or night.
An analog camera is a traditional camera used in cctv systems.It sends video over cable to VCRs or DVRs.They are limitted to resolutions that range from 420 to 700, which at the high end can produce sharp images.They operate over coax cable and can send video over twisted-pair cable up to 1.5 kilometres and up to 300 metres away over coax. Analog cameras require more cabling than IP cameras.
