Patent ID: 7958269

Claim:
A network camera configured to transmit image data in real time to a server connected thereto via a network comprising: a single imaging means; data compression means for converting the image data obtained by the single imaging means into compressed image data; network interface means for communicating with the server via the network; control means for controlling transmission processing and setting a transmission interval having a first delay interval of a first predetermined length of time and setting a second delay interval of a second predetermined length of time, such that the compressed image data obtained by the data compression means is transmitted to the server via the network interface means during the first delay interval, the transmission interval being the sum of the first delay interval followed sequentially by the second delay interval; and data store means for storing, during the first delay interval, the compressed image data to be transmitted to the server when a failure occurs in the network and the compressed image data cannot be transferred in real time to the server, wherein the control means that monitors the state of the network stores the compressed image data to be transmitted to the server in the data store means only when a failure occurs in the network, wherein, upon recovery of the network, the control means controls transmission processing such that only the compressed image data that has been stored in the data store means is transmitted to the server during the second delay interval, and wherein the second delay interval is set equal to the first delay interval when image data exists in the data store.
