An imaging apparatus connected to another imaging apparatus and a reception apparatus via a network. A reception section receives a transmission request requesting transmission of first video data photographed by the imaging apparatus to the reception apparatus, from the reception apparatus. A determination section determines, based on processing load on the imaging apparatus, a distribution capacity of the imaging apparatus, or conditions of the network, whether or not the imaging apparatus is to execute transmission processing for transmitting the first video data to the reception apparatus. An acquisition section acquires, in a case where the determination section has determined that the imaging apparatus is not to execute the transmission processing, a transmission destination to which a request for acquiring second video data photographed by said another imaging apparatus is to be transmitted.
