Claim Text:
1. A wireless surveillance camera system comprising: (1) a wireless base station that receives a wireless signal transmitted from at least one wireless surveillance camera device, the wireless base station comprising: a transmission unit that wirelessly transmits a generated polling packet to each wireless surveillance camera device in a polling system; and a scheduling controller that controls transmission timing of the polling packet; and (2) at least one wireless surveillance camera device comprising a camera device and a wireless device, the wireless surveillance camera device comprising: a signal processing unit that applies signal processing to video and/or voice data from the camera device; an identification information categorization unit that adds identification information to the video data and/or voice data after the signal processing; a configuration unit that acquires configuration information data related to video parameters and/or wireless parameters inside of the device; a protocol processing unit that applies protocol processing to the video and/or voice data and the configuration information data to generate a communication frame; at least one first transmission queue associated with the polling system; at least one second transmission queue associated with a carrier sense access system; a selection unit that refers to the identification information added to the communication frame to forward the video and/or voice data to the first transmission queue associated with the polling system and to forward the configuration information data to the second transmission queue associated with the carrier access system; an interface controller that forwards the communication frames stored in the first and second transmission queues to the wireless device; and the wireless device comprising: a first access controller that acquires a transmission right in the polling system; a second access controller that acquires a transmission right in the carrier sense system; and a transmission unit that wirelessly transmits the communication frames received from the first and second transmission queues at timings that the corresponding transmission rights are obtained.
