Abstract
A method of improving video performance in video surveillance system having a wireless encoder connected to a video surveillance network by a wireless access point device comprises the steps of allocating channel bandwidth to the wireless encoder from the wireless access point device, transmitting packets of video data from the wireless encoder to the wireless access point device, transmitting signals from the wireless access point device to the wireless encoder, monitoring the strength of the signals received by the wireless access point device, the strength of the signals received by the wireless encoder, and the number of lost packets of video data transmitted from the wireless encoder to the wireless access point device, sending a request from the wireless encoder to the wireless access point device to change the bit transmission rate of the wireless encoder if the strength of the signals received by the wireless access point device is less than a first threshold, if the strength of the signals received by the wireless encoder is less than a second threshold, or if the number of lost packets of video data is greater than a third threshold, and changing the bit transfer rate of …
