Disclosed is a communication system including a first set of wireless cameras, a first hub and a first relay device receiving first video data. Also included is a second set of wireless cameras, a second hub and a second relay device which receives (i) the first video data and (ii) a second video data. Included is a third set of wireless cameras, a third hub and a third relay device receiving (i) the first and second video data and (ii) a third video data. A monitoring device monitors the first, second and third relay devices. A video management system receives the first, second and third video data from the third relay device. If the second relay device is unable to transmit the video data at a minimum quality level, the monitoring device sends a signal directing the first relay device to send first video data via the third relay device.
