1. A method, comprising:
by a network node operationally coupled over a network to a set of optical sensor devices positioned throughout a space, with each optical sensor device having an optical sensor with a viewing angle associated with a certain region of the space and enabled to send at least one of a set of image streams associated with that certain region to the network node over the network, with each image stream having a certain resolution or frame rate, the network node being operable to select the at least one of the set of image streams of each optical sensor device,
receiving, from a first optical sensor device of the set of optical sensor devices, a first image stream of the set of image streams of the first optical sensor device that is selected based on both a confidence level that represents a level of certainty that a detected object is correctly detected from a second image stream of the set of image streams received from the first optical sensor and a current network bandwidth utilization of the network so that the confidence level of the detected object detected from the first image stream is increased or decreased from the confidence level of the detected object detected from the second image stream and the current network bandwidth utilization of the network is maintained below a certain network bandwidth utilization threshold, with the first and second image streams having a different resolution or frame rate and the first optical sensor having a viewing angle towards the detected object.
