A network sensor system and protocol is provided. The network sensor system includes a sensor node that has a sensor for collecting high-resolution data, and a radio for transmitting that data to a central hub. The sensor node communicates to the hub with a wireless data link, and operators solely from a battery. Accordingly, the sensor node is autonomous, and has no wire connections, so may be discreetly and simply installed. The sensor node is normally operated in a power-saving sleep mode, and is minimally activated only for required periods of time. The sensor node may be activated responsive to a low power timer, or from another locally generated interrupt. The sensor node also implements power-saving transfer protocols to further reduce power needs. Many sensor nodes may be associated with a single central hub, and larger networked sensor systems may be arranged.
