Assessing POE's near-term uses

摘要

The next probable stage of power-over-ethernet development will be in industrial automation and building control, based on interviews with officials at Cisco Systems Inc., Texas Instruments Inc. and PowerDsine Ltd. Temperature, smoke, heat and other environmental sensors will probably be at the top of the list of near-term future developments and will start appearing sometime in the next several years when integrated chips to control power flow become more widely available. POE will make network cameras more prevalent, and cutting the AC cord will also make building security monitors such as badge swipe pads easier to implement.
