Power over Ethernet (PoE) is now available on all PicSight-GigE cameras and PicSight-Smart models, including versions with lens control. PoE using Gigabit Ethernet applies the technique of phantom power over two of the pairs, allowing the transfer of 48-VDC power mixed with Ethernet signals.
Power and data can reliably be separated and provide no bandwidth loss. You can install a camera with a single standard Cat5e cable. PoE is useful for applications handling multiple cameras or where external power is not a viable or convenient option.
Power over Gigabit Ethernet is compatible with GigE Vision because it does not affect the content of data being transmitted.
Gigabit Ethernet is now an established camera interfacing technology in machine vision. Its cost, deployment ease, long cable capability as well as support for multiple devices made it a superior choice in most applications over other competing technologies.
Power-Over-Ethernet (PoE) is not a new phenomenon. Based on slower version of the Ethernet protocol, it used the spare wire pair to provide power. Gigabit Ethernet, on the other hand, already makes use of all the wire pairs of the standard cable, therefore providing power is more challenging. The IEEE 802.3af Standard determines how power is delivered on Gigabit Ethernet. It applies the technique of phantom power over two of the pairs. This allows the transfer of 48VDC power mixed with Ethernet signals.
Practically, power needs to be injected on the network. It is usually done with standard network powered-switches. The installation is even simpler than regular equipment. Furthermore, Power-Over Gigabit Ethernet is compatible with GigE Vision as it doesn't affect the content of what is transmitted.
