The communication channel dynamically adjusts and utilizes high-performance error correction coding technology for enhanced performance. Plug and play functionality, ensuring transparent transmission without needing adjustments or changes to upgrade the software or install any drivers. Supports PoE power supply (IEEE 802.3af/at) and Power over cable (PoC) technology. Even more: The master device can be powered by the 48VDC-56VDC local power source (which comes for free set with your order), or powered up by a PoE switch locally. Slave (remote devices) does not require local power, it is powered up remotely over the same copper or BNC cable;. Ethernet Signal & Power for up to 4 remote devices, such as PoE cameras, PoE-powered IP phones, and other devices, is delivered over the same copper pair. Ethernet Signal & PoE power transmission depends on many factors such as cable quality, type, and diameter, with BNC to 2PIN wire adapter, use it also with RG59 or other coax cables. Extend up to 4 ports of Ethernet & PoE Power over Same Cable Pair - max transmission theoretical distance can reach 1000m (0.5mi) signal distance and 500m (1640ft) for PoE signal.
