The document describes the Longspan technology for delivering power and bandwidth over long distances using standard Cat 5e or Cat 6 cables, allowing IP camera installations to exceed traditional Ethernet limits. It supports various power-over-Ethernet (PoE) configurations up to 600 meters while maintaining full bandwidth, and includes features like self-configuration and diagnostic displays for easy installation. It also enables the upgrade of legacy cabling to support modern IP cameras without needing to replace existing infrastructure.
