Hanwha Vision launches 90W industrial PoE security injectors

Hanwha Vision has introduced the Smart Network Industrial (SNI) range of Power over Ethernet (PoE) injectors, designed and manufactured in the UK by AMG. Engineered to simplify security camera installations in demanding environments, the new series delivers scalable PoE power from 15W up to 90W to support power-hungry pan-tilt-zoom (PTZ) cameras, heaters, and advanced surveillance edge devices across industrial and transport infrastructure.

Rugged design and versatile magnetic mounting
To eliminate the failure points typically associated with external power bricks and mechanical cooling fans, the SNI injectors feature an integrated mains power supply and a robust aluminum housing with a built-in heatsink for passive thermal dissipation. This design enables the compact units to operate reliably in extreme outdoor and industrial temperatures ranging from -40°C to +75°C. Designed for deployment inside tight roadside cabinets, camera housings, or poles, the units come standard with DIN-rail, wall, surface, and magnetic mounting accessories—the latter enabling rapid removal and replacement by technicians in the field.

Hybrid fiber networking and remote management
For geographically dispersed infrastructure such as railways and highway networks, the SNI-2HMC Hybrid models integrate an SFP port to support single- and multi-mode optical fiber connections spanning up to 120 kilometers. The hybrid variant functions dual-purpose as an unmanaged two-port Ethernet switch or a fiber media converter, streamlining network architecture. Crucially for remote sites, configurable DIP switches enable Link Fault Pass-Through (LFPT) and remote device reboot capabilities, allowing operators to hard-reset connected edge equipment from a central control room without dispatching a technician. The NDAA- and TAA-compliant range is also currently undergoing stringent certification for railway (EN 50121-4) and traffic (NEMA TS2) applications.

Additional Context: 90W PoE (IEEE 802.3bt) and Link Fault Pass-Through (LFPT)
This section details the electrical physics of high-power PoE and optical network diagnostics not included in the original press release.

Delivering 90W of direct current (DC) power over standard copper Ethernet cabling falls under the IEEE 802.3bt (Type 4 or PoE++) standard. Unlike older PoE standards that utilized only two of the four twisted copper pairs within a Cat5e/Cat6 cable, 90W PoE++ simultaneously energizes all four pairs. This drastically increases the current carrying capacity but also generates significant ohmic heating (I²R losses) within the cable bundle and the injector's internal magnetics. Operating continuously at 90W in a 75°C ambient environment without an active cooling fan requires highly specialized thermal engineering, relying on the aluminum chassis to act as a thermodynamic heat sink to prevent the internal silicon components from exceeding their maximum junction temperatures.

In hybrid copper-to-fiber topologies, diagnosing connection failures can be notoriously difficult. If a copper link drops between an IP camera and the media converter, the fiber optic side normally remains active, falsely signaling to the upstream core switch that the edge connection is healthy. Link Fault Pass-Through (LFPT) solves this "silent failure" problem at the physical layer. When enabled via the hardware DIP switch, if the injector detects a loss of link on the copper RJ45 port, it intentionally forces the optical SFP port to drop its link state. This immediately alerts the upstream managed switch to the failure, triggering automated network management alerts (such as SNMP traps) or redundant routing protocols to notify operators instantly.
