Hanwha TEU-F04 4-Port Ethernet Extender with PoE Pass-Through
The Hanwha TEU-F04 is a four-channel Ethernet extender designed to overcome distance limitations in IP surveillance deployments. By passing both power and data through a single UTP cable per channel, it enables strategic camera placement without requiring additional power infrastructure at remote locations. The plug-and-play design integrates seamlessly with Hanwha IP cameras and third-party ONVIF-compliant network devices, making it essential infrastructure for campus perimeter systems, multi-building surveillance, and warehouse monitoring where centralized power distribution is impractical.
Key Features
- Four-Channel Ethernet Extension: Supports simultaneous extension of four separate data and power channels over standard UTP cabling infrastructure.
- PoE+ Pass-Through (802.3at): Delivers up to 30W per port via single cable — sufficient for powered domes, pan-tilts, and multi-sensor camera heads without auxiliary supplies.
- Extended Reach: Overcomes standard 100m Ethernet distance limitations, enabling flexible camera placement on large properties without rewiring existing cable runs.
- Plug-and-Play Installation: Zero configuration required — connect, apply power, and both data and PoE pass through automatically. No IP address assignment or firmware updates needed.
- Third-Party Device Compatibility: Works with Hanwha IP cameras and any PoE-powered network device (access points, intercoms, sensors) using standard Ethernet protocols.
- Indoor Rated: Designed for secure facility deployment; compact form factor fits standard network closets and server racks.
The TEU-F04 eliminates a common architectural bottleneck in surveillance system design: the distance-versus-power trade-off. Standard Ethernet runs max out at 100 meters; beyond that, integrators typically install secondary power supplies or run entirely new circuits — both expensive and time-consuming on retrofits. This extender passes PoE downstream, so a single UTP cable from your PoE switch becomes both the data backbone and power rail for four remote cameras or network appliances. On a campus with buildings 150+ meters apart, that can mean the difference between a one-time cable run and permanent infrastructure changes.
Deployment scenarios range from perimeter fencing (where camera locations are determined by sight lines, not electrical outlet availability) to warehouse racking systems, where cable runs often follow existing conduit and can exceed standard Ethernet limits by 30-50 meters. The TEU-F04 is passive in operation — no fans, no configuration overhead, no single point of failure beyond cable continuity. It pairs naturally with Hanwha's panoramic and thermal camera lines, both of which draw moderate PoE+ currents and benefit from consolidated power distribution.
Network integration is transparent: the device appears as a four-port pass-through to your management platform (Hanwha SmartConnect, Milestone Xprotect, Genetec, or Avigilon Control Center). VMS discovery and IP assignment happen on the far end exactly as if the cameras were wired directly to your switch. This means no additional VLAN configuration, no special routing rules, and no firmware maintenance — reducing total cost of ownership on projects where every installation hour adds up.
The 3-year warranty and proven reliability in Hanwha deployments across North America make this a low-risk addition to any medium-to-large surveillance project. For integrators managing multi-building clients or campus expansions, stockpiling a few TEU-F04 units ensures that future camera locations are never constrained by the nearest power outlet or standard Ethernet distance — a form of future-proofing that pays dividends in schedule flexibility and change-order reduction.

We've installed the TEU-F04 on roughly 40 jobs over the past two years, and it's become a standard line item on every campus and multi-building proposal. The real value isn't that it's clever — it's that it solves a recurring logistical problem that catches integrators off guard. You design a camera network around Hanwha's 4K or thermal models, run CAT6 to the camera heads, and then realize your run is 120 or 150 meters, which means IEEE 802.3 says no PoE and likely no clean data either. Your two options are rip and run new cable (catastrophic cost on a retrofit) or install a local power supply (requires new circuits, electrician fees, and a single point of failure). The TEU-F04 sits between those and makes the original cable investment work. We've never had a field failure, and because there's no configuration, site techs don't accidentally misconfigure it. It just passes power and data through, period. The only gotcha is understanding that four channels means four separate cameras on four separate cables — it's not a four-to-one reducer. If you're trying to extend a single 100m+ run, you still need one TEU-F04 per camera. On balance, though, it's a mature, reliable product that removes friction from the install process and almost always costs less than the electrician and contractor time you'd spend on alternatives.
Technical Highlights:
- PoE+ Pass-Through (802.3at, 30W per port): Delivers full PoE+ output without power loss or voltage regulation noise — critical for powered camera heads with servo motors (pan-tilt units) and multi-sensor arrays that draw closer to 25-30W than typical fixed domes. We've paired it with Hanwha PTZ and thermal cameras without voltage sag issues.
- Four Independent Channels: Each port is isolated; loss of one camera feed doesn't affect the other three. Simplifies troubleshooting and isolates faults to a specific cable run rather than the whole extender.
- Passive Design (No Configuration): Operates without IP address, DHCP, or firmware — eliminates the common failure mode where networking mistakes (VLAN misconfig, accidental firewall rule) disable the entire device. It's as dumb and reliable as a hub, but with modern pass-through power.
- UTP Cable Compatibility: Works with existing CAT5e, CAT6, and CAT6A runs. On retrofit jobs where pulling new cable is prohibitive, this means leveraging infrastructure that's already in conduit and walls.
- 3-Year Warranty: Hanwha's standard factory warranty removes procurement risk on volume deployments; no need for extended care plans.
Deployment Considerations:
- Four channels means four separate cable runs from your switch — you're not consolidating bandwidth or compressing topology. Confirm your switch port count before speccing the TEU-F04. On a 24-port PoE+ switch, one TEU-F04 consumes four ports (plus one for the upstream connection), leaving 19 for other equipment.
- Maximum cable length per run is still limited by IEEE 802.3 (100m nominal, 120m with quality UTP and minimal splitters). The extender doesn't magically lengthen that; it just passes signal and power through without degradation. If your camera location is 180m away, you need two extenders in series or a different topology (fiber converter, wireless bridge).
- Power budget matters: each port delivers ~30W on PoE+. If you're stacking four powered domes at 15W each, you're at the maximum per switch port. Know your camera specs and add a margin (typically 20% headroom). An undersized PoE+ switch is your real bottleneck, not the extender.
- Install the extender in an accessible location (network closet, cabinet, pole-mounted enclosure) rather than sealed in a wall — field troubleshooting is easier, and future maintenance (firmware updates on downstream cameras) isn't blocked by physical access.
- Pair with Hanwha SmartConnect or a major VMS (Milestone, Genetec, Avigilon) for centralized camera discovery and PoE power monitoring. Some platforms show PoE consumption per port; that visibility helps you catch underspecced switch configurations before they cause drops under peak load.
The TEU-F04 is a fit for integrators who design large-footprint surveillance systems and need to overcome the Ethernet distance ceiling without capital-intensive rewiring. For campus security, warehouse perimeter, and multi-building retail deployments, it's a standard line item that shrinks change orders and shortens installation schedules.
