An Ethernet cable is the physical link between your Reolink PoE camera and your network — it carries both data and power over a single cable. This article introduces the Ethernet cable requirements for Reolink devices, including supported cable types, wiring standards, maximum cable lengths, practical connections, and the Ethernet cables included in Reolink products.
Applies to: Reolink TrackMix Wired LTE, Trackmix Series G765, Reolink Wi-Fi camera with an Ethernet (LAN) Port, and all Reolink PoE cameras.
Introduction to Ethernet Cables and Wiring Standards
An Ethernet cable is used to connect a device to a local network for data communication. It enables devices such as cameras, NVRs, routers, and computers to communicate with each other and access the Internet.
For Reolink cameras, an Ethernet cable can be used for device setup, network communication, or Power over Ethernet (PoE), depending on the camera model.
Reolink cameras support Ethernet cables that meet the following requirements:
- T568B wiring standard
- CAT5, CAT5e, CAT6, or CAT7 Ethernet cables
- Standard RJ45 (8 PIN) connectors
Using a cable that meets these requirements helps ensure stable network communication and reliable PoE power delivery. You can purchase an Ethernet cable from the Reolink official website if you need.
For more details about Ethernet cable, refer to Introduction to Ethernet Cable.
Recommended Cable Length
The effective maximum cable length between the camera and the network device (e.g., NVR or PoE switch) depends on the cable category and what the cable is connected to:
| Cable Type | Recommended Maximum Length |
| Cat5 | Up to 80 m (262 ft) |
| Cat5e and above | Up to 100 m (328 ft) |
To ensure stable network communication, use a Cat 5e or higher Ethernet cable and keep the cable as short as practical. Lower-category cables may result in a shorter maximum transmission distance.
Ethernet Cable Included with Reolink Products
The Ethernet cables included in your Reolink package depend on what you purchased:
| Product Type | Cables Included | Purpose |
| Single Camera | 1 × 1 m CAT5 Ethernet cable | For initial camera testing or permanent installation |
| Standard System Kit | 1 × 1 m CAT5 + 1 × 18 m CAT5 per camera | 1 m for testing, 18 m for permanent installation |
| Bundle Kit | May vary — check "What's in the Box" on Reolink official website | Some bundle kits may not include the 18 m cable |
Typical Connection Scenarios
Depending on your device's layout, there are several common ways to connect your Reolink PoE cameras. Choose the scenario that best matches your setup:
▶ Reolink PoE Camera ── Ethernet Cable──> PoE NVR (RJ45 Port)
▶ Power outlet< ── Power Adapter──Reolink PoE Camera ── Ethernet Cable──> Router (No NVR)
▶ Reolink PoE Camera ── Ethernet Cable──> PoE Switch/Injector ── Ethernet Cable──> NVR ── Ethernet Cable ──> Router
If you have a Wi-Fi camera with a LAN port and want to connect it via an Ethernet cable, make sure the power adapter remains connected. And follow the same connection method described above.
To know more about the connection among these devices, refer to How to Use Ethernet Cable.
Choosing the appropriate Ethernet cable is an important part of ensuring reliable network connectivity and PoE performance. Before installation, verify that the cable type, wiring standard, and cable length meet the recommended requirements for your Reolink device.
