TP-Link TL-SG1005P-PD 5-Port PoE Passthrough Switch - Reliable Power

In this review the TP-Link TL-SG1005P-PD is evaluated as a compact, purpose-built PoE passthrough switch for installations that need to chain powered devices without easy AC access. The bottom line: it is for installers and small-system integrators who need a simple, rugged device that accepts a single Gigabit PoE++ input and supplies PoE+ to four downstream ports, with the biggest reason to buy being its ability to extend both power and data up to 250m in Extend Mode for short-run surveillance or remote device setups.

Key Features

• PoE Passthrough: Accepts one Gigabit PoE++ input and provides four Gigabit PoE+ outputs so multiple devices can be powered from a single PoE source.
• Flexible Power Levels: Supports different output budgets depending on input standard, delivering up to 66 W total when fed by 802.3bt Type 4 and lower budgets with older PoE standards.
• One-Click Extend Mode: Extends data and power up to 250m (820 ft) on two ports for camera or outdoor device placement when longer reach is required.
• Plug and Play: No software or configuration is required, making it quick to deploy on a desktop or mounted location.
• Auto Recovery: Built-in PoE Auto Recovery can detect and reboot unresponsive PoE devices to reduce manual maintenance visits.
• Durable Design: Sturdy metal case with fanless operation and IEEE 802.3X flow control provides quiet, reliable performance in different environments.

Who It's For

This switch is aimed at installers, small business IT teams, and DIY security camera users who need to power multiple PoE devices from a single upstream PoE++ injector or switch. It is especially useful when AC outlets are scarce and you want a compact inline device to chain cameras, access points, or other PoE gear.

Users who need managed switching features, very high aggregated throughput beyond gigabit per port, or independent AC-powered redundancy should look elsewhere; this is a passthrough, plug-and-play device designed for simplicity and PoE distribution rather than full managed switching.

Pros & Cons

Pros

• Simple passthrough design lets one PoE++ input feed four PoE+ devices without complex setup.
• Extend Mode enables power and data to reach devices up to 250m for cameras and remote units.
• PoE Auto Recovery and QoS/IGMP snooping improve uptime and video/voice performance.
• Durable metal casing and fanless design suit quiet, permanent installations.

Cons

• Must be powered by PoE only, so it requires a compatible upstream PoE++ source and no AC option is available.
• Extend Mode reduces speed to 10 Mbps on extended ports, which limits bandwidth for high-resolution streams on those connections.

Specifications

Our Verdict

The TL-SG1005P-PD is a practical, value-oriented PoE passthrough switch for scenarios where powering multiple devices from a single PoE++ feed matters more than advanced switching features. Installers and small deployments benefit from its Extend Mode, PoE Auto Recovery, and quiet metal design, but you must accept PoE-only powering and reduced speed on extended runs.

Frequently Asked Questions

Can this switch be powered from an AC adapter?
The switch is PoEPowered only and requires a compatible upstream PoE++ source; there is no AC adapter option.

How far can I run PoE with this device?
With One-Click Extend Mode enabled, Ports 1 and 2 can carry data and power up to 250 m (820 ft) but at a reduced 10 Mbps speed.

Will it reboot stuck cameras automatically?
Yes, PoE Auto Recovery can detect and reboot unresponsive PoE-powered devices when enabled to help restore connectivity without a site visit.
