Antaira Adds Two- and Four-Port PoE Surge Protectors for Industrial Networks

Antaira introduces a multi-port option for protected PoE links

Antaira Technologies has announced the LSP Series, a pair of industrial PoE surge protectors intended to sit inline between network equipment and PoE-powered endpoints. The release was published on August 26, 2026, and Antaira’s product catalog now lists both the two-port LSP-0200X-bt-100-T and four-port LSP-0400X-bt-100-T as available products.

The launch is notable less for introducing surge protection as a category than for placing multiple protected PoE channels in one industrially packaged device. That can matter where several field devices terminate near one cabinet or network boundary, such as a group of perimeter cameras, outdoor wireless access points, roadside devices or building-entry systems.

Two and four protected channels

The LSP-0200X-bt-100-T provides two PoE input connections and two corresponding PoE output connections. The LSP-0400X-bt-100-T scales that arrangement to four inputs and four outputs. Antaira describes both as inline protectors rather than Ethernet switches: they protect and pass traffic and PoE through their respective channels, but do not add switching or management functions.

For each channel, Antaira specifies RJ45 interfaces supporting 10/100 Mbps, 1G, 2.5G, 5G and 10G Ethernet. The published maximum PoE pass-through rating is 100W PoE++ per channel. That specification is relevant for designs moving beyond conventional camera loads to higher-power devices, provided that the upstream power-sourcing equipment, cabling and endpoint all support the intended PoE class and power budget.

Industrial enclosure and environmental specifications

Both LSP models are specified with an IP30-rated enclosure, DIN-rail mounting or wall mounting, and a -40°C to 75°C operating-temperature range. Those characteristics can simplify placement within an industrial control cabinet, telecom enclosure or other protected equipment space that requires a compact, mechanically secure installation.

An IP30 rating should not be confused with an outdoor weatherproof rating. For exterior camera, wireless bridge or gate-access deployments, the surge protector and its terminations may still require a suitably rated enclosure and cable-entry approach. Procurement teams should review the complete installation environment, including condensation, contamination, enclosure heat rise and access for service.

What the 10 kA claim means for project review

Antaira lists surge protection up to 10 kA for both LSP models and states that the devices are designed to protect against lightning-related electrical events, surges and transient voltage spikes. This provides a starting point for comparing products, but a single surge-current number does not by itself establish suitability for a specific site.

Before specifying an inline protector, engineers and integrators should request and review the full technical documentation for the relevant model. Important project checks include the surge test waveform behind the stated rating, clamping or protection voltage, conductor and grounding requirements, supported PoE modes, insertion loss at the required data rate, and any applicable safety or EMC approvals. The protector’s earth connection and the site bonding design are central to the intended diversion path for surge energy.

Where the LSP Series could fit

A multi-port inline device may be useful when a single field cabinet supports several PoE links exposed to long cable runs or transitions between buildings and outdoor areas. Security and facilities teams could evaluate it for clusters of IP cameras, intercoms, access-control panels and IP speakers. Industrial and transportation projects may consider comparable arrangements for remote I/O communications, wireless infrastructure, traffic devices and other Ethernet-connected edge equipment.

The selection decision should begin with the number of protected links and the actual power required at each endpoint. The two-port version may fit small field enclosures or paired-device installations, while the four-port version reduces the number of individual protectors in a larger termination area. Neither option eliminates the need to coordinate network topology, cable shielding practices, grounding and upstream protection with the site’s overall electrical design.
