Altronix PACE1PRMTHT Hi-Temp PoE/PoE+ IP Extender over CAT5e
The Altronix PACE1PRMTHT is a two-unit active Ethernet extender that stretches 100Mbps full-duplex data and IEEE 802.3af/at PoE power up to 500 meters over a single CAT5e run — without requiring a separate power supply at the remote end. If you're commissioning a perimeter camera or gate controller that sits beyond the 100-meter limit of standard Ethernet and you don't want to trench conduit for a power feed, the PACE1PRMTHT is the direct answer. Its high-temperature receiver rating of 75°C sets it apart from commodity extenders that fail in rooftop enclosures or unconditioned industrial cabinets.
Overview
Security installations routinely place cameras, intercoms, and access readers at distances that exceed the 100-meter Ethernet specification. Rather than running fiber (which requires separate media converters and power) or coax-based solutions (which require encoder/decoder pairs and lose native IP), the PACE1PRMTHT keeps everything on standard RJ45 infrastructure while adding range. Power for the entire link originates from a standard midspan injector or PoE-capable switch port — no local outlet, no separate transformer. The transceiver (remote) unit draws its operating power from the receiver over the extended cable run, so the only wiring you need between the two units is the CAT5e cable you're already pulling.
The pair operates at 100BaseT, which aligns with the actual throughput requirements of the vast majority of commercial IP cameras, access panels, and intercoms deployed today. For IP surveillance cameras and edge devices that stream H.264 or H.265 at 4–12 Mbps per channel, 100Mbps full-duplex is not a bottleneck. The PACE1PRMTHT belongs to Altronix's Altronix PoE and power distribution line, which is built around physical security infrastructure.
Key Features
- 500-Meter CAT5e Reach: Extends both data and PoE power five times beyond the standard 100-meter Ethernet limit. On a warehouse perimeter or large campus, that single cable run can cover a loading dock camera or parking lot access reader without any intermediate equipment room.
- IEEE 802.3af/at PoE and PoE+ Input: Accepts standard PoE (up to ~15W delivered) or PoE+ (up to ~30W delivered) from the upstream switch or midspan injector — no configuration required. This means most IP cameras, IP intercoms, and card readers with PoE requirements are powered without any additional hardware at the remote end.
- Transceiver Powered from Receiver: The remote transceiver unit draws operating power across the CAT5e from the receiver unit. There is no local power wiring required at the far-end device — just RJ45 in, RJ45 out.
- 100Mbps Full-Duplex Data Rate: Full-duplex 100BaseT throughout the extended link. You get symmetrical upstream and downstream bandwidth — important for cameras that handle bidirectional PTZ commands, two-way audio, or ONVIF event subscriptions alongside the video stream.
- High-Temperature Receiver Rating (-40°C to 75°C): This is the specification that earns the 'HT' suffix in the model number. Standard extender electronics typically derate or fail around 60°C — the PACE1PRMTHT receiver is rated to 75°C, making it viable in outdoor NEMA enclosures, rooftop equipment boxes, and unconditioned industrial spaces where summer ambient temperatures easily reach 50–60°C inside an enclosure.
- Wide Cold-Temperature Range (-40°C to 60°C on Transceiver): The remote transceiver is rated to operate at -40°C — relevant for outdoor camera installations in northern climates where winter temperatures can push well below -20°C inside unheated housings.
- Compact Form Factor (3.5
