Here's how the RealSense D457 and D555 compare on interface, IP rating, and PoE:
D457 vs D555
| Attribute | RealSense D457 | RealSense D555 |
|---|---|---|
| Interface | GMSL2/FAKRA | Ethernet/RJ45 |
| IP rating | IP65 | IP65 |
| PoE | Not applicable (GMSL2/FAKRA connection; no PoE listed) | Yes — PoE provides device input power |
Key differences:
- Interface: The D457 uses a GMSL2/FAKRA data connection, which requires a host-side deserializer and supporting drivers. The D555 streams depth data over Ethernet/RJ45. - PoE: The D555 is PoE-powered — PoE provides the device input power, with USB also usable for power/debug/sync. The D457 has no PoE capability listed in the catalog; its power delivery would come through its GMSL2/FAKRA harness setup instead. store.real...store.realsenseai.com ↗“PoE provides device input power” store.real... +1store.realsenseai.com ↗“GMSL2/FAKRA data connection requires a host-side deserializer”store.realsenseai.com ↗“Ethernet/RJ45 streams depth data”
- IP rating: Both cameras share the same manufacturer-published IP65 enclosure rating, so they're equally suited for dust/water-protected deployments. store.real... +1store.realsenseai.com ↗“Manufacturer-published IP65 enclosure”store.realsenseai.com ↗“Manufacturer-published IP65 enclosure”
In short: if your system design uses an Ethernet backbone with PoE (common for longer cable runs and simplified wiring), the D555 fits directly. If you're integrating with a GMSL2 host (e.g., an automotive-style or deserializer-equipped Jetson carrier), the D457 is the match — but plan for the host-side deserializer requirement.
