SpinetiX HMP400 – Mission-Critical 4K Digital Signage Player

Product Overview

The SpinetiX HMP400 4K digital signage player is a mission-critical media player built for commercial installations that require wired-network reliability and 24/7 operational durability. It delivers DCI 4K and 4K UHD playback over HDMI 2.0 or DisplayPort 1.2, and can be powered via PoE+ (802.3at) or USB-C Power Delivery, removing the need for a dedicated power outlet in most ceiling and wall-mount scenarios. The fanless commercial-grade digital signage player is manufactured in Germany, engineered in Switzerland, and ships with a 3-year warranty extendable to 5 years. TAA compliant for government and institutional procurement, it pairs DSOS — SpinetiX’s purpose-built secure operating system — with lockable connectors and IP40 protection for dependable long-term deployment.

Product Description

The SpinetiX HMP400 is a PoE+ fanless 4K player designed for organizations that prioritize wired network security and straightforward installation over wireless flexibility. Powered by an Intel Atom x5-E3930 processor and 4GB LPDDR4-2400 memory, the HMP400 handles DCI 4K (4096x2160) and 4K UHD (3840x2160) content natively, with support for 1080p and custom resolutions on a wide range of commercial displays. The HDMI 2.0 lockable output and DisplayPort 1.2 option via lockable USB-C ensure the player stays physically connected in high-traffic and public-facing installations. PoE+ (802.3at) power delivery means the HMP400 can receive both data and power over a single Ethernet cable from a compatible switch or injector — a practical advantage for ceiling-mount and display-back installations where running separate power is costly or disruptive. The DSOS operating system incorporates Secure Boot, cryptographically signed firmware, and TPM hardware security to protect against unauthorized content modification and maintain system integrity across distributed deployments. Frame-accurate synchronization (±1 frame) is supported across multiple HMP400 units, enabling synchronized content on multi-display installations without additional hardware. The industrial eMMC 5.1 MLC NAND storage combined with a supercapacitor-backed RTC (±1 min/month, 30-day power-off backup) ensures scheduled content plays accurately even after power interruptions. At 660g with an IP40 dust protection rating, the HMP400 is compact enough for discreet mounting while meeting commercial-grade signage standards. It is manufactured in Germany, engineered in Switzerland, and is fully TAA compliant, making it eligible for U.S. government, education, and federally funded AV procurements. The 3-year included warranty is extendable to 5 years for longer lifecycle coverage.

Technical Specifications

Frequently Asked Questions

Q: What is the difference between the HMP400 and the HMP400W?

The HMP400 connects to the network via wired Ethernet 1GbE only. The HMP400W adds a built-in IEEE 802.11ac Wave 2 2x2 MIMO Wi-Fi module for wireless connectivity. All other hardware specifications are identical. If your installation has reliable wired Ethernet at the display location, the HMP400 is the more cost-effective choice.

Q: Can the HMP400 be powered over Ethernet?

Yes. The HMP400 supports PoE+ (802.3at), allowing it to receive both data and power over a single Ethernet cable from a compatible network switch or midspan injector. USB-C Power Delivery 2.0 is also supported as an alternative power source.

Q: Is the HMP400 certified for government procurement?

Yes. The HMP400 is TAA compliant, manufactured in Germany, and engineered in Switzerland, making it eligible for U.S. government, federal, and GSA schedule procurement.

Q: Does the HMP400 support multi-player synchronization?

Yes. The HMP400 supports frame-accurate synchronization (±1 frame) across multiple players, enabling synchronized content playback on multi-display installations without dedicated sync hardware.

Q: Where can I purchase the SpinetiX HMP400?

The HMP400 is available at Creation Networks, an authorized SpinetiX reseller for commercial AV and digital signage solutions.
