Network Testing Tools

Hardware network emulators, packet capture appliances, and QA infrastructure for network products.

AV & Media Systems

Instant audio/video playback devices, digital signage, and multi-monitor presentation systems.

Hardware Design

Custom enclosures, 3D-printed components, and purpose-built hardware for professional deployment.

Our Philosophy

The principles that guide everything we build.

1

Appliance Simplicity

機器のシンプルさ

Products should work like dedicated appliances — power on, it works. No babysitting, no general-purpose OS complexity.

2

Hardware Trust

ハードウェアの信頼性

Physical buttons and dedicated devices give operators tactile feedback and repeatability that software alone cannot match.

3

Field-Ready Design

現場対応設計

Every product must survive real-world conditions: mobile battery power, harsh environments, and ad-hoc deployments.

4

Open Standards

オープン標準

PCAP, ECHONET Lite, USB, HDMI — we build on standards so our tools integrate with your existing workflow.
