TSP-1-BUS Touchscreen Keypad

Introduction

TSP-1-BUS is a hardwired touchscreen keypad that connects to Climax’s Hybrid Panel via RS485 BUS, providing reliable security control and smart home access. Featuring a 7” full-color, high-resolution touchscreen, it delivers intuitive and fast operation for arming/disarming the system, automation control, and video verification through IP cameras or video phones.

🚪 Key Features

🔒 Hardwired BUS Communication (RS485)
Ensures real-time stability and redundancy via BUS topology. Multiple devices can connect simultaneously for scalable system integration.
📱 7” Touchscreen Display
High-resolution user interface for intuitive security and automation control.
🏠 Wi-Fi Smart Home Integration
Enables automation device control and IP camera streaming once connected to a wireless network.
📹 Video Verification
Stream footage from IP cameras and video phones directly on the keypad for immediate context.
🧱 Flexible Installation
Wall-mounted or tabletop, suitable for different residential/commercial environments.

🧑‍💻 My Role

I independently planned and implemented the entire BUS communication module, including:

Developed custom RS485 protocol:
- Handshake & Acknowledgment
- Encrypted packet structure
- Custom packet framing & error detection (like TCP/UDP)
Built core system logic and integration with Hybrid Panel
Coordinated with backend and hardware teams for end-to-end system validation
Developed UI workflow and network logic in a scalable MVP architecture

⚙️ Tech Stack

Architecture: MVP
Hardware Communication: RS485 (custom protocol similar to TCP/UDP)
Network: TCP/UDP, HTTPS, MQTT
Multimedia: RTSP, H.264, FFMpeg
Testing: mockito (Java), mockK (Kotlin)

📡 “In TSP-1-BUS, I built a robust RS485 communication stack from the ground up to ensure hardwired stability with real-time performance.”
