The BL370 efficiently implements video surveillance, access control, intrusion detection, and alarm functions for building security with high-performance hardware and flexible software, suitable for commercial, residential, and industrial scenarios.

Case Details

1. Overview

The ARMxy BL370 series embedded computer(Rockchip RK3562/RK3562J, up to 2.0GHz, 1TOPS NPU) is ideal for building security systems, integrating video surveillance, access control, intrusion detection, and alarm functions. Its industrial-grade design (-40~85°C, IP30, EMC Level III) ensures reliable operation, supporting Linux/Ubuntu, Node-RED, and cloud platform integration.

2. Function Implementation

Video Surveillance:
- Hardware: Quad-core Cortex-A53 + GPU processes 1080p/4K video; 1TOPS NPU supports face/license plate recognition; HDMI, USB, 4G/5G modules for video transmission.
- Software: Ubuntu + OpenCV for AI algorithms, RTSP/MQTT for cloud upload (e.g., Alibaba Cloud).
- Application: Multi-channel camera monitoring, real-time face/license plate recognition, local storage or remote viewing.
Access Control:
- Hardware: X-board (RS485/RS232) connects RFID readers, Y-board (DI/DO) controls locks; Ethernet/4G for networking.
- Software: BLIIoTLink integrates Modbus/MQTT, Node-RED for access logic.
- Application: Face/card-based door access, events uploaded to property management platform.
Intrusion Detection:
- Hardware: Y-board connects PIR/vibration sensors; NPU analyzes anomalies.
- Software: Node-RED processes sensor data, MQTT uploads to cloud.
- Application: Detects unauthorized entry, reduces false alarms with video integration.
Alarm Function:
- Hardware: Y-board (relay/PWM) controls buzzers/lights; 4G for notifications.
- Software: BLIIoTLink sends alarms to SCADA, BLRAT for remote management.
- Application: Triggers sound/light alarms on anomalies, notifies security personnel.
