The Waterproof Outdoor Digital Signage's waterproof and moisture-resistant features are its core design highlights, as demonstrated below:

1. Protection Rating Standards
IP68 Waterproof and Dustproof: Select models can operate continuously in water up to a depth of 1.5 meters for 30 minutes, completely blocking dust intrusion and suitable for heavy rain or high humidity environments.
IP55/IP65 Protection: Basic models are resistant to low-pressure water jets and dust accumulation, meeting the requirements of general outdoor use.

2. Materials and Structural Design
Sealed Interface Technology: Utilizing an M12 waterproof connector, a C3 HDMI port, and a rust-resistant galvanized steel housing, the internal circuitry is completely sealed from moisture.
Nano-Coating and Bonding: The screen is coated with a water-repellent nano-coating, combined with optical bonding technology to reduce water stains and enhance display clarity.

3. Extreme Environment Adaptability
Wide Operating Temperature Range: Operates stably from -40°C to 75°C, and features automatic temperature control systems (such as fan cooling or a cold start function). Anti-condensation design: Select models automatically adjust ventilation using an internal humidity sensor to prevent condensation caused by temperature fluctuations.

4. Intelligent Protection Mechanism
Remote Monitoring: Supports real-time monitoring of internal temperature, humidity, and voltage status, automatically triggering protective measures (such as power outages or alarms) when anomalies occur.
Modular Waterproof Expansion: A waterproof antenna port and sealed slots (such as Mini PCI-E) allow for compatibility with 4G/Wi-Fi modules, maintaining overall protection even when expanded.

These features enable long-term use in humid, dusty environments, such as ports and transportation hubs, or in locations with drastic temperature fluctuations.
