T221 4G LTE Cloud Dashcam: 2K Dual-Channel Security for North America (US-CA-MEX) | Manufacturer Factory | OEM ODM | CAT4

Advantages：

Dedicated North American 4G LTE Connectivity

Stay connected reliably across the continent. The T221 features an integrated CAT4 4G LTE module with extensive frequency band support specifically for North American carriers (FDD-LTE: B2/B4/B5/B12/B17/B26/B66/B41). This ensures seamless access to all advanced cloud features and remote monitoring throughout the US, Canada, and Mexico.

Unbreakable TS Video Format & G-Sensor Protection

Your evidence is always safe. Unlike traditional formats, the T221 records in TS Video Format, saving data second-by-second. If a collision occurs causing a sudden power failure or memory card ejection, the video file remains uncorrupted. Combined with a built-in G-Sensor, collision footage (7s before and 7s after) is automatically locked to the SD card and instantly uploaded to the cloud.

Comprehensive 4G Remote Cloud Services

Stay connected to your vehicle via the mobile app. The built-in 4G LTE module allows you to access Remote Live View (front and rear), playback stored videos, backup important footage, and receive push notification alerts for specified events—anywhere, anytime. It also supports Over-The-Air (OTA) remote firmware updates for effortless maintenance.

Intelligent Parking Modes & Low Power Consumption

Protect your car 24/7 without draining the battery. When wired via OBD or fuse box, the T221 enters Anti-theft Sleep Mode (drawing just 4.5mA). If vibration or an unauthorized GPS movement is detected, it wakes up instantly to record, upload to the cloud, and alert your phone. Alternatively, activate Time-Lapse Mode (1-3fps) for continuous, space-saving surveillance. The system includes automatic low-voltage shutdown protection.

Enhanced Two-Way Intercom & Voice Control

Communicate effortlessly. The built-in high-quality SPK BOX (8Ω/1W) and microphone support two independent ADC channels with advanced echo and noise cancellation, enabling clear two-way voice communication between the app and the driver. Furthermore, "Voice Capture" allows drivers to safely command the dashcam to take photos or short videos while driving.

Pinpoint GPS + GLONASS Tracking

Monitor your vehicle's exact whereabouts. Dual-system GPS and GLONASS (with AGPS support) provide rapid, highly accurate real-time location tracking. Generate driving reports containing route history and travel time, and receive voice and app alerts if the vehicle exceeds predefined speed limits.

Multi-Function SOS & Breathing LED Indicator
