Description:
G202 4G LTE Gate Controller—4G Upgraded, Faster & More Stable Remote Control
The G202 4G LTE Gate Controller is a next-generation wireless access control device, fully optimized for 4G LTE networks with VoLTE support. It replaces outdated 2G GSM gate openers and traditional remotes/keys, providing a faster, more reliable, and long-term usable solution for remote gate, door, barrier, and industrial equipment control.
Key Functional Highlights
Full-band 4G LTE (B1/B2/B3/B4/B5/B7/B8/B20/B28/B38/B40/B41/B66) with VoLTE & data function required. Faster connection, stronger anti-interference, stable signal in weak coverage areas, no 2G phase-out risk, future-proof for long-term use.
100% Free Call Activation (Zero Cost)
Authorized users dial the Nano SIM number; the device rejects the call on the first ring and triggers the relay instantly. No call charges, no monthly fees, no data plan required for basic use.
200 Authorized Users with Name Management
Supports up to 200 authorized phone numbers (001–200). Add/delete/check users via simple SMS commands; assign uppercase usernames (max 10 chars) for easy identification and batch management.
Caller ID Security & Flexible Access Modes
Strict caller ID verification—only pre-approved numbers can activate the device, unknown callers are ignored. Supports authorized-only access (default) or all-call open modes for different scenarios.
Full SMS Remote Control & Real-Time Status Feedback
Complete SMS command system: change password, manage users, set relay time (0–999s), trigger relay ON/OFF, check real-time device status (4G signal strength, relay status, user count, etc.). Customizable SMS confirmations for relay actions, keep you informed anytime.
Power Failure Memory Function
Automatically remembers the relay status before power outage and resumes the same state when power is restored, ensuring uninterrupted operation for security and industrial equipment.
Dual Control: 4G Remote + Local Wired Switch
Dual backup control: 4G free call/SMS remote control + local wired push button (dry contact). Works reliably even in weak 4G signal or power outage situations.
DC 9–36V Wide Voltage & Low Power Consumption
Compatible with AC DC7-36V power supply (12V/24V systems), max current 50mA, average current only 25mA. Low energy consumption, stable performance for long-term use.
Compact Industrial-Grade Design
Mini size (96.5×50×31.5mm),lightweight (88g),easy wall-mounted installation. Operating temperature -10°C ~ +60°C, relative humidity 10–90% RH. CE/RoHS/FCC certified, durable for outdoor and industrial harsh environments.
How It Works
1.Insert a 3V Nano SIM card (must support 4G VoLTE & data function).
2.Connect DC 9–36V power and wire relay terminals (NO/COM/NC) to your gate motor, electronic lock, or industrial equipment.
3.Add authorized phone numbers
via SMS commands: 1234#TEL00XXXXX#001#.
4.Dial the SIM number from an authorized phone → free activation, relay triggers instantly.
5.Use SMS commands for remote ON/OFF, status check, or user management anytime, anywhere.
