General Description
ES811 is a 4G (Cat.M1& NB-IoT) GPS Tracker for vehicle. It reports location information via
TCP/UDP with configurable intervals. ES811 has max 4 inputs which can be used to detect
sensors and max 4 outputs to control fuel or the vehicle starter. It also has max 3 UARTs to
connect an external device to transmit user data to a server. It can work in humid
environment because of its waterproof design.
Main Functions
⚫ Tracking: It sends GPS (Location, speed) and sensors (if any) information to your application server with configurable report interval (moving or stationary).
⚫ Geofence: It supports circle and polygon setting.
⚫ Backup Battery (optional): With a backup battery (300mAh), the device sends a tamper message if the main power supply harness is disconnected.
⚫ Over Speed Limit: Reports over-speed limit.
⚫ 3-Axis Accelerometer: With a built-in 3-axis accelerometer, the device can detect trip start/trip end, and to report harsh braking, harsh acceleration, and impact.
⚫ Storing Message: The device stores up to hundreds of messages while there is no GSM signal.


⚫ Low Voltage Detection (optional): Device switches to deep sleep mode if supply voltage drops
below a threshold.
⚫ Power Saving Mode: Device periodically wakes up and sleeps when vehicle engine is OFF.
⚫ Expand other peripherals: Plenty of IOs, UARTs and AD to accomplish custom’s requirement.
⚫ OTA (Over the Air): The device’s firmware can be upgraded via TCP.
⚫ Waterproof Case: IPX65 waterproof.
