Long Standby 4G GPS Tracker

When you need reliable long-term tracking for vehicles, trailers, containers and assets in North America and Europe, the GPT49-EG ultra-long standby 4G GPS tracker delivers a practical wire-free solution. Designed for scenarios where frequent battery replacement or hard-wiring is not feasible, this wireless asset tracker works for car rental fleets, stolen vehicle recovery, logistics cargo tracking, construction equipment monitoring and high-value unattended assets. Its compact, concealable housing makes it easy to mount and hide on target objects, ideal for businesses seeking hands-off long-term location supervision.

Supports multi-constellation GNSS including GPS, Beidou and GLONASS for satellite-level positioning accuracy. Where satellite signals are blocked inside containers, warehouses or dense urban areas, built-in Wi-Fi positioning serves as a fallback to obtain valid coordinates when GNSS reception fails.

Supported cellular networks cover wide-range 4G LTE FDD / LTE TDD plus 2G GSM. Location data is transmitted over cellular network to Keelin tracking platform or third-party integrated systems. Users can access real-time position and historical track records via web dashboard, mobile APP.

Powered by an integrated 6400 mAh zero-self-discharge disposable lithium-manganese battery, the unit achieves up to 4–year standby runtime when configured for one daily position upload. Deep-sleep power-saving logic cuts idle current drastically and eliminates frequent battery-replacement work for remote or hard-to-reach assets.

Two core configurable operating modes:

• Ultra–Long Standby Mode: The device stays in deep sleep most of the time and wakes up on pre-set timer to report location. While asleep, it cannot receive real-time commands. pending instructions will be executed once the tracker wakes up. This mode applies to routine long-term asset supervision.
• Emergency Tracking Mode: Triggered by platform, APP or SMS command. The tracker suspends deep-sleep cycles and uploads location data continuously for a defined duration for live recovery scenarios, before automatically returning to long-standby mode.

Vibration / motion-based wake-up is a core anti-theft feature optimized for battery saving. When running under ultra-long standby mode, the tracker keeps deep sleep to conserve power while assets remain stationary. Once built-in motion sensor detects vibration or movement, the device wakes up immediately and sends updated location to the cloud without waiting for its scheduled reporting interval.

When operating in emergency tracking mode, the sensor additionally generates vibration, collision and drop alarms. This function ensures you get instant location alerts upon unauthorized movement for vehicles, containers and construction equipment.

Equipped with an integrated light sensor for physical tamper protection. The tracker is supposed to be mounted with its light-sensor side facing against a surface in concealed installation. When the device is removed, ambient light hits the sensor. The hardware immediately wakes the sleeping unit and pushes a removal / tamper alarm to the Keelin platform and pre-configured administrator SMS numbers. This feature offers critical protection against attempts to disable the tracker by physical removal.

Thanks to intelligent power management including vibration wake-up, it balances multi-year battery longevity and responsive event alerts, so you get reliable tracking without frequent SIM data waste or on-site servicing. It seamlessly pairs with the Keelin tracking platform for unified device management, open-API integration for third-party systems. Whether securing rental cars, overseeing shipping containers, or protecting construction machinery, GPT49-EG is a robust long-standby wireless GPS tracker built for North-American and European asset-tracking demands.
