4G LTE / WiFi GPS Torch Guard Tour System

The YD-Z900E 4G LTE / WiFi GPS Torch Guard Tour System is an all-in-one patrol reader designed for high-security environments, large industrial facilities, and demanding outdoor night shifts. Combining high-speed 4G connectivity, local WiFi support, and high-precision GPS intelligence, this device allows supervisors to track guards' live locations on electronic maps while receiving instantaneous patrol status updates.

Engineered for extreme durability, the YD-Z900E features a rugged shockproof housing capable of withstanding drops and harsh field conditions. With a high-capacity rechargeable battery, an integrated tactical flashlight, a clear LCD screen, and advanced custom event logging, the YD-Z900E offers comprehensive security oversight for round-the-clock patrol operations.

Visualized Route Tracking (GPS + Electronic Map)

The integrated GPS module tracks coordinates outdoors, feeding real-time location data to the administration center's electronic map, ensuring patrol route integrity and guard safety.

Advanced Event Management & Reporting

The YD-Z900E supports up to 500 customizable event logs. When a guard encounters a facility issue (like a broken fence or water leak), they can quickly select the pre-programmed event via the LCD interface and transmit it instantly to the cloud.

High-Performance 3,000mAh Power Station

Equipped with a 3,000mAh battery, the device supports up to 27 active working hours and 68 standby hours. It easily powers both the 4G communication modules and the tactical flashlight on a single charge.

Built-in Patrol Alarm & Shift Reminders

Administrators can configure local alarm reminders through the cloud software. The YD-Z900E will vibrate and flash screen alerts to remind security guards precisely when their patrol shift is scheduled to begin.

Large-Scale Industrial Parks & Campus Patrols

Utilizes integrated 4G and GPS tracking to monitor guard routes across sprawling campuses, ensuring patrol compliance in every sector via visual electronic maps.

Utility Plants & Equipment Inspection

The customizable event logging allows maintenance patrols to instantly report machinery faults, pipeline leaks, or safety hazards right from the checkpoint.

Extreme Weather & High-Risk Security Sites

With its -40°C to 80°C operating range and IP67 rating, this device is suitable for harsh environments like oil fields, remote mines, and coastal perimeters.

Q1: How does the custom event logging function benefit our supervisors?
A: The YD-Z900E allows guards to report site status. If they find a security breach or broken lock, they select the corresponding pre-set "Event" on the LCD menu, and a pop-up alert immediately appears on the cloud administration dashboard.

Q2: Does the GPS feature work indoors or in basements?
A: GPS signals generally require line-of-sight with satellites and operate outdoors. For indoor or basement patrols, the system relies on physical RFID checkpoint tags for location verification. When the guard steps outside, the GPS automatically re-establishes tracking.

Q3: What happens if both 4G and WiFi networks are unavailable?
A: The YD-Z900E automatically switches to offline mode, saving up to 80,000 patrol logs inside its secure memory. As soon as the guard enters an area with 4G network coverage or local WiFi, all cached data instantly uploads to the cloud server.
