iStartek - PT21

The PT21 Smallest GPS Tracking Device by an established OEM is a compact, Plaspy compatible GPS tracker designed for pets, small assets and discreet personal tracking. Combining GPS, LBS and Wi‑Fi hybrid positioning with 2G/GPRS communications, the PT21 delivers reliable real‑time tracking, voice monitoring and SOS functionality in a tiny, waterproof package ideal for on‑the‑move protection.

Engineered for long standby and rugged daily use, the PT21 is a practical choice when you need accurate location fixes, simple integration with Plaspy, and low ongoing overhead (no manufacturer server fee — only SIM/data charges). Its two‑way audio, intelligent power management and geofence/alert features make it straightforward to add compact asset protection and anti‑theft capabilities to your Plaspy telemetry and reporting workflows.

Key Highlights

• Plaspy compatible: standard TCP/UDP/SMS reporting for smooth integration into Plaspy real‑time tracking and alerts.
• Hybrid positioning (GPS + LBS + Wi‑Fi) for faster fixes and better indoor/outdoor coverage.
• Two‑way audio and voice monitoring plus an SOS emergency call button for discreet personal safety and remote checks.
• Long standby battery life (1000mAh Li‑ion — up to 15 days standby) and intelligent power management for extended deployments.
• Rugged, IP67 waterproof housing for use on pets, luggage and during sports activities.
• Historical route playback up to 3 months, scheduled reporting by time/distance/mileage, geo‑fence and low‑battery alarms.
• Low operational overhead — uses existing 2G/GPRS networks and requires only a SIM card (GPRS recommended, minimum ~30MB/month).

How It Works with Plaspy

The PT21 communicates location and status over 2G/GPRS using TCP, UDP or SMS. When paired with Plaspy, those standard feeds provide live position updates, alerts and route history for monitoring, reporting and incident response. Plaspy ingests the device’s telemetry so you get continuous real‑time tracking and event notifications without extra middleware.

• Real‑time location and telemetry updates via GPRS (TCP/UDP) or SMS to Plaspy for immediate map visualization.
• Two‑way audio and SOS alerts — use Plaspy to surface emergency events and link to recorded location data.
• Geo‑fence events, low‑battery alarms and scheduled reporting (time, distance, mileage) appear as actionable alerts in Plaspy.
• Historical route playback (up to 3 months) available within Plaspy using the device’s stored reports for analysis or audit trails.
• Standard reporting formats and TCP/UDP channels mean simple configuration on Plaspy’s device setup page — no proprietary protocol required.

Technical Overview

Use Cases

• Pet tracking (cats, dogs) with discreet size, waterproof housing and long standby for day‑to‑day use.
• Discreet personal safety and lone‑worker protection — SOS button and two‑way audio for emergency checks.
• Luggage and small asset protection — attach to bags or equipment to provide anti‑theft alerts and route history.
• Outdoor and sports activities where a small, rugged tracker is required and occasional telemetry updates suffice.
• Small equipment and tool tracking in a light fleet or site context — complements Plaspy’s fleet management for small assets.

Why Choose This Tracker with Plaspy

For organizations and individuals who need a compact, reliable GPS tracker that integrates with Plaspy for real‑time tracking and telemetry, the PT21 offers a pragmatic balance of size, battery life and functionality. Its hybrid positioning and fast GNSS TTFF deliver dependable location fixes, while two‑way audio and SOS add safety and anti‑theft utility. The IP67 rating and magnetic charging make it easy to deploy on pets, luggage and portable assets without frequent maintenance.

Because the PT21 uses common TCP/UDP/SMS protocols and standard GPRS reporting, integration into Plaspy is straightforward — Plaspy can display live positions, generate geofence and low‑battery alerts, and replay up to three months of routes for audits or investigations. If your deployment requires additional telemetry such as fuel monitoring, ignition or immobilizer control, or Bluetooth sensor support, Plaspy supports other compatible trackers designed for those functions; the PT21 is optimized for small‑form‑factor tracking, voice monitoring and emergency alerts.
