In high-stakes environments—airports, border perimeters, industrial facilities—security demands technology that doesn’t sleep. Enter DS-2TX3636-35A, a thermal smart linkage tracking system built by Hikvision that combines fixed and PTZ modules to monitor, detect, and follow moving targets in challenging conditions. In this article, you’ll discover its features, benefits, real-world applications, and how to deploy it most effectively.
From here on, “DS-2TX3636-35A” will refer to that exact model. Let’s dive into what makes it stand out.
What is DS-2TX3636-35A?
DS-2TX3636-35A is a thermal smart linkage tracking system comprised of:
- A fixed thermal camera module (wide view)
- A PTZ (Pan-Tilt-Zoom) camera module
- Smart linkage between the two for automated tracking
The design allows the fixed camera to detect motion over a wide area, then hand off tracking responsibilities to the PTZ unit for detailed following and zoomed-in observation.
Key use cases include perimeter protection of high-security zones, infrastructure monitoring, and large-scale installations where continuous, automated tracking is essential.

Smart Features & Detection Logic
Master-Slave Linkage & Tracking Modes
- Automatic master-slave tracking: The system autonomously shifts focus from fixed to PTZ camera when motion is detected.
- Manual master-slave tracking: Users can click a region in the fixed camera’s view via client software; the PTZ then centers on that region.
- Linkage rules: You can configure triggers like intrusion detection or line crossing to initiate tracking.
Multi-target & Smart Switching
- Supports tracking up to 30 targets simultaneously.
- Allows automatic target switching when a new or higher-priority target appears, with less than 1 second of delay.
- Sensitivity, detection thresholds, and tracking time are configurable per use case.
Image Processing
- Uses adaptive AGC, DDE, and 3D DNR to improve clarity.
- Offers 15 palettes for thermal display colorization and contrast tuning.
- Supports multiple video compression standards and streams.
Real-World Applications & Use Cases
1. Perimeter Security in High-Security Sites
For prisons, border fences, airports, and critical infrastructure, DS-2TX3636-35A helps detect intrusions early and follow them continuously. Its thermal module can catch movement at night or through smoke/fog, while the PTZ module provides visual confirmation.
2. Industrial & Utility Facilities
Power plants, oil & gas sites, and storage yards benefit from this hybrid tracking in large open areas, where manual patrol is inefficient.
3. Wildlife / Preservation Monitoring
In national parks or protected zones, thermal tracking helps detect unauthorized human/vehicle presence without intrusive lighting.
4. Smart City & Urban Infrastructure
Use for road crossings, tunnels, or restricted zones in smart city setups, where automated detection and tracking reduce human intervention.
Example Scenario: In an airport perimeter, a guard tower fixed camera detects motion at 250 m using the thermal sensor. DS-2TX3636-35A hands off the target to the PTZ for zoomed-in visual verification, triggering alarms and logging the event — all without human operator involvement until needed.
Key Advantages & Limitations
