Product Overview
Perimeter detection across unlit industrial sites, substations, and large outdoor compounds calls for something beyond a conventional IR camera. The DS-2TD2617-3/QA is a Hikvision HeatPro dual-lens thermal bullet camera that pairs a 160×120 VOx uncooled focal plane array thermal sensor with a 4MP optical module in a single weatherproof housing. With a thermal NETD below 40mK and a 50.0°×37.2° thermal field of view, the camera detects heat signatures in complete darkness, light smoke, and adverse weather conditions where standard cameras would fail to produce a reliable image. The optical module delivers 2688×1520 resolution video with up to 40m IR range for detailed identification footage once an alert is triggered. Supporting up to 8 VCA rules across line crossing, intrusion, region entrance, and region exiting – combined with active white light and audio alarms – the DS-2TD2617-3/QA suits critical perimeter monitoring at warehouses, utilities, industrial yards, and transport infrastructure.
Key Capabilities
Thermal Detection Independent of Light
The 160×120 VOx uncooled focal plane array sensor with NETD below 40mK detects heat signatures in total darkness, heavy shadows, and light obscurants. This makes the camera effective for perimeter monitoring where conventional IR cameras would produce unreliable or unusable footage.
4MP Optical Verification Module
The 1/2.7″ progressive scan CMOS optical sensor captures 2688×1520 video with a 4mm lens and 84.0°×44.8° field of view. With 120dB WDR and a minimum illumination of 0.0089 lux, it provides usable detail footage for event verification after a thermal alert has been triggered.
Active White Light and Audio Alarm
On detection, the camera can activate a white light strobe up to 40m and trigger one of 2 preset audio alerts or up to 6 user-importable voice alerts. This active deterrence response is linked to both VCA events and temperature exception triggers, enabling automated on-site intervention.
Thermal VCA with Up to 8 Rules
The thermal channel supports line crossing, intrusion, region entrance, and region exiting detection, with up to 8 simultaneous VCA rules configured across any combination of these types. Rules are evaluated against the thermal image, so lighting conditions do not affect detection reliability.
Temperature Measurement and Exception Alarms
The camera measures surface temperatures from -20°C to 150°C across up to 21 measurement rules (10 points, 10 areas, 1 line) with accuracy of ±8°C. Temperature exception alarms can trigger recordings, relay outputs, FTP uploads, or email notifications for process monitoring or fire-risk applications.
IP66 and TVS 6000V Protection
Rated IP66 for dust and water ingress resistance, the housing also incorporates TVS 6000V lightning protection, surge protection, and voltage transient protection. The camera operates from -40°C to 65°C, making it suitable for exposed outdoor installations in harsh Australian climates.
Best For
- Industrial Perimeter Monitoring: The thermal module detects intruders based on heat rather than reflected light, making it effective along fence lines, at loading docks, and across outdoor yards where lighting is minimal or absent.
- Critical Infrastructure Protection: Up to 8 configurable VCA rules on the thermal channel allow precise virtual boundaries around substations, water treatment facilities, and data centres without depending on ambient illumination.
- Temperature Monitoring with Alarm Linkage: With 21 temperature measurement rules and alarm output contacts, the camera supports early detection of overheating equipment or fire-risk areas in warehouses, switchrooms, or industrial processing environments.
- Adverse Weather and Low-Visibility Environments: The thermal sensor’s NETD below 40mK maintains detection performance in fog, light rain, and heavy shadows where standard IR cameras produce false negatives or degraded image quality.
Why Choose the DS-2TD2617-3/QA
Where a standard bullet camera with IR illumination depends entirely on reflected light to detect movement, the DS-2TD2617-3/QA uses a dedicated 160×120 VOx thermal sensor to detect heat signatures under any lighting condition. This dual-channel approach means the thermal module handles detection and alerting while the 4MP optical module with 120dB WDR and 40m IR range captures the verification footage needed for incident review. The onboard active deterrence, combining adjustable-frequency white light and configurable voice alerts, provides an automated response layer without requiring additional hardware. With TVS 6000V lightning protection, IP66 weatherproofing, and an operating range from -40°C to 65°C, the camera is built for demanding fixed outdoor installations. The DS-2TD2617-3/QA is available through Security Wholesalers as part of the Hikvision HeatPro thermal camera range, suited to installers specifying perimeter security at industrial, commercial, and critical infrastructure sites.
Buyer Decision Tips
Thermal Resolution and Detection Range: The DS-2TD2617-3/QA uses a 160×120 thermal sensor with a 3.1mm focal length and 5.48 mrad IFOV. At this resolution, the camera is suited to detecting human-sized targets across short to mid-range perimeter zones rather than long-distance surveillance corridors. If your site requires detection beyond 50-60 metres with high confidence, consider whether a higher-resolution thermal sensor would better suit the detection distance required for your specific boundary length.
Temperature Measurement Accuracy: The camera’s temperature measurement accuracy is ±8°C across the -20°C to 150°C range. This tolerance is adequate for detecting significant temperature anomalies such as overheating equipment or fire-risk hot spots, but it is not suited to precision industrial process monitoring where tighter measurement tolerances are required. Confirm the accuracy tolerance is acceptable for your intended temperature monitoring application before specifying this model.

Ideal Use Cases
Industrial Yard and Warehouse Perimeters
The thermal sensor detects intruders along unlit fence lines and loading areas regardless of ambient light. Up to 8 VCA rules let installers define multiple virtual boundaries around different sections of a large site perimeter simultaneously.
Electrical Substations and Utilities
The temperature measurement function monitors up to 21 rules across points, areas, and lines, enabling early detection of overheating switchgear or cable runs. Temperature exception alarms can trigger relay outputs or email notifications for maintenance teams.
Construction Site Boundaries
With no reliance on site lighting, the thermal module maintains perimeter detection across unlit construction sites after hours. The active white light strobe and configurable audio alarm provide an on-site deterrence response without requiring a monitoring centre to intervene.
Transport and Logistics Facilities
The 4MP optical module with 120dB WDR handles high-contrast conditions such as vehicle headlights entering a yard at night. The thermal channel continues to flag pedestrian movement independently, providing two complementary detection streams on a single camera.
Critical Infrastructure and Border Zones
Operating from -40°C to 65°C with IP66 and TVS 6000V lightning protection, the DS-2TD2617-3/QA withstands exposed coastal, remote, and climatically demanding installations where standard housing cameras would require additional protection enclosures.
Choosing the Right Model
- Choose this model if: Your site requires reliable perimeter detection in conditions where lighting cannot be guaranteed, and you want thermal-based VCA combined with a 4MP optical verification channel and active deterrence outputs in a single bullet housing.
- Choose a different model if: Your application requires detection across long distances exceeding 60-80 metres with high confidence, as a higher-resolution thermal sensor would provide a better-suited IFOV for those ranges.
- Choose a different model if: Temperature measurement accuracy tighter than ±8°C is required for precision process monitoring. This camera’s thermal module is suited to exception detection rather than industrial calibration-grade temperature measurement.
- Choose a different model if: The installation is purely indoors or in a fully lit environment where a standard IP bullet camera would deliver adequate detection at significantly lower cost.
FAQs
- How does the thermal module detect intruders differently from a standard IR camera?
The thermal module detects heat radiated by a subject rather than reflected infrared light. This means it does not require any illumination at all – no IR LEDs, no white light, and no ambient light. The 160×120 VOx sensor with NETD below 40mK can distinguish a person from a background even in total darkness, through light smoke or fog, and in conditions where a standard IR camera would produce a completely dark or washed-out image.
- What is the effective detection range of the thermal module on the DS-2TD2617-3/QA?
The thermal module uses a 3.1mm focal length with an IFOV of 5.48 mrad and a 50.0°×37.2° field of view. At this resolution and focal length, the camera is well suited to detecting human-sized targets at short to mid-range perimeter distances. Exact detection range depends on target size, temperature contrast, and environmental conditions, but the 160×120 resolution at this focal length is generally appropriate for zones up to approximately 40-60 metres.
- Can the DS-2TD2617-3/QA measure the temperature of specific equipment or surfaces?
Yes. The camera supports 21 configurable temperature measurement rules across 10 point measurements, 10 area measurements, and 1 line measurement. The measurable range is -20°C to 150°C with an accuracy of ±8°C. Temperature exception alarms can be configured to trigger recording, relay output, FTP upload, or email notification when a reading exceeds a defined threshold.
- How does the active alarm response work when a VCA event is detected?
When a thermal VCA rule is triggered, the camera can activate its white light strobe at a range of up to 40m with an adjustable flashing frequency and simultaneously trigger an audio alarm. There are 2 preset voice alerts and up to 6 user-importable voice alerts that can be assigned across VCA and temperature exception alarm types. These responses can also be configured to activate relay output contacts for integration with external alarm systems.
- Does the DS-2TD2617-3/QA support PoE powering?
Yes. The camera supports PoE powering via IEEE 802.3af (Class 3) with a maximum consumption of 6.5W over PoE. It also accepts 12VDC ±25% via a 5.5mm coaxial power connector. For outdoor installations without a nearby power source, PoE simplifies deployment by delivering both power and data over a single Cat5e or Cat6 cable.
- What video streams does the optical module output?
The optical module streams up to 2688×1520 at 25fps (50Hz) or 30fps (60Hz) on the main stream, with sub-stream options down to 704×576. Video compression uses H.265 or H.264 on both main and sub-streams, with MJPEG also available on the sub-stream. The thermal module outputs a separate stream at up to 1280×720 upscaled from the 160×120 sensor at 25fps.
