Product Overview
Detecting elevated temperatures before they escalate into fire events is the primary purpose of the DS-2TD2137T-4/QY, a thermographic network bullet camera from Hikvision suited to industrial perimeters, outdoor storage yards, waste processing facilities, and fuel handling areas. Built around a 384×288 Vanadium Oxide Uncooled Focal Plane Array sensor with a 17 um pixel pitch and a NETD of 35 mK or less, the camera resolves minor thermal variations with precision. Featuring a 4.4 mm lens with an F1.0 aperture, it covers a 90 degree by 65.3 degree field of view and supports temperature measurement across 21 configurable rules spanning a range of -20 degrees C to 550 degrees C. It also incorporates smoking detection algorithms and video content analysis for human and vehicle classification at ranges of 28 m and 84 m respectively. Housed in an IP67 and IK10-rated enclosure rated for operation from -40 degrees C to 65 degrees C, it is built for continuous outdoor deployment in demanding conditions.
Key Capabilities
Wide-Range Temperature Measurement
With 21 configurable measurement rules covering points, areas, and line zones, the camera monitors temperatures from -20 degrees C to 550 degrees C with an accuracy of plus or minus 2 degrees C or plus or minus 2 percent, enabling precise exception alarm thresholds for industrial fire prevention workflows.
High-Sensitivity Thermal Sensor
The VOx Uncooled Focal Plane Array sensor delivers a NETD of 35 mK or less at 25 degrees C with an F1.0 aperture, meaning the camera can detect minute temperature differences that would be invisible to standard optical cameras, even in complete darkness or through smoke.
Smoking Detection Algorithm
An onboard smoking detection algorithm identifies smoke signatures independently from temperature thresholds, giving early warning before flames or significant heat buildup occur. This is particularly valuable for outdoor stockpiles, recycling yards, and facilities with combustible materials.
VCA with Human and Vehicle Classification
Supports 8 VCA rules across 4 rule types including line crossing, intrusion, region entrance, and region exiting, with human detection effective to 28 m and vehicle detection to 84 m. This allows the camera to distinguish between unauthorised personnel and passing vehicles without relying on visible light.
Rugged Industrial Housing
Rated IP67 for dust and water ingress protection, IK10 for impact resistance, and TVS 4000V lightning protection, the bullet housing is designed for pole and wall mounting at exposed outdoor positions including perimeter fence lines, rooftops, and loading dock approaches.
10-Year Detector Guarantee
Hikvision backs the thermal detector with a 10-year guarantee, reflecting the long operational lifespan expected in permanent industrial installations where replacement access is difficult and downtime for critical monitoring points is unacceptable.
Best For
- Industrial Fire Prevention: Temperature exception alarms covering up to 550 degrees C with 21 configurable measurement rules make this suited to monitoring conveyor belts, electrical substations, chemical storage, and waste processing areas where heat anomalies signal fire risk.
- Outdoor Perimeter Monitoring Without Lighting: Thermal imaging operates independently of ambient light, allowing effective human and vehicle detection at night or in low-visibility conditions without any IR illuminators or external lighting infrastructure.
- Smoke Detection in Open Yards: The onboard smoking detection algorithm is designed for open outdoor environments such as timber yards, landfill sites, and recycling facilities where conventional smoke detectors are impractical.
- Harsh Environment Deployments: With an operating range of -40 degrees C to 65 degrees C, IP67 ingress protection, IK10 impact rating, and TVS 4000V surge protection, the DS-2TD2137T-4/QY handles coastal, alpine, and heavy industrial environments.
- Sites Requiring Long-Term Low-Maintenance Monitoring: The 10-year detector guarantee and PoE or multi-voltage power support mean the camera can be installed at remote or hard-to-access positions and expected to operate reliably over extended periods.
Why Choose the DS-2TD2137T-4/QY
Where a standard IP bullet camera can only record what visible light reveals, the DS-2TD2137T-4/QY identifies heat signatures that indicate genuine risk, including smouldering materials before flames appear, overheating equipment, and unauthorised access in total darkness. The 384×288 thermal resolution paired with a NETD of 35 mK or less gives reliable thermal contrast in conditions where lesser sensors produce noisy, indistinct imagery. The combination of 21 temperature measurement rules, smoking detection algorithms, and 4 VCA rule types in a single unit reduces the need for separate fire detection and intrusion detection devices at a given site boundary. Its IK10-rated, IP67-sealed bullet housing and -40 to 65 degree C operating range allow deployment on exposed perimeter poles, rooftop parapets, and industrial facility walls without shelter structures. Available at Security Wholesalers, the DS-2TD2137T-4/QY is suited to projects where thermal detection and fire prevention compliance are primary requirements, not afterthoughts.
Buyer Decision Tips
Buyer Tip 1 – Lens and Coverage Area: The fixed 4.4 mm lens provides a 90 degree by 65.3 degree horizontal by vertical field of view, which suits wide-area coverage of a yard, stockpile, or entry zone at close to medium range. If your application requires narrower coverage of a specific corridor or longer-range detection well beyond 84 m for vehicles, a longer focal length thermal lens will be more appropriate. Confirm your detection distance and coverage width before finalising lens selection.
Buyer Tip 2 – Temperature Measurement vs. Fire Alarm Compliance: This camera provides temperature exception alarms and smoking detection to assist fire prevention monitoring, but it is not a certified fire alarm device under Australian Standards. Verify with your fire safety consultant whether this unit satisfies the specific compliance requirements of your installation or whether it is intended to supplement an existing certified system.

Ideal Use Cases
Waste and Recycling Facilities
Spontaneous combustion is a known hazard in material recovery and landfill operations. The 550 degree C upper temperature limit and smoking detection algorithm allow continuous monitoring of stockpiles and sorting areas, triggering alarms before fires establish.
Electrical Substation and Power Infrastructure
Transformer overheating and switchgear faults produce thermal signatures detectable well before failure. With 10 configurable area measurement zones and exception alarm outputs, the DS-2TD2137T-4/QY can be positioned to monitor critical equipment continuously.
Industrial Perimeter and Fence Line Monitoring
VCA intrusion and line crossing rules detect human movement to 28 m and vehicle movement to 84 m regardless of lighting conditions. This makes the camera effective for securing perimeter fence lines at night without supplementary lighting infrastructure.
Fuel and Chemical Storage Areas
In environments where visible-light illumination or IR floodlights are avoided due to ignition risk, thermal imaging provides continuous monitoring of tank farms, fuel bunds, and chemical storage zones without introducing any light source.
Construction Sites and Temporary Compounds
The wide 90 degree horizontal field of view and pole-mount compatibility allow a single DS-2TD2137T-4/QY unit to cover a large compound entry or materials laydown area, detecting both unauthorised access and heat-related risk from site equipment.
Timber Yards and Sawmills
Accumulated sawdust and timber offcuts are fire-prone. The smoking detection algorithm and configurable temperature exception alarms allow early detection of smouldering conditions across storage bays and processing areas, where conventional smoke detectors have limited reach.
Choosing the Right Model
- Choose this model if: Your application requires temperature exception alarms up to 550 degrees C, smoking detection, and thermal-based perimeter intrusion detection in a single outdoor bullet camera with a wide 90 degree field of view and confirmed IK10 and IP67 protection for harsh industrial environments.
- Choose a different model if: Your requirement is primarily for high-resolution visible-light identification of individuals or licence plates, where a standard HD optical bullet or turret camera will provide far greater detail than a 384×288 thermal sensor. Thermal imaging is not designed for identity verification or detailed object recognition.
- Choose a different model if: Your site requires coverage at ranges significantly beyond 84 m for vehicle detection or 28 m for personnel, as the 4.4 mm lens is optimised for wide-area mid-range coverage rather than long-range narrow detection. A longer focal length thermal option would be more appropriate for those distances.
FAQs
- Can the DS-2TD2137T-4/QY detect fires in complete darkness?
Yes. Thermal imaging detects heat radiation rather than reflected visible light, so the camera operates fully in zero-light conditions. It does not require IR illuminators, floodlights, or any external lighting to produce thermal imagery or trigger temperature exception alarms, making it effective for night-time industrial perimeter and fire prevention monitoring.
- What does the temperature measurement range of -20 degrees C to 550 degrees C mean in practice?
The camera can measure surface and ambient temperatures across this range using 21 configurable rules including 10 point measurements, 10 area measurements, and 1 line measurement. You define exception alarm thresholds at specific values within that range, so the system triggers alerts when temperatures at monitored points exceed or fall below the thresholds you set, without requiring manual review of live footage.
- What is the smoking detection algorithm and how does it differ from temperature alarms?
The smoking detection algorithm analyses thermal image patterns to identify smoke signatures as a separate event from temperature threshold alarms. This allows the camera to raise an alert when smoke is present even if the measured temperature at a specific point has not yet reached the configured exception level, providing an additional early warning layer for fire prevention.
- How far can the camera detect a person or vehicle using its VCA rules?
Based on the confirmed detection range data for this model, human classification is effective to 28 m and vehicle classification is effective to 84 m. These ranges apply to the VCA rule types including intrusion, line crossing, region entrance, and region exiting. Detection range will vary with target size, angle of approach, and ambient thermal contrast.
- Is the DS-2TD2137T-4/QY suitable for outdoor installation in Australian coastal or alpine environments?
The operating temperature range of -40 degrees C to 65 degrees C, IP67 ingress protection against dust and water, IK10-rated impact resistance, and TVS 4000V lightning protection make the camera suited to exposed outdoor environments including coastal installations with salt air and high humidity as well as alpine sites with extreme cold. Confirm your specific environmental conditions against these ratings before installation.
- Does the camera support local storage if the network connection is interrupted?
Yes. The DS-2TD2137T-4/QY supports local recording to a MicroSD/SDHC/SDXC card of up to 256 GB. It also supports Auto Network Replenishment (ANR), which buffers footage to the card during network outages and automatically uploads the missing footage to NAS or NVR storage once the connection is restored.
- What power supply options are supported and does it work with standard PoE switches?
The camera accepts 24 VAC plus or minus 25%, 12 VDC plus or minus 25%, and PoE via IEEE 802.3af Class 3 at a maximum consumption of 5.5 W. Standard 802.3af PoE switches and injectors are compatible, which simplifies installation where a single Cat5e or Cat6 cable can deliver both power and network connectivity. Supplied by Security Wholesalers, compatible Hikvision junction boxes and mounting brackets are also available to suit this bullet housing.
