Product Overview
Built for sites where visible heat signatures matter more than reflected light, the DS-2TD2136T-10 is a thermographic bullet camera that detects threats and temperature anomalies in complete darkness, heavy smoke, fog, and dust. Using a Vanadium Oxide uncooled focal plane array with a 17 μm pixel pitch and NETD below 40mK, it captures genuine thermal contrast at 384 × 288 resolution through a 10mm lens with a 37.20° × 28.33° field of view. Featuring Adaptive AGC, DDE, and 3D DNR image processing, it delivers consistent thermal imagery across varying environmental conditions. It also includes a dynamic fire detection engine capable of identifying up to 10 simultaneous fire points, along with a temperature measurement range spanning -20°C to 550°C across up to 21 configurable rules. This makes it well suited to critical infrastructure monitoring, industrial sites, substations, and perimeter protection scenarios where conventional optical cameras cannot reliably operate.
Key Capabilities
384 × 288 Thermal Sensor at 17 μm Pixel Pitch
The Vanadium Oxide uncooled focal plane array with 17 μm pixel pitch and NETD below 40mK captures fine thermal detail at close-to-mid range. This level of sensitivity distinguishes warm targets from background clutter even in minimal temperature differential conditions.
Dynamic Fire Point Detection
The DS-2TD2136T-10 uses an advanced fire detection algorithm to identify up to 10 simultaneous fire points within the scene. This is suited to waste storage yards, electrical substations, industrial plant rooms, and outdoor material stockpiles where early ignition detection is operationally critical.
Temperature Measurement Across 21 Rules
Operators can configure up to 21 temperature measurement rules covering 10 individual points, 10 regions, and 1 line. The camera measures temperatures from -20°C to 550°C with accuracy within ±2°C or ±2%, enabling automated alerts when thresholds are breached.
Perimeter VCA with Up to 8 Rules
Four VCA rule types – line crossing, intrusion, region entrance, and region exiting – can be configured across up to 8 simultaneous rules. Thermal-based detection is unaffected by lighting changes, shadows, or camouflage, reducing spurious triggers common with optical analytics.
IP66 Rated with TVS 6000V Lightning Protection
The bullet housing carries IP66 ingress protection for permanent outdoor installation. TVS 6000V surge and lightning protection is confirmed, which is important for rooftop, fence-line, and open-yard deployments where electrical transients are a real risk.
De-icing Heater and Wide Operating Range
Rated for operation from -40°C to 65°C, the camera includes a de-icing heater that activates in freezing conditions. This protects the optics and housing in cold-climate environments such as refrigerated facilities, alpine sites, and exposed coastal installations.
Best For
- Perimeter Detection in Zero-Light Conditions: Thermal imaging requires no ambient light or IR illumination to detect intruders, making this camera effective across unlit fence lines, yards, and approach routes where optical cameras and even IR cameras are limited.
- Fire and Hotspot Monitoring: The confirmed fire detection algorithm and wide temperature measurement range suit sites with combustible materials, electrical switchboards, or industrial processes where hotspot development must be caught before escalation.
- Sites with Smoke, Dust, or Fog Interference: The 8 μm to 14 μm long-wave thermal response penetrates environmental obscurants that block optical cameras, maintaining situational awareness in quarries, foundries, and waste processing facilities.
- Critical Infrastructure with Integration Requirements: Open-ended API support for ISAPI and Hikvision SDK, along with 2-channel alarm inputs and outputs, suits integration into existing security management platforms and PLC-based industrial automation systems.
Why Choose the DS-2TD2136T-10
The DS-2TD2136T-10 occupies a specific position in thermal surveillance: a fixed-lens, network-connected thermographic bullet with both VCA analytics and active temperature measurement built into the same device. Where a standard optical bullet camera with IR requires some ambient illumination and is defeated by smoke or fog, this camera detects heat signatures at distances suited to the 10mm lens regardless of lighting or environmental obscurants. The combination of up to 8 concurrent VCA rules and 21 temperature measurement rules in a single unit removes the need for a separate dedicated fire detection sensor in many medium-range scenarios. IP66 protection, TVS 6000V surge immunity, a de-icing heater, and operation down to -40°C make it a genuine all-weather outdoor deployment option. Available at Security Wholesalers, the DS-2TD2136T-10 is an important product for industrial security designers and integrators specifying systems where standard cameras cannot meet the detection requirements.
Buyer Tip: The DS-2TD2136T-10 uses a fixed 10mm lens with a 37.20° × 28.33° field of view and a minimum focusing distance of 1m. Before ordering, calculate the detection and recognition ranges required at your site using the MRAD value of 1.70. If you need wider coverage or longer detection distances, confirm whether a shorter or longer focal length variant is appropriate for your scenario. Note that there may be a 4-7 week lead time on this product, so factor this into project timelines accordingly.
Buyer Tip: The camera supports PoE (802.3at, Class 4), 24VAC, and 12VDC power inputs. When the de-icing heater is active, maximum power draw rises from 8W to 20W. If powering via PoE, confirm that your switch or injector supports Class 4 at the required power budget, particularly if heater activation is expected in your operating environment.

Ideal Use Cases
Electrical Substations and Switchboard Rooms
The temperature measurement capability with 21 configurable rules allows continuous monitoring of switchgear, transformers, and busbars. Alerts trigger when component temperatures breach defined thresholds, enabling condition monitoring well before a fault becomes a fire.
Waste Processing and Recycling Facilities
Combustible material stockpiles are a known fire risk at waste and recycling sites. The DS-2TD2136T-10 detects up to 10 simultaneous fire points dynamically, and its thermal imaging operates through dust and smoke that would obscure standard optical cameras.
Unlit Industrial Perimeters and Fence Lines
VCA rules for line crossing and intrusion function from the camera’s thermal sensor, which requires no light source whatsoever. Fence lines and perimeters at remote industrial sites can be monitored continuously without any lighting infrastructure.
Ports, Terminals, and Logistics Yards
Large open yards with heavy vehicle movement and variable lighting are difficult environments for optical cameras. Thermal imaging cuts through exhaust fumes, dust, and night conditions, with VCA rules providing perimeter alerts across container storage and loading zones.
Cold-Climate or Exposed Coastal Installations
With confirmed operation from -40°C and a de-icing heater that activates in freezing conditions, the DS-2TD2136T-10 suits alpine facilities, cold storage sites, and coastal infrastructure where temperature extremes would cause failures in standard camera housings.
Choosing the Right Model
- Choose this model if: Your site requires fire point detection, temperature anomaly alerts, or perimeter VCA in conditions where optical cameras cannot reliably operate – such as complete darkness, smoke, dust, fog, or extreme temperature environments.
- Choose a different model if: Your primary requirement is facial recognition, licence plate capture, or identifying fine visual detail in persons or vehicles. Thermal cameras detect heat, not optical detail, and the 384 × 288 resolution of this model is not suited to identification tasks that require high-resolution optical imagery.
- Choose a different model if: You need pan, tilt, or zoom capability for wide-area scanning or operator-directed tracking. This is a fixed-lens bullet and cannot be redirected once mounted without physically adjusting the bracket.
- Choose a different model if: Your monitoring distance or required detection range does not match the 10mm lens field of view. A different focal length may be required depending on your specific MRAD-based detection or recognition distance calculations.
FAQs
- What does the DS-2TD2136T-10 actually detect, and how is it different from a standard IR bullet camera?
This camera detects heat emitted by objects and people rather than reflected visible light. Where a standard IR bullet camera needs its own infrared illumination to see in the dark, the DS-2TD2136T-10 passively detects thermal radiation in the 8 μm to 14 μm waveband. This means it operates in complete darkness, and its detection is unaffected by smoke, dust, heavy rain, or fog that would significantly degrade an optical camera’s image.
- Can this camera measure the temperature of specific objects or zones in the scene?
Yes. The camera supports up to 21 temperature measurement rules across 3 types: 10 individual measurement points, 10 configurable regions, and 1 line measurement. Each rule can be set with high and low temperature thresholds. When a threshold is breached, the camera triggers a configurable alarm action including relay output, FTP upload, email linkage, or SD card recording. The measurement range is -20°C to 550°C with accuracy of max ±2°C or ±2%.
- How does the fire detection function work on the DS-2TD2136T-10?
The camera uses a dynamic fire point detection algorithm that monitors the thermal scene for signatures consistent with active ignition. It can identify up to 10 simultaneous fire points within the field of view and trigger alarm outputs in response. This is distinct from temperature measurement alerts: fire detection responds to the thermal signature pattern of combustion rather than a threshold applied to a defined measurement zone.
- What perimeter analytics rules does this camera support?
The camera supports 4 VCA rule types: line crossing, intrusion, region entrance, and region exiting. Up to 8 VCA rules can be active simultaneously. Because these analytics operate from the thermal image, they are not affected by changes in ambient lighting, shadows, or headlights – sources of false triggers that commonly affect optical-based VCA in outdoor environments.
- What are the power requirements, and will standard PoE switches work with this camera?
The DS-2TD2136T-10 supports PoE 802.3at Class 4, 24VAC ±25%, and 12VDC ±20%. In normal operation it draws a maximum of 8W. When the de-icing heater activates, consumption rises to a maximum of 20W. For PoE deployments, your switch or injector must support 802.3at (PoE+) rather than standard 802.3af, and must budget for 20W per port if heater activation is expected at the installation location.
- Can the DS-2TD2136T-10 be integrated with third-party VMS or industrial platforms?
Yes. The camera provides an open-ended API with ISAPI support and Hikvision SDK compatibility, and is confirmed to work with third-party management platforms. It also provides 2-channel alarm inputs and 2-channel relay outputs for direct hardware integration with access control panels, industrial PLCs, or building management systems. iVMS-4200 is the confirmed native client.
- Is there any lead time I should plan around when ordering this camera?
Yes. There may be a 4-7 week lead time on the DS-2TD2136T-10 due to the specialised nature of thermographic hardware. If you are specifying this camera for a project with a fixed installation date, factor this lead time into your procurement schedule.
