Key Capabilities
Thermographic Temperature Measurement
The thermal channel measures temperatures from -20°C to 550°C with accuracy of ±2°C or ±2%, supporting point, area and line rules across 273 configurable presets. This makes it directly applicable to process monitoring, equipment supervision and heat anomaly detection in industrial environments.
Dynamic Fire Detection
The DS-2TD4167T-25/W supports dynamic fire detection across up to 10 simultaneous fire points, with a detection range of up to 1470m for a 2x2m object. This level of early detection is relevant for fuel storage zones, material handling areas, conveyor systems and high-risk manufacturing sites.
40x Optical Zoom Verification
The optical channel’s 6-240mm motorised lens provides 40x optical zoom, allowing operators to move from a wide field of view to close inspection of distant targets, perimeter activity or thermal events. DORI ranges extend to vehicle recognition at 564m and vehicle detection at 2255m.
Deep Learning Perimeter Protection
Line crossing, intrusion, region entrance and region exit detection are all supported using deep learning analytics. Up to 10 VCA scenes with 8 rules per scene can be configured, giving operators flexible coverage of fence lines, restricted zones, gates and critical infrastructure boundaries.
Smart Tracking and PTZ Control
Panorama tracking, event tracking and multi-scene patrol tracking are supported alongside 300 preset positions, 8 patrols with up to 32 presets per patrol, and 360-degree continuous pan with -20° to +90° tilt. This gives operators automated PTZ workflows across large or complex monitored sites.

Choosing the Right Model
- Choose this model if: Your site requires thermographic temperature monitoring, fire detection, and long-range optical PTZ verification from a single device. The 25mm thermal lens, 640 x 512 thermal resolution and 40x optical zoom are suited to focused industrial monitoring where both heat detection and visual confirmation are operationally required.
- Choose a different model if: Your application only needs standard perimeter security without thermal or thermographic functions. A PTZ camera without a thermal channel will typically cost significantly less and may be more appropriate for video-only perimeter monitoring where temperature measurement and fire detection are not required.
- Choose a different model if: You need a wider thermal field of view for broad area scanning rather than focused detection. A shorter focal length thermal lens provides a wider field of view that may be better suited to open-area thermal screening rather than targeted long-range measurement.
FAQs
- What type of sites is the DS-2TD4167T-25/W designed for?
This camera is designed for industrial and critical infrastructure sites that require thermographic monitoring combined with optical PTZ surveillance. Confirmed applications include factories, electrical substations, hydropower stations, fuel and chemical storage facilities, industrial perimeters, logistics yards and any high-risk environment where temperature exception detection and fire indication are operationally important alongside visual security monitoring.
- What is the difference between the thermal channel and the optical channel on this camera?
The thermal channel uses a 640 x 512 vanadium oxide uncooled focal plane array to detect heat signatures, measure temperatures from -20°C to 550°C and identify fire points. The optical channel provides 4MP video with 40x optical zoom and 120dB WDR for visual identification and incident verification. Both channels operate simultaneously, with picture-in-picture display of partial thermal imagery over the optical view supported.
- What is the fire detection range of the DS-2TD4167T-25/W?
Fire detection range depends on target size. For a 2x2m object the confirmed detection range is 1470m, and for a 1x1m object it is 735m. Dynamic fire detection covers up to 10 simultaneous fire points. These figures should be matched against your actual target size and deployment distance before specifying this camera for a fire prevention role.
- How does the temperature measurement function work?
The camera supports 3 rule types including point, area and line measurement rules. Up to 273 presets can be configured as measurement scenes, with 21 rules per scene covering 10 points, 10 areas and 1 line. Temperature measurement covers -20°C to 550°C with maximum accuracy of ±2°C or ±2%. Alarms can be triggered when temperature exceptions exceed configured thresholds.
- Does this camera require specialised power supply or cabling for installation?
The DS-2TD4167T-25/W supports 24V AC, 36V DC, 48V DC and Hi-PoE power inputs with a maximum consumption of 65W. Standard PoE switches will not supply sufficient power for this camera. Confirm the power source, cable run distances, voltage drop calculations and whether a dedicated Hi-PoE switch or local power supply is required before finalising the installation design.
- What perimeter protection analytics are included, and how many rules can be configured?
The camera supports line crossing, intrusion, region entrance and region exit detection using deep learning. Up to 10 VCA scenes can be configured, with 8 VCA rules per scene. This allows operators to create layered detection coverage across multiple zones, fence lines, gates and restricted areas within a single camera installation.
- Are there export control considerations for purchasing a thermal camera?
Thermal imaging cameras including the DS-2TD4167T-25/W may be subject to export control regulations in Australia and internationally.
