Product Overview
Critical infrastructure sites such as airports, power stations, prisons, and chemical plants demand detection technology that works in complete darkness and in conditions where visible cameras offer little warning. The DS-2TD4237-10/V2 is a bi-spectrum PTZ speed dome combining a 384×288 thermal module with a 10mm fixed thermal lens and a 1080p optical module with 100m IR, mounted in a single rotating housing capable of 360° continuous pan coverage. Equipped with a built-in GPU, it runs deep learning VCA functions including line crossing, intrusion, and region entrance and exit detection directly on-device, while simultaneously running dynamic fire point detection across up to 10 fire points and temperature anomaly monitoring across a range of -20°C to 150°C. It is well suited to perimeter defence deployments and fire prevention monitoring at large industrial facilities, recycling centres, gas stations, and large warehouses. Please note this is a special order item with a lead time of 4 to 6 weeks.
Key Capabilities
Thermal Detection at the Perimeter
The 384×288 vanadium oxide uncooled focal plane array sensor with a 17μm pixel interval and NETD below 40mK detects heat signatures through darkness, smoke, and low-visibility conditions where visible cameras cannot, making it suited to unlit perimeters and outdoor fence lines.
Dynamic Fire Point Detection
The thermal module runs an advanced fire detection algorithm capable of identifying up to 10 simultaneous fire points dynamically. This makes the DS-2TD4237-10/V2 directly applicable to fire prevention monitoring at recycling centres, gas stations, large warehouses, and chemical plants where early detection is critical.
Deep Learning Behaviour Analysis
A built-in GPU powers on-device VCA with up to 8 configurable rules across 4 rule types: line crossing, intrusion, region entrance, and region exiting. This allows precise perimeter zone logic without relying on server-side processing, reducing latency in alarm response.
360° PTZ Coverage with Patrol Scanning
Continuous 360° pan with tilt from -5° to +90° and up to 300 programmable presets enables flexible coverage of large sites. 8 patrol scan paths with up to 32 presets each, 4 pattern scans, and multiple park behaviours allow fully automated surveillance sweeps across wide perimeter zones.
Temperature Anomaly Monitoring
Supports 21 temperature measurement rules across 10 point measurements, 10 region measurements, and 1 line measurement, with a measurement range of -20°C to 150°C. Temperature anomaly alarms can trigger recording, FTP upload, relay output, or email notification automatically.
Industrial-Grade Environmental Protection
Rated IP66 for dust and water ingress protection, with TVS 6000V lightning, surge, and voltage transient protection. Operating range of -30°C to 60°C means the unit continues functioning in both extreme cold and high-heat industrial environments without additional enclosures.
Best For
- Critical Infrastructure Perimeters: Airports, power stations, and prisons where the thermal module and deep learning VCA detect unauthorised intrusions in complete darkness with up to 8 configurable zone rules.
- Fire Prevention at High-Risk Sites: Recycling centres, gas stations, and chemical plants where the dynamic fire point detection algorithm can identify up to 10 simultaneous thermal fire signatures and trigger immediate alarm actions.
- Large Construction Sites and Farms: Wide outdoor areas requiring patrol scanning across multiple preset positions, with thermal detection covering approaches that are unlit or partially obscured by dust or low visibility.
- Temperature Anomaly Monitoring: Industrial processes or storage areas where tracking heat anomalies across points, regions, and lines within the -20°C to 150°C measurement range provides an early-warning trigger before a situation escalates.
- National Parks and Remote Outdoor Sites: Locations subject to extreme temperatures (-30°C to 60°C operating range) where lightning protection rated to TVS 6000V and IP66 ingress protection are required for year-round unattended operation.
Why Choose the DS-2TD4237-10/V2
The DS-2TD4237-10/V2 addresses two of the most demanding detection requirements in a single housing: perimeter intrusion and fire prevention. Unlike a standard PTZ that relies entirely on visible light, this unit pairs a 384×288 thermal channel with the optical 1080p channel, so detections occur in conditions where no IR illuminator or visible light source exists. The built-in GPU enables deep learning VCA to run locally across all 8 configured rules without server dependency, and the fire detection algorithm runs concurrently rather than as a separate mode. The 10mm thermal lens delivers a 37.7° x 28.7° field of view suited to mid-range perimeter coverage, while the optical channel provides up to 100m IR reach for visual verification of thermal alerts. With TVS 6000V surge protection and operation down to -30°C, this camera is engineered for genuinely hostile outdoor environments. Available through Security Wholesalers, it is a specialist instrument designed for sites where standard IP cameras cannot provide sufficient detection certainty.
Buyer Tip – Power Requirements: The DS-2TD4237-10/V2 requires 24V AC (±25%) at up to 30W. This is not a PoE camera. Plan for a dedicated 24V AC power supply at the installation point. Long cable runs from a power source must account for voltage drop, particularly in cold environments where heater draw may be factored into total consumption by the installer.
Buyer Tip – Lead Time and Project Planning: This is a special order item with a lead time of 4 to 6 weeks. It should be specified and ordered well ahead of installation milestones. Confirm lens variant selection (this listing covers the 10mm thermal lens) against site survey requirements before ordering, as the 10mm lens produces a 37.7° x 28.7° thermal field of view suited to mid-range perimeter widths.

Ideal Use Cases
Airport and Port Perimeters
The 360° continuous pan, 300 presets, and up to 8 VCA zone rules allow perimeter coverage across wide runway boundaries or wharf fence lines, with thermal detection triggering intrusion alarms independent of lighting conditions or time of day.
Recycling Centres and Waste Facilities
Stockpile fires in recycling and waste environments can develop slowly before becoming visible. The fire detection algorithm tracking up to 10 thermal fire points provides early identification of hot spots, enabling alarm actions before a fire escalates to a serious event.
Power Stations and Substations
Temperature anomaly monitoring across 21 measurement rules can track heat signatures across electrical infrastructure. Combined with deep learning intrusion detection, this unit provides both fire-risk monitoring and perimeter access control at a single installation point.
Large Warehouses and Chemical Plants
The DS-2TD4237-10/V2 can be mounted at height to monitor open floor areas or outdoor storage with thermal oversight. Fire detection and temperature alarms integrate with relay outputs and FTP/email linkage for direct connection to existing site management systems.
Prisons and Secure Facilities
Perimeter fence line monitoring with line crossing and region entrance VCA, supported by thermal detection that cannot be defeated by low light, clothing colour, or camouflage, makes this unit applicable to high-security custody and detention perimeter applications.
Construction Sites and National Parks
Sites with no fixed lighting across large open areas rely on thermal for reliable nighttime detection. Patrol scanning across up to 8 paths with 32 presets each allows the unit to sweep the full site automatically, with power-off memory ensuring preset positions are retained after any supply interruption.
Choosing the Right Model
- Choose this model if: Your site requires simultaneous perimeter intrusion detection and fire or temperature anomaly monitoring in a single PTZ housing, particularly where visible light is absent or unreliable and where 24V AC power infrastructure can be provided at the camera location.
- Choose a different model if: You need PoE-powered deployment, as this unit requires 24V AC at up to 30W and is not compatible with standard PoE switches. A fixed thermal camera may also be more appropriate for static single-zone monitoring where PTZ movement and patrol scanning are not required, as it would reduce installation complexity and cost at smaller sites.
- Consider the lens carefully: This listing covers the 10mm thermal lens variant, which produces a 37.7° x 28.7° thermal field of view. If your site survey requires a narrower or wider thermal coverage angle, confirm the correct focal length variant is selected before ordering, as this is a special order item with a 4 to 6 week lead time.
FAQs
- What does the 10mm designation refer to on the DS-2TD4237-10/V2?
The 10mm refers to the focal length of the thermal module lens, not the optical channel. This produces a thermal field of view of 37.7° x 28.7°, suited to mid-range perimeter coverage. The optical module uses a motorised zoom lens with a field of view ranging from 65.6° wide to 2.46° telephoto, independent of the thermal lens specification.
- Can this camera detect fires in complete darkness?
Yes. The thermal module operates on heat signature detection across an 8μm to 14μm waveband and does not require any visible light or IR illumination to detect fire points. The fire detection algorithm can track up to 10 dynamic fire points simultaneously and trigger alarm actions including relay output, email, FTP upload, and SD card recording independently of the optical channel.
- How accurate is the temperature measurement function?
The temperature measurement function has a confirmed accuracy of ±8°C across a range of -20°C to 150°C. This is typical of uncooled microbolometer thermal cameras used for pre-alarm temperature monitoring. It is suited to detecting relative temperature anomalies and trend-based alarms rather than precision laboratory-grade temperature measurement.
- Does this camera require PoE or a special power supply?
This unit requires 24V AC (±25%) at a maximum consumption of 30W. It is not compatible with PoE switches or injectors. A dedicated 24V AC power supply must be installed at or near the camera location. Installers should account for voltage drop over cable runs and ensure the power supply is rated for the full 30W load.
- How does the PTZ patrol scanning work across a large perimeter?
Up to 8 patrol scan paths can be programmed, each containing up to 32 preset positions. The camera cycles through assigned presets in sequence, pausing at each for a configured dwell time. In addition, 4 pattern scans of over 10 minutes each can be recorded, and a full range of park behaviours including panorama scan, frame scan, tilt scan, and random scan allow unattended perimeter sweeping without operator input.
- Can the thermal and optical streams be viewed simultaneously?
Yes. The DS-2TD4237-10/V2 provides both a thermal stream and an optical visible light stream as independent channels. Both can be viewed simultaneously through the iVMS-4200 client or a compatible NVR. The main stream supports thermal output at up to 25fps in multiple resolutions alongside the 1080p optical stream at 25fps (50Hz) or 30fps (60Hz).
- What integration options are available for connecting this camera to existing site management platforms?
The unit supports ISAPI, Hikvision SDK, ONVIF (Profile S, Profile G, Profile T), and an open-ended API for third-party management platform integration. Alarm inputs support up to 7 channels (0-5V DC) and 2 relay outputs, enabling direct connection to existing access control or alarm management infrastructure. RS485 is also available with PELCO-P and PELCO-D self-adaptive protocol support.
- Is this camera available for immediate dispatch or is there a lead time?
The DS-2TD4237-10/V2 is a special order item. The confirmed lead time is 4 to 6 weeks from order placement. Project timelines should be planned accordingly. For procurement and ordering enquiries, Security Wholesalers can assist with confirmation of availability and lead time at the time of order.
