Product Overview
For perimeter protection where visible light alone cannot reliably detect threats after dark or in challenging conditions, the DS-2TD2617-6/QA delivers a dual-lens bi-spectrum bullet camera combining a 160×120 thermal sensor with a 4MP optical module in a single outdoor housing. The thermal lens operates at 6.2mm with a 25.0°x18.7° field of view, while the 8mm optical lens provides 2688×1520 resolution with up to 40m IR range and 120dB WDR for usable visual detail across high-contrast scenes. Equipped with onboard VCA analytics supporting up to 8 rules across line crossing, intrusion, region entrance, and region exiting, the camera triggers both white light visual alarms and configurable audio alerts when a detection event occurs. Temperature measurement across 21 programmable rules adds a secondary monitoring layer suited to industrial sites and storage facilities. Rated IP66 with TVS 6000V lightning protection and an operating range of -40°C to 65°C, this camera is built for demanding outdoor deployment.
Key Capabilities
Dual-Lens Bi-Spectrum Detection
The thermal module detects heat signatures independent of lighting, while the 4MP optical module captures visual detail for verification. Together they provide detection capability that neither a standard IP camera nor a standalone thermal unit can match on a perimeter fence line or access road.
Thermal Analytics with Up to 8 VCA Rules
Supports line crossing, intrusion, region entrance, and region exiting detection across up to 8 configurable rules. These analytics run on the thermal image layer, reducing false triggers caused by lighting changes, shadows, or headlight glare that typically affect optical-only cameras in outdoor environments.
Active White Light and Audio Alarm
On detection, the camera can activate a white light strobe at up to 40m range and trigger an audio alarm from 2 preset or 6 importable voice alerts. This active deterrence response is configurable separately for VCA events and temperature exception events, giving site managers granular control over alarm behaviour.
Temperature Measurement Across 21 Rules
Measures surface temperatures from -20°C to 150°C with ±8°C accuracy across 10 point rules, 10 area rules, and 1 line rule. This makes the camera suitable for monitoring equipment surfaces, stored materials, or confined entry zones where thermal anomalies indicate a fire risk or equipment fault.
IP66 and TVS 6000V Surge Protection
The IP66 rating blocks water ingress from driving rain and dust exposure. TVS 6000V lightning and surge protection is critical for exposed perimeter installations on rooftops, fence posts, or open industrial yards where transient voltage events can destroy unprotected equipment. Operating temperature spans -40°C to 65°C.
PoE and Local Storage with ANR
Accepts 802.3af PoE or 12VDC power, simplifying installation where a single cable run is preferred. MicroSD storage up to 256GB enables local recording, and Auto Network Replenishment (ANR) fills recording gaps automatically when network connectivity is interrupted, protecting footage continuity on remote or unstable connections.
Best For
- Perimeter Fence Lines and Access Roads: The thermal sensor detects intruder heat signatures in complete darkness, fog, or smoke where IR illumination alone fails, with VCA rules triggering immediate alarm responses across up to 8 defined zones.
- Industrial Fire Risk Monitoring: Temperature measurement across 21 rules, spanning point, area, and line modes, allows continuous surface temperature monitoring of machinery, storage tanks, or electrical equipment with automated alerts when thresholds are exceeded.
- Exposed Outdoor Installations: IP66 rating, TVS 6000V lightning protection, and a -40°C to 65°C operating range make this camera suitable for mounting on rooftop brackets, perimeter poles, or open yard walls where weather and electrical surge exposure are ongoing risks.
- Sites Requiring Active Deterrence: The combination of white light strobe and configurable audio alarm output means the camera can respond to thermal intrusion detections without requiring a human operator to trigger a separate device.
Why Choose the DS-2TD2617-6/QA
The DS-2TD2617-6/QA is a purpose-built thermal perimeter camera, not a repurposed optical bullet with a thermal accessory. Its 160×120 VOx UFPA sensor with NETD below 40mK at 25°C provides sufficient thermal sensitivity to detect a person at distance in conditions where optical cameras produce no usable image. The addition of the 4MP optical channel with 40m IR range means operators receive both a thermal detection trigger and a visual stream for identity-level detail within the same unit. The built-in active deterrence, 2 alarm inputs, 2 alarm outputs, RS-485 interface, and analog BNC output give integrators a broad range of connection options for linking to existing site control systems. Local ANR recording and up to 256GB MicroSD storage reduce dependence on continuous network uptime. Available through Security Wholesalers, the DS-2TD2617-6/QA suits industrial, mining, utilities, and critical infrastructure sites where detection reliability in adverse conditions cannot be compromised.
Buyer Decision Tips
Thermal Resolution and Detection Range: The 160×120 thermal resolution with a 6.2mm lens and 25.0°x18.7° field of view is optimised for medium-range perimeter detection, not long-distance identification. At this resolution, the thermal image confirms presence and triggers analytics reliably, but the optical channel at 8mm and 40m IR range handles the visual verification role. If your primary requirement is detecting movement across a wide open area at long range, consider whether a longer focal length thermal lens would better suit the scene geometry before selecting this model.
Temperature Accuracy Expectations: The ±8°C temperature measurement accuracy is suitable for detecting significant thermal anomalies such as overheating equipment or fire ignition points, but is not appropriate for applications requiring precise medical or laboratory-grade temperature readings. If the site requirement is early fire detection or equipment surface monitoring rather than exact temperature measurement, the ±8°C tolerance is well within practical thresholds for those use cases.

Ideal Use Cases
Industrial Perimeter Fence Lines
The thermal sensor detects intruder body heat regardless of lighting conditions or visual obstructions such as vegetation or fog. VCA rules trigger white light and audio alarms automatically, making the DS-2TD2617-6/QA effective on unmanned perimeter segments where immediate automated response is required.
Warehouse and Storage Yard Monitoring
Temperature measurement across 10 point and 10 area rules allows continuous monitoring of stored goods or equipment for thermal anomalies. Coupled with intrusion detection on the thermal image, the camera provides both security and early fire risk monitoring within the same installation point.
Electrical Substation and Utilities Sites
The TVS 6000V surge protection and IP66 rating support deployment in electrically exposed environments. Temperature exception alarms can be configured against switchgear panels or cable runs to detect overheating before a fault escalates, providing an operational monitoring function alongside perimeter security.
Construction Site After-Hours Coverage
Construction sites lack reliable artificial lighting at night. The thermal channel detects intruder heat signatures in unlit areas, while the 40m IR-equipped optical channel provides the 4MP visual stream needed for incident documentation, and local MicroSD recording with ANR protects footage even when site network connectivity is intermittent.
Remote or Unmanned Facility Monitoring
ANR recording fills gaps in footage when network connectivity drops, and up to 256GB local MicroSD storage keeps recordings on-device. The PoE option reduces the infrastructure needed at remote mounting points, and the -40°C lower operating limit supports deployment in cold-climate outdoor locations without heated enclosures.
Choosing the Right Model
- Choose this model if: You need a single outdoor bullet unit that combines thermal intrusion detection with a 4MP optical channel, active deterrence alarms, and temperature exception monitoring for perimeter security or industrial fire risk applications at a site exposed to harsh weather and electrical surge risk.
- Choose a different model if: Your application requires long-range thermal detection beyond what a 160×120 sensor with a 6.2mm lens can practically deliver, or if precise temperature measurement to within ±1°C is required for laboratory or medical screening contexts – in those cases, a higher-resolution cooled thermal sensor or a purpose-built thermometry device would be more appropriate.
- Choose a different model if: The installation is indoors with no weather exposure and no requirement for thermal detection – a standard 4MP optical bullet or dome camera with IR will deliver comparable visual results at a lower cost point without the thermal sensor overhead.
FAQs
- What does the dual-lens design mean in practical terms for an outdoor perimeter installation?
The DS-2TD2617-6/QA houses 2 independent imaging modules in one bullet enclosure. The thermal lens detects heat signatures for reliable intrusion detection regardless of lighting, while the 8mm optical lens with 40m IR range captures the 4MP visual image used for post-event review and incident documentation. Both streams are available simultaneously without the need for 2 separate camera positions.
- How accurate is the temperature measurement, and is it suitable for fire detection?
The camera measures surface temperatures from -20°C to 150°C with ±8°C accuracy across 21 configurable rules. This level of accuracy is appropriate for detecting overheating equipment, stored material ignition risks, and early-stage fire events where a surface temperature rise of tens of degrees is the threshold of concern. It is not designed for precision thermometry applications requiring sub-degree accuracy.
- Can the alarm output connect to an existing site security system or access control panel?
Yes. The camera provides 2 dedicated alarm outputs with configurable alarm response actions including relay output, recording, FTP upload, and email linkage. An RS-485 interface is also available for integration with compatible third-party control devices. The 2 alarm inputs allow external trigger signals to be fed into the camera from perimeter sensors or other detection devices.
- What VCA rules does the thermal analytics engine support, and how many can run simultaneously?
The thermal VCA engine supports 4 rule types: line crossing, intrusion, region entrance, and region exiting. Up to 8 individual rules can be active simultaneously, allowing multiple zones or crossing lines to be monitored across a wide field in a single camera view without requiring separate cameras for each detection boundary.
- Does the DS-2TD2617-6/QA support local recording if the network goes down?
Yes. The camera supports MicroSD cards up to 256GB for on-device local recording. Auto Network Replenishment (ANR) automatically uploads locally buffered footage to the NVR once network connectivity is restored, preventing recording gaps from appearing in the archived stream. NAS recording via NFS or SMB/CIFS is also supported when a network storage device is available.
- Is the camera suitable for mounting in locations exposed to lightning or electrical surge events?
The DS-2TD2617-6/QA includes TVS 6000V lightning, surge, and voltage transient protection built into the housing. Combined with the IP66 weatherproof rating and an operating temperature range of -40°C to 65°C, the camera is designed for exposed outdoor mounting positions including rooftop brackets, perimeter poles, and open yard walls where transient voltage risk is present.
- Where can I source the DS-2TD2617-6/QA in Australia, and what should I know about availability?
The DS-2TD2617-6/QA is part of the Security Wholesalers range. As noted on the product listing, this model carries a 4-6 week lead time and is not held as regular stock, so it is advisable to plan procurement well in advance of installation deadlines, particularly for staged site rollouts where camera deliveries need to align with mounting and cabling completion schedules.
