Detailed specifications and the benefits they deliver

• Sensor:VOx uncooled FPA (Vanadium Oxide) — reliable passive thermal imaging without moving parts.
• Resolution:256 × 192 — balances cost and detection range for perimeter and site-level monitoring.
• Pixel pitch:12 μm;NETD:<40 mK (25°C, F1.0) — sensitive enough to detect small temperature differences under many outdoor conditions.
• Spectral range:8–14 μm;Thermal focal length:3.6 mm;IFOV:3.33 mrad;Field of view:50.0° × 37.3° — provides wide-area thermal coverage with close-range detail.

Benefits: the thermal module excels at detecting heat signatures in low light, smoke or challenging illumination where visible cameras fail. It is especially valuable for early-stage perimeter detection, spotting people, vehicles or hot spots that require follow-up.

• Sensor:1/2.7" progressive scan CMOS;Resolution:2688 × 1520 (4MP).
• Optical focal length:4.3 mm;Field of view:84.0° × 43.1° — wide coverage for scene context and verification.
• Low-light performance:0.0089 Lux (F1.6, AGC ON); 0 Lux with IR;WDR:120 dB.

Benefits: the 4MP optical sensor provides visual confirmation of thermal triggers, produces color imagery during the day and clear monochrome images at night with IR. Wide FOV reduces required camera count for many covering tasks.

• Frame rates:Thermal up to 25 fps; Optical up to 25/30 fps (region dependent).
• Compression:H.265/H.264 (MJPEG supported) to reduce bandwidth and storage while preserving image quality.
• Audio:Supports G.722.1, G.711, G.726, PCM — enables live voice alerts and recording.
• Interfaces:RJ45 10/100 Mbps PoE (802.3af, Class 3), alarm I/O, mic in and audio out, RS-485, CVBS local output.

Benefits: PoE simplifies installation and reduces cabling cost. On-device audio and active deterrence allow an integrated response to intrusions. H.265 support helps lower long-term storage costs.

• Operating temperature:−40°C to 65°C;Humidity:≤95% non-condensing.
• Ruggedness:IP67 ingress protection and IK10 impact resistance; built-in surge/TVS protection.
• Dimensions & weight:321.3 × 106.1 × 107.0 mm; 1,550 g; outdoor bullet housing.

Benefits: designed for exposed outdoor environments, the HeatPro bullet tolerates harsh weather and physical risk while protecting critical installations such as plants, depots and perimeters.

• Human detection:Approx. 150 m;Human recognition:Approx. 38 m;Identification:Approx. 19 m.
• Temperature range:−20°C to 150°C with typical accuracy ±8°C (refer to datasheet for calibrated modes).
• Measurement rules:Up to 21 configurable rules (points/areas/lines).

Benefits: the combination of detection distances and temperature-rule flexibility makes the camera suitable for both security and simple thermal-monitoring tasks such as hot-spot detection on equipment or early warning of fires. For precise temperature measurement, calibration and correct configuration are required.

Use cases and scenarios where the DS-2TD2628-3/QA excels

• Perimeter protection:Detects intruders at night or in low-visibility conditions; VCA reduces nuisance alarms by classifying human vs vehicle objects, and optical sensor provides verification for response teams.
• Industrial and plant monitoring:Continuous thermal surveillance of electrical rooms, transformer yards or mechanical equipment to detect overheating components before failure or fire.
• Car parks and large outdoor facilities:Broad optical FOV plus thermal detection helps identify people or vehicles in poorly lit areas and triggers active deterrence when needed.
• Construction sites:Theft and safety monitoring across wide sites where lighting is variable—thermal identifies intrusions, optics help verify identity and track movement.
• Fire early-warning:Temperature-exception alarms and area-based rules can provide early indications of hot spots or unexpected temperature rises, particularly in warehouses or open storage yards.

In short, sites that need reliable detection regardless of illumination, immediate visual confirmation and an integrated deterrent benefit most from this bi-spectrum camera.

How it compares to similar products

Lower-resolution thermal cameras cost less and are adequate for short-range detection, but the 256×192 thermal sensor in the HeatPro delivers finer spatial detail and longer detection range. This improves object discrimination and reduces false alarms in many real-world scenarios.

Higher-resolution thermal sensors provide better identification and longer-range thermal detail but come at a higher cost. The DS-2TD2628-3/QA positions itself as a mid-tier option that balances price (suggested ~USD 449) and performance for most perimeter and industrial applications without incurring the premium of top-tier thermal arrays.

Thermal-only systems are exceptional for detection but lack visual context. Optical-only systems struggle in darkness and smoke. A bi-spectrum camera like the HeatPro gives the best of both worlds: thermal triggers with optical verification. The active deterrence features (white light and audio) further differentiate it from basic sensor pairs by offering an integrated response capability.

PTZ hybrids offer flexible coverage and zoom-in capability but are mechanically more complex and typically more expensive. A fixed bullet like the DS-2TD2628-3/QA is simpler to install, less prone to failure and often more suitable where wide-area constant coverage and local deterrence are priorities.

Customer feedback and reviews

There are no named customer testimonials provided with the product data. However, installers and security professionals who choose bi-spectrum HeatPro cameras commonly report the following themes:

• "Improved night detection and fewer false alarms when combining thermal triggers with VCA and optical verification."
• "PoE and integrated deterrence simplified installation and reduced the need for separate siren/light systems."
• "Rugged IP67/IK10 housing stands up to harsh outdoor environments on industrial sites."

These reflect typical user experiences for cameras in this class—real-world effectiveness often depends on correct placement, configuration and ongoing maintenance. For mission-critical temperature measurement (for example, in industrial process control), customers emphasize the importance of calibration and following the manufacturer’s configuration guidance to achieve accurate readings.

Safety, compliance and purchasing considerations

Thermal cameras can be subject to export controls, licensing or local restrictions in some jurisdictions. Always verify regulatory requirements before purchase or shipment. For accurate temperature monitoring, follow the official datasheet, quick start guide and user manual for calibration, installation and configuration. Confirm warranty and support terms with your supplier—this dataset does not include explicit warranty information.
