Hikvision DS-2TD2628-3/QA HeatPro Bi-Spectrum Bullet Camera

This premium bi-spectrum bullet camera is designed for security systems that require both visual surveillance and precise temperature alerts. The thermal sensor features a 256 × 192 resolution with a 12 μm pixel pitch and a thermal sensitivity (NETD) of ≤ 40 mK. This high sensitivity allows the camera to detect minute temperature differences and spot anomalies early, which is essential for fire prevention and critical infrastructure security. The 3.6mm fixed thermal lens delivers a wide 50.0° × 37.2° field of view, providing broad coverage for short-to-medium range monitoring scenarios.

The optical module boasts a 1/2.7" Progressive Scan CMOS sensor delivering a 4MP (2688 × 1520) resolution, accompanied by a 4 mm lens. The bi-spectrum feature allows the system to overlay thermal and optical images (bi-spectrum image fusion), providing security personnel with a highly detailed composite view that facilitates faster object recognition and decision-making.

Advanced Bi-Spectrum Image Fusion

Unlike standard thermal cameras, the DS-2TD2628-3/QA features advanced bi-spectrum image fusion technology. This blends the visual details of the 4MP optical sensor with the thermal heat map from the VOx detector. The fused image allows operators to identify outlines, text, and specific objects much faster, removing the ambiguity of standard thermal-only feeds.

Note: This model supports temperature measurements ranging from -20°C to 150°C (-4°F to 302°F) with an accuracy of ±8°C. It is optimized for wide-area perimeter security, fire point detection, and smoking detection at short-to-medium range.

AI-Powered Perimeter Protection

Integrated deep-learning algorithms classify moving targets into human and vehicle categories. This advanced classification filters out false alarms from leaves, animals, rain, and light changes, ensuring that security alerts are highly accurate and actionable. It supports line crossing, intrusion detection, and region entrance/exit rules.

Early Fire & Smoking Detection

The DS-2TD2628-3/QA features dedicated fire and smoking detection algorithms. By analyzing temperature rises and specific flame shapes, the camera can detect fires in their earliest stages, generating rapid alerts before visible smoke or flames reach traditional fire sensors.

Rugged IP67 and IK10 Vandal-Resistant Build

Housed in a robust IP67 weather-resistant and IK10 vandal-resistant enclosure, the camera is designed to withstand extreme outdoor conditions, including heavy rain, dust, freezing temperatures, and physical tampering. Its bullet form factor allows for flexible wall or pole mounting in demanding environments.

Secure Communication and Edge Recording

The camera supports advanced network encryption including HTTPS, SSL/TLS, and 802.1X. It features a built-in MicroSD slot supporting up to 256 GB cards for local backup recording during network dropouts, ensuring no security footage or thermal data is lost.

TECHNICAL SPECIFICATIONS

FREQUENTLY ASKED QUESTIONS (FAQs)

What is a bi-spectrum camera?

A bi-spectrum camera integrates both a thermal sensor and a traditional optical visual sensor within the same housing. It allows operators to view the thermal image, the optical image, or a fused composite overlay of both streams simultaneously.

How does early fire detection work on this model?

The DS-2TD2628-3/QA utilizes specialized thermographic algorithms to detect rapid temperature spikes and specific flame shapes, allowing it to trigger fire alarms at the earliest stages, before traditional smoke detectors can respond.

What is the advantage of the wide 3.6mm thermal lens?

The 3.6mm lens provides a broad 50.0° horizontal field of view, making it ideal for monitoring wide areas such as entrances, yards, or building perimeters at short-to-medium range distances.

Can this camera measure temperature in specific locations?

Yes. The camera supports up to 21 measurement rules simultaneously, including 10 points, 10 areas, and 1 temperature measurement line, allowing for targeted temperature tracking on machines or panels.

What is the thermal sensitivity (NETD) of this camera?

The NETD is ≤ 40 mK. This exceptionally low noise level allows the thermal sensor to distinguish minute temperature differences down to 0.04°C, yielding high-contrast thermal video.

Does it support Power over Ethernet (PoE)?

Yes. The camera supports standard PoE (802.3af, Class 3) for simple, single-cable power and data installation, in addition to traditional 12 VDC power inputs.

What does the IK10 rating mean?

The IK10 vandal-resistant rating means the camera enclosure can withstand an impact of up to 20 joules, making it resistant to deliberate tampering and physical attacks in exposed locations.

Does the camera reduce false alarms from animals?

Yes. The built-in deep-learning target classification differentiates between humans, vehicles, and animals, helping minimize false alarms caused by wildlife, pets, or environmental disturbances.
