Detailed specifications and benefits
Understanding the technical makeup of the DS-2TD1228T-3/QA(B) clarifies why it performs well in challenging outdoor and industrial environments. Below is a breakdown of the major subsystems and the practical benefits each delivers.
- Sensor: VOx uncooled FPA (vanadium oxide)
- Resolution: 256 192
- Pixel pitch: 12 12 '>
Apologies: an internal formatting issue occurred above with the pixel pitch line. Correctly, the thermal pixel pitch is 12 12
- Sensor: 1/2.7" progressive-scan CMOS
- Resolution: 2688 1520 (approx. 4 MP)
- Focal length: 4.3 mm typical (thermal pairing noted at 3.6 mm)
- Aperture: F1.6; field of view approximately 84.0 84.0 x 43.1'
Note: the optical module gives wide-area visible coverage for verification, while the thermal module excels in detection across low-light and obscured conditions. The camera supports IR up to ~15 m for night-time visible imaging and has 120 dB WDR for challenging lighting.
- Image modes: bi-spectrum fusion, picture-in-picture and target colouration (white-hot/black-hot)
- Compression: H.265 / H.264 / MJPEG for efficient network usage
- Local storage: microSD (up to 256 GB), NAS (NFS/SMB), and ANR support to keep footage safe if the network drops
- VCA analytics: human/vehicle classification reduces false alarms and helps prioritise responses
- Measurement rules: configurable points, areas and lines for targeted monitoring
- Range reported: to 550 (verify SKU datasheet)
- Alarms: temperature exception alarms integrate with VCA triggers for multi-modal alerts
- Network: 10/100 Mbps RJ45 with ONVIF support (Profile S/G), Hikvision SDK/ISAPI and secure protocols like HTTPS and IEEE 802.1x
- I/O: RS-485, audio in/out and alarm in/out for integration with alarm panels and external devices
- Power: 12 VDC or PoE (802.3af, Class 3); typical power consumption around 6 6.5 W max
- Environmental: operating temperature -40 to 65 W, and ingress protection rated IP66/IP67
Overall, the combination of thermal detection, visible verification, VCA and temperature rules makes the DS-2TD1228T-3/QA(B) a versatile choice for sites that require early detection and reliable visual confirmation.
Use cases and scenarios where the camera excels
The strengths of this bi-spectrum turret camera make it particularly effective in several common security and industrial scenarios:
- Perimeter protection:Thermal detection spots intruders in darkness, foliage or poor lighting; the optical camera then provides verification images to guide responders.
- Warehouses and logistics yards:Detect people and vehicles after hours, monitor access gates and loading bays, and use temperature rules to spot hot-spots on equipment or stored materials.
- Substations and utilities:Temperature alarms can help identify overheating components or hot-spots while thermal detection supports perimeter intrusion monitoring in remote locations.
- Manufacturing and process plants:Combine thermal inspections for equipment status with visible footage for incident review; analytics like forklift filters reduce nuisance alarms in busy sites.
- Remote or low-light sites:Thermal imaging works independently of ambient light, enabling earlier detection of people or vehicles than visible-only cameras.
How it compares with similar products on the market
Bi-spectrum thermal cameras occupy a range of price and capability points. The DS-2TD1228T-3/QA(B) targets the mid-market segment, offering a balance of thermal capability, visible resolution and analytics. Key comparison points:
- Thermal resolution:A 256 192 sensor is suitable for perimeter and mid-range detection. Competitors with 384 512 or 640 offer longer-range detection and finer thermal detail but at a higher cost.
- Visible resolution:The 4 MP optical sensor provides clear verification imagery. Some lower-cost thermal turrets pair VGA or 2 MP optics; higher-end models may include 8 MP sensors or motorised zoom optics for identification at distance.
- Analytics and temperature functions:Built-in human/vehicle classification and configurable temperature rules are competitive features in this class. Very high-end systems may offer more granular thermal calibration, higher temperature accuracy and additional analytics suites.
- Price and value:With a suggested price around 699.00 (cost price 470.06), this camera is positioned as a cost-effective bi-spectrum option. High-resolution thermal or PTZ thermal solutions typically cost significantly more, while single-spectrum thermal cameras with similar thermal sensors but no visible module may be cheaper but lack verification imagery.
