Hikvision has launched a new Bi-spectrum Thermal Bullet camera (DS-2TD2617) that boasts Deep Learning capabilities and a new sensor that improves the quality of its images. A second, optical lens gives operators the ability to verify what the thermal sensor is telling them, without the need for another camera.
Developing earlier versions, the DeepinView camera is equipped with a new improved 160 x 120 pixel sensor in the Hikvision family. This makes the camera more sensitive – detecting to a noise-equivalent temperature difference (NETD) of 40mk (previous sensors went to 50 mk). NETD is an industry standard measurement of a sensor’s sensitivity to thermal radiation in certain parts of the electromagnetic spectrum.
The camera has an optical lens of 4 or 6mm. Using a thermal overlay on the optical lens image, operators can easily and quickly see the pertinent information at the same time. This helps them to understand a situation and act, if necessary. There is also a picture-in-picture capability giving another option for seeing images from both lenses. This also means that there are fewer channels being used in the system.
Based on deep learning algorithms, the camera also delivers powerful and accurate behaviour analysis, including detections such as line crossing, intrusion, region entrance and exit. The intelligent human/vehicle detection feature helps reduce false alarms caused by animals, camera shake, falling leaves, or other irrelevant objects, significantly improving alarm accuracy. In addition, the cameras are equipped with a built-in GPU with advanced imaging processing technology, which can create the best thermal imaging results. These high-performance GPUs can support updates with more complex algorithms in the future to further improve the intelligent effect of Video Content Analytics (VCA).
Other features include:
- Reliable temperature exception alarm function
- Advanced fire detection and smoking detection algorithm
- High sensitivity sensor, supporting contrast adjustment
- Shutter adjustment in various modes
- 3D DNR, 15 palettes of colour adjustable, image detail enhancement.
The camera can be used for solutions incorporating smaller perimeters, like yards or car parks for small businesses. It comes into its own inside buildings, especially where fire protection capabilities are needed, like warehouse and rubbish dumps, where avoiding fire is a priority.
“Combining a new thermal sensor with an optical lens gives operators a lot more flexibility to see what’s going on, and also makes the system more convenient and cost-effective”, says Peter Guan, Director of Channel Sales and Marketing for Hikvision Europe.
