Hikvision DS-2TD2628-3/QA Thermal & Optical Bi-spectrum Network Bullet Camera supports video analysis for perimeter protection, and also temperature exception alarm for early fire prevention. With the deep learning algorithm, it can realize high precision VCA detection and real-time alarm. These camera series can be widely applied to villas, communities, parking lots, warehouses, construction sites, waste incineration plants, manufacturing workshops, etc

DRI Range Table
* The table is only for reference and the performance may vary according to different environment.
* The optimal detection, recognition, and identification distances are calculated according to Johnson’s Criteria.
Detection Range: In order to distinguish an object from the background, the object must be covered by 1.5 or more pixels.
Recognition Range: In order to classify the object (animal, human, vehicle, etc.), the object must be covered by 6 or more
pixels.
Identification Range: In order to identify the object and describe it in details, the object must be covered by 12 or more
pixels
