Extra Info
Thermal and Optical Bi-spectrum Technology
This camera integrates two powerful sensors: a thermal module and an optical module. The thermal sensor detects heat signatures, allowing for clear visibility in total darkness, fog, or smoke, and is crucial for accurate temperature measurement and fire detection. The optical sensor provides traditional high-resolution color video, offering detailed visual information for identification and general surveillance. This combination ensures comprehensive coverage and robust security, day and night.
Smart Detection and Prevention
Beyond basic motion detection, the DS-2TD1228-7/QA features advanced Video Content Analysis (VCA). It can accurately classify targets as either human or vehicle, significantly reducing nuisance alarms from irrelevant movements. The camera's temperature measurement capabilities are precise, enabling it to trigger alarms if temperatures exceed predefined thresholds, which is invaluable for preventing fires in sensitive areas like warehouses or manufacturing workshops. It even supports specialized algorithms for smoking detection and includes a sun-reflection filter to maintain image quality.
Versatile Application
Designed for flexibility, this camera is suitable for a diverse range of environments. From monitoring private residences and community areas to securing parking lots, construction sites, and critical industrial facilities, its comprehensive features make it an ideal choice. The ability to detect temperature anomalies and classify targets makes it particularly effective for loss prevention and safety monitoring in complex settings.
