Adopting the unique TandemVu dual-lens design: one 2.8mm wide-angle lens (horizontal field of view approximately 94°) is responsible for monitoring a wide area, while the other 8mm telephoto lens (horizontal field of view approximately 44°) is responsible for monitoring distant details; both lenses have 4MP (2560×1440) ultra-high-definition quality, capable of simultaneously outputting two video streams. A single unit can cover both "panoramic view of the compound" and "close-up shots of the entrance/lanes", completely eliminating visual blind spots. Equipped with (intelligent hybrid light) technology, integrating IR infrared and warm white floodlights (each with a range of up to 30 meters), supporting 3 lighting modes: default IR does not disturb residents, automatically switches to white light full color when an event is detected, or always on full color mode, ensuring full-color evidence of critical events while effectively reducing light pollution; the telephoto lens supports PT (Pan/Tilt) rotation (horizontal 0°~345°, vertical 0°~80°), allowing remote control of the angle or setting 300 preset positions and automatic cruise, flexibly adjusting the close-up perspective. Built-in intelligent algorithms, supporting precise detection and classification of human figures and vehicles, capable of filtering out animals, leaf movement, shadows, etc. Support for motion detection and alarm push, only pushing true security threat alerts, saying goodbye to invalid notification bombardment, making the monitoring more intelligent. Supporting 12V DC and standard IEEE 802.3af/at PoE power supply, one network cable solves both data transmission and power supply; built-in high-sensitivity microphone and speaker, without additional wiring, can achieve real-time two-way voice communication and audio monitoring; the body comes with a Micro SD card slot (max. 512GB local recording), no data loss when disconnected from the network, and also supports centralized storage by NVR. Using H.265+ intelligent compression, while ensuring the 4MP quality of both video streams, significantly reduces bitrate and bandwidth usage (compared to H.264, it can save approximately 50% more), extending the storage cycle; the entire machine reaches IP66 dustproof and waterproof level, working temperature range from -30°C to 60°C, not afraid of rain, dust, and temperature changes, suitable for long-term stable operation in outdoor environments such as rooftops, fences, factories, and campuses., Manufacturer: QINGLUSHANGMAO
