4K 8MP 4MP Vari-focal Web Cam Smart Dual Light With SD Cart Solt Mic Network Camera(4MP White)

- Offer 4K (3840×2160) or 4MP (2688×1520) high-definition quality options, significantly enhancing clarity compared to 1080P; equipped with a 2.7mm - 12mm (or 13.5mm) motorized varifocal lens, allowing remote adjustment of focal length and focus directly through the mobile app or computer client without the need to climb a ladder. Installation and setup are extremely simple. - Equipped with Smart Dual Light technology, featuring IR infrared lamps and warm white supplementary lights; supports three modes: always-on infrared (black and white concealment), always-on white light (full color), and Smart intelligent mode (default infrared, automatically turns on white light and full color when someone or vehicle triggers, automatically switches back to infrared when no one is present); ensures color evidence for critical events, reduces light pollution and mosquito problems caused by constant white light, and the night vision distance typically reaches 30-60 meters. - Equipped with high-sensitivity microphones, enabling real-time audio monitoring or recording without the need for an external audio cable. In case of disputes, not only is there a video, but there is also clear and reliable audio evidence. Equipped with a Micro SD card slot (usually supporting up to 256GB - 512GB), supporting local events or continuous recording. In the event of a network outage, recording does not stop. Data is more secure and often supports FTP/NAS and NVR storage. - Supports 12V DC and standard IEEE 802.3af PoE power supply, using a single network cable to simultaneously solve data transmission and power supply, making deployment extremely simple; features 120dB true wide dynamic range (WDR), ensuring that in scenarios with strong backlighting at the door, indoor bright light, or large contrast between light and dark, the bright areas are not overexposed and the dark areas have gradation, ensuring both clear faces and background details. - Uses a metal or high-strength material casing, reaching IP67 dustproof and waterproof standards, unafraid of rain, dust, and temperature changes, suitable for long-term stable operation in harsh environments such as roof edges, exterior walls, and corridors; uses H.265+ intelligent compression, ensuring high-definition quality while significantly reducing bitrate; deeply compatible with common protocols, seamlessly integrating with various PoE NVR or VMS platforms, usually managed remotely through the manufacturer's app, computer client, or web interface.
