AI POWERED Sentinel 4K Ultra HD 有線16路 PoE NVR 安全監控系統 16支金屬攝影機 2TB硬碟

The AI-powered motion alerts have cut down on false triggers from passing cars, which was my biggest frustration with my old system. Colors are sharp even at night, and the 2TB HDD already holds about a week of footage. It's a beast to install but worth it for the clarity.

Took a full weekend to wire all 16 cameras myself, but the PoE setup made it way easier than I expected since each one only needs a single cable. The AI detection has already pinged my phone twice for a stray cat near the driveway, and the 2TB drive gives me about a week of continuous 4K footage bef

The 4K picture on these metal cameras is absurdly sharp, I can read a license plate from across the street. The AI detection actually filters out my neighbor's cat instead of lighting up my phone all night. Wiring all 16 through PoE meant no power runs to each camera, which saved me a ton of work.
