AI驅動 3K+ Guard WIFI 三鏡頭 PTZ 安全攝影機，3入

I've had these up for about a week and the PTZ tracking is surprisingly smooth—follows my dog across the yard without lag. The 3K resolution lets me read license plates from down the street, which my old cameras could never do.

The tri-lens setup covers my whole driveway and side gate without blind spots, which two single-lens cams never managed. Panning to follow my dog across the yard is smooth and the 3K resolution makes license plates readable.

Night vision picked up a raccoon on my driveway around 2am and the 3K detail was sharp enough to see its face clearly. The PTZ tracking follows movement smoothly instead of jumping around like my old cam. Three of them covered the whole backyard for less than I expected to pay for one.
