Can anyone recommend an ip camera to monitor my street door, preferably one that can fit on the door and be visible to also act as a deterrent.
My door is inside an open porch so an internal camera would be OK.
People don't usually fit cameras on the door, due to the hassle of cabling.
They're usually fitted alongside or just above.
Perhaps consider the HikVision 2532 or 2132F models.
I'd suggest a 2.8mm variant giving a 90° field of view as subjects are likely to be fairly close to the camera.
