Caméra de sonnette sans fil XTU J10 avec carillon

What I noticed is when I leave the house, it will activate the camera that will follow me until I leave the defined monitoring perimeter, but it is not activated when I enter the perimeter until I am almost next to the camera. Is this normal? Is there a range limit for the camera to be activated? What if someone enter the perimeter but does not come close to the camera?

Good camera but mount adhesive will not hold the camera in place to metal.

The camera itself is awesome but negative side is that you're sds card is exposed anyone can removed they should have better plan for this issue no im thinking to create a security box around the bell to protect as much possible

Video and voice quality is very good, battery last a lot, and the design is nice, however I miss some features:
-A bell icon in the button to make it more intuitive for visitors
-Compatibility with Google home is poor, I can't see video automatically in google nest display, I need to ask to show it.
-Memory card is very accesible and can be stolen by anyone
