motion activated camera for entry doors

I would like motion activated cameras for my entry doors that will alert me
when someone approaches door

You have a couple options for such an application.

You could get an outdoor camera that uses Video Motion Detection, like the ADC-V720W, and position it so it captures the front entryway.


You could get the ADC SkybellHD doorbell. It uses PIR to detect motion and has live video and two-way voice through the app. It also lets you record motion events.

Both options would require the Video Add-On.
