There are many options available.
Logitech has a variety of
security systems. Both indoor and outdoor. Our older system continues to work well. When we're travelling I receive email alerts when there is movement along with a snapshot, but it has usually wildlife and the wind that triggers the camera.
Bushnell's outdoor cameras (trailcams) are also effective. Some have a Wi-Fi option. I have the trailcams without Wi-Fi because we don't have cell service in our area. The cameras work at temps down to -40 and it is mostly wildlife photographed along our driveway.
