A computer-implemented method for premises security is described. In one embodiment, a person passing through a perimeter of a predefined area is detected via a boundary sensor. Upon detecting the person passing through the perimeter of the predefined area, a camera is activated to capture an image of the person, the camera being positioned in relation to the predefined area. A notification is sent to a user determined to be nearest to the predefined area. The notification may include the image of the person. A proximity of a person in relation to a vehicle is detected via a proximity sensor. Upon determining the proximity of the person satisfies a predetermined threshold, a notification is sent to a user. Upon determining the proximity of the person satisfies the predetermined threshold, a camera positioned in relation to the vehicle is activated.
