Abstract: An apparatus includes: a video camera configured to acquire a video of a monitored physical space, a computer-based memory buffer configured to store temporarily a portion of the video acquired by the video camera as it is acquired, and an actuator configured such that operation of the actuator causes, for a period of time, any video subsequently acquired by the video camera to be saved to a computer-based memory device other than the computer-based memory buffer.

Abstract: A method includes: collecting data about a first event at a first physical space using a first electronic monitoring device that is physically located at the first physical space, enabling the collected data to be displayed at a computer-based user interface device (e.g., at a user's a smartphone that may be remotely located relative to the first electronic monitoring device), enabling the user to describe, using the computer-based user interface device, the first event represented by the collected data, and storing, in a computer-based memory, a logical association between the user's description of the first event and one or more characteristics of the collected data.

Abstract: In a system for monitoring a location, where the system includes a plurality of security sensors at the monitored location, at least one computer-based processing device, a computer-based memory, and one or more computer-based user devices, a method that includes: receiving, at the at least one computer-based processing device, data from the plurality of security sensors that relates to the monitored location, determining, with the computer-based processing device, whether the data meets a criterion; and sending a first notification to one or more of the computer-based user devices if the criterion is met.
