A method including, at a camera, detecting motion in a field of view of the camera using a motion sensor, initiating processing of video data corresponding to the field of view in which the motion was detected, ceasing the processing after a first time duration, and determining a cool-off period for the motion sensor, the cool-off period having a second time duration based on the first time duration during which the camera does not detect motion using the motion sensor.

Event length dependent cool-off for camera event based recordings

Sensor-based privacy-event detection for a mounted electronic device is described. In aspects, a security system includes a head assembly removably and magnetically coupled to a mounting device having a magnet. The electronic device also includes a camera module and a sensor disposed within the housing. The sensor detects a magnetic field associated with the magnet when the head assembly is coupled to the mounting device. When a user detaches the head assembly from the mounting device (e.g., to recharge the electronic device), the sensor no longer detects the magnetic field and determines the occurrence of a privacy event, which is used to deactivate the camera module to prevent unintentional recordings during the privacy event.

This document describes a security camera with an angled cable attachment for an increased downward viewing angle. The security camera is battery-powered and can be magnetically coupled to a mounting device and electrically connected to another device via a cable. The cable has a cable attachment that, when coupled to the security camera, is angled toward a front of the security camera. This cable angle enables an increased downward tilt angle of the security camera by reducing interference of the cable attachment with the mounting device when the security camera is tilted downward. The security camera also has exposed contacts on a printed circuit board that connect with pins on the cable attachment.

Security camera with angled cable attachment for increased downward-viewing angle

An electronic device including a mounting device configured to couple to a surface, a head removably coupled to the mounting device and including a housing, a magnet attached to the mounting device, and a sensor disposed within the housing. The sensor detects a magnetic field associated with the magnet when the head is in a first position relative to the mounting device and detects the magnetic field associated with the magnet when the head is in a second position relative to the mounting device, the second position being different than the first position.

Sensor-based tamper detection for mounted electronic devices

Methods of the disclosed subject matter provide compensation for sensor drift in a hazard detection device having a plurality of sensors coupled to a processor to determine that a carbon monoxide sensor is drifting and to compensate for the drift by calculating a corrected carbon monoxide measurement value based on the ambient environmental conditions.
