Abstract: This application discloses an electronic device (e.g., a camera) that operates at two distinct modes and includes a camera lens configured to capture visual data of a field of view, a plurality of light sources, and a light source driver. The light sources are configurable to a plurality of light source subsets to illuminate the field of view. At least two of the light source subsets include distinct light source members and are configured to illuminate different regions of the field of view. The light source driver is configured to drive the light sources with two distinct drive voltages at two distinct modes. In a first mode, the light sources are electrically coupled to each other and driven by a first drive voltage. In the second mode, one of the light source subsets is selected and driven by a second drive voltage that is lower than the first dive voltage.

Abstract: Doorbell camera systems are provided that can include a doorbell camera subsystem and a chime subsystem. The doorbell camera subsystem may include, among other features, a camera module and a doorbell button. The chime subsystem may include, among other features, a battery and electronics that interface with a chime such as existing doorbell chime or a speaker. The battery is co-located with the chime subsystem and away from the doorbell camera subsystem. Co-locating the battery with the chime subsystem removes the battery from potentially harsh environmental conditions it would otherwise be subjected to if it was co-located with the doorbell camera subsystem.

Abstract: This application discloses a camera including a camera lens, a plurality of light sources and bypass circuit. The camera lens is configured to capture visual data of a field of view, and the light sources are configured to illuminate the field of view. The bypass circuit is coupled to the light sources, and configured to group the light sources into a plurality of light source subsets. At least two of the light source subsets include distinct light source members to illuminate different regions of the field of view of the camera. The camera includes a first mode in which the light sources are electrically coupled in series to form a string and driven by a boosted drive voltage, and a second mode in which one of the light source subsets is selected and driven by a regular drive voltage that is lower than the boosted drive voltage.

Abstract: Systems and methods for interfacing a hazard detection device with a control panel system via a dongle are provided. The dongle may be configured to alternate between drawing first and second amounts of power from the control panel system in response to the hazard detection device alternating between operating in a normal mode when no hazard is detected and an alarm mode when a hazard is detected. The hazard detection device may operate independently of any characteristics of the control panel system. For example, the hazard detection device may operate without drawing any power from the control panel system. Therefore, the dongle may allow for various types of hazard detection devices to interface with a common two-line power control system.
