Besides this feature, the First Alert Smoke Detector is designed to be compatible with other First Alert and BRK smoke detectors. This compatibility is included in this design to ensure that, as soon as smoke is detected within your home, all alarms would sound and keep you alert. In making recommendations for the hard wired smoke detectors, our research team came across another alarm system model from the First Alert team. Known as the First Alert SCO5CN Smoke Detector, this is a battery operated model designed to act as both a smoke detector and a carbon monoxide detector alarm system. Since its operations are done via the use of cells, users are assured of the continuous monitoring of CO levels in their homes, even in the event of a power outage. Upon detection of any potential hazard, this device makes use of an 85 decibel siren sound, loud enough to be heard from far distances.

Referring to FIG. 7B, the rear exterior surface of the device housing 702 may include a second recess 724B and a third recess 724C configured to cover the heads of the fasteners fastened into the first and second open slots 802 and 804, when the device housing 702 is mounted onto the mounting plate 800. Each of the second and third recess 724B and 724C may have a respective depth substantially greater than the respective head height of the fasteners fastened into the first and second open slots 802 and 804. In some implementations, the mounting plate 800 includes a first fastener structure 806 located at a first end of the mounting plate 800, and the first fastener structure 806 is configured to mate with a second fastener structure 726 located at a corresponding end of the rear exterior surface of the device housing 702. The device housing 702 is mechanically fixed onto the mounting plate 800, when the first and second fastener structures are fastened to each other. In some implementations, the mounting plate 800 includes a third fastener structure 808 located at a second end of the mounting plate 800, and the third fastener structure 808 is configured to mate with a fourth fastener structure 728 located at a corresponding end of the rear exterior surface of the device housing 702. The device housing 702 is mechanically fixed onto the mounting plate 800, when the first and third fastener structures 806 and 808 are fastened to the second and fourth fastener structures 726 and 728, respectively. In a specific example, the third fastener structure 808 includes an extended holding structure, and the fourth fastener structure 728 of the device housing 702 includes a recess hole configured to receive the extended holding structure. The extended holding structure may be pulled out of the recess hole of the device housing 702 when the device housing 702 slides along a longitudinal direction 812A or a transversal direction 812B, but not when the device housing 702 is pulled by a separation force having a direction perpendicular to a front exterior surface of the device housing 702. Further, the first fastener structure 806 may include a snap fastener configured to lock onto the respective fastener structure 726 of the device housing 702. Once locked onto each other, the snap fastener 806 and the respective fastener structure 726 securely hold the device housing 702 onto the mounting plate 800, thereby onto the wall or doorframe surface to which the mounting plate 800 is mounted.

, sets of instructions need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various implementations. In some implementations, the memory 406, optionally, stores a subset of the modules and data structures identified above. Furthermore, the memory 406, optionally, stores additional modules and data structures not described above. In some implementations, the smart device 204 includes a doorbell camera 106, and the doorbell camera 106 has physical features that can provide real time camera status information and/or audio/visual content that indicates or complements camera processing activity, to occupants of the environment without disturbing operation of the camera or the occupants. In some implementations, such physical features include a light ring that is provided at a periphery of a front cover, a periphery of a camera lens, or a periphery of a button on the doorbell camera 106, and is configured to be visible to occupants of the environment from a wide range of positions in the environment. For example, in some implementations, the light ring is configured to be visible in a range of positions that include at least areas of the environment that fall within the camera's field of view. In some implementations, the light ring has a plurality of individual lighting elements, each having associated lighting characteristics that are individually controllable to reflect local camera status and/or a camera processing state/operation. In some configurations, the controllable lighting characteristics include one or more of on/off state, hue, saturation and/or brightness/intensity. In some configurations, the lighting elements are controlled individually to display an overall pattern e. g. , an entire ring or one or more portions of a ring that can be static or dynamic e.
