Ionization type sensors are best at detecting fast burning fires, while photoelectric sensors are generally better at
alerting you about smouldering, or slow burning fires. You should have both types of alarms in your house. Smoke alarms such as the Nest Protect are designed to pick up both types of fires. Carbon monoxide and other gas detection. Even if you don't have a fire in your home, you can be suffocated by carbon monoxide. A good detector should also protect you against this. Hardwired vs. Battery powered. If your home has hardwired alarms, they will all be interconnected, so that if one goes off, they all will go off. Hardwired alarms also receive their power from your home, and only use
batteries as backups. Standalone detectors run on batteries alone, so they may need to be replaced more often, and cannot signal each other in the event of an emergency Nest's and OneLink's alarms are an exception to this.

In
accordance with the supply monitoring signal, the LED indicator displays on a surface of the doorbell housing one of a set of predetermined visual patterns, thereby sending a visual message to a user of the doorbell camera to indicate whether the input AC voltage is low with respect to the supply threshold. In some implementations, the camera module is configured to in accordance with a determination that the input AC voltage is not
greater than the supply threshold, disable capturing images and exchanging data with a remote server, and enable communication with a client device via a short range communication link. Alternatively, in some implementations, the camera module is configured to activate a low power mode in accordance with a determination that the input AC voltage is not greater than the supply threshold. In another aspect of the application, an electronic device includes a device housing and a waterproof button assembly. The device housing encloses at least a plurality of electronic components and includes a front cover plate having an opening. The waterproof button assembly is formed in the opening on the front cover plate of the device housing.
