As you know, the smoke alarms use two types of sensors to detect any life threatening emergencies: the ionization sensors to detect fast burning fires and the photoelectric sensors to detect fires in their early stages smouldering fires. The ionization sensor uses a chamber filled with ionized air and, when smoke enters it, the sensor triggers the alarm. Because of its nature, the ionization sensor tends to be more sensitive at detecting small particles, therefore more often triggering false alarms. The First Alert 2 in 1 steered clear of the ionization sensor and only went for the photoelectric type. The photoelectric sensor is better suited at detecting larger particles usually from smouldering fires, that don’t erupt immediately into flames by using a light beam inside the detector which doesn’t directly hit the sensor, but will do so in case smoke enters the device and forces the light towards the sensor. Besides the smoke detecting sensor, the First Alert 2 in 1 also has a Carbon Monoxide Electrochemical sensor which has the role of detecting any rising levels of CO inside the room and triggering the alarm when the concentration crosses the safety levels there will be both visual and audible signals – up to 85dB at around 10 feet.

, one or more rotating portions of a ring consisting of a single displayed color or two or more different displayed colors. Each of the patterns can conform to a visual language and correspond to a camera status and/or a camera processing operation. For example, a color or a pattern of two or more different colors static or dynamic can indicate that the camera is on or off, has an active or inactive connection to a server e. g. , a server that performs image processing or that distributes video and notifications to remote users, is actively processing local information from the environment, or has received a notification or status information from another smart device in the home environment or a server. In some implementations that include a speaker, the physical feature e. g. , a light ring can be controlled by the camera to display patterns that correspond to audible beats/rhythm of music or audio messages being played from the speaker in a range of colors selected to match the tempo/feeling of the music or audio messages. Providing such information via light patterns is advantageous as this is readily perceived by all/most users in the environment even if they do not have access to camera smart phone application without intruding on activity of occupants in the environment, as audible alerts could do sometimes.
