If we take into account the backplate, the First Alert 2 in 1 Z Wave is thicker than your average smoke detectors, measuring 5. 0 x 2. 0 x 5. 0 inches but it’s fairly lightweight, weighing only 1. 0lb. This particular model does not come as a hard wired detector, the only way to power it remains through the use of batteries and the only smoke/CO detectors from First Alert that can be connected to the home’s power source are the 120V AC Smoke and Carbon Monoxide alarm and the already mentioned OneLink detector.

The photoelectric sensor does the best job in detecting smoldering fires. The First Alert SA320CN Double Battery Powered smoke detector has a loud alarm so it can be heard throughout the house and responded to quickly. Rest at ease, and have the peace of mind that your home is protected with the First Alert SA320CN Double Battery Powered smoke detector. It comes with a 10 year warranty. The First Alert operates with AA batteries and should be checked twice a year for battery life. The Kidde KN COSM B Battery Operated Combination Monoxide detector is a combination smoke and carbon monoxide detector. Carbon monoxide is an odorless and tasteless gas that can kill residents even when low amounts are inhaled. Instead of having both a carbon monoxide detector and a smoke detector, this unit combines the two into one unit. For the smoke detection the unit includes ionization sensing technology, which detects visible fire particles and warns of impending danger. The carbon monoxide alarm goes off if the carbon monoxide levels in your home increase to a dangerous level. The Kidde KN COSM B Battery Operated Combination Monoxide has four verbal warnings including fire, carbon monoxide, low battery and smart hush announcement.

In some implementations, the sensor board 1108 also includes a connector for communicatively coupling the sensor board 1108 to the image sensor array 1114. In some implementations, the image sensor array 1114 and/or the image processor of the sensor board 1108 is thermally coupled to a heat spreader 1138 that is disposed under the image sensor array 1114 and configured for dissipating heat generated while images are being captured and processed. The sensor board 1108 may include one or more of a power supply connector 11082, an AC DC converter 11084, a voltage regulator 11086 and a power unit 11088. The power supply connector 11082 is electrically coupled to the plurality of wire terminals 720, and configured to receive an external power supply. The AC DC converter 11084 is coupled to the power supply connector 11082 and configured to generate one or more DC supply voltages to drive various electronic components of the doorbell camera 106. The voltage regulator 11086 is configured to regulate the one or more DC supply voltages to one or more internal supply voltages as needed.
