Our favorite feature was the pre recorded responses that inform visitors to leave a package, wait for someone to come to the door or saying no one is available. During our tests, we found that the Nest Hello produced the second best video quality, tying with RemoBell, only Ring Pro had better video. Nest Hello has a slim form factor that fits on most doorframes and is the only video doorbell we reviewed with a two year warranty. It's a great option if you have other Nest devices in your smart home but has limited smart home functionality otherwise. If you want to record video, you can pay $5 a month, which is more expensive than other video doorbell storage plans in our comparison. The Nest Hello costs around $230, making it more expensive than average, but still more affordable than Ring Video Doorbell Pro.

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. There is a voice alarm, a flashing light, along with a loud beeping sound that warns of danger. The Kidde KN COSM B Battery Operated Combination Monoxide alarm needs 3 AA batteries to operate and comes with a 5 year warranty.
