The second - generationNest Doorbellis the first shelling - powered variant of the equipment from Google , equip with various barrage fire - economise feature of speech by default . But even though you could plug in the Modern Nest Doorbell via top executive wire , it wo n’t support around - the - clock video transcription .
Google says that ’s because wiring the electric battery - powered Nest Doorbell introduces “ thermal challenges , ” because it is n’t large enough to dissipate the heating needed to stay regulated when the Lord’s Day is blaring down .
This revealing comes from athreadin the official Nest bomber - Reddit , initially discovered byAndroid Police . I reached out to Google , and a interpreter confirm that passion is indeed the reason .

Inresponseto a few queries on whether the unexampled Nest “ electrify devices ” had 24/7 recording abilities , a Google community manager respond that the Continuous Video Recording ( CVR ) feature is available on all devices except for the battery - power Nest doorbell . “ That ’s because tot CVR to Nest Doorbell ( stamp battery ) consumes a lot of zip , and would pose some thermal challenges , ” write the residential district manager . “ This would have required us to make the buzzer bigger . ”
The same community of interests manager elaborated on the specific “ challenges ” in anotherthread . “ In pumped up configuration , also it mystify thermal challenges for a equipment that ’s stamp battery - operated and likely to be in direct sunlight , which requires large computer hardware enclosures . ”
Consider this a public service announcement for the one concession you have to make to keep off having your doorbell television camera spontaneously combust . It ’s also a entrancing insight into what Google has to consider as it ’s manufacturing outside computer hardware . With so much disparity between climates , it makes sensation to turn off out a feature like continuous recording , which is alreadyquitetaxingon cyberspace bandwidth .

I ’ve seen at first hand what the sun can do to a doorbell photographic camera , though not in this accurate scenario . I still have the original Nest Hello , now categorized as the Nest Doorbell ( wired ) in the Google Store . I mentioned in myreviewthat three year into using it , I noticed the plastic warping around the border of the doorbell bod . The sun and oestrus remain the probable culprits . The original doorbell is still available for leverage if you want a wired photographic camera with 24/7 connectivity . It ’ll be interesting to see how the lustrelessness finish of the new Nest Doorbell , which increased in size over its herald , holds up over time .
If you want a Nest camera that can do uninterrupted recording , you could opt from any other fashion model available from Google , including thereimaginedbattery - powered Nest Camera . Our review of that twist is coming soon .
