It is water and weatherproof as well. I believe that it would stand up fairly well to many types of vandalism. Also, having installed this in various locations both outside and inside my home, I am confident in saying that this particular model is very resilient. It will stand up to normal weather conditions. It will probably stand up to harsher conditions, as long as the do not reoccur on a consistent basis. I actually installed one of these bad boys I guess it could be a bad girl also, depending on your perspective near my front door. I initially just wanted to get an overall impression of how it worked. My experience was generally pretty positive. The camera shows good detail to a range of about 25 feet or so. It can see beyond that, although it loses so clarity. You would not really be able to see the details of a face beyond this range.

The only gripe we have is the relatively short warranty. The smoke sensor in the Nest Protect is different than any other smoke alarm we've looked at. The unit uses a split spectrum sensor, a special type of photoelectric sensor, which is designed to detect both smoky and flaming fires. The Nest Protect also has a built in a carbon monoxide sensor and will sound an alarm if it detects dangerous levels of the invisible, odorless gas which can be lethal if you breathe it for too long. To help cut down on false alarms from steam and burnt toast, the Nest Protect also uses humidity and heat sensors. We tested the detection capabilities of each smoke detector in our comparison by spraying test smoke from an aerosol can directly at each one from 5, 10 and 15 feet away. When we tested the 5 and 10 foot mark, the Nest Protect sounded its alarm after 18 seconds. At 15 feet, the alarm activated at 28 seconds. It should be noted that Nest Protect was the only smoke detector that passed all of our detection tests. Half the devices could not detect our test smoke from 10 feet away and only Nest Protect sensed danger from the 15 foot mark. All smoke alarms feature a loud blaring tone to alert you to potential dangers in your home.

FIG. 3B illustrates various data structures used by some implementations, including an event record 3168 i, a user profile 3163 i, and a device profile 3165 i. The event record 3168 i corresponds to an event i and data for the event i. In some instances, the data for motion event i includes event start data 31681 indicating when and/or how the event started, event segments data 31682, raw video data 31683, event end data 31684 indicating when and/or how the event ended, event features data 31685, scene features data 31686, associated user information 31687, and associated devices information 31688. In some instances, the event record 3168 i includes only a subset of the above data. In some instances, the event record 3168 i includes additional event data not shown such as data regarding event/motion masks.
