A subscription will unlock two other features: Person-detection and Zones. Person-detection fine-tunes the Cloud Cam's motion-sensitivity to detect when a person is in the room versus a pet (or Roomba, etc.). There are options to receive notifications of person-detection but not motion-detection, or vice versa, or both. Zones, on the other hand, blocks out certain areas of the room from being detected. So, for example, you can draw a square around the TV or a ceiling fan in the app, and the camera will ignore any motion in those areas.
In my experience, the motion sensors worked really well. It let me know when our cat was on the couch (which is fine) or when she was on the kitchen counter (which is not as fine). Since I also had the Pro subscription, it also let me know someone was in my apartment when my husband walked in. I also tried out Zones with a corner of the room, and sure enough, no matter how much I waved around in that corner, I couldn't trigger the motion sensor.
The Cloud Cam also has geofencing that deactivates the camera when you're home or switches it on when you leave. To enable this, select the "Home/Away" toggle in settings and specify your camera's location. Now, whenever you leave the house (with your phone, of course), the camera will turn on automatically. And when you arrive home, the app will let your camera know you're in close proximity and it'll shut off.
What's nice is that the feature works with multiple phones: If more than one person has the Home/Away feature enabled, all parties need to leave the house for the camera to turn on. If one person arrives home early, then the camera turns back off -- it doesn't need everyone to be home.
While that sounds useful, I had trouble getting it to work reliably. Sometimes when I was home, it wouldn't turn off; sometimes when I was out, the camera wouldn't turn on. When I asked Amazon about this, a spokesperson said to try relaunching the app. I did, which made the camera work as intended, but I ended up having to do this pretty often. It was so annoying that I just decided to turn the camera on and off manually.
Perhaps the main reason you'll want the Amazon Cloud Cam above all other security cameras is that it works with Alexa. Amazon loaned me a Fire TV Stick to use with Cloud Cam, but the company tells me that it will also work with the Echo Show, Echo Spot, any Fire TV product and any Alexa-enabled Fire tablet.
Remember when I signed in with my Amazon credentials during the Cloud Cam's setup? I was also asked to do the same during the setup of the Fire TV Stick -- so that all the Alexa devices could communicate with each other. To test it, I held down the voice button on the Fire TV remote and said: "Alexa, show me the 'Family Room'" (which is what I named my camera) and voilà, live video from the Cloud Cam popped up on my television. I could even use the remote to talk to whoever's in the room with the Cloud Cam, as it has a microphone for two-way communication.
Obviously, this is useful only if you're already invested in the Amazon ecosystem, but if you are, I can see how this would be helpful for keeping an eye on your kids when you're somewhere else in the house.
I should mention here that Amazon plans on selling a different camera called the Key Edition Cloud Cam, which costs $140. This works in concert with a special Amazon Key-compatible smart lock, which is to be used with the Key service (that lets delivery people in the door when you're not home). The Key app lets authorized people in the door, and the Key Edition Cloud Cam will help confirm deliveries or identify friends and family.
Amazon's Cloud Cam is surprisingly affordable for what it offers. It costs $120 for a single unit, but that drops to $100 (or less) if you get a multipack -- a two-pack is $200 while a three-pack is $290. Other brand-name cameras with similar features are more expensive; the Nest Cam is $200, Logitech's Circle 2 is also $200 and Netgear's Arlo is $200 as well. The Blink home security camera is $100, but it doesn't have two-way audio nor geofencing, and it only has 720p video.
Both the Circle 2 and the Cloud Cam offer 24 hours of video as part of the default package, which is great. That's a lot better than the Nest Cam, which doesn't offer any kind of archives at all unless you pay for a Nest Aware subscription.
That said, the Cloud Cam doesn't have facial recognition. For that, you have to either cough up $300 for the Nest Cam IQ or $200 for the Netatmo Welcome. Another downside is that the Cloud Cam needs to be connected to AC power. Logitech's Circle 2 and the Blink camera both run on batteries, so they have way more placement options.
Overall, Amazon's Cloud Cam is a pretty decent choice. It's well-built, affordable and has an advanced motion sensor that can separate people from pets (if you cough up the subscription money). The 1080p video quality is great, the default 24-hour archive is a nice bonus and the night-vision mode isn't bad, either. The geofencing feature is a little finicky, and you can't turn off the camera LED if you want it to be in stealth mode, but I didn't find those to be deal breakers.
If you already have an Amazon device with a screen, like an Echo Show, the Cloud Cam is especially useful thanks to its integration with Alexa. On the whole, I found the Amazon Cloud Cam to be a surprisingly good value for a home security camera, with or without its Alexa tricks.
