Tells you when a package arrived and when the neighbor stole it off your porch. Tells you someone rang the bell when not home and lets you remotely yell ant the door to door sales people.

I mean they’re useful, but I sure wouldn’t ever trust one connected to any sort of cloud.

I do have a UniFi door cam that records to a local hard drive. I like it. Ties in with my other cameras to watch my vehicle in my driveway.

If you can see it’s a salesperson you can ignore them but answer if it’s the mailman/UPS. Get notified that a package was dropped off… or that shortly thereafter some rando walks up to said package.

Think of it as a door-peephole-at-range.

Many.

If you get deliveries and they're mishandled, you have a recording of it.

If someone comes to your door when you're not home, you can talk to them.

You can also set up local AI alerts (AI here is mostly used for facial recognition) e.g. to alert you if your MIL comes around uninvited, or if your kids sneak out at 2am, and so on.

Once you begin appreciating a home CCTV camera setup (fully local mind you), you'll see the benefit of having your doorbell video-ed up as well.

In addition to "normal" uses, my kids got into the habit of leaving me messages on the camera when I'm in the office and they are leaving for school. I grew to love these messages.

Using Eufy with local storage. Don't know whether anything gets stored to the cloud, but I guess data still passes through Eufy servers when I view the videos.

1. Not getting off the sofa. Video doorbell pops up on my watch, no matter where I happen to be, so I can immediately decide whether it can interrupt what I’m doing.
2. Shut the hell up. Sometimes I turn off the chimes so I’m not bothered by yet another door to door sales drone. But I still have my watch in case whoever is at the door is legitimate
3. Intercom. My kid sometimes want to tell me something without coming inside
4. History. Yes, sometimes I want to scroll back through all motion trigger s in front of my door
5. Wildlife. Minor feature but it is occasionally fascinating to see what animals amble in front of my door. I’m urban so it’s limited but we have turkeys and coyotes

How else can you have the pleasure of telling Jehovah’s Witnesses to go away when you’re not at home?
