Amcrest - AD110

The Amcrest wired one has a 128GB SD card slot and is wired. My home is using a few Amcrest products.

I use an Amcrest doorbell.  No subscription.  It will both store locally to an sdcard in it, and my GW Security NVR records the rtsp stream from it 24x7.  Integrates with HA through their api for a human detection sensor and the doorbell sensor.

Amcrest Doorbell Cam with Scripted Nvr in proxmox works great for me. Scrypted is integrated into HA as well

I’ve been using Amcrest for 4 years now without issue. I have a wired doorbell camera and a turret camera on my garage. They offer cheap online hosting or you can do it on your own too. 

Amcrest is good if you don't want to do POE and have a mechanical doorbell. Just swapped out my Nest for one last month, no complaints.

Amcrest to frigate and home assistant to push the notification and pop up the live feed. Works well enough for me.

This is true for cameras but less so for doorbells. An awful lot (almost all) of doorbells are 'smart home' products, that don't just have a basic web interface but rather force you to use some shitty app. Take the amcrest one- it'll work locally with a NVR, but you still have to configure it with an app, and if you cut off its internet connection to Amcrest cloud the LED blinks differently. Cameras there's plenty of options that are happy to work locally. Doorbells, not so much. Ubiquiti UniFi is one, I think Dahua also has one. Reolink too although you may need an app to set it up.

I have the Amcrest one along with a couple of their PoE cameras, they work great and integrate well with both Home Assistant and Blue Iris. Although I do use their app with an account to use the talk feature occasionally. For just the video feed, notifications, and recording, Blue Iris does the job locally just fine.

I use an Amcrest video doorbell which us ONVIF compatible, the open standard used by security cameras. That makes sense because security cameras is their main business. I have it connected to my home automation system so we can access it through our phones or a few wall mounted tablets around the house. It can also store the video to an SD card if you prefer and can be accessed locally with an app that doesn't require a subscription. Yes, they offer a cloud subscription if you like, but it is optional, but not using it means you need to set up your own remote access if desired.
