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. 

Which lock are you paying a monthly fee for? I would drop that in a second. The whole key to home automation is local control. I use Home Assistant with Schlage Zwave lock - my doorbell camera is amcrest. I have a number of other cameras, switches and sensors, etc all local through Home Assistant. The only thing I pay for is the subscription to Nabu Casa - the home assistant cloud for remote access. $8.70 CAD a month. There are ways to do it for free, but I have no problem paying these guys as a way to support there awesome product.

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.

I have Home Assistant running frigate, Schlage z-wave doorlock, Amcrest doorbell/camera. I get notifications with pictures on my phone when the amcrest detects a person. No fees. local storage.

I've run an Amcrest doorbell, which is just a Dahua in disguise but more friendly looking. Two actually since both of them died. And I currently have the Reolink and couldn't recommend it more. I've worked for years in video surveillance so I also have multiple thousand dollar cameras on my house and the Reolink does just fine against those. I also have a full Unifi setup and would never go with that doorbell. It just isn't worth the cost for zero performance upgrade and to be locked into Unifi for an NVR. Reolink is better supported in Home Assistant, but more importantly, in Frigate. It has no subscription and actually has a really nice app if you ever just wanted to use that. Amcrest/Dahua, and the Reolink, both work with RTSP, you can get 2-way audio with Reolink. I couldn't with the Amcrest/Dahua. The biggest thing that people don't talk about is how much easier Reolink's doorbell is at meshing into existing chime's. You can simply bypass a chime and use their siren, which is super loud and has fun noises (for the kids), and it won't interfere with a dual doorbell, single chime setup (ie Reolink on front door, normal doorbell on backdoor). The amcrest / dahua doorbell was a nightmare. Also also, my Reolink has now survived sub-zero new england winters and above 100 degree, direct sun, California summers so...it'll do just fine.

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.
