Yikes!
Here's another, apparently for $20 USD => 48V POE to 24V DC converter 24W POE splitter for 24V passive POE Accessories

I recently tried to have the doorbell ring also on my phone app, so that if I'm too far from the actual chime, I can hear the doorbell, but I don't find a way to enable this in the app, without also enabling notifications for motion which then floods my phone anytime someone walks in front of the house. Is there a way to just have the app ring when the doorbell button is pressed, with no other notification? I'm on Android, for reference.

Wonder if it is an AI post? I read that companies are using AI to scour the Internet for negative post about their products.FWIW, the member you replied to passed away in Feb. of 2023.
Could be.
If it is, let's see how long it takes our recently AWOL admin to deal with it.
Be careful - I could be mistaken, but I think the doorbell is designed for 24VAC (traditional doorbell AC transformer), not 24VDC. You could end up frying it.
Just picked up a refurb POE doorbell and so far so good. I flashed it to the latest firmware and am pleased to find that adding it to my Dahua NVR as an ONVIF protocol device works fine, including ONVIF motion detection. My only issue at present is that despite choosing constant framerate and bitrate for main and sub stream, playback of the captured stream on both Blue Iris and on my Dahua NVR has video speed and video-audio sync issues. It is as if the reported frame rate is not the same as the encoded frame rate. The audio plays at normal speed while the video races. Does anyone else have the same observation? Is there a known fix? Thanks.
Alternate stream might work for video but I'd be forfeiting the ONVIF motion events. Not so much an issue for Blue Iris (CPU utilization would tick up though), but my Dahua NVR doesn't do video analysis for software motion detection, it relies on protocol motion detection events from the cam.
I have attached two identical segments, one extracted from my NVR using DMSS, and the other extracted from the POE Doorbell's microSD card, using the ReoLink desktop application. My NVR captures the POE Doorbell's RTSP stream via the ONVIF protocol.
If you playback both clips in VLC, you will see the NVR-extracted clip seems sped up. If you inspect the properties of both files, you will see in the details that the NVR clip indicates an fps value of 40, whereas the ReoLink clip indicates 20.9. Also worthy of note, the NVR extracted clip file size is about half of the ReoLink clip file size. Perhaps the ReoLink application is re-encoding the video on extraction, or perhaps the ONVIF RTSP stream only contains every other key frame.
The unusual nature of this is only an issue if I'm playing back multiple NVR channels in-sync. Somehow, my NVR manages to start all the cams at the same timecode regardless of which channel has focus in the multi-channel playback window, but the doorbell always races ahead. If ever I need to extract video from that channel, I can always re-encode it and drop the frame rate so the audio and video will sync and playback speed would be normal.
Another thing I've noticed when monitoring the network bandwidth occupied by my POE cams, is that the ReoLink doorbell is a bit of a bandwidth hog. It often peaks at 2-3x the target bandwidth of the combined main and substream settings. It is cam number 2 in the image below.
Stream settings:
Despite all of this, I think it's a great doorbell cam, and definitely an upgrade to the Amcrest AD110 it replaced. The google & alexa integration works flawlessly, which is not something I could say for the doorbell it replaced, and I'll take hard-wired over wireless for a cam any day.
