Only problem with horizontal orientation in order to maximise head to toe as I see it, is that it's more difficult to locate the camera on a door frame!

Hi there, about the FOV, thank you for pointing out the shortage. I have discussed this with our product manager. We will keep collecting your request to better improve the doorbell product line.

This late in the game it may be difficult to implement hardware changes, but what about software?

If I mount the doorbell horizontally can you get the software to correct the video?

Assuming the camera is tied to an NVR or triggers the app on a phone, does it really matter as the image will still record and be viewable and probably fit the screen....

I think Reolink will loose a lot of sales without head to toe camera or this doorbell, especially as users of Reolink products want a supplementary camera to cover the immediate area of the front door especially since this is where packages are left. It's a pity that the whole camera module couldn't be made to be twistable by 90 degrees to be able to cater for people that wish to have wider horizontal or vertical formats. That would be a good compromise, as possibly the 140 degrees angle could almost be sufficient! However I suspect the camera is mounted directly to the main board and this wouldn't be possible without redesign!

I agree with most of the comments here regarding a head to toe camera. I think you need to re-evaluate the aspect ratio on this camera, even if the sensor was just rotated 90 degrees it would be better with 140 degrees top to bottom. And if you placed a slightly wider angle lens on it then in my opinion the product would be far more usable. Even a fish eye lens can be corrected for in software with a lot of DVR programs being able to correct for this when displaying the picture.
Plus the product page as is, does not indicate how the non Poe version is to be powered... These details are only to be found from the product FAQ page - existing door bell power (12-24V AC or 24V DC).
