It is a real pitty reolink did not come up with a doorbell camera any sooner, so i already purchased a a other brand.
But beter late then never.
I would like:

• PIR sensor with adjustable senitivity. So moving objects not close to the door are not registered based on image.
• onvif support
• Matching ( multiple) doorbel chime on WIFI so not all house inhabitants need the app installed / dont need my phone in reach. and also can place the chime longer distance away from doorbell.
• Fast resonse in the app on the phone. So no need to do x many clicks before i am able to talk, Design you UI well. My current doorbell suck at this.
• Try to remove latency ( might not alway be possible)
• Face recognitions and based on recognised face different ringtone on phone / chime
• Large field of view. or even beter, adjustable ( manual of digital)
• night vision with selectable areas that are not part of the exposure caculation. I have one object near by my front door and with night vision the exposure calculation make the image very dark due to the overexposure of the nearby object. ( i wish this on all camera's)
• Allow on the back a little space so a few cm excess install cable can fit in to allow for easy install. Or better, allow install wires to be cinnecte to bracked and doorbell plugs in bracket.
•
