What's that latest and greatest (cheap) video doorbell that doesn't need the cloud to work with BI and/or an NVR? I have a Secur360, super cheap (less then 20 on ebay), it works ok, had it for many years but recently I had to turn off the physical chime option because every time the button was pushed it would lock up and need to be rebooted and the chime wouldn't ring. It seemed to work good from the start and for 20 bucks was just what I needed. Might just need to get another one but wondering if there's anything else out there similar.
