Anyone know if it is possible to have a home installation with a hard drive recorder which includes a video doorbell like the Ring system. A system that would provide a mobile phone alert, 2 way audio whilst recording to local hard drive along with other cameras on the installation ? I’ve looked online but can’t seem to find anything. We have a Ring system right now but it’s stand alone and also has an annoyingly long delay in between the doorbell being activated and the chime and phone alert. We often miss calls because people have walked away by the time we get the phone alert and open up the app on the phone.
