Not really sure where to put this, but since this involves networking and security I figure the subject may fit here. I'm thinking about getting a Smart Doorbell and was wondering if anyone has any experiences with any of them? More specifically, I'd like to know if anyone has a Smart Doorbell hooked up to their 3rd party home security system and doesn't have to rely on the app that all the different devices come with? I don't really have a specific doorbell in mind, I'm just looking at the most popular ones at this time. My security system allows for eight cameras hardwired or a mixture of hardwired and wireless. I already have a couple wireless Foscams on the system to go along with the 4 wired, I'd just like to add the doorbell as well. Google does not seem to be my friend finding this information. Before anyone asks, I don't care about using the app for two way communication or any of that stuff, I just want it to record to the security system when there's an alert and let my security system FTP off site like the rest of the cameras do. Thanks.
