Your setup sounds interesting, Could you tell me how you set this up? I do have a Z-Wave system as well as several Hik cameras.
Thanks
I use a similar setup. My doorbell is integrated as a zone with my security system (Elk M1), this is integrated with my lighting controller (ISY), so when the doorbell is pressed, the ISY posts an HTTP message to a raspberry pi that is just running a small netcat listener, when it gets a certain HTTP post to it, it'll cURL my Hikvision front door camera. Then, it'll take this and, using Pushbullet, post an Android notification to my phone. All this takes <10 seconds, much quicker than I can get to my actual door.
