hello all. merry christmas to all. new member asking for help. I was broken into 2 weeks ago. the window guards were pulled from the wall. im on ground floor. rented apt. nothing was stolen although I think they didnt look in the right places. I cant take any chances again. id like to add 1 security camera (dont need more as its a small 1.5 room apt.) that can do the following: -alert to my phone of perimeter activation and see real time video of home. -record at high resolution/ high fps (I always notice on news footage the security cam always shows low fps and bad resolution you cant make anything out or who the thief was) -Id like to speak from my smartphone ,through the cam to warn the burglar verbally have 2 way communication with them if possible. or through my sound system. I plan on trying to connect the camera to a wall mounted surround speaker ill remove the internals, so itll be la ninja mode -record with motion activation and record immediately away from the cam to small rasperry pi pc HDD, or offline and camera card.. if they steal the cam -no footage I was considering this camera hikvision DS-2CD2442FWD-IW because of its flat profile to install into a speaker. looking to get the 4mm model as 2.8mm will be too wide. no experience with security cameras prior to this. my question is it ok using a small raspberry pi pc (hidden) with hdd used to record the footage vs buying a video recorder? also, is it possible to record the HD video stream to my phone with an app? im trying to see if there is a way to do it without paying cloud services.

zum help friends ?
