I have Hikvision cameras for outside the house. I have one location inside the house that can oversee the entrance, kitchen and back door. Considering this, I want to install one PTZ camera (I only care about the P and maybe T). Also I want the camera as hidden as possible (just the dome). This led me to the Hikvision DS-2DF5286-AEL which only exposes the dome (my outside DS-2CD2132 also exposes the "socket/base" and can't PT). However, the 2DF5286 is listed for $1,700 which is WAY beyond my budget. What alternatives are there that also work with Blue Iris?
