So, I wired Cat6 throughout my new construction and bought a new Hikvision NVR (DS-7716NI-SP/16) and a stack of various Hikvision cameras. So far, so good. However, there are one or two spots that I "missed" where I now wish I had run some additional cables. There is power in those spots and I'm wondering if there's some way to add one or two wireless cameras to my otherwise completely POE setup?

I have a Hikvision DS-7716NI-SP/16 connected to (among other things) a Hikvision Compact Dome camera with two-way audio (DS-2CD2542FWD-IS). I don't have anything connected to the camera (like a speaker) besides the NVR via POE (Cat6). Should I be able to record audio? (I don't expect it has a speaker for the two-way feature, but I'd love to record audio in the room.) I was led to believe that I can, but I'm not able to do so and the iVMS-4200 software doesn't seem to want to let me.

I'm concerned about folks breaking into my cabin in the woods and attempting to cover their tracks by breaking my NVR. I'm considering putting an old, maybe broken or partially broken (as in maybe the lights still function) NVR with some "cables to nowhere" as a decoy if they decide to try to smash/steal one. Anyone done anything like this (or have a broken NVR they might part with)?

Problem with "web" is my internet connection is over cellular and is less than 1MB upload.

When a camera indicates this, is it describing stereo microphones or some bi-directional audio (like mic + speakers) feature or something else?
