I am not sure I even want to know what is so sensitive on what you want to put cameras on! there are rule/laws and human decency to always consider -
wired or radio (if it isn't wired, it's radio) - it can potentially be hacked. wifi, BT and cell are all radio. your cell phone up against your head is transmitting RF to work.
I just can't tell if "trail cam" is what you really need, or a fixed CCTV setup, since you want to get it to a PC or DVR.
even wired connections can be "hacked". the BLE blutooth actually make you start with their software - pretty slim chance of someone having the correct software to get to it to turn on the WiFi, which usually turns off in a couple minutes, needing the bluetooth to turn it on, and it isn't a wide open WiFi. (most of the trail cams have some security on the WiFi)
if you want to record it on a PC or DVR - you have to get a signal to from the camera(s) to the recording device.
good camera placement, and probably the 940 nanometer infrared would go a long ways to not drawing attention - the 940 NM isn't visible to the human eye, and from what I have observed, very few animals see - I get some amazing shots with those.
these cameras are likely more secure than a cell phone, partly because a WiFi search won't bring them up unless a person has turned them on for a session. if you aren't going to be taking them "into the wild" - than a standard DVR (or appropriate setup PC) would be the thing for a hardwired CCTV system, not trail cameras. you can get some relatively decent quality low cost from places online. I hesitate to put brand names in here, or store names - but will suggest the huge corporate online place most of the country seems to use, or there is a place called supercircuits that can be quite helpful. think of it needing to be a system - and matching your particular needs with the appropriate gear.
video is simple, but there are lots of levels of quality out there - using one place to get setup can make sure you get the most out of it for what you are doing.
the place I mentioned has some decent quality affordable DVR's as well as cameras.
Good luck!
