Sorry about the book:
We have two tactacam 3 pros and two stealth 360 degree version 2s. Have lithium batteries and solar panels for both. Figure $250-$300 to set each camera up like this.
Data plans are similar, you can do by the photo or unlimited. I think am paying $120/yr for unlimited with on-demand photos for both brands (think second camera is less). The live view is extra, videos might be extra. On-demand takes a picture "right now".
You have to use Rain-X on the lenses - both will "dew" up and be cloudy at times - my browning trail cameras do this too. We get quite a bit of dew and thankfully the Rain-X helps.
Deer will look at the 360s more than the Tactacams or Browning trail cameras at night. Possibly the IR flash and possibly cause you need to set the 360's at waist high for good photos - eye level for deer.
The Tactacam photos are more grainy and a stranger's face is not guaranteed to be clear. The night photos are the same - Tactacams aren't showing antlers very well at 50-60 feet. We have a Tactacam and a 360 set for security. The 360 photos are better and I'm sure there are some brands that are even better.
The 360 is a serious camera - I check out the entrance doors to 2 buildings and the upper, middle, and lower pastures with it every day when it sends me a daily 360 photo. It isn't perfect but would need 4 regular cameras just to do this - it is barely behind the camp bld corner if walk/drive in the driveway - once you see it, I already know you are there. Try to come around the far side of the building and It gets you there too. Very neat.
Oh - last comment. FWIW - My cameras (Browning trail cams, Stealth, Tactacam) all trigger strongly to vehicles - cars, trucks, and tractors - can't set them facing the road or would get EVERY vehicle - even significantly outside detection range.
