I see this thread has had no action for about two years. I've spent months researching trail/game cams and finally pulled the trigger Friday so figured I'd update here. I went with the Tactacam Reveal X Pro.
It's a cellular camera (has it's own 'phone' plan through Tactacam). Sends photos right to you so you don't even have to go out and check the card. You can request instant send, daily once, twice, etc. Many custom settings on the app. You do not have to buy a plan if you just want to just go out and pull the sd card. Tactacam only works on Verizon and AT&T networks so if those services are shitty on that property, no need for the cellular plan. I bought three of these for different properties.
Also, any picture it sends, you can request a 10 second video of that picture. It costs extra after a certain amount I think. I opted to get unlimited pictures and videos. It's nine bucks a month for that.
As far as batteries, it takes 12AA. You can use cheap ones, lithium, etc. Tactacam also sells a rechargeable lithium pack. I bought two of those. They also make a solar panel with its own battery pack. I bought one of those.

A company hme also makes a solar 12v battery kit that works with these cameras and supposedly can last a year. I may pick one up.

Also, there are tons of review videos on YouTube and people will walk you through the app, features, settings, etc. Very user friendly.
