A. Resolution level, Users Reviews, Price, Quality, Internal Features, Weather capability.
B. Price: You might want to look at the price of the camera you’re interested in and see if it’s worth the spending. For example it wouldn’t make sense buying a camera for $1000 instead of one for $800 that are almost identical in quality and performance.
User’s reviews: Reading and listening to what people who have actually owned the camera can be very help full. Just cause the it’s expensive or “cool” looking doesn’t mean that it’s going to last or perform like you want it to.
Weather Capability: Knowing if your able to record in the cold winters without worrying much is a great thing for us. Not just in the cold but all weather conditions. If your camera isn’t compatible in those environments then you might regret buying it.
