AA Lithium batteries
This is what www.Trailcampro.com
has to say:
If you live in an area with cold weather, I would strongly recommend the AA NiMh rechargeable batteries and the NiMh charger. NiMh is unaffected by cold weather unlike alkaline batteries. These batteries can also be charged 1000 times.
Now why waste time and money and get MiMh batteries when you can get one AGM rechargeable battery that is warranted to last 4 years regardless of the temperature. The cost $89.00 dollars or go with the Lithium and buy them each year at $21.00 x 4 = $84.00.
This unit or cam also comes with a 6volt external port from the manufacture. This is just in case you want to use a solar panel with your camera and external battery during the colder temps.
One more little detail, this camera uses a ton of power compared to the wildview. for this unit it's as follows:
Power Consumption .150mA (+450mA when IR-LED lighted)
And the wildview are only .003mA stand by with 150mA when using flash.
What does this all mean, well if you are in a area that sees a lot of animal activity then chances are that your batteries aren't going to last very long at all.
My setup I usually get 100 pictures a month in the winter and 300 a week in the summer, spring and fall months, I have yet to lose power in my units.
The option is yours and like I was saying I am here to help your process of getting the best results for your cameras.
All year around 24/7 365 and like me if you live 100 to 200 miles away from each property you don't want to have to go back a forth to each cam making sure that your batteries are not dead, this is a waste of my time and money.
These cameras also cost between 199.00 to 249.00 although I will agree if they can walk the walk and talk the talk then they maybe worth getting. but still not really in your price range.
The trigger speed is about 1.024s which changes depending on the burst mode setting.
From 7, 11, 15 seconds apart, there is a good possibility that you will get some butts after all especially if they are coming from the other direction.
