the one that the 2nd post links to is the one with a normal flash. you’ll see it go off at night. the one in the simon king vid has the black IR flash and won’t be seen going off at night. best pay a little more for the IR flash as if you get a prowler and they see it go off they may be tempted to smash up/ steal the camera.
the delux tree bracket thing is very useful as well.
also, a tip is to rub mud all over the unit (avoiding the lenses/ sensors) or do what I did and glue tree bark flaxes to the unit. It blends in to tree bark better and the roughing up of the otherwise smooth profiles of the unit helps it blend in to the outdoors no end.
Also be aware, swaying tree branches and flies will set the thing off if you’re not careful in placing it and the result will be 000’s of stills with no interest..
