Trail Camera Discussion of Manufactured Cameras.

"seems to indicate that "heat" is not the determining factor "

Here's a quote from the Wikipedia citation -- An individual PIR sensor detects changes in the amount of infrared radiation impinging upon it, which varies depending on the temperature and surface characteristics of the objects in front of the sensor.[2] When an object, such as a human, passes in front of the background, such as a wall, the temperature at that point in the sensor's field of view will rise from room temperature to body temperature, and then back again.

The PIR sensor picks up the difference between something warm moving in front of it and the temperature of things in the background, so anything that's well insulated may not be detected. If you've seen deer walking around or bedded down with a thick layer of snow on their backs you can see how well insulated they are. Deer and most other mammals that are active in the winter are much better insulated than we are, even with our warmest winter clothing -- don't try spending a winter night at -20 laying in the snow like a deer or coyote. The control boards for homebrewed trail cameras can be adjusted to vary the sensitivity, but none of my commercial cameras have that adjustment.

that doesn't explain how grass moving from a breeze will set a cam off though. or rainfall and snowfall setting off a cam. movement sets them off more than temperature variances it seems.

I am biased but so far my Ridgetec lookout is proving to be very reliable and stable. It still needs improvement like any camera but I am pleasantly surprised at the long term stability of the platform knowing the complexity of what is going on under the hood.
I have bought bushnell, reconyx, browning trail cameras, and now I turned to the hug of WingHome trail camera, I can't say anything about the these brand in few words. I can only tell you about the feedback of using WingHome brand.

If I had a time machine I would go back and buy WingHome at first because I have had one that has been in the woods everyday since 2018, that is the bee's knees!

All in all, relatively low price, super high quality!

These two photos below are taken by WingHome 350C trail camera.

I've had my old bushnel black flash for around 10 years and it's been abused and neglected, battery life is killer and it just wont quit. They didnt have a cellular camera that worked in canada at the time of needing one and I went with uway, it was a solid camera but just didnt live up to my expectations. Then I went into a summit 4 and the the lookout. While it's been a bumpy road with ridgetec initially (summit4), the customer service is what has been the absolute top notch selling feature in the long run. Plus I love my lookout, no other brand has the features the lookout has. I have 2 lookouts and I had a bit of a sensitivity problem with one of them and some other issues right after they came out. As far as I can tell, all problems I had have been ironed out with updates and sim card swaps to at&t. I'll most likely be buying another lookout before fall as well.

My next most reliable camera is the Exodus Lift II and it has a 5 year warranty. Over the years I've had some type of issue with all of the other camera brands out there like covert, spypoint, browning, stealth, moultrie, cuddeback, hawk, bushnell and primos.
Well my experience with the Exodus isn't very good. I bought two and ended up sending both in because they both simply quit working. I was testing them in my backyard, turned them on, both powered up and took pics/videos for a week/weeks and then simply would quit and not power back on. One of the replacements that I received in July started showing SD Card Full but only on 32gb Class 10 cards. I sent it in last week and waiting on yet another replacement.

What I always wonder is how a deer can magically show up in the middle of a picture. I've had this happen with every camera I've ever owned which is about every brand you can think of.

simply the cam's trigger speed/sensitivity, etc.
some sensors seem to be better than others, and then, the sensors have to jive with the lens. I've had a video even, where there's nothing there, then a doe just APPEARS in the center of the frame, as if scotty beamed her there.
